Anything Goes
100
The current condition of the Earth's atmosphere.
What is weather
100
Air Pressure is measure with this instrument.
What is a barometer?
100
The layer closest to the surface where weather occurs.
What is the troposphere?
100
Any harmful substance in the air, water or soil.
What is a pollutant?
100
The two gases that make up roughly 99% of the atmosphere.
What are nitrogen and oxygen?
200
A thin layer of gases that surround the Earth.
What is the atmosphere?
200
As you climb a mountain air pressure does this.
What is goes down/decreases?
200
The layer of the atmosphere known for containing the ozone layer.
What is the stratosphere?
200
Pollution from fire, dust storms and volcanoes.
What are examples of natural pollution?
200
Pressure pushes equally in all directions.
What is the reason we don't look like Flat Stanley?
300
The most abundant gas in the atmosphere.
What is nitrogen?
300
Air has this because it also has volume and density.
What is mass?
300
The layer that protects us from meteoroids.
What is the mesosphere?
300
Burning fossil fuels such as coal, oil, gasoline, and diesel fuel.
What is the biggest source of air pollution?
300
The reason why the density of air molecules is greater closer to the surface of the Earth.
What is gravity?
400
The amount of this gas varies in the atmosphere and is the basis of an important cycle.
What is water vapor?
400
In the column of air above you, density is greatest here.
What is closest to the surface?
400
The layer that produces the Aurora Borealis in the Northern Hemisphere when its atoms interact with energy from the sun. (charged atoms are called ions)
What is the ionosphere (within the thermosphere)?
400
The government agency that monitors air quality in the U.S.
What is the EPA (Environmental Protection Agency)?
400
When you visit the mountains this also decreases along with pressure and temperature.
What is density?
500
Three oxygen atoms make up this important molecule.
What is ozone?
500
Two units of measuring air pressure.
What are inches and millibars.
500
The layers of the atmosphere are determined by this.
What is temperature?
500
Two types of air pollution caused by burning fossil fuels.
What are photochemical smog and acid rain.
500
The two layers of the atmosphere that have increasing temperatures as you go up.
What are the stratosphere and the thermosphere?
