OBJECTIVE FORESTRY

Detailed explanation-1: -leaching, in geology, loss of soluble substances and colloids from the top layer of soil by percolating precipitation. The materials lost are carried downward (eluviated) and are generally redeposited (illuviated) in a lower layer. This transport results in a porous and open top layer and a dense, compact lower layer.

Detailed explanation-2: -Erosion is the normal mechanism by which, by exogenetic mechanisms such as wind or water flow, soil / rock is separated from the surface of the Earth, transported and deposited in other areas. By percolating water, leaching is the removal of soluble content from soil or other content.

Detailed explanation-3: -Soils most susceptible to erosion are those with the largest amount of medium (silt)-size particles. Clay and sandy soils are less prone to erosion. 4) Ground slope – its combined length, grade, and surface quality (rough or smooth) – affects erodibility.

Detailed explanation-4: -The correct option is C Laterite soil.
