What is known as exfoliation?

उत्तर
Exfoliation is the process in which outer layers of rock peel off due to temperature changes. In regions with high daytime temperatures and cool nighttime temperatures, the repeated expansion and contraction of the rock surface causes it to crack and break into thin layers or sheets. This is a form of mechanical weathering, often seen in rocks like granite.
