The geological wearing down of land surfaces via wind, water, glaciers, or other agents is called____________________?
Show answer Hide answer
Answer: B. Soil erosion
Explanation
Soil erosion is the geological process involving the wearing down and displacement of topsoil. Natural agents like wind water and ice detach and transport soil particles away. Land degradation often accelerates when protective vegetation covers are removed. Sheet rill and gully erosion represent different stages of water-driven soil loss. Topsoil contains vital organic matter and nutrients necessary for plant growth. Soil conservation practices like contour plowing help mitigate destructive erosion rates.
Agricultural productivity declines severely when productive topsoil is lost to erosion. Environmental agencies implement watershed management projects to control sediment runoff. Global food security is threatened by ongoing accelerated soil erosion in farmlands. Seepage describes water leaking slowly through porous soil or rock structures. Soil contamination involves the presence of toxic chemicals rather than physical soil loss. All the above is incorrect because only soil erosion describes land surface wearing.
