Answer: B

Solution.

In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water.
When rain falls on soil without vegetational cover, rain water causes loss of surface soil or Top soil. Topsoil, which is high in organic matter, fertility and soil life, is relocated elsewhere "on-site" where it builds up over time or is carried "off-site" where it fills in drainage channels.
