- 9What Is Oxidation?When Oxygen And Water React.

- 11What Is Mechanical Weathering?Where something physically break down the rock into smaller pieces, without changing its properties.
- 12What Is Freeze-Thaw1. Water collects in a rocks cracks.
2. Water freezes and then expands forcing the cracks in the rock to expand.
