Question

Which factor causes atmospheric pressure?
A. Sizes and shapes of clouds
B. Air currents in the atmosphere over the ocean
C. Altitude above sea level
D. Weight of the atmosphere above a surface

Answer 1

The cause of Atmospheric Pressure is D, Weight of the atmosphere above a surface. This is because when there is weight in gases in the atmosphere, like Greenhouse Gases, it can cause pressure in the atmosphere.

Answer 2

Answer:

D. Weight of the atmosphere above a surface

Explanation:

As we know that pressure is defined as the ratio of Force and area.

it is given as

$P = \frac{Force}{Area}$

Now we know that atmospheric pressure at any point where we need to find is due to some force above that point. Here this force is due to weight of the air or gases above that point where we need to find the atmospheric pressure

we can write it as

$P = \frac{mg}{A}$

so it directly depends on the weight of atmosphere above the surface
