Answer Details
The peeling off of the surface layers of rounded boulders during mechanical weathering is called exfoliation. Exfoliation occurs due to the expansion and contraction of rock surfaces caused by temperature changes. During the day, rocks absorb heat from the sun and expand, and at night they cool down and contract. Over time, repeated expansion and contraction cause the outer layers of the rock to peel off in thin sheets. Exfoliation is a common process in areas with extreme temperature variations, such as deserts and mountainous regions.
