GENERAL GEOLOGY

Detailed explanation-1: -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-2: -Erosion is the process where rocks are broken down by natural forces such as wind or water. There are two main types of erosion: chemical and physical. Chemical erosion occurs when a rock’s chemical composition changes, such as when iron rusts or when limestone dissolves due to carbonation.

Detailed explanation-3: -Physical weathering occurs when physical processes affect the rock, such as changes in temperature or when the rock is exposed to the effects of wind, rain and waves.

Detailed explanation-4: -Weathering Natural process by which atmospheric and environmental agents change, disintegrate, and decompose rocks Wind, -ppt download.

Detailed explanation-5: -This can happen through exfoliation, freeze-thaw cycles, abrasion, root expansion, and wet-dry cycles.
