Answer:
There exists continental ans valley glaciers who ages have determined on the basis of rock types and carbon datings
Explanation:
Glaciers were formed some 34 million years ago, in which first small glaciers were seen in Antarctica and that was 20 million years ago as the glaciers froze on to rocks and southern ice sheets were formed. The snowball earth existed from 2.4 to 2.1 billion years ago, at that time Huronian glaciation i.e oldest ice age was built on earth having unicellular mass. As in the earlier phase, the snowball was completely frozen and 250 million years after the big volcanic activity that spread the carbon dioxide into the atmosphere and created the greenhouse gases. Evidence can be taken from the quaternary period of glaciation some 2.58 million years ago. As the ice sheets have gone through the multiple periods of growth and retreat as in the interglacial period the ice melted and retreated. Roughly about 41,000 million years ago the tilting of axis of the earth had a major effect on the ice sheets around the globe.If the number of electrons in an atom is 39 and the mass number for the same atom is 90, calculate the the following for this atom: a) the number of protons b) the atomic number c) the number of neutrons d) What is the identity of this element?
Answer:
no. of protons = 39
atomic number = number of protons = 39
number of neutrons = 51
element is Yttrium
Explanation:
given data:
number of electron is 39
mass of atom is 90
We know that atoms are neutral because +ve charged protons is equal to no of -ve charged electrons.
we know that:
atomic number is equal to number of protons,
and atomic mass is the summation of no. of protons and no. of neutrons
number of protons = number of electrons
from the data given:
a) No. of protons = 39 (since number of electrons = protons)
b) atomic number = number of protons = 39
c) number of neutrons = atomic mass - atomic number
= 90 - 39
= 51
d) element is Yttrium
How is pollution related to sustainability? Sustainability must incorporate ways of halting pollution entirely Sustainability incorporates methods of decreasing pollution. Sustainability needs to find a way to increase pollution. Sustainability uses the energy of pollution to drive the economy Sustainability and pollution will both increase in the future.
Answer:
Sustainability must incorporate ways of halting pollution entirely
Explanation:
The concept of sustainability in the production process means that an economic activity is performed without causing further damage to the environment. For example, for a paper mill it consumes 100 trees in the production process. To be considered sustainable, this firm must generate the benefit that these trees brought to the environment. This can be done in many ways, such as planting trees or directing funds to environmental causes. In other words, an economic activity is considered sustainable if it generates benefits to the same extent as the harm caused by its activity. If the company has polluted the environment, it must take steps to reverse the pollution it causes to be sustainable.
plate boundary, what is the result O A mountain belt, like the modern Himalayas 0 A continental volcanic arc like the modern Andes. O Earthquakes, but no volcanism, like the modern San Andreas Fault in California.
Answer:
All the above
Explanation:
The plate boundary is the result of movements in the latest either through the divergence, convergence or the formation transform or rift valleys. The occurrence of the earthquakes and volcanic eruptions around the zones of mountain belts and various other events led to the volcanic arcs. A Mountain belt-like system of the Himalayas in Northern India is a result of the orogenic upliftment of sediments bright from the Tethys sea and splitting of the Indian subcontinent from the Australian plate to collide with the Eurasian plate. A continental volcanic arc forms due to the lava a magma that originates in the form mantle plums produced due to the burning of the lighter plate over the oceanic plate and volcanoes like the Andes form when the slab pulls the plate to the deep trenches. And the san Andreas fault in California is a transform fault with dextral movements on both sides as the landmass is drifting westwards.Explain your interpretation of "sustainable development" as it might apply to
a)World population growth
b)The downtown core of a city
c)A thriving agricultural area
Answer:
"sustainable development"
Explanation:
Sustainable development implies that development that is based on the judicious use of resources as this implies over the entire earth. In terms of world population, this sustainable development can b understood in the form of a population explosion where the growth needs to balance and sustained in a fashion that does not affect the environment badly. A thriving agricultural area like the Ganges river system which is quite vulnerable to the changes brought in by the climatic reversals and hence needs to take care of and so that the areas don't have any drawbacks and development is not hindered. From the core of a city, it has to look at greener buildings and eco-friendly landscapes.Answer:
Explanation:
Sustainable development is the process of conservation of resources so that they remain available for present as well as for the future generations. The dynamics of the sustainable development can vary at different levels.
a)World population growth: The world population should be controlled from incremental increase every year more than the standard expected numbers. Thus resources conservation can become an issue under such conditions.
b)The downtown core of a city: A the city level the control in increase in size of the population should become the priority as well as the conservation of resources and the environment should be taken into consideration.
c) A thriving agricultural area: The agriculture area should be preserved by adding adequate amounts of minerals present in the manure and by crop rotation. This will help in preserving the quality of soil and further crops can be grown it for fulfilling the demand for future generations.
What is the relationship between heat production and resistance as related to electricity?
Answer:
Heat produced is directly proportional to resistance
Explanation:
Heat produced is directly related to the resistance if resistance will be more then heat production will also be more
The heat in produced is given by [tex]H=i^2RT[/tex], here i is current, Ris resistance and T is temperature.
From the relation we can see that heat is directly proportional to resistance so if we increase the resistance then heat produced also increase and if decrease the resistance heat produced decreases.
What is evolution and how is natural selection related?
Answer:
Natural selection leads to evolutionary change
Explanation:
Natural selection is a process by which the species adapt to their environment. Thus individuals have a better chance of survival and evolution and transfer their traits to offsprings. As the process of evolution cannot take place without genetic mutation or diversification of genetic buildup. The occurrence of repeatedly branching events take place in which new species splits from a common ancestor producing a multi-level tree. For example, in the event of climate change, those species capable of tolerating the temperature will not die as compared to those which are not capable of tolerating and thus will not reproduce. If the same process is repeated over millions of years of the time the population will get adapted to their new climate and develop genes that combat these drastic changes.The angular separation in degrees of two objects is(physical separation times 360 degrees/2 pi distance) if an individual was observing our solar system from Castor at a distance of 9.5 light years What angular resolution in arc seconds is needed to resolve the Sun-Earth system as distinct points of light
Answer:
[tex]\alpha = (3433\times 10^{-4})"[/tex]
Explanation:
given data:
distance between our solar system & castor is d 9.5 light year
we knwo that
[tex]1 \ light\ year =9.46\times 10^{12} km[/tex]
so [tex]d = 8.988\times 10^13 km[/tex]
distance between sun and earth is [tex]149.6\ million\ km = 149.6\times 10^6 km[/tex]
let angular resolution be[tex] \alpha[/tex]
by angular resolution formula
[tex]\alpha = \frac{s}{2\pi d} 360\ degree[/tex]
[tex]= \frac{149.6\times 10^6}{2\pi \times 8.98\times 10^{13}} \times360[/tex]
[tex] = 953.65\times 10^{-7}[/tex]
[tex] = 95.365 \times 10^{-6}[/tex]
now [tex]= 95.365 \times 10^{-6} = = 95.365 \times 10^{-6} \times \frac{60'}{1^o} \times \frac{60"}{1'}[/tex]
[tex]\alpha = (3433\times 10^{-4})"[/tex]
Does weathering of carbonates produce the same effect on atmospheric CO2as weathering of silicates? Explain your answer.
Answer:
Explained
Explanation:
The weathering of carbonate rocks or minerals, produce different acids as well as water. Some acids are hydrochloric acid, carbonic acid also bicarbonate. Again they break down from the element to produce CO2 into the atmosphere.
The main source for the generation of atmospheric CO2 is from the carbonates on the earth. But weathering of silicate does not liberate much CO2 than carbonate. The carbonation is more effective in weathering than silicate. Most of alkali metal like sodium, potassium, calcium and magnesium undergo the process of carbonation. Silicate minerals contribution to atmospheric CO2 is very less.
Question 2 Multiple Choice Worth 1 points) Which of the following is an example of how a water system is contaminated by non-point source pollution? Hikers toss food packaging into a mountain stream. Chemicals from batteries in a landfill leach into the groundwater supply. Several inches of acid rain fall over a lake. An oil pipeline bursts along the ocean floor. Fertilizers applied to a crop field run off the soil and into a river.
Answer:
One example of how a water system is contaminated by non-point source pollution is Several inches of acid rain fall over a lake.
Explanation:
Examples of non-point source pollution are mostly associated to rainfall or even snow melt. All the other alternatives in this question are examples of point source pollution. They all come from direct sources. The rainfall, however, is a diffuse form of pollution since it is spread throughout the lake.
3. Which of the following only happens within the arctic or antarctic circle?
A. The Sun reaches the zenith
B. The Sun rises in the west and sets in the east
C. The Sun does not cross the meridian
D. The Sun is up for 24 hours at a time
Answer:
C. The Sun does not cross the meridian, which is an imaginary line.
Explanation:
As all Meridien converges at the north and south poles, as there are no longitude or meridian lines running at this place so the sun continues to remain suspended at the same place throughout the day. As the solar noon is at other places on the earth and not at the poles of arctic and antarctic. Thus the sun does not go up or down this meridian. Rather its altitude in the sky constantly increases in winters, and sping and decreases in summers. All of this takes place due to the rotation of the planet on its axis. The tilt in motion creates an inclination for the sun rays falling on earth.Final answer:
The correct answer is D. The Sun is up for 24 hours at a time.
Explanation:
The Arctic and Antarctic Circles are significant because within these regions, polar day and polar night phenomena occur. Specifically, north of the Arctic Circle and south of the Antarctic Circle, the sun does not set for a full 24-hour period around the time of the summer solstice, resulting in what is called the "midnight sun". Conversely, during the winter solstice, these regions experience a 24-hour period without sunlight, known as the "polar night". This phenomenon does not occur anywhere outside of the polar circles. The sun never reaches the zenith, which only occurs up to 23.5 degrees from the equator (in the Tropics), and it never rises in the west and sets in the east nor does it fail to cross the meridian in a regular diurnal cycle outside of these unique polar day or night conditions.
how are the products and resources we consume actually produced?
fquestion from Environmental Science a study of interrelationships
Answer:
Product and resources are dependent on the environment such as fish , vegetables and milk.
Explanation:
As today's consumption pattern is determined by the environmental resource base as the real issue is not the type of consumption but the nature of consumption itself. About 85% of paper products that we consume comes from the natural resource on land. Similarly, many experts predict that the population will decrease at some point in time due to the resource that consumed are already reached its full capacity. Changes in consumption patterns have a direct bearing on the growing demands of people in various parts of the world. Resources and products that are manufactured from the raw form to finished from a that includes the carbon content and their daily consumption leads to overconsumption of resource.Answer:
Today, the production of goods, resources and services takes place through production chains, where 3 clearly differentiated productive sectors are identified:
1- the primary sector is in charge of the production of raw materials, through their generation and extraction from the natural environment to be used for the production of products or direct consumption by society. Example of primary activities can be agriculture or mining.
2- the secondary sector is the one that transports and processes the raw materials, finalizing the transformation of the raw material into a new product that satisfies a particular social need. Industrial activity is a secondary activity, which modifies these raw materials by launching processed products onto the market.
3- Lastly, the tertiary sector is in charge of marketing the processed and / or natural products directly for human consumption, that is, they bring goods and services closer to consumers. A clear example of tertiary activity is that of supermarkets or advertisers.
Two tectonic plates are diverging along a Mid-Oceanic Ridge. Which of the following features would NOT be found along that type of plate boundary?
a. Shallow earthquakes
b. Strong, deep earthquakes
c. Rifting and Normal Faulting
d. Symmetrical "stripes" of positive and negative magnetism parallel to the ridge
e. New crust being created directly from the mantle
f. Transform boundaries perpendicular to the ridge
g. Fissure volcanoes
Answer:
In a Mid-Ocean Ridge we are not going to find Strong, deep earthquakes
Explanation:
A Mid-Ocean Ridge is produced by divergence between plates, what generates a rift zone with normal faults; this kind of faluts are the result of tensional stress, that makes blocks to fall. When blocks are falling, they can produce some shallow earthquakes.
As plates are separating, there is growing a space between them and this allows magma to arrive to the surface, creating fissure volcanoes that are being part of the new crust that is being created. When rocks get cold, their magnetic minerals get oriented to the magnetic north, for that reason, as magma (next rocks) is being desposited at both sides of the ridge, we can find symmetrical stripes of positive and negative magnetism parallel to the ridge.
When ridges break up because of stress differences in the different segmentes, transform boundaries appear to conect all the ridge. On transform boundaries the displacement is horizontal, for that reason the are perpendicular to the divergent boundaries.
The Strong and deep earthquakes are not going to find under Mid-Ocean Ridge.
What is a Mid-Oceanic Ridge?A mid-ocean ridge refers to a seafloor mountain system which is constituted by plate tectonics.
It has an extent of about 2,600 meters and arises about 2,000 meters preceding the deepest percentage of an ocean basin. This dimension is where seafloor dispersive takes place along a different plate boundary.
It is created by separation between plates, which creates an opening zone with average faults. This kind of faults are the outcome of tension stress, that makes blocks to fall. They can produce some shallow earthquakes, when blocks are gone down,
There is growing a space between them and this allows magma to arrive to the surface, As plates are separating. And creates fissure volcanoes that are being portion of the new layer that is being created.
When rocks get cold, we find symmetrical stripes of positive and negative attraction parallel to the ridge and New crust being created directly from the mantle.
Therefore, option A is correct.

2-1. Point A is at elevation 2690 feet and is located 520 feet due north of point B which is at elevation 2220 feet. Point C is at elevation 2340 feet and is located 250 feet N35°E of point B. What are the strike and dip of a unit whose upper surface was observed at each of these points?
The strike of the unit is 270° (due west) and the dip is 43° to the south.
To determine the strike and dip of the unit, we can follow these steps:
Calculate the elevation differences:
Elevation difference between A and B: 2690 ft - 2220 ft = 470 ft
Elevation difference between C and B: 2340 ft - 2220 ft = 120 ft
Determine the horizontal distances:
Distance between A and B: 520 ft (already given)
Distance between C and B: Project the 250 ft line in the N35E direction onto a line due east of B (since the strike is perpendicular to the dip direction). Using the cosine rule, we get:
BC^2 = AB^2 + AC^2 - 2 * AB * AC * cos(N35E)
BC^2 = 520^2 + 250^2 - 2 * 520 * 250 * cos(35°)
BC^2 ≈ 302,000
BC ≈ √302,000 ≈ 550 ft
Calculate the dip and dip direction:
Dip angle = tan^-1((elevation difference between A and B) / (horizontal distance between A and B))
Dip angle = tan^-1(470 ft / 520 ft) ≈ 43°
Dip direction: Since point A is north of B, the dip direction is due south (180°).
Calculate the strike:
Strike = dip direction + 90°
Strike = 180° + 90° = 270° (due west)
If you have a square meter of soil with one plant and the plant photosynthesizes 2000 g of carbon per year and respires 1000 grams of carbon per year, what is the primary productivity of the square meter of soil?
Answer:
Primary productivity = 1000 gm/year/sq. meter
Explanation:
Primary productivity is defined as the difference betweeen main gross manufacturing and breathing energy. For the herbivorous, this is the energy available.
It is expressed as "gm/year/sq. meter" = gm/yr/m^2
or "kcal/year/sq. meter" = k cal/year/m^2
In the present case,
Gross primary production = 2000 gm/yr/m^2
Used for respiration purpose = 1000 gm/yr/m^2
So, Primary productivity = (2000 - 1000) gm/year/sq. meter
Primary productivity = 1000 gm/year/sq. meter
What is meant by the half-life of an unstable element?
Answer:
Half-life is defined as the time required by an unstable element to reduce half of its original value. All unstable elements have a decay rate and this half-life differs from element to element. These unstable elements are known as radioactive elements. It continuously decays until it becomes a stable one. These elements when decays release radiations which are harmful to lives.
This half-life plays an important role in the determination of the age of a rock or fossils. It is used in various types of radiometric dating methods.
For example, the half-life of Carbon-14 is approximately 5700 years and the half-life of Uranium-238 is 4.5 billion years.

5. How do the number of miles between longitude lines at the equator compare to the same lines near the poles?
Answer:
Explanation given under.
Explanation:
A map is a two-dimensional representation of the earth and its features on the globe so, to represent this, the latitude and longitudes are imaginary lines that separate the northern and southern ends of the earth being divided the Geographic equator at 0 degrees. These alt longs create a type of grid that gives to the coordinate system of the earth. Like the circle, the latitude and longitudes are measured in degrees, minutes and seconds. The equator being in 360 degrees, the longitude values ranging from 180 degrees W to 180 E. As all longitudinal lines are equal at all places, they always cover the same distance as 60 miles. In contrast, the degrees of Latitude vary as near equator the degree of latitude is 60 miles but as you approach the poles the distance becomes zero. The range of latitude then is -90 (S) to +90 (N) degrees i.e tropic of cancer 23.5N, tropic of Capricorn 23.5S, and the Arctic and Antarctic circles at 66.5 N, S.Which is true?

Answer:
E. the troposphere has a homogenous composition of all gasses and vapors including water.
Explanation:
The troposphere being a region of mixing is the homogenous composition of gases and water vapor that can be found in abundance in this layer above the surface of the earth. It is the stage for 99% of all the weather phenomenon and is well defined from the equator to poles. It is less dense near the equator and denser near the poles. About 75 % of the atmosphere is found below this layer above which lies the tropopause where the mixing stops and no changes in temperature at this layer. The layer extends from 0 to 20 kilometers in height. Apart from this dust particles are also found in this layer of the atmosphere.name the the leewards island

A surface of erosion on metamorphic or igneous rocks below sedimentary rocks is a(n): OA) nonconformity. OB) disconformity. OC) angular unconformity. OD) anticonformity. OE) none of the above
Answer:
Nonconformity
Explanation:
There are four different types of unconformity
Nonconformity is when there is an erosional surface on a metamorphic or igneous rock and we find sedimentary rocks (layers) over them
Disconformity is between sedimentary rocks that are divided by a surface of erosion and the have the same attitude
Angular unconformity is also between sedimentary rocks divided by an erosional surface, the difference here is that the have different attitude
Paraconformity Between sedimentary rocks without erosional surface and same attitude, the explanation is that there was a period withput deposition and without erosion

Question 4(Multiple Choice Worth 3 points) Which of the following formed at a divergent boundary? Marianas Trench Mid-Atlantic Ridge San Andreas fault The Hawaiian Islands The Himalayas
Answer:
Mid-Atlantic Ridge
Explanation:
It's here that the two oceanic crust split up an leads to the rising of magma or lava from the seafloor and thus this is called a divergent boundary and it leads to the creation of a new crust a new layer of rocks at the strata. Mid Atlantic ridges are existing since the creation of the earth and are a fundamental aspect of the formation of the plats on the surface of the earth. The upwelling of lava from the volcanic eruptions and earthquakes is result of the mantle plumes produced due to the this divergent boundary. Mid Atlantic ridges, thus account for the entire chain of the earth's surface features like mountain ridges, trenches, and deep-sea bottoms. Source of the convergence and other faults.Explain the positive and negative effects of globalization on environment?

Question 19 Which variable gas plays a major role in the formation of a) Nitrogen b) Oxygen c) Carbon Dioxide d) Water Vapor
Answer:
c) Carbon Dioxide
Explanation:
The majority of the variable gases are carbon dioxide, Water, Oxygen and Nitrogen all these one of the most for the existence of life on earth but out of these most variable gas found in the atmosphere is carbon dioxide. Found in all sorts of places and is a compound on the greenhouse gas it has existed on earth for thousands of years long. It is a major contributor to the balancing of the energy and heat budget of the planet. Apart from this carbon is needed as a driver of energy in the atmosphere as it absorbs heat and radiated it in the form of light and needed by the plants for carrying out their processes.Question 5: For a planet in an elliptical orbit to "sweep out equal areas in equal amounts of it", it must... a) move slowest when near the Sun. b) move fastest when near the Sun. c) move at the same speed at all times. d) have a perfectly circular orbit.
Answer:
Option (B)
Explanation:
According to the Kepler's 2nd law regarding the planetary motion, as the planets moves in an elliptical path, orbiting around the sun, and the line joining both the sun and planet forms an equal amount of area in equal amount of time. This equal area in equal time is maintained by the faster speed of the planet near the sun (Perihelion) and slower speed of the planet at a distance away from the sun (Aphelion).
Thus, the correct answer is option (B).
The correct answer is (b) the planet must move fastest when it is near the Sun, as described by Kepler's equal-area law, which is part of his laws of planetary motion.
For a planet in an elliptical orbit to "sweep out equal areas in equal amounts of time," it must move fastest when near the Sun. This is known as Kepler's equal-area law, which is one of the laws that describe planetary motion. According to this law, the line connecting a planet to the Sun sweeps out equal areas during equal intervals of time, meaning that the planet travels faster when it is closer to the Sun in its elliptical orbit. This occurs because the gravitational pull is stronger when the planet is closer to the Sun, which accelerates the planet and increases its orbital speed. Therefore, the correct answer to the question is: b) move fastest when near the Sun.

Background is golden, representing God’s presence
c.
Composition is symmetrical
d.
Faces are generic
Answer:
a. Mary shows physicality
Explanation:
The innovative work done by Giotto is the presence of human figure and its relationship with the outer world .
The options b , c , d shows the traditional methods of painting like background is golden and there is no symmetry because Mary and child is larger in shape with respect to the angels .
Faces shown can be generic or it might not be .
Hence , the most appropriate answer is ( a ) .
Final answer:
Giotto's innovative element in Madonna Ognissanti was the use of an architectural and earthly setting to introduce depth and space, presenting the figures in a relateable and naturalistic manner.
Explanation:
The artistic innovation in the painting Madonna Ognissanti by Giotto that the question refers to is the use of an earthly setting and architectural elements to create a sense of space and depth, a departure from the flat gold background representing divine space typical of the time. Unlike his predecessors Cimabue and Duccio, Giotto introduced an architectural space for each of the subjects, such as the Madonna and the angel, adding to the illusionism present within these cycles. This contributes to the representation of Mary as a figure relatable on earth and presents a significant leap toward a more naturalistic and humanized portrayal in art. The correct answer to the question would be letter a, expressing Mary's physicality and humanity.
How would changes in the average temperature of the troposphere affect the altitude of the tropopause?
Answer:
As the temperature inversion occurs around this zone
Explanation:
Troposphere The lowest layer of atmosphere found on the surface of the earth from 0 to 30 kilometers it's wider in equator i.e 18 km and narrows at poles till 6-8 km only. At this layer, 90 % of all convective activity takes place, turbulence and cloud formation like stuff. Consists of 80% of water vapor and dust particles. In troposphere the temperature in the air decrease with gain in height with a height of an overall positive lapse rate of 6.5 degrees C / km. The onset of tropopause the region where mixing stops and temperature remains constant and extends up to a layer of 11 to 20 kilometers. However, lapse rate variation sometimes occurs in between this sphere and affects the altitude of the tropopause. The seasonal effect is strongest at the mid-latitudes and varies with changes latitudes.What are the mechanisms whereby a) plants affect weathering, and b) weathering affects atmospheric CO2concentrations? Write the major equations involved for the most important reactions.
Answer:
Explained below.
Explanation:
Plants roots break the rocks and soil from the bottom and derive up nutrient form the steam to leaves and its due to this factor the planet are considered as an agent in biological weathering like animals that bring up the soil particles and displace the soil matter and expose the rocks at greater depths. Weathering is directly affected by the atmospheric conditions such as the concentration of atmospheric pollutants by the human-induced factors and the weathering created due to the erosion of base rocks and this happens in chemical weathering phases.An equation is given for reference
2(HCl) + CaCO3 ---> Ca+2 +2Cl- + H2O + CO2.
Here chemical distinction and breakdown of elements on earth surface take place.Which of the following is supposed to be the basis for putting organisms in the same taxon (zoological or phylogenetic category)?
a. all phenotypic traits
b. homologous traits
c. analogus traits
d. only similarities that have evolved since the time of their common ancestor
Answer: d. only similarities that have evolved since the time of their common ancestor.
Explanation:
A taxon is a group of one or more members of the organisms that forms a single unit based upon common characteristics they acquire through inheritance or they acquire from their environment.
The taxon can include the shared characteristics that suggests that all living beings are descendants of the common ancestor. They exhibit similarities in the genetic make up that is DNA. It is expressed by the genes through transcription and translation.
