Which factor increases as a result of increasing altitude? air pressure air density height of sea level space between gas molecules

The correct answer is: space between gas molecules.

Altitude is most often defined as height above sea level. It is a vertical distance measurement. As altitude increase the air density decrease because the gravity is weaker. As a result air molecule are more distant, space between them is increased. Also, at high altitude the pressure is low ( less air pressing down from above).
