Examine the different types of weathering.

Solution

here are three main types of weathering :
1. Physical or Mechanical, 2. Chemical and 3. Biological.

1. Physical or mechanical weathering is responsible for the disintegration of rocks or development of stresses in them. It is brought about mainly by changes in temperature and freezing action of water.

2. Chemical weathering is the process that causes rocks to rot or decay due to the action of air and water on the minerals present in the rocks.

3. Biological weathering takes place by plants and animals. Grazing by large animals uncovers the soil, thus increasing surface runoff and soil erosion. Cracks may be caused and widened by root pressure of plants.
