I gave my students this multiple choice question: Long shore currents are ocean waves that strike beaches at extremely small angles. In areas where long shore currents exist, what effect do they have on land areas?

Only one answer is correct among these 4 choices:
- They build mountains.
- They cause earthquakes.
- They move sand, creating sandbars.
- They create inland saltwater rivers.

Could you tell me which one is correct?

They move sand, creating sandbars.
