• ponds

• lakes

• rivers

Which cities have more consistent (stable) temperatures all year round?

• climate

• hydropower

• currents

• moderators

With currents, ​ (a)   water travels to the northern part of the world and ​ (b)   water travels to the southern part. As water reheats, these waters replace each other and move.

The movement of water to generate (create) electricity

• currents

• hydroelectricity

• specific heat

• climate

Put the steps in the process of creating hydroelectricity in order.

• Turbine turns a generator.

• Water flows through a turbine.

• Generator converts (changes) kinetic energy to electrical energy.

• Water is moved into a power plant (a place where electricity is created).
