WIND

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

What causes wind?

• differences in air pressure

• differences in gravity

• difference in oxygen

• differences in the thermosphere

What is the main cause of land breezes?

• The gravitational pull of the moon

• The Coriolis effect

• The rotation of the Earth

• The difference in temperature between land and sea

Air at the poles is colder and denser so it_______________.

• rises

• circulates

• stagnates

• sinks

Which is NOT a characteristic of local winds?

• They occur within a small area.
• Land and sea breezes are examples.
• They blow over short distances.
• They blow steadily over long distances.

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.

What is responsible for warming the Earth’s surface and creating wind?

• The Moon
• Earth's interior (inside)
• Coriolis effect
• The Sun

How does the air move in a land breeze?

• From east to west
• From west to east
• From the land to the ocean
• From the ocean to the land

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.

Which factor does NOT influence the direction of wind?

• Earth's rotation

• Air pressure differences

• Temperature differences

• Humidity levels
