#2. There's different gasses in our atmosphere nitrogen, oxygen, and other gasses. But there's one gas that is 78% of the atmosphere and that's Nitrogen. Oxygen 21%. The other gasses are 1%
#3. The atmosphere protects us from the sun's UV-B radiation. But keeps some of the heat inside the atmosphere.
#4. The higher you go the air becomes thinner and the pressure decreases.
#5 Without the atmosphere the Earth would be too hot. It would be too hot because the sun radiation would be too hot.
