Wind Formation

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

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

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

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 at the poles is colder and denser so it_______________.

• rises

• circulates

• stagnates

• sinks

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

Cold air exerts _____________ pressure than warm air.

• the same
• less
• more 
• impossible to tell

Which term best describes how the earth's atmosphere is heated?

• Spirally
• Unevenly
• Circularly
• Kinetically

When Earth's rotation causes the wind to curve 

• cloudy 
• Coriolis effect
• high pressure
• low pressure 

When heat rises cools then sinks 

• high pressure 
• convection current 
• low pressure 
• stratospheric pressure
