Air Pressure

What are the four causes for a change in air pressure?

1. Change in temperature 2. Change in elevation 3. Large object pushing air out of the way 4. Quickly moving air

What causes air pressure?

Gravity pulls the air molecules down on top of each other towards Earth.

Whats the relationship between temperature and air pressure?

When the temperature is higher, the air pressure is lower When the temperature is lower, the air pressure is higher

How does temperature affect air pressure? (think: how does temperature affect the movement of air molecules?)

Air molecules move quickly and spread out in warm temperatures, creating low pressure. Air molecules move slowly and squish together in cold temperatures, creating high pressure

In what direction do air molecules like to travel?

Always from high pressure areas to low pressure areas.

What tool is used to measure air pressure?

Barometer

What is density

How much mass is in a certain amount of space

What is pressure?

The amount of force pushing on an object,
