Question

why does laterite soil undergoes leaching?

Answer 1

Laterite soils undergoes leaching because they were formed in wet tropical conditions.

Answer 2

ANSWER:

Laterite soils undergoes leaching since they were formed in wet and hot tropical conditions.

EXPLANATION:

   Laterite soil is a rock type abundant in aluminium and iron and is formed in wet and hot tropical areas. Leaching is a procedure wherein the soil nutrients (colloids and soluble substances)permeate down the soil because of heavy rainfall.

   The lost materials are taken downwards i.e. eluviated and are usually re-deposited i.e. (illuviated) in the bottom layer. This transport leads to an open, porous topmost layer and a compact, dense bottom layer. The leaching rate increases with the rainfall amount, higher temperatures, and the eradication of protective vegetation.

   Laterite soil is made in regions of heavy rainfall where the vital nutrients of the soil permeate down the soil. Secondly, the laterite soil is the residual or remainder soil formed by extensive leaching.
