A large area of land is cleared to build a new school. how does this affect the area.
A)it increases soil erosion
B)it decreases soil erosion
C)it increases groundwater
D)it decreases surface runoff
My answer is A
I disagree.
is the answer B
A) it increases soil erosion
When a large area of land is cleared to build a new school, it typically involves removing vegetation and trees. These are natural barriers that protect the soil from erosion caused by wind and water. Without the protective cover, the exposed soil is more susceptible to erosion.
To understand why this happens, we can look at the role of vegetation in preventing soil erosion. Plants roots help bind the soil together, providing stability and preventing it from being easily carried away. The above-ground parts of plants, such as leaves and stems, act as a natural barrier, reducing the force of wind and water on the soil surface.
By clearing the land, we remove these natural defenses against erosion. Rainwater, for example, can wash away the loose soil more easily without the presence of plants and their roots to hold it in place. Similarly, wind can blow away the top layer of soil, especially if there are no trees or other vegetation to act as a windbreak.
Therefore, the clearing of land to build a new school typically increases soil erosion in the area.
