The Highs and Lows of Air Pressure
Explanation:
Standing on the ground and looking up, you are looking through the atmosphere. It might not look like anything is there, especially if there are no clouds in the sky. But what you don’t see is air – lots of it. We live at the bottom of the atmosphere, and the weight of all the air above us is called air pressure. Above every square inch on the surface of the Earth is 14.7 pounds of air.
Air near the surface flows down and away in a high pressure system (left) and air flows up and together at a low pressure system (right).
