Freeze-thaw weathering is a type of physical weathering caused by repeated cycles of freezing and thawing of water in cracks and pores of rocks. When water freezes, it expands, creating internal pressure that can crack the rock. Over time, this process can break down rocks into smaller pieces.
What else can I help you with?
How long does freeze thaw weathering take?
Freeze-thaw weathering is a gradual process that can occur over many years or even centuries, depending on the frequency of freeze-thaw cycles and the type of rock or material being weathered. Factors such as climate, temperature fluctuations, and the composition of the rock can also influence the speed at which freeze-thaw weathering occurs.
What is the freez thaw weathering word equation?
The word equation for freeze-thaw weathering is: Water (liquid) + Freeze (cold temperatures) + Thaw (warm temperatures) = Cracks and weathering of rocks. This process occurs when water seeps into rocks, freezes and expands, causing the rock to crack, and then thaws, repeating the cycle and breaking down the rock over time.
What is another example of freeze-thaw weathering?
Another example of freeze-thaw weathering is when water seeps into cracks in rocks or pavement, freezes overnight, expands, and then thaws during the day. This repeated process causes the rock or pavement to crack and break apart over time.
Is Physical weathering what happens in freeze thaw?
Yes, physical weathering involves the breakdown of rocks into smaller pieces through various processes, including freeze-thaw. In freeze-thaw weathering, water seeps into cracks in rocks, freezes, and expands, causing the rock to crack and break apart over time.
What type of weathering is freeze thaw?
When water freezes it expands by around 10 percent. When water that is trapped in cracks or porous layers in rock freezes and expands, it exerts pressure on the rock and splits it into smaller pieces. This leads to erosion.
Freeze-thaw is an example of this?

What types of mechanical weathering are there?
freeze and thaw, exfoliation and abrasion
3 example of physical weathering?
Freeze - Thaw weathering Onion skin weathering Erosion from rain water
What are two processes that can break rocks apart?
freeze-thaw weathering and onion skin weathering.
Is freezing and thawing chemical weathering or mechanical?
Freeze/thaw cycles are an example of mechanical weathering of rock.
What are the rock fragments resulting from freeze thaw weathering?
These are known as scree or talus.
What are 5 weathering terms?

How long would it take for granite to break up because of freeze-thaw weathering when it is next to a volcano?
It cannot be concluded from the information given. Whether or not a rock is near a volcano would not significantly effect freeze-thaw weathering. That is primarily controlled by climate.
