Patterns of Circulation in the Atmosphere

What causes winds?

• Temperature differences between regions

• The rotation of the Earth

• The gravitational pull of the moon

• Ocean currents

How does wind energy affect wind power?

• Wind energy increases wind power by providing a renewable source of energy.

• Wind energy decreases wind power by depleting natural resources.

• Wind energy has no effect on wind power.

• Wind energy negatively impacts wind power by causing pollution.

How do winds redistribute energy around Earth?

• By moving warm air from the equator to the poles and cold air from the poles to the equator

• By moving warm air from the poles to the equator and cold air from the equator to the poles

• By moving warm air from the equator to the equator and cold air from the poles to the poles

• By moving warm air from the poles to the poles and cold air from the equator to the equator
