100

The natural process where water is recycled throughout the planet.

What is the water cycle?

100

The boundary where two air masses meet and produce weather.

What is a front?

100

The layer of the atmosphere that we live in.

What is the troposphere?

100

Characterized by heavy winds, rain, and lightning.

What is a thunderstorm?

100

Created when water vapor condenses in the upper atmosphere.

What is a cloud?

200

When liquid water is converted to vapor.

What is evaporation?
200

On a weather map, represented by a large red L.

What is a low pressure system?

200

The spectacular Aurora Borealis (Northern Lights) occurs in this layer.

What is the thermosphere?

200

This type of storm is a frequent occurrence in the Midwestern United States in early spring.

What is a tornado?

200

These clouds are high up and composed primarily of ice.

What is a cirrus cloud?

300

When water falls back to the surface of the Earth in various forms.

What is precipitation?

300

Represented by alternating red semicircles and blue triangles.

What is a stationary front?

300

Meteors burn up in this layer.

What is the mesosphere?

300

Large, cyclonic tropical storms that occur over warm ocean waters.

What is a hurricane?

300

The classic puffy cloud that signifies neutral weather.

What is a cumulus cloud?

400

The method of transferring heat through the movement of a fluid, such as water or air.

What is convection?

400

Occurs when a cold air mass replaces a warm air mass.

What is a cold front?

400

The layer that is closest to outer space.

What is the exosphere?

400

Large rotating area of high pressure, and brings fair weather.

What is an anticyclone?

400

These clouds are associated with warm fronts and often bring rain.

What is a stratus cloud?

500

When water vapor releases heat and converts back to a liquid.

What is condensation?
500

Sometimes preceded by fog, this front typically has lower pressure than a cold front and brings rain.

What is a warm front?

500

The layer where temperature increases, and where certain military jets fly.

What is the stratosphere?

500

These are the hearts of all storms, and are created by the rising and falling of air.

What is a convection cell?

500

These types of clouds occur in the stratosphere over high latitudes, and signify ozone destruction.
