Question

Which statement accurately describes the relationship between air pressure air density or altitude

Answer 1

Answer: Denser air exerts more pressure than less dense air.

Explanation:

Air pressure depends on the height of the air column above a point. It also depends on the density of air.

Thus, at higher altitude, air density and air pressure is low. At lower altitude, the air pressure is high.

The region having greater density of air would have greater air pressure than the region having less dense air.

Answer 2

The answer is; dense air exerts more pressure than less dense air

Pressure is due to the weight of the above column of the substance which is a force resulting from its weight that is the product of its mass and gravitational pull. The denser the air and the grater the column, the larger its mass and hence the more the pressure it exerts.
