The correct answer is letter <span>d. none of the above. The choices presented are possible cause of soil erosion. Soil erosion happens when a big boulder of rocks and soils coming from a mountain slide down because of external forces just like water (specifically during heavy rains), gravity, and as well as burrowing animals.</span>
These chemical processes need water , and occur more rapidly at the higher temperature ,so warm ,damp climates are best.
