Why Exfoliation is also known as onion peeling or onion weathering?

Answer: Exfoliation domes are common, which show layers of the granite ‘peeling’ like an onion due to the reduced pressure allowing expansion of the rock. The crust, also known as the lithosphere, is the top layer and is made up of rock material.

What are the 5 agents of weathering?

Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion.

Is block a disintegration?

Block Disintegration Granular Disintegration
It is caused by repeated contraction and expansion of rocks due to freezing of water in night and their melting during the day time. So it mainly caused by the action of frost caused as result of temperature changes. It is mainly caused by changes in temperature.

What causes exfoliation weathering?

Exfoliation is a form of mechanical weathering in which curved plates of rock are stripped from rock below. Most people believe exfoliation is caused by instability as a result of drastically reduced pressure at the earth’s surface allowing the rock to expand. Exfoliation domes are best developed in granitic rock.
