It cracks the rock
Physical
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
Rain water seeps into any cracks in the rock. When the water freezes in winter, the ice expands and the force can be strong enough to split the rock.
Ice wedging can break apart rocks when water seeps in cracks of roads or rocks and continues freezes and thaws until the rock eventually creates a pot hole
There are four types of water erosion. They are freeze-thaw, biological, chemical, and exfoliation erosion. Freeze-thaw erosion occurs when water seeps into cracks or joints in rocks and then freezes.
It cracks the rock
It is a form of weathering known as frost wedging.
It is a form of weathering known as frost wedging.
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).
Because when water seeps into cracks and freezes, the material gets pushed outwards, because water exapands as it freezes. This process is called ice wedging.
Physical
The one type of frost action is frost wedging, which occurs when water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart.
Ice wedging, also called frost wedging or frost shattering is a process where water seeps into cracks in rocks and freezes. Since water expands when it freezes this cpushes the cracks further open, eventually breaking the rock apart.

Ice naturally makes cracks when it is frozen. Not large cracks, but cracks. Water seeps in through these cracks and freezes them. The crack expands due to the frozen water, or new ice. The cycle continues over and over again until the piece of ice finally breaks.
