Warm air is Warm air is less less dense. dense.

Another name for Another name for elevation is________.elevation is________.

AltitudeAltitude

The higher the altitude the The higher the altitude the lessless the air pressure 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, themore weight is pushing on your head!

This also means that the higher youraltitude, the less oxygen there will beto breathe!

(This is why people take oxygen tankswhen climbing Mt. Everest)

So... why do our ears and bags of chipspop when going up a hill?

It is because we are used to gettingpushed 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...
