Best Answer

In arid or dry climates like deserts, the sun heats up rocks in the day. So the rock expands. At night it cools down so the rock contracts. The constant expanding and contracting weakens the rock and over time the outer layer peels of, hence this process is known as onion skin erosion or exfoliation.
