Question

Uniform soil erosion by running water is

• A. Gully erosion
• B. Rill erosion
• C. Riparian erosion
• D. Sheet erosion

Answer 1

The correct option is D Sheet erosion

Soil erosion is removal of top soil by agency of water (water erosion) and wind (wind erosion). Soil erosion is of two types- natural and anthropogenic.

Natural or geological erosion is extremely slow removal of top soil due to rain water or wind.

Anthropogenic soil erosion is caused by removal of plant cover through over grazing, litter collection, tree felling, leaving the soil unprotected during agricultural operations.

Sheet erosion means removal of extremely thin layer or sheet of soil. It is caused by detachment of soil particles by raindrop impact and their removal downslope by water flowing overland as a sheet (instead of flowing in definite channels or rills).
