GEO River Erosion

How will channel velocity change from the headwaters to the mouth of the river?

• It will increase

• it will decrease

• it will stay the same

• it will increase then decrease

As a stream's velocity slows, the smallest particles are deposited first.

• true

• false

Which part of a stream's load moves the slowest?

• dissolved load

• suspended load

• bed load

• they all move the same rate

The dissolved load is ___________________.

• the chemically weathered sediments carried in solution by a river

• the find sand, silt, and clay particles held up and carried with the water

• the larger sediments that bounce, roll, or slide along the bottom of the stream bed

The suspended load is ___________________.

• the chemically weathered sediments carried in solution by a river

• the find sand, silt, and clay particles held up and carried with the water

• the larger sediments that bounce, roll, or slide along the bottom of the stream bed

The bed load is ___________________.

• the chemically weathered sediments carried in solution by a river

• the find sand, silt, and clay particles held up and carried with the water

• the larger sediments that bounce, roll, or slide along the bottom of the stream bed

Which of the following statements accurately describe this river channel? Choose ALL that apply

• bedrock channel near the headwaters where erosion is focused downwards

• alluvial channel near the mouth where erosion is focused laterally

• steep gradient

• shallow gradient

Does an incised meander form due to river erosion or river deposition?

• erosion

• deposition
