1. How do animals cause erosion? 2. How do human activities affect the rate of erosion?
Answer (1)
Animals contribute to erosion through various actions like grazing, burrowing, and trampling, which expose soil and increase its susceptibility to wind and water erosion. Overgrazing, where too many animals graze in a single area, can remove plant cover and destabilize the soil. Burrowing animals disrupt the soil structure and can remove sediment. Human activities significantly increase the rate of erosion by disrupting natural processes that stabilize soil and increasing exposure to erosive forces like wind and water. This is mainly due to activities like deforestation, agricultural practices, and construction.
