How does freezing water cause the weathering of rocks?  The freezing water—

• keeps the rocks in place

• makes the rocks last longer

• expands cracks and breaks rocks

• causes rocks to fall in landslides

These rocks were broken apart from the continuous freeze/thaw of water in the cracks of the rocks. This is an example of:

• ice wedging

• acid rain

• permeability

• abrasion
