Question

The image shows a diagram explaining a concept.

Earth and its atmosphere. Gravitational force is pulling down on a 1 meter square air column with mass equals 10 superscript 4 kilograms. 1 atmosphere pressure at surface of the Earth.

Which concept does the diagram show?

temperature
altitude
air density
air pressure

Answer 1

The diagram you described is illustrating the concept of **air pressure**. It shows how gravitational force affects an air column, resulting in the pressure exerted by the weight of the air above per unit area (1 meter square in this case). The reference to 1 atmosphere of pressure at the surface of the Earth further indicates that it relates specifically to air pressure.
