• What is the function of the atmosphere?
• The atmosphere is layers of gasses that surround the Earth.
• Earth’s atmosphere has two main functions: 1st it contains gas like O2 that we need to live and 2nd it traps heat so the water on the planet remains liquid.

• How does altitude affect air pressure and density?
• Air has mass, density, and pressure.
• The distance above sea level. (the surface of the ocean)
• The higher the altitude the lower the air pressure and denisty
• The lower the altitude the greater the air pressure and density.
