Erosion and Deposition Rivers/Streams

Front

What is deposition?

Back

Deposition is the process by which sediment and other materials are left and dropped at a new location.

Front

Which type of stream erodes more rock?

Back

A fast-moving stream erodes more rock than a slow-moving stream.

Front

What forms a delta?

Back

A delta forms when a river enters a larger body of water, such as an ocean, and deposits sediment.

Front

Where does the greatest amount of erosion occur in a stream?

Back

The greatest amount of erosion occurs at the highest elevation point in the stream.

Front

What process creates deltas?

Back

Deltas are created by deposition by water.

Front

What is erosion?

Back

Erosion is the process of breaking down and removing soil and rock from one location to another.

Front

How do rivers change as they flow from mountains to plains?

Back

Rivers typically start steep in mountains, then meander across plains, and finally enter larger bodies of water.

Front

What is the role of sediment in rivers?

Back

Sediment is material that is transported by water and can be deposited to form features like deltas.

Front

What factors affect the speed of a river?

Back

The speed of a river is affected by the slope of the land, the volume of water, and the shape of the riverbed.

Front

What is a river's profile?

Back

A river's profile is a cross-sectional view showing the changes in elevation along the river's course.
