What is an air mass?
200
White puffy clouds formed from water droplets.
What are cumulus clouds?
200
Lines on a weather map that connect areas with the same air pressure and humidity.
What are isobars?
200
Water vapor that turns directly into solid crystals at freezing temperatures.
What is snow?
200
A prediction of what the weather will be over the next few days.
What is a forecast?
200
A meeting place between air masses.
What is a front?
300

What are cirrus clouds?
300
This is represented by a red line with half-circles.
What is a warm front?

400
Layered blanket-like clouds that are found at low altitudes.
What are stratus clouds?
400
A system that brings warm, stormy weather.
What is a low pressure system?
400
Precipitation that is formed when water droplets freeze, fall out of the cloud, are bounced back up into the cloud during stormy weather where they refreeze over and over again before falling to the ground.
What is hail?
400
This high-altitude global wind blows from west to east and moves weather from west to east.
