lake river aquifer wetland
I gave my students this multiple choice question: During a portion of the water cycle, water falls to Earth's surface as precipitation. Some of this water runs off into channels and keeps moving until it ends up in the ocean. Which best describes the water in the channels?

Only one answer is correct among these 4 choices:
- lake
- river
- aquifer
- wetland

Could you tell me which one is correct?

river
