mechanical weathering

This area has arid climate & cone degradation is a product of mechanical weathering.

Hydraulic action occurs when the motion of water against a rock surface produces mechanical weathering.

Mechanical weathering is rapid in cold desert regions.

The rounding of the granite blocks is a result of both chemical and mechanical weathering.

It has a high blocking temperature, is resistant to mechanical weathering and is chemically inert.

Physical weathering is also called mechanical weathering, disaggregation.

The relative importance may change, as can be seen in the increasing importance of mechanical weathering in cold and dry climates.

This form of mechanical weathering can be caused by freezing and thawing, unloading, thermal expansion and contraction, or salt deposition.

Living organisms may contribute to mechanical weathering (as well as chemical weathering, see 'biological' weathering below).

The process of deflation of the finer constituents from deserts probably accentuates the dominance of coarse waste, initially brought about by the importance of mechanical weathering.
