Study Notes
Soil Erosion
- Human activities that can lead to an increase in soil erosion include:
- Deforestation
- Overgrazing
- Construction
- Mining
- Plants play a crucial role in preventing soil erosion by:
- Holding soil in place with their roots
- Providing a protective cover of vegetation
- Stabilizing the soil
- Bare or exposed soil is especially vulnerable to erosion because:
- It lacks a protective cover of vegetation
- It is more susceptible to water and wind erosion
- The soil is not held in place by roots
- Actions that can speed up erosion include:
- Removing vegetation
- Compacting the soil
- Increasing the flow of water
- Conserving and protecting soil for future generations is important because:
- Soil is a non-renewable resource
- It takes centuries to form just a few inches of soil
- Soil is essential for food production and ecosystem health
- Human activities that can leave the soil exposed and speed up erosion include:
- Deforestation
- Overgrazing
- Construction
- Mining
- The main reason why soil is especially vulnerable to erosion when it is bare or exposed is:
- Lack of a protective cover of vegetation
- Actions that can lead to an increase in erosion include:
