Hydroelectric power is produced using the energy of moving water.

Which description tells how this process is accomplished?



Water flowing downstream is held up in a reservoir behind a dam. Some water moves down channels through turbines connected to generators which produce electricity.


Water flowing downstream moves through a reservoir in a dam and past turbines. It then moves through channels and cause a generator to produce electricity.


Water flowing upstream is help in a reservoir behind a dam. The water moves up through channels in the dam where it flows past turbines, moving them and creating electricity.
