What is continental polar?
200
The type of cloud that forms a layer across the sky.
What is stratus?
200
The type of precipitation that can start as a liquid or a solid, but falls to the ground as a liquid.
What is rain?
200
The type of front where cold air quickly pushes warmer air out of the way.
What is a cold front?
300
The amount of water vapor in the air compared to what the air can hold at that temperature. It is measured with with either a sling psychrometer or a hygrometer.

What is cirrus?
300
The type of precipitation that forms when liquid water freezes on the way down.
What is sleet?
300
The type of front where neither warm nor cold air pushes the other out of the way.
What is a stationary front?
400
The temperature at which the water vapor in the air begins to condense.

What is cumulonimbus?
400
The type of precipitation that forms when very cold liquid water freezes on to a cold surface.
What is freezing rain?
400
The type of front where a cold air mass catches up to another cold front, trapping warmer air in between.
What is an occluded front?
500
The measure of the total amount of water vapor in the air.
What is humidity?

What is the dew point?
500
The type of precipitation that forms when an ice pellet in a thunderstorm cloud rises and falls in the cloud, forming additional layers of ice.
What is hail?
500
