Answer 1

The correct option is A Soil 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.
