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.

Detailed explanation-2: -Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.

Detailed explanation-3: -Wind can cause weathering by blowing grains of sand against a rock, while rain and waves cause weathering by slowly wearing rock away over long periods of time.

Detailed explanation-4: -Three agents of physical weathering that can cause abrasion are moving water, wind and gravity.

Detailed explanation-5: -Agents responsible for weathering include ice, salts, water, wind and plants and animals. Road salt and acids represent a form of chemical weathering, as these substances contribute to the wearing away of rocks and minerals as well.
