Explain why climate is considered to be the most influential control of soil formation.
Answer:
Explained below
Explanation:
Climate plays a very vital role in soil formation. Climate influences the temperature and moisture of a particular geographical area. Now temperature and moisture influence speed of chemical reactions, which in turn helps control how fast rock weather and dead organism decompose. Soil develop faster in warm, moist climate and slow ion cold and arid ones. Rainfall also has an important role to play in soil formation.
Which of the following has been most clearly associated with climate change? Extreme cold in Europe. Extreme dry events in the tropics. Extreme snow in North America. Extreme precipitation in the southern hemisphere.
Answer:
Extreme precipitation In the southern hemisphere
Explanation:
Many scientists argue that climate change has led to Extreme dry events in the tropics.
The tropical areas of the planet:
Are meant to experience rain all year round Have recently seen unusual dry spellsThe unusual dry spells experienced in the tropics can point to climate change because it means that the climate of the tropics are changing from what they originally were to something more dry.
In conclusion, evidence of climate change is the dryness in the tropics.

2. If both the mass and radius of the earth, each decreases by 50%, the acceleration due to gravity would (a) remain same (b) decrease by 50% (c) decrease by 100% (d) increase by 100%
Answer:
(d) increase by 100%
Explanation:
[tex]m_{i}[/tex] = initial mass of earth = m
[tex]m_{f}[/tex] = final mass of earth = (0.5) m
[tex]R_{i}[/tex] = initial radius of earth = R
[tex]R_{f}[/tex] = final radius of earth = (0.5) R
[tex]g_{i}[/tex] = initial acceleration due to gravity of earth = g
[tex]g_{f}[/tex] = final acceleration due to gravity of earth
initial acceleration due to gravity of earth is given as
[tex]g_{i} = \frac{Gm_{i}}{R_{i}^{2}}[/tex] Eq-1
Final acceleration due to gravity of earth is given as
[tex]g_{f} = \frac{Gm_{f}}{R_{f}^{2}}[/tex] Eq-2
Dividing eq-1 by eq-2
[tex]\frac{g_{i}}{g_{f}} = \frac{m_{i}}{m_{f}}\frac{R_{f}^{2}}{R_{i}^{2}}[/tex]
inserting the values
[tex]\frac{g}{g_{f}} = \frac{m_{i}}{(0.5)m_{i}}\frac{(0.5)^{2}R_{i}^{2}}{R_{i}^{2}}[/tex]
[tex]g_{f}[/tex] = 2 g
So there is 100% increase
Why doesn’t radiometric dating of basalt on the ocean floor provide us with an absolute age for the planet earth?
Select one:
a. New oceanic crust is produced every day
b. Black smokers alter the rock so radiometric dating is ineffective
c. Spreading rates at mid-oceanic ridges are variable
d. Oceanic crust is recycled too frequently at subduction zones
e. Mid-oceanic ridges move over time
Answer:
Why doesn’t radiometric dating of basalt on the ocean floor provide us with an absolute age for the planet earth -
Oceanic crust is recycled too frequently at subduction zones,
Explanation:
The reason why radiometric dating of basalt don’t give the exact age of the sea floor because the oceanic crust is denser in nature and at the subduction zone this oceanic crust subducts under the light continental crust where it melts and thus recycling of oceanic crust takes place very frequently and hence it cannot be used for absolute dating of the oceanic crust and therefore the correct option is option ( d ) Oceanic crust is recycled too frequently at subduction zones .
Radiometric dating of basalt on the ocean floor cannot give an absolute age for Earth due to the continuous production of new oceanic crust and the recycling of crust at subduction zones. So, option a is correct.
The reason radiometric dating of basalt on the ocean floor does not provide an absolute age for the planet Earth is because that new oceanic crust is produced every day. This continuous generation of new crust makes it challenging to obtain a definitive age for the planet through radiometric dating of basalt in oceanic regions. Additionally, oceanic crust is recycled too frequently at subduction zones, further complicating the determination of Earth's absolute age using this method.
Answer the following:
1. A predatory wasp that feeds exclusively on herbivorous ants would be an example of a(n) _______ that is part of the _______ trophic level.
A) carnivore; third
B) herbivore; second
C) carnivore; second
D) omnivore; third
2. If herbivores eat 200 kg of plants, and the total plant biomass is 1,000 kg, the _______ efficiency is _______%.
A) assimilation; 80
B) consumption; 20
C) consumption; 80
D) assimilation; 20
3. Suppose two agents are introduced into soil: one that results in an increase in nitrification and another that results in an equal addition of denitrification. Compared to the soil before, the combination of equal amounts of nitrification and denitrification in the soil would result in a net increase in (hint â look at the reactants and the products)
A) NH4+
B) NO3â
C) N2O
1. A) carnivore; third
The trophic levels are divided by the manner in which the energy is produced and consumed among the living organisms. The first trophic level is occupied by the autotrophs, which are the organisms that are able to produce their own food. The second trophic level is occupied by the organisms that feed upon the autotrophs, thus they are the herbivores, as well as the omnivores in partial sense. In this case we will have the ants at the second level. The third trophic level is reserved for the organisms that feed upon the organisms of the second trophic level, thus they are predators. In this case, we will have the wasp in the third trophic level.
2. B) consumption; 20
If there are herbivores and plants, the plants account for 1,000 kg in biomass, and the herbivores eat 200 kg of them, then the consumption is 20% of the total biomass. This kind of a scenario is able to support the whole population of herbivores without any problem, as there is much more food than they need. It will only become a problem if the population of herbivores starts to grow exponentially, and they start to consume all of the food and even require more, the population will collapse.
3. C) N20
The processes and nitrification and denitrification are very common, both in nature, and because of the human activity. The human activity has actually increased this process significantly. The main product of the nitrification-denitrification is the N2O. It is a vital product for the nitrogen cycle, and it is one that is increasing the atmospheric temperature, thus too much of it is not of best interest for anyone.

Which of these statements or sentences best describe "The Migratory Bird Rule". Select one a. was promulgated by the EPA. b. prohibits hunters from shooting birds that migrate across states. c. was struck down by the Supreme Court in the late 1990s or early 2000. d. allows bird watchers to sue persons who kill or poison birds.
Answer:
c. was struck down by the Supreme Court in the late 1990s or early 2000.
Explanation:
The correct answer is option B.The best statement describing 'The Migratory Bird Rule' is the prohibitive measure against hunters targeting migratory birds crossing state lines, guided by the Migratory Bird Treaty Act of 1918. The law is crucial for the conservation of over 800 bird species, but has faced recent challenges limiting its scope to only intentional harm.
The Migratory Bird Treaty Act (MBTA) is a cornerstone of wildlife conservation law in the United States, having been enacted in 1918 in conjunction with Canada to address the decline of bird species due to hunting pressures. The statement that best describes 'The Migratory Bird Rule' is the one that refers to the prohibition of hunters from shooting birds that migrate across state lines. This legislation makes it illegal to hunt, disturb, or kill over 800 protected migratory bird species, such as the northern cardinal or the American black vulture.The MBTA was originally established to halt the declines in bird populations by making it unlawful to bother or kill protected species or to trade their parts, a practice that was once quite common for their feathers. The act is notable for allowing regulated hunting under certain conditions but also for setting stringent protections against the deaths caused by industrial activities, such as those resulting from oil spills or mining operations. However, recent administrative revisions have focused on the 'incidental take' provision, which has now been interpreted to not apply unless intentional harm can be demonstrated, thus potentially weakening the principal protections of the MBTA.

Which of the following concepts from the Noel hypothesis describes why Africans were enslaved rather than other groups? A) competition hypothesis B) differential in power C)desirability of indentured servants D) religious servitude
Answer:
The correct option here is B) differential in power.
Explanation:
As per the Noel hypothesis Africans were chosen above other groups such as native Americans and other white groups because of differential in power . The whites had a more dominant position than the Africans, who were brought in to the country as cheap labor. According to this hypothesis if a couple of groups come together who were characterized by the features such as ethnocentrism, competition and differential in power , then this will lead to a racial stratification.
clues to the nature of the source area of sediment can be found in
Clues to the source area of sediment include its mineral composition, fossil content, and textural features such as sorting and rounding. These clues help determine the provenance, which is key for understanding geological history and past climates.
Clues to the nature of the source area of sediment can often be found by analyzing certain characteristics of the sediment itself. For example, the mineral composition, fossil content, and textural features such as sorting and rounding, can help scientists to determine the provenance of the sediment. This is essential for understanding the tectonic history, visualizing paleogeographic formations, and unraveling geological histories. Sedimentology is a specific tool used to investigate past environments and climates by examining the size, shape, texture, and composition of sediment deposits.
For instance, biotite grains found at the bottom of a lake could indicate that they originated from nearby metamorphic rocks or granites, depending on their ages and the geology of the area. Additionally, different environments of deposition are indicated by the characteristics of the sedimentary rocks formed. For example, a quartz sandstone with well-sorted and well-rounded grains suggests long-distance transportation by water, while a breccia with poorly sorted, angular limestone fragments indicates deposition closer to the source rock.

Which of the following is not an esxample of blogenic sediment? Select one: Θ a, microscopic skeletal fragments O b. abyssal clay O c. corals O d. biogenic ooze O e. organic plant remains t of 2.00
Answer:
abyssal clay is not an example of biogenic sediments .
Explanation:
Any sediment containing more than 30% of organic matter in it , is called as biogenic sediment or biogenic ooze.
The two most common types of biogenic oozes are calcareous and sileceous.
abyssal clays are the fine grained sediment particles that are settled in the deep ocean basins.
abyssal clay mostly consists of land derived eroded particles and have less than 30% of organic matter in them ,
Hence , abyssal clay is not an example of biogenic sediment.
Much of the early hydrogen and helium escaped the earth's atmosphere into space because ________. The earth's gravity was strong The earth's gravity was weak Solar winds were weak Solar winds were strong All of the above
Answer:
The most suitable answer to the given question out of the given options is:
The earth's gravity was weak
Explanation:
One of the reason to explain that much of the early helium and hydrogen escaped into space from the earth's atmosphere is because the escape velocity of helium and hydrogen is much higher than the critical escape velocity of earth.
Another reason is that Helium and Hydrogen are much lighter in weight and can't be pulled into the atmosphere by weak gravity of earth.
What happens to pressure, temperature and density with increasing depth inside the Earth? 1) there is no way of knowing 2) they are all variable, sometimes going up, sometimes going down 3) pressure and temperature go up continually, but density only increases in steps at the crust-mantle and mantle-core boundaries 4) they all increase
The correct answer is 4. They all increase.
Explanation
The earth is composed of different layers, from the inside to the outside they are the nucleus, the mantle, and the earth's crust.
The nucleus or deepest layer, is a sphere half liquid, half solid, of around 3200km of radius, and its temperature exceeds 6500 ° C, in the same way, the pressure is much greater than that of other layers. On the other hand, the mantle is the intermediate layer and the widest in the earth because it goes from 30km to 2900km, its temperature is relatively low to have close to 600 ° C and its pressure is around 140 pascals. Finally, the earth's crust is a solid layer that is found from the surface up to 70km deep, in it the pressure, temperature and density are lower than in the core and mantle zone. This shows in summary, the trend of density, temperature, and pressure increase with increasing depth inside the Earth. So, the correct answer is 4. They all increase.
Final answer:
Pressure and temperature inside the Earth increase continuously with depth, while density increases in distinct steps at major internal boundaries. These changes are due to the weight of overlying materials, residual heat, and compositional differences between the Earth's layers.
Explanation:
The question asks what happens to pressure, temperature, and density with increasing depth inside the Earth. The correct answer is that pressure and temperature increase continually as depth increases, while density only increases in steps at the crust-mantle and mantle-core boundaries. This pattern arises because the Earth is differentiated into layers, each with distinct physical properties. The pressure increases with depth due to the weight of the overlying layers, and the temperature also increases, making melting more likely at greater depths. However, increased pressure raises the melting temperature. Density increases discontinuously at major boundary layers due to compositional changes and the compression of materials at these boundaries.
Temperature rises with depth, influenced by residual heat from the Earth's formation and the decay of radioactive elements. Pressure also increases consistently due to the immense weight of overlying materials. Density changes are more complex; while it generally increases with depth due to compression, it does so in noticeable steps at the boundaries between the Earth's crust, mantle, and core, reflecting changes in material composition and phase.

cyclical changes in solar irradiance caused by increases and decreases in sunspot activity.
increases and decreases in atmospheric gases and aerosols, primarily caused by natural activity, such as volcanic eruptions and changes in net primary productivity.
tectonic changes in continental positions
Milankovitch cycles refer to changes in the Earth-Sun relationships caused by variations in the Earth's orbit, axial rotation, and axial tilt, affecting the climate and leading to cycles of ice ages and warm periods.
Explanation:Milankovitch cycles refer to changes in Earth-Sun relationships, which are specifically caused by variations in the Earth's orbit around the sun, axial rotation, and axial tilt. These changes lead to long-term alterations in the sunlight Earth receives, affecting climate over thousands of years. For example, the axial tilt changes over around 41,000 years from 22.1 to 24.5 degrees and back. When the tilt increases, summers get warmer and winters colder, contributing to the start and end of ice ages. However, they do not refer to topographic changes, solar irradiance changes due to sunspot activity, or changes in atmospheric gases and aerosols. The concept of Milankovitch cycles is primarily used in the field of paleoclimatology.

Milankovitch cycles refer to changes in Earth's relationships with the sun, including Earth's orbit, axial tilt, and axial rotation. These changes, derived from the theory developed by Milutin Milankovitch, result in long-term climate variations on Earth.
Explanation:The Milankovitch cycles primarily refer to the changes in Earth-Sun relationships that include Earth's rotation, axial tilt, and the shape of its orbit around the sun. Serbian engineer and mathematician Milutin Milankovitch developed this theory, which explains long-term climate changes on Earth. His theory is based on three parameters: Eccentricity, Obliquity, and Precession. Eccentricity is the variation in the shape of Earth's orbit from nearly circular to elliptical over about 100,000 years. Obliquity pertains to the change in axial tilt over around 41,000 years, and Precession refers to the gradual shift in the direction of Earth's axial rotation over roughly 26,000 years. Together, these parameters resulting in Milankovitch cycles are thought to be a significant driver of Earth's long-term climate variability.
