There are two main types of physical weathering: Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart.

kinuwa mo lang yan sa website eh tas di naman yan tanong ko HHSSHA
Physical weathering acts to widen these rock fractures. Frost wedging happens when water filling a crack freezes and expands (as it freezes, water expands 8 to 11% in volume over liquid water).
How does physical weathering occur?
Physical weathering is caused by the effects of changing temperature on rocks, causing the rock to break apart. The process is sometimes assisted by water. ... Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart.
What type of weathering makes cracks?
Mechanical weathering, also called physical weathering and disaggregation, causes rocks to crumble. Water, in either liquid or solid form, is often a key agent of mechanical weathering. For instance, liquid water can seep into cracks and crevices in rock. If temperatures drop low enough, the water will freeze.
What is an example of physical weathering?
Physical Weathering Caused by Water
When you pick up a rock out of a creek or stream, you are seeing an example of physical weathering, which is also referred to as mechanical weathering. ... When the rocks drop back down they bump into other rocks, and tiny pieces of the rocks can break apart.
