Global Patterns

What is wind?

• Moving air caused by different air temperatures and densities.

• Moving water caused by different water temperatures and densities.

• Moving air caused by the rotation of the Earth.

• Moving water caused by the rotation of the Earth.

What is the Coriolis Effect?

• The effect of Earth's rotation on wind and ocean currents.

• The effect of Earth's rotation on temperature and precipitation.

• The effect of Earth's rotation on air pressure and humidity.

• The effect of Earth's rotation on wind direction and speed.

What causes global winds to turn to the right in the Northern Hemisphere and to the left in the Southern Hemisphere?

• The rotation of the Earth.

• The temperature difference between the Northern and Southern Hemispheres.

• The density difference between the Northern and Southern Hemispheres.

• The pressure difference between the Northern and Southern Hemispheres.

What are the major global wind belts?

• Trade winds, polar easterlies, and prevailing westerlies.

• Jet streams, polar easterlies, and prevailing westerlies.

• Trade winds, jet streams, and prevailing westerlies.

• Trade winds, polar easterlies, and jet streams.

What can a shift in global wind belts cause?

• Changes in weather patterns.

• Changes in ocean currents.

• Changes in air pressure.

• Changes in humidity and precipitation.

What are the high-speed winds that generally blow from west to east called?

• Jet streams.

• Trade winds.

• Polar easterlies.

• Prevailing westerlies.

How do forecasters use the jet stream to predict weather?

• They track its position to predict temperature and precipitation.

• They track its speed to predict temperature and precipitation.

• They track its direction to predict temperature and precipitation.

• They track its altitude to predict temperature and precipitation.

What does a southward shift of the polar jet stream usually indicate?

• Colder temperatures and snowy conditions in areas north of the jet stream.

• Warmer temperatures and sunny conditions in areas north of the jet stream.

• Colder temperatures and snowy conditions in areas south of the jet stream.

• Warmer temperatures and sunny conditions in areas south of the jet stream.

What does a northward shift of the jet stream usually indicate?

• Warmer temperatures and sunny conditions in areas south of the jet stream.

• Colder temperatures and snowy conditions in areas south of the jet stream.

• Warmer temperatures and sunny conditions in areas north of the jet stream.

• Colder temperatures and snowy conditions in areas north of the jet stream.

What is the difference between weather and climate?

• Weather refers to short-term atmospheric conditions, while climate refers to long-term patterns of weather.

• Weather refers to long-term patterns of weather, while climate refers to short-term atmospheric conditions.

• Weather refers to temperature, while climate refers to precipitation.

• Weather refers to precipitation, while climate refers to temperature.
