Question

why is a arid soil easily eroded than moist soil?

Answer 1

Answer:

Owing to the presence of dry climate and high temperature, evaporation occurs at a faster rate. This soil lacks humus and moisture.

Answer 2

Because of the scarcity of vegetation that can reduce air movements, arid regions typically are windy. Winds remove the moist air around the plants and soil and, as a result, increase evapotranspiration. Depletion of vegetative cover on the land is the basic cause of soil erosion by wind.
