As altitude _________, air pressure ____________
Increases, decreases
You will have a lot of storms for days with stationary front true/false
True

Decompression sickness
At each point on an isobar, the pressure is ___________
The exact same
Warm air rises and cold air sinks. Why?
Because of its density
Lines on a map that show the air pressure
Isobars

What can be said about the weather in Denver?
Thunderstorms, snowing, cold, low pressure system
what front over powers which front to create a thunderstorm
cold warm
What is an occluded front?

What’s the difference between a wind vane and a compass rose
The wind vane measures wind direction as N,S, E, W and the compass rose is used specifically on maps
Why doesn’t a table crush from air pressure?
Because Air pressure is pushing against the table from all directions, keeping it balanced
Why are warm and cold fronts so different
Because of the density and temperature
