Answer:
Soil erosion is much accelerated in hilly and mountainous regions.
Soil erosion
Soil erosion is the natural process in which the topsoil of a field is carried away by physical sources such as wind and water.
- The wearing away of the topsoil is a normal phenomenon, but human activities have enhanced it.
- It is normally caused by the removal of vegetation or some other practice that causes the field to become dry.
- Soil erosion is caused by farming, grazing, mining, building, and recreational activities, to name a few.
- Soil erosion has far-reaching consequences that go beyond land loss. It has resulted in a significant rise in waste and sedimentation in rivers, clogging water sources and causing a decrease in aquatic organism populations.
- Floods occur when degraded lands lose their ability to retain water.
