Question

Explain how a plant can cause a rock to weather

Answer 1

The roots can grow where the rocks cracked and start to have roots grow in the cracks

Answer 2

Plants can cause physical weathering as their roots grow. Seeds of plants or trees can grow inside rock cracks where soil has collected. The roots then put pressure on the cracks, making them wider and eventually splitting the rock. Even small plants can cause this kind of weathering over time.
