The rock cracks and weathers.
Since water expands when it freezes, it causes cracks in rocks when it freezes inside them.
When water freezes in cracks, it expands as it turns into ice. This expansion puts pressure on the surrounding rock, causing the crack to widen and potentially leading to fracturing and breaking of the rock over time. This process is known as freeze-thaw weathering and can cause significant damage to rocks and structures.
The type of physical weathering that occurs when water seeps into cracks of rock and freezes is called frost wedging. As the water freezes, it expands, exerting pressure on the rock and causing it to disintegrate. Over time, this repetitive process can break the rock into smaller fragments.

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.
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 .
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.
The type of weathering that involves water filling cracks in a rock is called frost wedging. When water enters the cracks in a rock and freezes, it expands, causing the crack to widen and eventually break apart the rock.
When water freezes inside rocks, it expands as it turns into ice. This expansion creates pressure that can cause the rock to crack or break apart. Over time, repeated freezing and thawing cycles can weaken the rock and contribute to its breakdown.
There are four types of water erosion. They are freeze-thaw, biological, chemical, and exfoliation erosion. Freeze-thaw erosion occurs when water seeps into cracks or joints in rocks and then freezes.
