Physical
It cracks the rock
The ice expands in the crack and may split the rock, as will eventually the roots of a plant.
yes it does when water freezes it expands the rocks cracks which he water went inside
Joints. This particular type of jointing is called "frost-wedging", and is a type of physical weathering.

Physical
It cracks the rock
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).
cracks open wider
It is a form of weathering known as frost wedging.
cracks open wider
It is called "frost weathering" or "freeze-thaw weathering" and occurs because water that freezes within the cracks in rocks will expand, compressing and eventually fracturing the rock.
As the water freezes in the cracks of rocks,the cracks expand. The process repeats itself and the rock eventually breaks.
It is a form of weathering known as frost wedging.
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.
All rocks have cracks in them. If water fills the cracks and freezes, it expands and pushes the rock apart.
