The (air) pressure was on today as Rick Crosslin, scientist in residence for MSD Wayne Township, joined us with a few experiments to demonstrate how air pressure in Earth’s atmosphere works.
Facts About Air Pressure In Our Atmosphere
- Air is made of matter: It takes up space and has mass
- Air is a mixture of gases (Nitrogen and Oxygen mostly) that has mass and can be squeezed.
- The push or squeeze of air is called air pressure.
- Our atmosphere has layers of air – with different pressure and temperature: (see liquid model)
- Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere
- We have high pressure and low-pressure areas of air on the surface.
- Sea level air pressure is 14.7 pounds per square inch (see atmosphere bar)
