I went to the Rann of Kutch for the Rann Utsav, which is celebrated annually in Gujarat. On my way, I noticed mechanical or physical weathering of rocks.
Rann of Kutch experiences desert type of climate i.e., very hot during the day and cold during the night. The sudden rise and fall of temperature causes expansion and contraction of rocks. The repeated action causes their breakdown. At night the temperature suddenly falls and during the day it rises suddenly. This leads to tension and splitting of rocks and block disintegration of rocks.
Most rocks are not good conductors of heat. The sudden contraction and expansion peels off the outer layer of the rock, which is known as exfoliation.
