the water gets into cracks of the rock then over time if the water doesn't evaporate it freezes and expands. When the ice expands the crack gets bigger when the crack gets big enough it splits the entire rock
This happens because of the way the ice forms. The ice becomes really sharp and splits the rocks in half, and also it maybe because the temperature is really cold that it breaks away time by time and cracks inbetween.
Rain water seeps into any cracks in the rock. When the water freezes in winter, the ice expands and the force can be strong enough to split the rock.
Physical weathering
It hapens erosions
Yes, air will enter rock cracks. But, if water fills the crack, during a deep freeze, the expansion of the water, as ice forms, will often widen the crack (even to split the rock).
Ice erosion is caused by glaciers that move very slowly with the help of gravity. When the glaciers move they scrape at the rock. This scraping plows, files, and carries the removed sediment elsewhere. The erosion caused when the glacier melts is considered water erosion.

Ice wedging breaks the rock apart. Water goes into cracks in the rock and when it freezes, it expands. This can cause rocks to split and eventually break. (see the related link)
In one way (ice wedging), water gets into cracks in the rock, then freezes. This force can eventually split the rock crystals. In another (moving ice), a glacier or other large mass of ice moves across the rocks surface. This can scour away loose rock by friction. (It does not require that there be imbedded rocks, but this can also occur, where rocks are pushed together until one breaks.)

The ice expands in the crack and may split the rock, as will eventually the roots of a plant.
