Question

List 4 human activities that contribute to erosion and deposition. Explain how these activities may be modified to reduce erosion.

Answer 1

Answer:

Human activities cause erosion in a number of ways across the globe. Research has shown that humans are responsible for more erosion than natural processes.

1. Deforestation - it drastically causes an increase in the erosion rates as plant roots hold soil tightly that prevent erosion due to wind and water but cutting trees increases it. Plantation reduces erosions.

2. Agricultural practices have an impact on erosion rate. This promotes the likelihood of erosion, as the soil can be transported more easily due to wind and water.

3. Growing monocultures - one type of crop leads to an increase in erosion as nutrition and components of soil are drastically reduced. r

4. chemical fertilizers in agriculture can also increase soil erosion, as these chemicals damage, the flora, and fauna that live in the soil.

5. Mining/walking or biking and other practices can also contribute to erosion gradually over time. Mining exposed soil during this process.
