How Does Wind Weather Rocks
There are four main types of weathering. These are freeze-thaw, onion skin (exfoliation), chemical and biological weathering. Most rocks are very hard. However, a very small amount of water can cause them to break.

How does freezing water cause the weathering of rocks?

Freeze-thaw Weathering

When water seeps into rocks and freezes, it expands and causes the rock to crack. When water transforms from a liquid state to a frozen state, it expands. Liquid water seeps into existing cracks in the rock, freezes and then expands those cracks.

What process involves the breaking of rocks over time due to wind?

Weathering is a process of breaking down of rock into smaller pieces. Erosion is the process of moving these pieces (called sediment) by wind, water, ice, and gravity.
