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

Wind belts are always named according to...

• how strong they are
• what temperature they are
• where they blow to
• where they come from

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

• the moon
• the sun
• the Earth's surface
• the rotation of the Earth

Which term is best described as the movement of air from land to sea?

• global winds
• sea breeze
• land breeze
• local winds
