GEOLOGY

Detailed explanation-1: -Weathering occurs in situ (on site, with little or no movement), and so is distinct from erosion, which involves the transport of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity.

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: -5. State true or false: Weathering involves moving soil particles and rocks to other places with the action of ice, water, and wind. Explanation: Moving of soil particles to other places does not take place in weathering. This process is known as soil erosion.

Detailed explanation-4: -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-5: -Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts. These reactions occur particularly when the water is slightly acidic.
