- Cycles of freezing and thawing water cause ice wedging
- Ice wedging is a kind of mechanical weathering
- Therefore, cycles of freezing and thawing water cause mechanical weathering

- Cycles of freezing and thawing water cause mechanical weathering
- Mechanical weathering means breaking down rocks from a larger whole into smaller pieces by mechanical means
- So, rocks will be broken down from a larger whole into smaller pieces by cycles of freezing and thawing water

So, rocks will be broken down from a larger whole into smaller pieces by cycles of freezing and thawing water
[Question]A large rock breaks into small pieces within 10 years. Which process is most likely responsible for breaking the large rock into small pieces within 10 years?
[Context]- Cycles of freezing and thawing water cause ice wedging
