Explanation:
Physical weathering is the disintegration of rocks into smaller chunks in nature.
Water is one of the agents that causes physical weathering.
- during periods of low temperature especially the summer, water usually collects within rock cavities.
- When temperature drops, the water freezes and expands.
- Periodic freezing and thawing of ice leads to physical weathering.
- Also, in tropical regions, alternate wetting and drying of rocks occur.
- When a rock is wet, it absorbs more water and it volume expands.
- Drying occurs and it loses the water.
- This continuous process leaves cracks in rock.
