Water will expand when heated. It it will also expand when frozen. Water seeping into narrow cracks in rock, could, when becoming frozen in winter, expand and force the narrow crack to become wider.

How do rocks change when water in them freezes?
As the water freezes in the cracks of rocks,the cracks expand. The process repeats itself and the rock eventually breaks.
Why do rocks crack when water has frozen on the surface of a rock?
When water freezes it increases it's volume. So, if it freezes in a crack in the rock, it will exert pressure in the rock. This pressure may be enough to widen the crack. or known as hydro wedging
What occurs when water seeps into the cracks of rocks and then freezes?
Water expands when it freezes, therefore it tends to cause the rocks to crack (or perhaps I should say, it causes existing cracks to get larger, leading to the disintegration of the rock).
How does ice break rock?
It can do this in two ways. # The Ice can hold rocks in itself and rub these (like sandpaper) across other rocks as it moves, this causes the rocks being rubbed together to break.This is called abrasion. # It can also break rock as it freezes, this is because when water freezes it expands and thus if water enters a crack in a rock then freezes in the crack the ice will try to force the crack open and over time this breaks up the rock. This is called freeze-thaw.
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 happens if water freezes in a crack of a rock?
The crack would expand because the water in the rock, as it freezes, expands.
Do rocks expand during the day?
If there is water in the gap, it will freeze. As water expands when it freezes, the crack will be opened wider. This process is called freeze-thaw. Hope that helped!
How do rocks change when water in them freezes?
As the water freezes in the cracks of rocks,the cracks expand. The process repeats itself and the rock eventually breaks.
How are rocks weathered by frost action?
Rocks are weathered by frost action when water fills in a crack and freezes into ice causing the crack to expand. This weathers the rock this thaws the rock and greatly damages all of the weathering processes.
Water works to expand joints in rocks because it expands as it evaporates true or false?
No. Water expands when it freezes, causing the rocks to crack and break.
At what temperature does water expand?
when it is in the form of ice. When water freezes it expands. If a rock has a crack in it and water goes in the crack and freezes, it will expand and melt over and over. eventually it can split the rock.
How can rocks be broken up in cold climate?
Because if the water goes in the crack and freeze, the crack will expand
How does freezing water cause rocks to weathering?
Water goes into small cracks in the rocks and then freezes. Water expands as it freezes and the expansion pushes outwards on the crack in the rock making it bigger. Eventually this process causes the rock to crack and flake apart
Why do rocks crack when water has frozen on the surface of a rock?
When water freezes it increases it's volume. So, if it freezes in a crack in the rock, it will exert pressure in the rock. This pressure may be enough to widen the crack. or known as hydro wedging
How does freezing and thawing cause rocks to break into smaller pieces?
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.
Does water expand?
When it freezes.
