What is an air mass?
The boundary where two different air masses meet.
What is a front?
This instrument measures air temperature.
What is a thermometer?
Scientists who study the weather.
What are meteorologists?
Air masses are classified based on their temperature and this characteristic.
What is humidity?
This type of front forms when a warm air mass rises over a cold air mass.
What is a warm front?
Lines on a map that connect points that have the same temperature at a given time or on average over a given period.
What are isotherms?
The movement of air from an area of high pressure to an area of low pressure.
What is wind?
This type of air mass forms over warm ocean waters and brings warm, moist air.

This type of air mass brings dry air from tropical regions.
What is continental tropical?
This happens when a cold front passes through an area.
What are cooler temperatures and possible storms?
This causes the rotation of winds in the atmosphere.
What is the Coriolis Effect?
The amount of water vapor present in the air.
