Answer:
When water or melted ice soaks into the cracks of rocks and freezes, thus causing stress in the rocks due to expansion, causing the rock to break. This is called Freeze-Thaw.
Explanation:
- Mechanical weathering is the process of breaking big rocks into little one by the means of Temperature , roots of plants , water .
- Little animals also help by burrowing and digging through the ground. Temperature also affects the land . The cool nights and hot days always cause things to expand and contract. That movement can cause things to break apart . Roots and plants also push into the rocks to crack and break apart.
- Scientist have observed a process called freeze-thaw.
- That process occurs when the water inside of rocks freezes and expands . That expansion cracks the rocks from the inside and eventually breaks them apart .
- The freeze-Thaw cycle happens over and over again and the break finally happens. Another word for it is frost wedging. There are already some cracks in boulders and water can get inside these.
- When that water expands, the rock is crunched between two expanding pieces of ice instead of being forced apart into separate pieces.
