![]() ![]() As less dense air weighs less, it produces lower air pressure, which is why it can be difficult to breathe on top of a tall mountain. Altitude: The higher you are above sea level, the less dense the air is.This phenomenon is why areas near the equator, which are hot, generally have low air pressure, and areas near the North and South Poles, which are cold, have high air pressure. This shrinking causes the air to become denser, which leads to higher pressure. When air gets colder, on the other hand, it shrinks. This expansion causes the density of the air to decrease, which results in lower pressure. Temperature: As air gets warmer, it expands.The reason we can still move our bodies freely is because the air is exerting pressure on us in all directions, and the reason we aren’t crushed is because the air pressure inside our bodies is the same.Air pressure is determined by the following three factors: At sea level, air pressure is generally 14.7 psi (pounds per square inch), which means that 14.7 pounds are pressing down on every square inch of our bodies. The term “air pressure” is used in reference to the weight of air molecules pressing down on the earth. Click Here To Register For One Of Our Virtual Programs What Is Air Pressure? ![]()
