Question Question 5
Discuss the role of plants and animals in biological weathering.
Role of plants — The penetration of roots in the rock cracks widens the cracks and disintegrates the rocks. The uprooting of trees by winds also breaks the rocks.
Role of animals — Animals such as worms, rabbits and moles dig burrows in the ground. In the process, they loosen the ground and disintegrate the rocks.
