GEOLOGY

Detailed explanation-1: -Deposition is the laying down of sediment carried by wind, flowing water, the sea or ice. Sediment can be transported as pebbles, sand and mud, or as salts dissolved in water. Salts may later be deposited by organic activity (e.g. as sea shells) or by evaporation.

Detailed explanation-2: -The movement of sediments by wind, water, ice, or gravity is called erosion. Sediments are dropped in a new location. The process of dropping sediments in a new location is called deposition.

Detailed explanation-3: -Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth’s surface. Sedimentary rocks often have distinctive layering or bedding.

Detailed explanation-4: -Erosion and weathering include the effects of wind and rain, which slowly break down large rocks into smaller ones. Erosion and weathering transform boulders and even mountains into sediments, such as sand or mud.
