a huge body of air that has similar temperature, humidity, and air pressure.
What is an air mass?
100
A violent disturbance in the atmosphere. Involves sudden changes in air pressure which causes rapid air movements.
What is a storm?
100
a thin glass tube with a bulb on one end that contains liquid, measures temperature

elevation above sea level
What is altitude?
100
process by which molecules of water vapor in the air become liquid water
What is Condensation?

A sudden discharge of energy charge between the cloud and the ground.
What is lightening?
200
measures wind speed
What is an anemometer?
200
the region between 66.5 to 90 degrees north and south latitudes and the poles; the sun's rays strike at a very small angle in the polar zone.
What is the polar zone?

Cold air mass runs into a less dense warmer air mass. Causes cloud formation and potentially violent weather including thunder storms.
What is a cold front?
300
horizontal movement of air from an area of high pressure to an area of low pressure
What is wind?

What are thunder storms?
500
an instrument that is used to measure air pressure
What is a barometer?
500
an increase in the average temperature of the earth's atmosphere (especially a sustained increase that causes climatic changes). It is caused by human actions right now.
What is global warming?
