The correct answer is - deforestation.
Deforestation is a huge issue when it comes to soil erosion. When there's thicker vegetation the soil is in place and the erosion is minimal. This is due to the root systems of the trees, bushes, grashes, that are making a natural net inside the soil that holds it in place and doesn't allow the soil to be moved away and thus erosion to take place. But when we have a deforested landscape than the situation is the total opposite. The soil is left on its own and it doesn't have any protection from the root systems to keep in place, so with every rain it is eroding slowly and occasionally quickly when there's heavy rainfall. Most of the erosion takes place on the steeper parts.
Impact craters are rare on the surface of the earth and plentiful on the moon its because our atmosphere burns up more meteoroids before they meet the surface. Another reason is that the surface of the earth is continually active and erases the marks of crater overtime. There are also many other large craters being found in Canada, Australia and Africa.
Answer: The answer is D: It increases in magnitude as amount of damage increases.
