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

Using the windchill factor table, what is the windchill factor when the wind speed is 20 mph and the temperature is 30°F?

• The question has a diagram associated with it. The diagram has been stored separately.

• 15°F

• 25°F

• 35°F

Will the windchill factor be greater or less if the wind speed increases to 25 mph?

• Greater

• Less

• No change

• Cannot be determined

What is an anemometer used for?

During the day, where does the air move from and to in a sea breeze?

• The air moves from the sea to the land during a sea breeze.

• The air moves from the land to the sea during a sea breeze.

• The air moves from the sea to the mountains during a sea breeze.

• The air moves from the mountains to the land during a sea breeze.
