GEOLOGY

Detailed explanation-1: -Erosion is when materials, like soil or rocks, are moved by wind or water. All these materials are called sediments. Deposition is when those sediments are deposited, or dropped off, in a different location. These processes change the way the surface of the earth looks over time.

Detailed explanation-2: -Dunes When the wind hits an obstacle, the wind slows down, depositing the heavier material. The material collects, creating an additional obstacle and eventually forming a mound that buries the original obstacle. D. The mounds of wind-deposited sand are called dunes.

Detailed explanation-3: -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-4: -Erosion is the removal and transportation of rock or soil. Erosion can move sediment through water, ice, or wind. Water can wash sediment, such as gravel or pebbles, down from a creek, into a river, and eventually to that river’s delta.

Detailed explanation-5: -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.
