Air and Winds Pre Test

Moving air caused by differences in air pressure is known as

• wind
• humidity
• precipitation
• temperature
• Option 5

Convection currents in Earth's oceans and atmosphere are caused by

• the distance of the Equator from the poles.
• Earth's four seasons.
• the uneven heating of Earth.
• the amount of precipitation on Earth.

Choose the correct statement.

• Warm air is less dense, has lower air pressure, and rises. Cold air is more dense, has higher air pressure, and sinks.
• Warm air is more dense, has higher air pressure, and sinks. Cold air is less dense, has lower air pressure, and rises.
• Warm air and cold air have the same density and air pressure and can both rise and sink.
• Warm air has no density and has no air pressure. Cold air has density, but has no air pressure.

Trade winds, westerlies, and polar easterlies are

• winds that travel in straight pathways.
• winds that generally move over short distances.
• large-scale winds systems called global winds that travel long distances.
• winds that only occur during a leap year.

An area where air molecules are more dense in sinking cool air is a

• low pressure zone.
• no pressure zone.
• high pressure zone.
• no parking zone.

The curving of global winds and ocean currents due to Earth's rotation is called the

• Coriolis effect.
• Greenhouse effect.
• Global warming effect.
• No Wind effect.

Winds that can blow in any direction and travel short distances are known as

• global winds.
• northern gusts.
• jet streams.
• local winds.

Choose the correct pairing of calm regions.

• Polar Easterlies and Doldrums.
• Westerlies and Trade Winds.
• Horse Latitudes and Doldrums.
• Horse Latitudes and Westerlies.
