Air pressure increases above 0.6 bar at an altitude less than 7 km.c. At the top of Mt. Everest, air pressure is less than 0.4 bar.d. Air pressure increases linearly with altitude.

Answer:

C. At the top of My Everest, air pressure is less than 0.4 bars

Explanation:

The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels. For example, there are fewer molecules above the 50 km surface than are found above the 12 km surface, which is why the pressure is less at 50 km.
