Explanation:

As Joe, a hiker, stands at the top of a hill on a trail above the ocean, Joe is at a higher altitude than if he was at the beach.

The body human can adjust when the body is placed at high altitude. At these high altitude, the percentage of oxygen available in the air at the atmosphere arround the body become which means there would be less oxygen for the body to breath in. As a result of this the blood accross all the lungs is in short of oxygen, this will now cause increase in the breathing Dept rate which means the air that Joe is breathing is less dense than the air at sea level.
