The rock cracks and weathers.
the water freezes and then cracks the rock
It cracks the rock
Since water expands when it freezes, it causes cracks in rocks when it freezes inside them.
As the water freezes in the cracks of rocks,the cracks expand. The process repeats itself and the rock eventually breaks.

Say some water gets into the crack inn a rock, the water freezes and scince water expands when it freezes the rock cracks even more.
Each time the water freezes, it expands, gradually widening the cracks in the rock. Eventually the rock will break along the lines of the crack.
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
All rocks have cracks in them. If water fills the cracks and freezes, it expands and pushes the rock apart.

If water is caught in cracks in the rock and it freezes it expands. This causes the rock to chip off.
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 .
