GENERAL GEOLOGY

Detailed explanation-1: -Physical weathering, also called mechanical weathering, is a process that causes the disintegration of rocks, mineral, and soils without chemical change. The primary process in physical weathering is abrasion (the process by which clasts and other particles are reduced in size).

Detailed explanation-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.

Detailed explanation-3: -Physical weathering is the breaking of rocks into smaller pieces. This can happen through exfoliation, freeze-thaw cycles, abrasion, root expansion, and wet-dry cycles. Exfoliation: When temperature of rocks rapidly changes that can expand or crack rocks.

Detailed explanation-4: -Mechanical weathering involves physically breaking rocks into fragments without changing the chemical make-up of the individual minerals that make up the rock.

Detailed explanation-5: -Abrasion weathering-forces such as wind and water cause rocks to breakdown into smaller pieces. Exfoliation weathering-rocks expand and break as pressure is released from unloading. Frost wedging-rocks break as water freezes and expands. More items •12-Oct-2021
