Solution

  1. Yes, burrowing animals widen the fissures in the rocks. Rocks become weak and disintegrate.
  2. The roots of the trees and other plants penetrate in the soil, they grow in size, exert pressure on rocks, widen cracks in the rocks and rocks break. Many microscopic organisms such as algae, lichens, bacteria, moss, etc produce chemicals and they break down the outer layer of the rock. These chemicals are responsible for the physical and chemical weathering of rocks.
  3. The stone quarrying causes the anthropogenic weathering.
