Because when water seeps into cracks and freezes, the material gets pushed outwards, because water exapands as it freezes. This process is called ice wedging.
When water freezes, it expands and exerts pressure on the rock walls, causing the cracks to widen. Over time, repeated freeze-thaw cycles can further widen the cracks as the ice continues to expand and contract. This process eventually weakens the rock structure, leading to larger cracks.
Freezing water can affect the weathering of rocks on a mountain's pinnacle because the frozen water will expand within the cracks of the rocks of the mountain's pinnacle. The ice accumulations will also grow larger which will also affect the weathering of the rocks.
Infiltration is the movement of surface water into rocks or soil through cracks or pore spaces.
Ice wedging occurs when water seeps into cracks of rocks, freezing and expanding, putting pressure on the rock. As the ice thaws and refreezes, the repeated expansion and contraction forces the crack to widen, eventually causing the rock to break apart. This process leads to mechanical weathering of rocks.
Water expands when it freezes, therefore it tends to cause the rocks to crack (or perhaps I should say, it causes existing cracks to get larger, leading to the disintegration of the rock).

cracks open wider
Freezing water can affect the weathering of rocks on a mountain's pinnacle because the frozen water will expand within the cracks of the rocks of the mountain's pinnacle. The ice accumulations will also grow larger which will also affect the weathering of the rocks.
cracks open wider
Weathering is the process which breaks rocks into smaller bits. This is one type of weatheringPhysical weathering is a physical action which breaks up rocks : An example of this is called freeze-thaw weathering when water gets into tiny cracks in rocks. When the water freezes it expands, if this is repeated the crack grows and bits eventually break off.
All rocks have cracks in them. If water fills the cracks and freezes, it expands and pushes the rock apart.
The water can get inside and then freeze which in turn cracks the rocks open.
Infiltration is the movement of surface water into rocks or soil through cracks or pore spaces.
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.
b. water freezing in the cracks of exposed rocks
yes it does when water freezes it expands the rocks cracks which he water went inside
Rain and running water can enlarge existing cracks in rocks through its erosive powers. Freezing water in a rock crack will expand, causing additional fracture.
