Air pressure exerts force in all directions. This means that at sea level, air pressure acts equally in every direction, including down towards the surface of the Earth, up towards higher altitudes, and sideways. This characteristic is due to the random motion of air molecules, which collide with surfaces and each other, transmitting force in all directions.

back up towards the top of the force of weight of the air
