Warm air is less dense.

Another name for elevation is________. Altitude

The higher the altitude the less the air pressure

There are two main factors that decide what air pressure we feel. #1 = Altitude: how high up in the atmosphere you are.

Oxygen is heavier than Nitrogen, so it sinks to the bottom of the atmosphere. That means that the lower you are, the more weight is pushing on your head!

This also means that the higher your altitude, the less oxygen there will be to breathe! (This is why people take oxygen tanks when climbing Mt. Everest)

So... why do our ears and bags of chips pop when going up a hill? It is because we are used to getting pushed on by the pressure of the air.

High Pressure (cold)Low Pressure (warm) To equalize the amount of pressure, oxygen will move to evenly distribute it. We can see and feel the oxygen moving...

Study this quiz, your notes and review and you will do great!
