Global Winds

In which direction do prevailing westerlies flow?

• from east to west

• from west to east

• from north to south

• from south to north

Match the following winds to their latitude ranges:

• 30° to 0°

• westerlies

• 30° to 60°

• trade winds

• 90° to 60°

• polar easterlies

The tropical winds running from 0 to 30 degrees latitude are called:

• subtropical westerlies
• polar westerlies
• trade winds
• polar winds

What is the initial source for global winds and convection in the atmosphere?

• heat from the Earth's core

• the rotation of the Earth

• Moon's gravity

• unequal heating of the Earth by the sun

Cold winds that blow from east to west between latitude lines 60°N and the North Pole and 60°S and the South Pole.

• Prevailing westerlies
• Trade winds
• Horse latitudes
• Polar easterlies

Steady winds that flow from east to west between 30°N latitude and the equator and 30°S latitude and the equator.

• Prevailing westerlies
• Horse latitudes
• Trade winds
• Polar easterlies

Why does warm air rise?

• Warm air is more dense than cooler air.

• Warm air is less dense than cooler air.

• Warm air has more pressure than cooler air.

• Warm air has a higher dew point than cooler air.

Where does the initial source of energy come from that creates winds?

• the moon

• the sun

• the rotation of the Earth

Match the Global Winds to their correct letter:

• Polar Easterlies

• Label C

• Westerlies

• Label B

• Trade Wind

• Label A

Which statement correctly defines wind?

• Wind is the movement of air from areas of low pressure to areas of high pressure

• Wind is the movement of air from areas of high pressure to areas of low pressure.

• Wind is the movement of air to a colder area in the atmosphere.

• Wind is the movement of air pushed around and bouncing off Earth's surface.
