Question

1.How does air pressure vary with height?

​

Answer 1

$\huge\underline\mathfrak{\red{A}\pink{N}\purple{S}\green{W}\red{E}\blue{R}}$

Pressure with Height: pressure decreases with increasing altitude. 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.

Answer 2

Answer:

Altitude variation

Pressure on Earth varies with the altitude of the surface; so air pressure on mountains is usually lower than air pressure at sea level. Pressure varies smoothly from the Earth's surface to the top of the mesosphere. ... As altitude increases, atmospheric pressure decreases.
