Wind

What causes wind?

• differences in air pressure

• differences in gravity

• difference in oxygen

• differences in the thermosphere

What causes differences in air pressure?

• even heating of the Earth

• Even cooling of the earth

• uneven heating of the earth

• global warming

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 to a colder area in the atmosphere.
• Wind is the movement of air from areas of high pressure to areas of low pressure.
• Wind is the movement of air pushed around and bouncing off Earth's surface.

Why does warm air rise?

• Warm air is more dense than cooler air.
• Warm air has more pressure than cooler air.
• Warm air is less dense than cooler air.
• Warm air has a higher dew point than cooler air.

Air is warmer and less dense at the equator because the equator receives more____________________.

• wind

• solar radiation

• air pressure

• condensation

In the Northern Hemisphere, winds traveling north appear to curve east because of the:

• trade winds

• convection currents

• Coriolis effect

• polar easterlies

The Coriolis effect is the curving of wind across Earth. What causes winds to curve?

• Earth's revolution
• Earth's magnetic field
• Earth's rotation
• Earth's gravitational pull

Use the diagram to determine which statement is correct.

• The air at location 3 is more dense than the air at location 6.
• The air at location 2 is rushing in to take the place of the colder air at location 3.
• Location 1 heats up and cools down slower than location 7.
• High pressure air at location 2 is taking the place of the low pressure air at location 3.

In which direction do prevailing westerlies flow?

• from east to west
• from west to east
• from north to south
• from south to north

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

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