The air pressure at Mt. Everest is much less than the air pressure at sea level because air pressure decreases with altitude. This is because at higher altitudes, there is less air pushing down from above. An addition, gravity is weaker, as it is farther from Earth's center. Because of this, air molecules can spread out more at higher altitudes, resulting in decreasing air density.
