Question

Quizplus · Accepted Answer

The expansion of freezing water in a crack causes mechanical stresses that eventually lead to the widening of the crack. This is known as mechanical weathering. Chemical weathering involves the breakdown of rocks through chemical reactions, while hydration is the process of water molecules binding with mineral crystals. Exfoliation is a type of mechanical weathering caused by the release of pressure on the surface of a rock, resulting in the flaking or scaling of the outer layers.
