Please can someone tell me how long the freeze thaw process takes on a rock, thanks :) xx
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.
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.
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.
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 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.
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.

It would depend on the type of rock and the temperature changes involved.

Freeze thaw weathering would take place in the cracks on the rocks surface. Depending how long the rock is left, and what type of rock it is, the freeze-thaw would widen the cracks and eventually split the rock.

Freeze/thaw cycles are an example of mechanical weathering of rock.
Freeze-thaw weathering occurs in regions with temperature fluctuations around the freezing point of water. Water seeps into cracks in rocks, freezes, expands, and pushes the rock apart upon thawing. This cycle of freezing and thawing weakens the rock over time, eventually causing it to break apart.
These are known as scree or talus.
