While researching a topic, a student has taken the following notes:

• A U-shaped curve in a river channel is called a meander.
• A meander forms when water erodes sediment from one side of the riverbank and redeposits that sediment on the opposite side.
• Meanders will gradually change shape and migrate downstream over time.
• A river with high sinuosity has many meanders, and a river with low sinuosity has few.
• The Willapa River in the United States has high sinuosity.

The student wants to define the term “high-sinuosity river.” Which choice most effectively uses relevant information from the notes to accomplish this goal?

A

A high-sinuosity river is one that has many meanders, or U-shaped curves.

B

Over time, the many meanders in the high-sinuosity Willapa River will change shape and migrate downstream.

C

High sinuosity is caused by the erosion and redepositing of sediment in a riverbank over time.

D

A high-sinuosity river has U-shaped curves called meanders that will gradually change shape and shift downstream.
