उत्तर
Yes, weathering is an essential pre-requisite in the formation of soils. Weathering is action of elements of weather and climate over earth materials. There are a number of processes within weathering which act either individually or together to affect the earth materials in order to reduce them to fragmental state. Weathering is mechanical disintegration and chemical decomposition of rocks through the actions of various elements of weather and climate.
Weathering is an important process in the formation of soils. When rocks undergo weathering, rocks start to break up and take form of soil gradually.
