Question

the image shows a diagram explaining a concept. which concept does the diagram show? temperature altitude air density air pressure

Explanation:

Air pressure is the force exerted by the weight of air. The diagram shows a column of air with gravitational force acting on it, which is related to the concept of air pressure. Temperature is related to the average kinetic energy of particles. Altitude is the height above a reference level. Air density is mass per unit volume. The key here is the gravitational force on the air column and the mention of pressure at the surface.

Answer:

air pressure
