Answer the question in one word:-
1) Disintegration and decomposition of rocks.

2) A process which wears down the rocks.

3) The breaking up of exposed rocks due to change in temperature,frost,plants and winds.

4) Unequal heating causes expansion in rocks resulting in breakdown of rocks.​

Answer 2

Answer:

1. Weathering - the disintegration and decomposition of rock at or near the surface of the earth. It affects the rocks in place and no transport is involved. This distinguishes weathering from erosion.
2. Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.
3. The Physical weathering are referred as the mechanical weathering in which the weakening of rocks are mainly followed by the disintegration of physical or mechanical forces that includes actions on the rocks by frost chattering, abrasion, temperature fluctuations as well as salt crystal growth.
4. Unloading or release of stress in a rock that produces expansion joints can cause exfoliation. A reduction in stress occurs when rocks previously buried deeply are exposed due to erosion of overlying rocks, or when ice sheets that bury rocks melt.
