Distinguish between physical and chemical weathering.

Question

KnowledgeBoat · Accepted Answer

Physical weathering | Chemical weathering ------------------- | ------------------- It involves rock disintegration without any change in the chemical constituents of the rock. | In this weathering, some or all of the minerals in the rocks suffer decay or alteration and transform into different chemical combinations. Agents of physical weathering include temperature changes, moisture, frost action and wind. | Agents of chemical weathering include water, oxygen, carbon or various organic acids. It is more rapid in desert climates. | It occurs in moist and cold climates. Rocks are affected to great depths. | It mostly takes place near the surface of the earth.
