Best Answer

Frost wedging occurs when liquid water flows into rock cracks and crevices and then expands upon freezing. The wedging creates a deeper or larger crack which can then be further expanded by additional frost wedging. Additionally, the frost wedging creates additional rock surface which can then be attacked by chemical weathering, mainly by the natural acidity of rainwater.

Does freezing then thawing a mechanical weathering of a rock?

Yes, it is a form of mechanical weathering. Water manages to get into a crack in a rock, and with cold temperatures, freezes. When transferring from a liquid to a solid, the molecules of water expand by crystallization, widening the crack in the rock.


What cause mechanical weathering?

Mechanical weathering breaks rock into pieces by freezing and thawing,release of pressure, growth of plants, action of animals, and abrasion


What are two ways the mechanical weathering changes rocks?

Mechanical weathering is any type of rock break down or change that is not caused by a chemical change in the rock structure. It can be caused by freezing and thawing of water in the rock or hotter temperatures making the rock expand and crack.
