What do you call the area where water is stored behind a dam?

• reservoir

• generator

• refuge

• turbine

What happens when water flows through a dam?

• The water evaporates.

• The water turns a turbine.

• The water is pumped back up.

• The water creates sparks making electricity.

What allows water to flow through a dam?

• The water is pumped out.

• The water constantly flows through without ever stopping.

• The water is pushed out when a motor is turned on.

• The water is released from a higher elevation to a lower elevation.

What is the function of a turbine?

• When it spins, it makes sparks, inducting electricity.

• It transfers the energy from the flow of steam or water to the generator.

• It speeds up the steam or water to keep it at a steady pace.

• It controls the steam or water so it can be pumped around in a cycle.

Hydroelectric power is based on . . .
