This front brings light rain and higher temperatures.
What is a warm front?
100
This is a violently spinning column of air.
What is a tornado?
100

Plant process, performed in early bacteria, that converted the first atmosphere's CO2 into O2.

What is the troposphere?

100
This process describes liquid water becoming ice.
What is freezing?
100
This type of pressure is shown with an "H" on a weather map.
What is High Pressure?
200
This front brings storms and lower temperatures.
What is a cold front?
200
This is a large, low-pressure system that forms in the Atlantic Ocean.
What is a hurricane?
200

This process drives all weather through rising warm, moist air and sinking cool air.

What is convection?

200
This process describes liquid water becoming vapor.
What is evaporation?
200
This type of pressure is shown with an "L" on a weather map.
What is Low Pressure?
300
This front doesn't move.
What is a stationary front?
300
This weather instrument measures wind speed.
What is an anemometer?
300

The atmosphere burns these up and vaporizes them, protecting life.

What are meteors?

300

This process describes water vapor becoming liquid on nuclei in the cold.

What is condensation?

300
This type of pressure is associated with clear weather.
What is High Pressure?
400
This front is a combination of three air masses.
What is an occluded front?
400
These clouds are associated with thunderstorms and tornadoes.
What are cumulonimbus clouds?
400

This process describes how pollutants, such as CO2 and methane, increase atmospheric temperatures.

What are global warming, climate change, or the greenhouse effect?

400
This is how water returns to the ocean from precipitation on the land.
What are Surface Runoff or Rivers?
400
This type of pressure is associated with cloudy or bad weather.
What is Low Pressure?
500
This type of front is produced by the cool band of Canadian air called the Jet Stream.
What is a cold front?
500
This word represents all forms of water that falls from the sky.
What is precipitation?
500
This atmospheric layer protects people from ultraviolet rays from the Sun.
What is the Ozone Layer?
500

Clouds form through this water process on nuclei.
