when water enters the cracks in the cracks in a rock and freezes it expands and pushes cracks further apart​

Answer:

Ice wedging

Water seeps into cracks in the rocks, and, as the temperature drops below freezing, the water expands as ice in the cracks. The expansion exerts tremendous pressure on the surrounding rock and acts like a wedge, making cracks wider. After repeated freezing and thawing of water, the rock breaks apart.
