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.

What type of climate has the greatest amount of rock weathering caused by rock weathering?
A wet climate in which temperatures alternate between below freezing and to above freezing.
How does the freezing and thawing cause weathering of rocks?
because it cracks the rock
Is ice freezing in a crack of a rock erosion or weathering?
Ice freezing in a crack of a rock is considered weathering.
Is ice freezing in a crack of a rock considered weathering or erosion?
Ice freezing in a crack of a rock is considered weathering.
What type of climate has the greatest amount of rock weathering caused by frost action?
A wet climate in which temperatures alternate between below freezing and to above freezing.
Is water freezing in cracks in a rock a physical weathering?
it is a physical weathering.
What is water freezing in the crack of a rock an example of?
Water freezing in the cracks of rock is an example of Mechanical Weathering also referred to as Physical Weathering.
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.
What factors cause mechanical weathering?
Mechanical weathering breaks rock into pieces by freezing and thawing,release of pressure, growth of plants, action of animals, and abrasion
Which of theses can cause the expansion and contraction of rocks due to weathering?
Warming during the day, will expand the rock. Freezing during the night, will contract the rock.
