What is the symbol for a cold front?
A blue line with spikes
A red line with half circles
Warm Front

What is false?
A cold and dry air mass
What is a continental polar air mass?
Dry conditions with cooler, dense air that sinks to the surface.

What front is a purple line with alternating purple triangles and half-circles?
An Occluded Front
The symbol for a stationary front

On a weather map, these lines help to identify patterns in air pressures.
What are isobars?

What is a continental tropical air mass?

This front is associated with severe weather.

What is a maritime polar air mass?

What is a stationary front?
This type of air mass forms over the ocean, has warm temperatures, and has brings wet air with lots of moisture.
What is a maritime tropical air mass?
When a warm, humid air mass collides with a dry, cold air mass, this develops.
