How can high altitudes make you short of breath?
The air is less dense which means the air that you breath has fewer oxygen molecules.
What causes brilliant light displays in the sky called auroras?
Particles from the sun strike atoms in the ionosphere.
What is the greenhouse effect?
The process by which the gases in air hold heat in Earth's atmosphere.
Most differences in air pressure are caused by what?
Unequal heating of the atmosphere.
