GEOLOGY

Detailed explanation-1: -When the velocity of wind or water slows, eroded sediment is deposited in a new location. The sediment builds up in a process called sedimentation and creates fertile land.

Detailed explanation-2: -Slower moving water erodes material more slowly. If water is moving slowly enough, the sediment being carried may settle out. This settling out, or dropping off, of sediment is deposition. The curves are called meanders because they slowly “wander” over the land.

Detailed explanation-3: -Deposition along a riverbed occurs where the speed of the water slows down and can result in a sandbar.

Detailed explanation-4: -As sediment is transported down stream, the water flow helps to shape the planet’s surface by carrying away the eroded material away from some regions and depositing it in others 19.

Detailed explanation-5: -As the flow velocity increases, only larger and larger particles will be deposited. Particles between these two curves (either moving too slow or being too small to be eroded or deposited) will be transported in the stream.
