Answer:
Lava or magma is considered to be in molten state while the earth's mantle is layer of rocks that changes its state
Explanation:
Earth's mantle is composed of solid rocks that exist in a liquid form, the upper layer is that of the Asthenosphere and the layer of the mantle is further divided into upper, lower and transitory layers. Being the massive and most widely occurring layer covering the planet. It has a layer of silicate between the crust and outer core. It is approximately 1600 km thick. The upper mantle contributes to the tectonic activity as the rocks in this layer are malleable. There are 15 major and minor slabs above the layer and lava i.e the molten rock is burned inside the magma at grater depths and as there exists water in the mantel the transition zone is evident from the upper and lower exchange of minerals.5 (10 pts). Describe the difference between a primary producer, primary consumer and secondary or tertiary consumer, and give an example of each. What happens to the flow of energy between these levels, and what happens in terms of the concentration of toxins like DD
Answer:
Food chain as given below
Explanation:
A consumer is a living creature in the food chain that eats other consumers and maintains a balance in the food web. Primary producers are all green plants that prepare their food by their ability to utilize the sun's energy and convert that available raw energy into starch in their body by the process of photosynthesis. These Autotrophs take up the organic matter through their roots in the form xylem and phylum and giving oxygen in the air. They form the base of the food chain on which are dependent Herbivorous like sheep, goat, cow, etc. The secondary consumers are called the Carnivorous, like the lion, tiger, etc that feed on the bodies of herbivorous. Above this level is that of Omnivorous i.e both plant and animal eaters like the crow, man, and cat. As stated by the law of thermodynamics energy can neither be destroyed nor created but transforms itself. The flow of energy at each trophic level gets successively transferred to the next trophic level from primary to secondary tertiary and so on. Likewise, toxin concentration in trophic levels increased each level upwards and leads to biomagnification that is harmful to the entire food chain.Question 21 1 pts In what year did GPS become free to the public? a) 1983 b) 1965 c) 1972 d) 1941

1.name the three types of plate boundaries(and their subtypes), and give an example where each can be found
2. what are the relations, if any, of volcanoes and earthquakes to plate bound-aries? See"plate tectonics and people" on the website
3. what type of plate boundary is found in southern California, and what is the name of the fault zone and the type of fault?
3a. Base on what you know about plate boundaries,would you expect to find volcanoes presently formin in southern california? why?
Answer:
As given below.
Explanation:
The three types of plate boundaries are Divergent, Convergent and Transform boundary. The transform boundary of the plate tectonic rift is found near the entire Californian coast. These boundaries are demarcated by shear zones, the plate tectonic boundary of divergence is found in place of the splitting of the oceanic crusts like in mid-oceanic ridges. The third boundary is of convergence in nature, which is found in most of the parts of the world like the Pacific and North America plates. If any volcanoes and earthquakes on the plate boundaries arise then they are bound to be cause and consequence of two lighter and heavier plates colliding with each other and as result, the plates burn against one another and create seismic shocks. Southern California has transform boundary and Fault is the San Andreas Fault that extends to 1,200 kilometers. The active fault with shallow earthquakes and Dextral motion. No as the shear zones do not have volcanic activities, and southern California is drifting to the western sides due to the movements along with the pacific plate.A sewage treatment plant influent is estimated to have a typical BOD5 value of 320 mg/L. What efficiency must the treatment plant have in order to meet the NPDES BOD5 requirement of less than 30 mg/L? Note: Your calculated efficiency must be entered with units of %
Answer:
The required efficiency of BOD5 removal of the plant needs to be at least 91%
Explanation:
Even though a WWTP (Waste water treatment plant) has several unit operations, it needs to have an overall treatment efficiency. In this case, it is only required to know how much BOD5 do we need to lower by removing organic matter from the water. It goes as following:
[tex]Efficiency(%) =\frac{actual concentration-goal concentration}{actual concentration}*100%[/tex]
This will work for any efficiency, for any parameter you need to define. They need to be in the same concentration unit, of course.
Replacing known values, we have:
[tex]Efficiency (%)=\frac{320 mg/L-30 mg/L}{320 mg/L}*100%= 90,625%[/tex]
Which we will approximate to 91%, because decimal percentages do not say anything and are not currently used.
Question 9 1pts of the Earth's atmosphere is below 26km. O 50% O 100% O 48% 98%
Answer:
Earth's atmosphere is below 26 km is composed of 98%.
Explanation:
Troposepher marks the boundary for most of the convective activity to take place on the surface of the earth's this place consist of 99% of the total space for the all-weather phenomenon to occur and as a result of which is considered to a homogeneous sphere. Here the water vapor, dust particles, and other gaseous bodies are found and thus this layer is a life-supporting layer full of oxygen and hence, comprise all biotic components like the plants, animal and man. Above this layer there are drastic changes in temperature with increasing height as the atmospheric pressure at higher altitudes decreases and so does the life-supporting layer, it can be noted that the layer that protects the earth i.e ozone is found in the mesosphere at an altitude of 30 kilometers. Rest most of the weather phenomenon takes place here as it sets the stage for weather patterns as convective currents coming from the equator can't pass this layer."Man has too long forgotten that the earth was given to him for usufruct alone, not for consumption, still less for profligate waste." What does Marsh mean? (About 100 – 200 words). Word limit is a general guideline.
This question is from the global environment by thomas easton from the man and nature . prompt
Answer:
The marshes are defined as the type of wetland where the water covers the ground surface for a long period of time. Here, the trees are absent and are mostly dominated by the grasses and other small herbivore plants. They are commonly formed in delta type of environment where the rivers adds water into the seas. It forms an isolated and distinct ecosystem.
The marshes in nature, behaves like a filtration process as the vegetation that are present in marshes takes up more amount of nutrients for their growth and expansion. But, if it does not use up these excess nutrients then it cause water pollution comprising of nitrogen and phosphorous.
They also plays an important role in the reduction of damages that are caused by a flood.
The marshes are sometimes seasonal and it occurs when the height of the river level is relatively high, and it floods the grassland areas.
The marshes are of three types-
(1) Tidal salt marshes
(2) Tidal freshwater marshes
(3) Inland freshwater marshes.
How are changes in atmospheric CO2 over time recorded in the geologic record? List at least 4 tools/methods for reconstructing past atmospheric CO2.
Answer:
boron and carbon isotope, Phytane, Ice cores, Corals, Lake and ocean sediments etc.
Explanation:
Drillings in ice cores like within ice sheets of Greenlands, Antarctica started in 1956. Collecting core samples of 4 and a half inches and use of molecules of water O 16 and 18 that helps to determine the past atmospheric carbon. Corals, skeletal rings have bands of paleo-climatological information and as their body is made of the calcium carbonates these limes creating organisms help to determine the atmospheric concentration of carbon on prehistoric earth. The use of oxygen isotope in lakes and oceans has given data related to the content of ocean sediments, and values deposited in clay and sand. The use of phytane a diterpenoid alkane that breaks down chlorophyll is used to estimate the ancient Co2 level.Why would we find more of the latter in planets such as Earth that formed near the Sun?
Answer:
As the size, density, thickness, and velocity all coordinate with the distance from the sun, hence the rocky planets and gaseous planets differ from each other.
Explanation:
Our solar system consists of eight planets and one dwarf planet all are arranged in there the internal composition of elements the first four planets near the sun are made of rocks and have a core rest Jupiter, Saturn, Uranus, Neptune are made up of gaseous substances like Helium and Hydrogen just like the sun. Jupiter is the second densest planet in the solar system based entirely on gases and others like Neptune and Saturn made up of ice and magnetic core and terrestrial plants lack such due the violent solar winds blasted off this primitive atmosphere some 4.5 billion ago. Thus the gaseous bodies formed away from the galactic core that is the sun and have lower densities and planets like mercury have the highest densities due to their internal structure is used like earth and less distant to the sun and share some sort planetary atmosphere with that of the earth like venus.Planets like Earth, which formed near the Sun, have more rock and metal due to high temperatures. Outer planets, on the other hand, have more ice and gas because of lower temperatures.
Explanation:The reason why planets such as Earth, which formed near the Sun, contain more of certain elements and materials compared to outer planets is due to the temperature gradient in the solar system. The inner parts of the solar system, including planets near the Sun, experience higher temperatures, which cause materials that cannot condense at those temperatures to be absent. In contrast, the outer parts have cooler temperatures, allowing for the accumulation of ice and gas. This explains why Earth and other inner planets have higher concentrations of rock and metal, while outer planets have more ice and gas.
Outer Planets (Gas Giants): Planets like Jupiter, Saturn, Uranus, and Neptune formed farther away from the Sun where temperatures were much lower. In these regions, lighter elements like water, methane, and ammonia were able to condense into ices, along with gases like hydrogen and helium.
Composition of Outer Planets: Due to the lower temperatures, the outer planets have a much higher proportion of gases and ices in their composition. They do not have a solid surface and are often referred to as "gas giants" because of their predominantly gaseous atmospheres surrounding a dense core.

Why does the moon appear dark from space?
But why does it appear bright when observed from earth, especially when it is full moon?
moon look dark in space because the space is not a body it is a black area where there is no tress of light. Our earth is luminous body and the moon is also a luminous body that's why the earth is getting light from the sun in the day and moon in night.the answer is simple due to the movement of earth,sun and moon.
The moon appears dark from space because there is no way for light to travel and be scattered.
People on earth see the moon as bright because of the light that is scattered by the atmosphere.
While in space, it is dark because there is no way for light to travel. Since light is not scattered, the true features of the moon is seen as dark. While in space, because there is no atmosphere, it would always be dark during the day and in the night time.

Did lettuce seed germination respond in a predictable way® Describe the trend AND mention any concentration that did not fit the trend 2. According to this activity and the Background reading, how could acid rain affect specifically impact food supplies
Answer:
Answer
Explanation:
1)Yes, In good growing conditions, lettuce seed will germinate within two to 12 days, depending on variety. Loose-head varieties may sprout more quickly than heading types, but all seeds depend on similar soil, moisture and light conditions to support germination. Growers vary in their estimate of the percentage of lettuce seeds that will germinate per packet, but you can expect 75 to 80 percent of seeds packed for the current growing season to sprout. Rates decline each year, and a packet of lettuce seeds is usually viable for three years.
The germination of lettuce seed (Lactuca sativa) is inhibited at certain temperatures, above the optimum. These temperatures may not prevent growth, however, of seeds which have already started to germinate. This inhibition seems to be largely a varietal characteristic, for the temperature at which one variety will germinate satisfactorily may completely inhibit the germination of another variety. Furthermore, it usually requires a higher temperature to inhibit the germination of old seed than it does that of freshly harvested seed of the same variety. By freshly harvested seed is meant that which is not more than five weeks old. In the case of most varieties, almost complete failure of the seed to germinate occurs at 30° C, regardless of age, although there are a few varieties that germinate fairly well at this temperature.
Lettuce seed germination can be influenced by the availability of nutrients in the soil, such as potassium. Different bacteria strains can impact this availability. Acid rain, arising from human activities like burning of fossil fuels, can decrease the pH of soil, harm crops and reduce food supplies.
Explanation:Lettuce seed germination could potentially respond in a predictable way to certain conditions. For instance, germination might be influenced by factors such as the availability of nutrients in the soil. In a scenario where different strains of bacteria modify the potassium levels in the soil, the germination rate of the seeds could change. Strain 1 bacteria increase the availability of potassium, which is beneficial for the seedlings, while Strain 2 bacteria decrease this nutrient's availability, potentially hindering growth.
As for the effects of acid rain on food supplies, this form of precipitation can significantly lower the pH of the soil, having a harmful impact on crops. Acid rain is caused by human activities that release large amounts of sulfur dioxide into the atmosphere, such as the burning of fossil fuels. When rainwater falls through this gas, it forms weak sulfuric acid, which can damage aquatic ecosystems and contribute to the chemical degradation of terrestrial habitats. In the context of agriculture, this process could lead to a decreased production of crops like lettuce, thus reducing food supplies.

the distance north and south of the equator is measured in degrees of?
Answer:
Latitudes
Explanation:
The distance traveling in the northern and the southern hemisphere from the equator is measured in terms of latitudes. It is expressed in degrees. These are the geographical coordinates that specify a particular location on earth. It ranges from 0° to 90°, where the 0° line is the equator that divides the earth into two halves. And the 90° latitude area in the polar region of both the hemisphere. The earth is bulging at the equatorial region and flattened at the poles.
The latitude plays an important role in the identification of any place on earth.
Thus, the north and south of the equator are measured in the degrees of latitudes.
Why does hardness decrease with increasing molecular weight of the metals in the oxygen compounds?
a.
Larger molecular weight means a smaller valence or charge on the metal, so making the bond between them weaker and the hardness lower.
b.
Larger molecular weight means a stronger magnetic field around the metal, making the electrostatic bond between them weaker and the hardness lower.
c.
Larger molecular weight means a larger size metal, and the nucleous of the metal will be farther away from the oxygen in a large metal than a small one, making the bond between them weaker and the hardness lower.
d.
Larger molecular weight in the metal means the oxygen also gets larger, which makes the bond between them weaker and the hardness lower.
Answer: Option (A)
Larger molecular weight means a smaller valence or charge on the metal, so making the bond between them weaker and the hardness lower
Explanation:
Hardness decrease with increasing molecular weight of the metals in the oxygen compounds, the reason for the decrease in hardness of the metals is due to chemical repulsion (inter molecular forces between atoms) which is greater when the metal and oxygen are close to each other making the compound hard.
If the repulsion is smaller, the compound has less hardness. So when the molecular weight is large, it has smaller valence or less charge on the metal which makes the bond weaker and less hard.
Hardness decreases with increasing molecular weight of metals in oxygen compounds because larger metal atoms have their nuclei farther from the bonding electrons, leading to weaker metal-oxygen bonds and lower lattice energy.
Explanation:The reason why hardness decreases with increasing molecular weight of the metals in their oxygen compounds can be associated with atomic structure and bonding. When a metal in a compound has a larger molecular weight, it typically means the metal atoms themselves are larger. This is because these atoms have more protons in their nuclei, as well as more electrons to shield the attractive force from the nucleus to the bonding electrons.
As the metal atom size increases, the nucleus is farther away from the bonding electrons shared with the oxygen atom (option c). This results in a weaker metal-oxygen bond, making the compound less hard. Moreover, this size increase leads to larger atomic or ionic radii down a group in the periodic table, affecting the lattice energy. The lattice energy decreases as the ionic radii increase because there is a longer distance between the ions' nuclei, leading to less electrostatic attraction and therefore a softer compound.
The information given about the acid strength as a function of electronegativity and the behavior of alkali metals does not directly answer the question regarding molecular weight and hardness in metals bonded with oxygen, but it does provide context to how other properties are influenced by the electronic structure of atoms.

A drainage basin bordering the sea has an area of 7500 km2 . The average precipitation for this drainage basin is 900 mm year-1 . The average surface water flow at the outlet of the drainage basin equals 22.5 × 108 m3 year-1 . The average groundwater flow to the sea is 100 mm year-1 . The averages are determined for 30 hydrological years. Determine the average actual evaporation in mm year-1 and m3 year-1.
* The average actual evaporation is **-22000 mm year-¹**. This negative value indicates that the actual evaporation is less than the precipitation and groundwater flow combined, resulting in net water accumulation within the basin.
* The average actual evaporation is **-165 million m³ year-¹**.
Here's how to determine the average actual evaporation in both mm year-¹ and m³ year-¹ for the drainage basin:
**1. Calculate the total precipitation:**
* Multiply the basin area by the average precipitation:
Total precipitation = Area * Average precipitation
Total precipitation = 7500 km² * 900 mm year⁻¹
Total precipitation = 6750000 m³ year⁻¹
**2. Calculate the total water flow:**
* Add the average surface water flow and the groundwater flow converted to m³ year⁻¹:
Total water flow = Surface water flow + Groundwater flow (converted to m³)
Total water flow = 22.5 × 10⁸ m³ year⁻¹ + (7500 km² * 100 mm year⁻¹ * 1000 m³/km²)
Total water flow = 22.5 × 10⁸ m³ year⁻¹ + 750 × 10⁶ m³ year⁻¹
Total water flow = 232.5 × 10⁸ m³ year⁻¹
**3. Calculate the actual evaporation:**
* Subtract the total water flow from the total precipitation:
Actual evaporation = Total precipitation - Total water flow
Actual evaporation = 6750000 m³ year⁻¹ - 232.5 × 10⁸ m³ year⁻¹
Actual evaporation = -165000000 m³ year⁻¹
**4. Convert actual evaporation to mm year-¹:**
* Divide the actual evaporation in m³ by the basin area and convert to mm:
Actual evaporation (mm year⁻¹) = Actual evaporation (m³) / Area
Actual evaporation (mm year⁻¹) = -165000000 m³ / 7500 km²
Actual evaporation (mm year⁻¹) = -22000 mm year⁻¹
Therefore:
* The average actual evaporation is **-22000 mm year-¹**. This negative value indicates that the actual evaporation is less than the precipitation and groundwater flow combined, resulting in net water accumulation within the basin.
* The average actual evaporation is **-165 million m³ year-¹**.

The items in the list that are minerals are: 1. Gold nugget, 3. Quartz, 4. Cubic zirconia, 5. Obsidian, and 6. Ruby. The items that are not minerals are: 2. Seawater, 7. Glacial ice, and 8. Amber.
According to the geologic definition, a mineral must meet the following criteria:
1. It must be naturally occurring, which means it cannot be man-made or produced artificially.
2. It must be inorganic, meaning it cannot be derived from living organisms.
3. It must have a definite chemical composition.
4. It must have a crystalline structure, which means its atoms must be arranged in a regular, repeating pattern.
Let's apply these criteria to each item in the list:
1. Gold nugget: It is naturally occurring, inorganic, has a definite chemical composition (Au), and a crystalline structure. Therefore, it is a mineral.
2. Seawater: Although it is naturally occurring and inorganic, it does not have a definite chemical composition, nor does it have a crystalline structure. Therefore, it is not a mineral.
3. Quartz: It is naturally occurring, inorganic, has a definite chemical composition (SiO2), and a crystalline structure. Therefore, it is a mineral.
4. Cubic zirconia: It is a synthetic material and not naturally occurring, so it does not meet the criteria to be classified as a mineral. However, if we consider naturally occurring zirconia (baddeleyite), it would be a mineral because it meets all the criteria: it is inorganic, has a definite chemical composition (ZrO2), and a crystalline structure.
5. Obsidian: It is naturally occurring, inorganic, and has a definite chemical composition similar to granite. However, obsidian is sometimes considered a mineraloid because it does not have a regular crystalline structure, but rather a glassy structure. For the purpose of this question, we will consider it a mineral because it meets most of the criteria.
6. Ruby: It is naturally occurring, inorganic, has a definite chemical composition (Al2O3 with chromium impurities), and a crystalline structure. Therefore, it is a mineral.
7. Glacial ice: It is naturally occurring, but it is not considered a mineral because it does not have a definite chemical composition (it can contain various impurities) and its structure is not crystalline but rather hexagonal.
8. Amber: It is a fossilized tree resin and is organic in nature, not inorganic. Therefore, it does not meet the criteria to be classified as a mineral.
In summary, the gold nugget, quartz, cubic zirconia (if naturally occurring), obsidian, and ruby are minerals, while seawater, glacial ice, and amber are not.
The gravitational pull on the ocean at night causes the water to more or less bulge towards the moon. I wonder if out in the ocean the same thing happens but since the ocean is so vast, it isn't noticeable since it is away from the shoreline, does this occur out in the ocean as well? How does gravitational pull occur?
Answer:
Earth's rotation and gravitational attraction of the sun and the moon to some extent are responsible for the motion of tides in the oceans. As the oceans are so vast there exist a cyclic flow water.
Explanation:
As the earth has its gravity and so does the other phenomenon like stars and moon have there thought this is not felt directly as the tidal bulges that are seen around the earth occur at two times in a day and two times at evening time due to the course of earth rotation having a cyclic time of 12 hours. The gravitational pull of the moon is not that strong but since it is close to the earth's surface the tidal bulges are felt on a full moon day and a new moon day as the oceanic currents rise by the gravitational attraction of the moon at night. In the day this is noticeable, as the sun has a large attractive force on the planet derives the winds and pressure belts around the globe, When these celestial objects all fall in the same line both ends on earth experience two small and large tidal bulges on east and west sides.Question 22 1 pts Which of the following represents the greatest source of domestic water usage in the U.S.?

Investigate two ways in which water shortages, erosion, water
diversion, floods or contamination of a water resource, or other
water processes have affected human history. How did humankind meet
the challenges of the impacts?
Answer:
The earth undergoes various types of geological processes that control different conditions on the earth's surface. When these processes are very severe along with human activities, then the organisms and humans have to face a lot of difficulties. Due to the occurrence of heavy flood in any region, the people lose their houses, the agricultural crop fields are affected by losing their fertility. Water is one of the essential elements for the survival of life and it creates havoc when they are contaminated because they become unfit for drinking. So a lot of problems is needed to be faced due to natural calamities like floods, tsunamis, and droughts.
Human beings can meet up the challenges of these impacts by undertaking certain steps-
(1) The waster materials produced from the industries and factories must be collected and dumped somewhere instead of allowing it to get mixed up with the rivers and streams.
(2) The dams must be properly constructed and should be periodically surveyed.
(3) Water must be preserved and make proper and minimum use of it.
(4) Pollution must be reduced as much as possible.
(5) Afforestation must be done so that the plants and trees can hold the soil and maintain its fertility, rather than getting eroded.
We can determine the age of most Mesozoic rocks through "carbon dating," which relies on the radioactive decay of Carbon-14.
true or false?
Answer:
The statement is false.
Explanation:
Carbon dating using the radioactive decay of Carbon-14 is reliable up to 50,000 years. It is mostly used for living organisms that were younger than that period. Rocks are much older than 50,000 years and rocks from the Mesozoic era would not be able to be dated using Carbon-14. It will require another element with longer half-lives in order to determine ages higher than 65 million years ago.
Q1 Which is the best description of a climate forcing?
Something that warms the planet
Something that cools the planet
Something that creates an energy imbalance for the planet
Something that balances the energy of the planet
Answer
Something that creates an energy imbalance for the planet
Climate forming is something that can create an energy imbalance for the planet. The difference between incoming and out going radiation is called the planets radiative forcing(RP). A climate forcing factor will change the climate of the Earth.It can either cause heating of the plane , positive RF or cause cooling of the planet, negative RF.
Question 14 Multiple Choice Worth 3 points) Which of the following contributes to the movement of tectonic plates? 1. deposition of sediment on the ocean floor II. push of newly formed crust III. mantle convection I only Ill only I and II ll and III I, II, and II
The push of newly formed crust and mantle convection primarily contribute to tectonic plate movement, while sediment deposition doesn't significantly influence it. The correct answer is D) II and III.
Explanation:The movement of tectonic plates is influenced by several factors. The primary driving force is mantle convection, a slow process by which heat escapes from the Earth's interior, causing an upward flow of warmer material and the slow sinking of cooler material. This convection causes the molten rocks of the asthenosphere to rise and fall, creating forces that make the tectonic plates move.
Another contributing factor is the push of newly formed crust at divergent plate boundaries. For instance, as new crust forms at the mid-ocean ridge due to causing the old crust to move aside, which induces plate movement.
However, the deposition of sediment on the ocean floor typically doesn't have a significant effect on plate movement. It can add weight to the oceanic plate, but this doesn't contribute substantially to the overall forces driving plate tectonics.
So, among the choices given, both the push of newly formed crust and mantle convection contribute to the movement of tectonic plates. Therefore, the correct option is D) II and III.

Which geographical feature formed the northern border of the Mauryan Empire?
A. Narmada River
B. Himalaya Mountains
C. Deccan Plateau
C. Thar Desert
Final answer:
The northern border of the Mauryan Empire was formed by the Himalayan Mountains, which served as a natural boundary and provided protection against northern invasions. The correct option is (B).
Explanation:
The northern border of the Mauryan Empire was formed by a significant geographical feature known as the Himalayan Mountains. These formidable peaks, arising from the collision of the Indian Plate with the Eurasian Plate, have played a crucial role in the physical geography and cultural history of South Asia.
The Himalayas not only provide a natural boundary between South Asia and East Asia, particularly between India and China but have also influenced the religious and cultural practices of the civilizations that flourished around them.
The Mauryan Empire, which is notable in history for its extensive reach across South Asia by 250 BCE, included the rugged terrain of the Himalayas within its northern frontier.
This inclusion of the Himalayas in its borders afforded the empire natural protection and a definitive boundary against invasion from the north. Thus, option B, the Himalaya Mountains, is the answer, as they formed the northern boundary of the Mauryan Empire.

Drinking bottled water may be viewed as a response to scarcity. Which of the following is NOT a scarcity that contributes to the consumption of bottle water?
Group of answer choices
-agricultural scarcity -- water is used only for growing exportable crops and local supplies of water are depleted
-perceptual scarcity--perception that bottled water is safer and healthier than tap water
-techno-economic scarcity -- underdeveloped nations with swiftly urbanizing populations create a demand for bottled water
-hydrological scarcity --combinations of climate, affluence, and human population create a demand for bottled water
Answer:
perceptual scarcity--perception that bottled water is safer and healthier than tap water
Explanation:
Drinking water comes under hydrosphere hence it is a hydrological scarcity and viewed in terms of consumption the water is a natural resource is not distributed evenly as the place which is landlocked doesn't get sufficient water to drink and being a hydrological scarcity it is a combination of climates and weather patterns. The human population demands freshwater that is hard to find with the melting of ice caps and depletion of natural resources and reserves there consumption has increased further 10 times than it was earlier as people wastewater without even realizing that even after purchasing it they still would not be able to afford it. Agricultural scarcity is directly related t the use and discharge of water as water is used in irrigating the plants and used to drive machinery. This includes the technical aspects also.Question 3 Multiple Choice Worth 1 points) In which of the following ways do organisms play a role in the water cycle? 1. Water stored in organisms returns to the atmosphere through evapotranspiration. II. Plants take up water vapor through their roots through the process of sublimation. III. Humans deplete freshwater reserves at both the surface and groundwater levels. I only ll only I and II only I and III only Il and Ill only
Answer:
Option (4)- I and III only
Explanation:
Evapotranspiration is the process by which the plants after absorbing water and carbon dioxide, release the excess water back into the atmosphere. It helps in synthesizing their own food.
The freshwater reserves on the earth's surface are constantly being exploited by humans. The groundwater is exhausted due to pumping and the surface waters are contaminated by the waste materials that are produced from the industries and factories that mix with the rivers and streams. It is also used up for the agricultural purposes
Sublimation is not a process of taking in water vapor by the roots. But it is a phase transition process from solid to gas or gas to solid.
Hence, the correct answer is option (4) i.e I and III only.
