As altitude increases, air pressure decreases. Why?

Back

Air pressure decreases because gravity pulls air molecules to the Earth's surface creating air pressure. As you go away from Earth's surface, there are less molecules pushing down from above

Front

How does Atmospheric Composition affect Air Temperature?

Back

Temperature changes in the atmosphere occur because some layers have gases that absorb more solar energy than others
