It cracks the rock
All rocks have cracks in them. If water fills the cracks and freezes, it expands and pushes the rock apart.
when water freezes, it expands. when water freezes in cracks and pores of rocks, the force of its expansion is strong enough to split the rocks apart.
The ice expands as it freezes - which creates weak points in the rock, causing it to break apart.
The rock cracks and weathers.
As the water freezes in the cracks of rocks,the cracks expand. The process repeats itself and the rock eventually breaks.
The ice expands in the crack and may split the rock, as will eventually the roots of a plant.
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.
Since water expands when it freezes, it causes cracks in rocks when it freezes inside them.
The water expands as it is frozen and so the cracks are made wider/bigger :)
