Soil is a thin layer of material covering the earth's surface that forms when rocks crumble. It consists mainly of mineral particles, organic materials, air, water and living organisms, all slowly but constantly interacting with each other. In short, soil is a mixture of minerals, dead and living organisms (organic materials), air and water. These four components interact with each other in amazing ways, making soil one of the most dynamic and important natural resources on our planet.
Erosion and deposition are responsible for many landforms. Erosion is the transport of sediments. Agents of erosion include flowing water, waves, wind, ice, or gravity. Eroded material is eventually dropped somewhere else. This is called deposition.Man uses soil in many ways. Soil provides many important services to both people and the planet. Soil puts food on our plates, cleans water, protects us from floods and fights drought. It also plays a key role in combating climate change by sequestering and storing huge amounts of carbon. There is no food security without healthy soil.

in a forested watershed, if you remove (or log) the trees, what happens to evapotranspiration and to runoff?
If the trees are removed then evaporation drops and stream flow increases. It will impact on the streams in the watershed.
In the forest watershed, trees and forests absorb and use tremendous amounts of water for growth. A single mature oak tree can consume over 40,000 gallons of water in a year. In Pennsylvania forests, an average of 24 inches of the annual 40 inches of rainfall is taken up by trees through evapotranspiration. Evapotranspiration is defined as the movement of water from the ground through the tree and leaves, evaporating back into the environment that also serves to cool and modify surrounding summer temperatures. If the forest is removed or harvested, evaporation drops to 14 inches and stream flow increases to receive 26 inches of the annual 40 inches of precipitation. So, just the removal of forests can have an impact on streams in the watershed.

Determine the acceleration of earth due to its motion around the sun. Assume the earth's orbit to be circular with a radius of.
The acceleration of the earth around the sun is 5.95 103 m/s2, which is the definition of centripetal acceleration.
Definition of Centripetal AccelerationA motion feature that applies to objects moving in a circular motion is called centripetal acceleration. It is referred to as moving with centripetal acceleration when an item moves in a circle including its acceleration vector pointing inside the direction of the circle's center.
The following is the result for the acceleration of the earth around the sun according to the definition of centripetal acceleration:
a = 5.95 10⁻³ m / s²
A body accelerates centripetally when all of its energy is put toward changing the direction of its velocity while maintaining a constant value for its modulus.
a= [tex]\frac{v^{2} }{r}[/tex]
They show that the circular orbit's radius is r = 1.5 10⁸ km = 1.5 10¹¹m.
Since the speed is constant in a circular motion, we may use the uniform motion relation to calculate the speed.
[tex]v = \frac{L}{t}[/tex]
The orbital circle has the following radius:
L = 2π r
The period is the amount of time required for an orbit to complete.
v = 2πr / t
The Earth's orbit has a year-long period.
T = 3.154 10⁷ s
Now let's determine the velocity.
v = 2 pi X 1.5 X [tex]10^{11}[/tex] / 3.154 10⁷
v = 2.988 10⁴ m / s
We can now determine the acceleration.
a= [tex]\frac{(2.988 X 10^{4} )}{1.5 X 10^{11} } ^{2}[/tex]
a = 5.95 10⁻³ m / s²
Using the definition of centripetal acceleration as a guide, we can conclude that the acceleration of the earth's rotation around the sun is as follows:

cold weather , water that drips from roofs becomes icicles ,therefore what type of phase change is this
Answer:
The formation of icicles from water that drips from roofs in cold weather is an example of the phase change from a liquid to a solid.
Explanation:
The formation of icicles from water that drips from roofs in cold weather is an example of the phase change from a liquid to a solid. Water is a substance that exists in three main states or phases: solid (ice), liquid (water), and gas (water vapor). When water is exposed to cold temperatures, the kinetic energy of its molecules decreases, and the water becomes less able to move freely. As a result, the water molecules begin to slow down and form a more organized, crystalline structure, and the water changes from a liquid to a solid, forming icicles.
The process of water changing from a liquid to a solid is known as freezing, and it is the opposite of the phase change from a solid to a liquid, which is called melting. When water freezes, it releases latent heat, which is the energy that is stored in the water molecules as they change from a liquid to a solid state. This release of latent heat can help to keep the surrounding air warm, and it can prevent the temperature from dropping too low, which can be beneficial for plants and animals in cold climates.
Overall, the formation of icicles from water that drips from roofs in cold weather is an example of the phase change from a liquid to a solid, and it is an important part of the Earth's natural processes and cycles.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.
What is Probability ?An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The likelihood that an event will occur increases with its probability.
A straightforward illustration is tossing a fair (impartial) coin. Since there are no other conceivable outcomes and the coin is fair, the chance of both "heads" and "tails" is equal to half. Since there are no other possible outcomes, the probability of either "heads" or "tails" is equal to half.
In all there are 6+6+6 = 18 socks in drawer .

In the process of frost wedging, how does ice cause cracks in rocks to become larger?.
This type of mechanical weathering breaks apart rocks and other materials using the expansion of freezing water. In the process of frost wedging, Ice expands when it freezes, pushing the rocks apart.
Ice wedging makes many rocks break. This alludes to the continued freezing and liquefying of water inside little hole in the stone surface. This extension and compression is likewise a significant reason for potholes in roads. Water saturates breaks in the stones, and, as the temperature decreases underneath freezing, the water grows as ice in the breaks. The extension applies colossal strain on the encompassing stone and behaves like a wedge, making breaks more extensive. After continued freezing and defrosting of water, the stone falls to pieces.
