Wind and Wind Direction

What causes wind?

• unequal air pressure

• the spin of the earth

• the gravity from the moon

• earth's gravity

What causes unequal air pressure to occur?

• unequal heating of earth's surface

• coriolis effect

• global wind

• local wind

what is global wind?

• wind that travels long distances in steady patterns

• wind that travels short distances

• wind that changes direction constasnty

• the coriolis effect

Why do global winds appear to curve

• Coriolis effect

• The earth's orbit

• The moods gravity

• ocean currents

The coriolis effect is only noticeable on winds that travel long distance.

• True

• False

Sinking air

• cold air, high pressure

• warm air, low pressure

• hot dry air

• cold damp air.

Rising air

• Warm air, low pressure

• cold air, high pressure

• Warm air, high pressure

• cold air, low pressure

What kind of climate is found at regions of high pressure

• dry

• wet

• warm

• extreme cold.

What type of climate is found at low pressure wind belts.

• cloudy/wet

• dry and clear

• wet and cold

• dry and hot

How does the polar jet stream affect our weather?

• It can pull cold air down from canada or pull warm air up from the south.

• It pulls moisture from the ocean

• It pulls dry air from mexico

• It does not affect our weather.
