Plants need water, and water can weather rocks.
All of the above options are correct:
- Chemical reactions in plants can release acids that break down minerals in rocks, causing them to break into smaller pieces.
- Plants can attract animals, such as burrowing animals, which can dig into rocks and cause physical weathering.
- When seeds sprout and roots grow, they can exert pressure on rocks, causing them to crack and break apart.
- Plants require water for growth, and water can seep into cracks in rocks and freeze, expanding and causing the rocks to break. Additionally, plant roots can absorb water and release it back into the surrounding environment, promoting chemical weathering.
