GEOLOGY

Detailed explanation-1: -Physical weathering involves the breakdown of rocks and soils through the mechanical effects of heat, water, ice, or other agents. Chemical weathering involves the chemical reaction of water, atmospheric gases, and biologically produced chemicals with rocks and soils.

Detailed explanation-2: -Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. 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.

Detailed explanation-3: -The movement of sediments by wind, water, ice, or gravity is called erosion.

Detailed explanation-4: -Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.

Detailed explanation-5: -The two main types of weathering are physical and chemical weathering. This page describes mechanical (physical) weathering (and more).
