What happens when water flows through a dam?

What allows water to flow through a dam?
The water is pumped out.

What is the job of a turbine?
When it spins, it makes sparks causing electricity.
It moves the energy from the flow of water to a generator.
It slows down the speed of the water to keep it at a steady pace.
It controls the water so it can be pumped back up the dam.
What does a generator do?
It spins when the water passes through it.
It moves the water from a higher elevation to a lower elevation.
