Question

What effect does altitude have on atmospheric pressure

Answer 1

Answer:

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. 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.

Answer 2

Answer:

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.The relationship between altitude and atmospheric pressure. As the elevation increases from sea level the atmospheric pressure decreases. The range of the earth’s atmosphere is 101 kPa at sea level to near 0 kPa at 30,000 m.
