Solution(By Examveda Team)
A weathering process in which layers of rocks peel off as expansion alternates with contraction, is known as Exfoliation. Rocks are generally poor conductors of heat. The effect of daily heating and cooling is confined to surface layers of the rock. The outer layer of rock is heated up and expands during the day while the inner layer of rock remains cool. The outer layers eventually peel off (like an onion skin), exposing the inner layers to the surface for further exfoliation.Related Questions on World Agriculture, Minerals and Industries
