Explanation:
Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
Some agents of weathering are wind, water, glacier and gravity.
- In physical weathering, rocks are broken down mechanically into smaller bit.
- Freezing and thawing allows for the propagation of physical weathering.
- Water within cracks will expand when they freeze significantly.
- This will further expand and widen the cracks.
- When the ice thaws the stress is relieved.
- When the process continues on and on over the year, a rock will eventually break down.
- This is common around the temperate and polar regions.
