The correct options are
A Variation in temperature at different locations.
C Variation in heights from the sea level.
D Density of air.
The pressure exerted by the weight of the air is called the atmospheric pressure (P).
P=ρgh
According to the formula, we can say that it changes with the density of the air and height from the surface to the atmosphere.
The density of the air decreases as the temperature increases at different locations and vice-versa.
