Answer 1

High altitude and low pressure

at high altitude, atmospheric pressure is lower than that at sea level. this is due to two competing physical effects: gravity, which causes the air to be as close as possible to to the ground ; and the heat content of of the air, which causes the molecules to bounce off each other and expand.
