Atmospheric pressure depends on .......

• mass

• density

• altitude

• magnitude

What happens to the amount of oxygen molecules as altitude increases?

• fewer molecules

• more molecules

• same amount of molecules

• nothing happens to the molecules

Describe the relationship between altitude and air pressure:

Answer explanation

Higher altitude leads to lower air pressure and lower altitude leads to higher air pressure. This is an inverse relationship.

As altitude increases, the pressure of the Earth's atmosphere ​ (a)   .
