Physical weathering, or mechanical weathering, refers to processes that wear away or break down the physical structure of rock and stone without altering it chemically. This can include processes by which rock is cracked or shattered; for instance, when falling rocks smash into each other and break apart. Physical … See more In exfoliation, rocks formed under tremendous pressure beneath the Earth are brought to the surface. Without the extreme pressure, the tops of these rocks expand, and split apart from the rock under them. … See more You've probably seen a rusty piece of iron.
