• no erosion after a storm

• there will be no observable changes because of the storm.

• a lower rate of erosion after a storm

• a higher rate of erosion after a storm

A river starts as a steep channel in the mountains. It then leaves the mountains and enters a flatter area of land. It meanders across a plain and then enters the ocean. At which point would the river describe form a delta?

• when the river enters the ocean

• when the river is in the mountains

• when the river leaves the mountains

• when the river meanders across a plain

Which statement about floodplains is true?

• Floodplains are good places to grow crops.

• Floodplains are an example of stream erosion.

• Floodplains are places where the soil is infertile, not good for agriculture.

• Floodplains are narrow, steep-walled, and V-shaped.

The steeper the slope, the ________ the stream.

• slower

• faster

• curvier

• wider

What kind of river produces meanders like the ones in the image?

• Young River

• Old River

• Age does not matter

The diagram represents a stream as it travels from the mountains across the plains and into the ocean. Image C indicates a triangular-shaped depositional feature where the stream enters the ocean. What is this feature called?
