Water expands when it freezes. In winter, water gets into minute cracks in the rocks and then as it freezes it expands and makes the cracks bigger. So more water gets in then freezes so the cracks get bigger still until the rocks break apart.
Frostwegging
It explodes...?
Water can do this if it freezes
Erosion ... breaking of the rocks.
