Streams & Coasts

Front

What is a watershed?

Back

A watershed is the entire area drained by a river and its tributaries.

Front

What is the largest size sediment that can be carried by water flowing at 100 cm/sec?

Back

3 cm

Front

What happens when a stream or river starts to slow down?

Back

It deposits larger rocks, but continues carrying finer sediment.

Front

How does stream velocity change between points with different slopes?

Back

The stream velocity is less when the slope of the land decreases.

Front

What is the primary agent of erosion that creates landforms?

Back

Water is the primary agent of erosion that creates landforms.

Front

Define sediment.

Back

Sediment is small solid particles that are transported by water, wind, or ice.

Front

What is the process of erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes.

Front

What is deposition in the context of streams?

Back

Deposition is the process where sediments are laid down or settled when the energy of the transporting medium decreases.

Front

What factors affect the velocity of a stream?

Back

Factors include the slope of the land, the volume of water, and the roughness of the streambed.

Front

What is a delta?

Back

A delta is a landform that forms at the mouth of a river where it meets a body of water, characterized by sediment deposition.
