ATMOSPHERE

What elements makes up the atmosphere?

• carbon dioxide, helium, neon, and krypton
• hydrogen, methane, carbon monoxide, and sulfur dioxide
• water vapor, radon, xenon, and ozone
• nitrogen, oxygen, argon, and other trace gases

These are particles of dust, smoke, salt crystals and tiny solid/liquid particles

• aerosols
• planets
• molecules
• atoms

Atmosphere exerts pressure that decreases with increasing altitude above the surface.

The higher the altitude, the lower the pressure.
