Question

Explain the following causes. 1. Water run offs 2. Wind 3. Man’s activity 4. How serious is soil erosion a Problem?

Answer 1

Answer:

1) The increasing amount of fresh water in the ocean is causing drastic changes in the saltwater

habitats. Runoff occurs when there is more water than land can absorb. Glaciers, snow, and rain all contribute to this natural runoff. Runoff also occurs naturally as soil is eroded and carried to various bodies of water.

2) Air that is moving across the surface of the earth OR the breath that you need for doing exercise

or playing a musical instrument.

3)Human activity - something that people do or cause to happen. human action, act, deed. event - something that happens at a given place and time. action - something done (usually as opposed to something said); "there were stories of murders and other unnatural actions"

4)The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

Answer 2

Answer:

1) Water will run off because of our daily wastage of water. Today many people think that it is not my problem because they have water 24hours in a day .If we waste water today than for this we pay in tomorrow or our generation and we have to know that if we don't care about this than the whole earth will be destroy because water is a thing that can make anything non reactive and is necessary for the digestion of food. So don't waste water because it will run offs.
