How does the density of air in a deep mine compare with the air density at Earth’s surface?
Step 1 of 3
Air is compressible it gets denser. this means that the air at the top of the atmosphere is less dense than the air lower down in the atmosphere because the weight of the air above squishes the air below it. If you go up in a lift in a tall building, your ears 'pop' because the air at the top is less dense than the air was at the bottom. As you go down a mine there is more air above you than at the top of the mine shaft so the air gets progressively denser the deeper you go. At the bottom of the mine the air is,therefore, more dense than at the earth's surface.
