describe how the amount of air changes as you travel up through earths atmosphere. Help me plz if i dont do this im in troble by my teacher.

As you travel further from the Earth's surface, the atmosphere changes.  The closer to the Earth's surface, the greater the weight (or force) of the atmosphere because air near the surface has ALL air above it pushing down on it. As an airplane travels higher into the atmosphere, air pressure decreases.
