Forces Shaping the Earth: Deposition

The video explains the process of deposition, where sediment settles in new locations as water slows down. It covers how sediments are transported and deposited in rivers and streams, often forming structures like alluvial fans and deltas. Examples include the alluvial fan in Nevada and the Nile River delta. The Mississippi Delta is also highlighted as a significant example of sediment deposition.

What happens to sediments when water flow slows down?

• They dissolve in water.

• They settle to the bottom.

• They evaporate.

• They become lighter.

Where are sediments most likely to be deposited in a river?

• At the river's source.

• On the inside bend of a river.

• In the middle of a fast-flowing stream.

• On the outside bend of a river.

What is an alluvial fan?

• A type of delta.

• A mountain peak.

• A type of river bend.

• A structure formed by sediment deposition on flat terrain.

How is the Nile River delta formed?

• By volcanic activity.

• By glacial melting.

• By sediment deposition in the Mediterranean Sea.

• By tectonic plate movement.

Where does the Mississippi River deposit its sediments?

• In the Great Lakes.

• In the Pacific Ocean.

• In the Gulf of Mexico.

• In the Atlantic Ocean.
