Question

How does water cause weathering? Explain.

Answer 1

Weathering: It is the process of breaking down rocks into smaller particles to form the soil. It may be due to physical factors (temperature, wind, etc.), chemical factors (oxidizing, reducing agents), and biological factors (growing of lichens, ferns, or burrowing animals).

Weathering by water:

1. It is a form of physical weathering of soil.
2. The high temperature and presence of water cause corrosive humidity which results in an unequal expansion and contraction of rocks bringing about a breakdown.
3. The action of water and wind action together causes weathering of rocks to form smaller particles and then form soil.
4. This form of weathering occurs along shorelines where both wind and water currents are very high.
