Rocks cannot freeze but the water inside them however can
If this happens repeatably the water gradually creates cracks in the rock and every time it freezes again it widens this crack, eventually the rock can split into many pieces, this is known as the freeze thaw effect .
erosion
The water continuously freezes and thaws eventually splitting the rock into pieces creating sand.
When ice forms in cracks in rocks, the kind of weathering is known as mechanical weathering. The type of mechanical weathering that freezes and thaws is frost wedging.
The crack would expand because the water in the rock, as it freezes, expands.
Water goes in a cracks. When it gets cold it thaws and freezes. It also turns into a crystal form. Then it takes a lot of space and cracks a rock.
It cracks the rock
For example,when ice thaws, it becomes water, which can go into holes of a rock. When the water freezes, it expands & puts pressure on the rock which causes it to break apart/weather
If it freezes just a little it becomes cold water, but if it freezes more it becomes ice.
Water gets into cracks in the rocks. When the water freezes into ice it expands. This can crack rock. When this happens repeatedly the rocks break into increasingly smaller particles until they are soil. .
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.
When the water in the cracks freezes, it expands by 9 to 10 percent, exerting pressure on the rock, according to BBC Bitesize. This action can widen the cracks in the rock, and when the temperature rises above freezing, the ice thaws, allowing the water to seep further into the cracks.When the water in the cracks freezes, it expands by 9 to 10 percent, exerting pressure on the rock, according to BBC Bitesize.

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.
