You went to the Rann of Kutch for the Rann Utsav, which is celebrated annually in Gujarat. On your way, which kind of weathering did you notice? What could be its cause/causes?

On my way to the Rann of Kutch, I noticed mechanical (physical) weathering of rocks.

The Rann of Kutch has a hot desert climate, with very high daytime temperatures and cool nights. The large daily temperature range causes rocks to expand during the day and contract at night. Repeated expansion and contraction lead to block disintegration.

Since most rocks are poor conductors of heat, only their outer layers are affected. Repeated heating and cooling cause these layers to peel off, a process known as exfoliation.
