Exfoliation is a form of _________.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. physical weathering.
Exfoliation is a form of physical weathering, also known as mechanical weathering. It involves the breaking down of rocks without any chemical changes, typically caused by temperature fluctuations, pressure release, or freeze-thaw cycles. These processes lead to the peeling or flaking of the outer layers of rock. Unlike chemical weathering, which alters the rock's composition, exfoliation solely impacts the physical structure. It commonly occurs in areas with significant daily temperature variations.
