Air Pressure & Wind (from the slide deck)

What is air pressure?

• The speed of air particles hitting a surface

• The force exerted on you by the weight of tiny particles of air

• The temperature of the air around us

• The humidity level of the atmosphere

Approximately how much air pressure are you under right now?

• 500 lbs. of air

• 1000 lbs. of air

• 1500 lbs. of air

• 2000 lbs. of air

What is said about air when it's compressed?

• It is said to be "under low pressure"

• It is said to be "under moderate pressure"

• It is said to be "under high pressure"

• It is said to be "under no pressure"

According to the diagram, where is the air pressure higher?

• At the peak of Mt. Everest

• At sea level

• It is highest at 5000 ft above sea level

• Air pressure is the same at all altitudes
