3.1 Wind

What causes wind to blow?

• Differences in longitude 
• Shock waves from clouds 
• Differences in air temperature and pressure 
• The rotation of the earth

What causes warm air to rise?

• the fact that it's less dense than cold air 
• The fact that it weighs more than cold air 
• The fact that it has higher pressure than cold
• the fact that its more dense than cold air 

How do differences in air pressure affect the movement of air?

• Air always moves from areas of high pressure to areas of low pressure.
• Air always moves from areas of low altitudes to high altitudes.
• Air always moves from areas of low pressure to areas of high pressure.
• Air always moves from east to west.

height above sea level (above the Earth's surface)

• atmosphere

• sea level

• air pressure

• altitude

Which of these MOST likely causes winds to blow on Earth?

• Earth spins quickly, causing air to blow around.
• The gravity of Earth and the Moon push and pull the air.
• Warm air rises and cool air falls toward Earth's surface.
• Ocean waves push air onto the shore and across Earth's surface.
