EARTH'S ATMOSPHERE
LAYERS OF THE ATMOSPHERE
AIR QUALITY
AIR PRESSURE
MISC.
100
the most abundant gas in the atmosphere
nitrogen
100
the layer where weather is found
troposphere
100
Causing the hole in the ozone layer
CFC's
100
Why doesn't air pressure crush you
Because air molecules are pushing up in all directions
100
amount of mass in a given volume is this
density
200
the gas that makes up about 21% of the atmosphere
oxygen
200
where the ozone layer is found
stratosphere
200
Harmful substances in air, water, or soil
pollutants
200
instrument that measures air pressure
barometer
200
this is the distance above sea level
altitude
300
excess of this gas contributes to global warming
carbon dioxide
300
the "hot layer" of the atmosphere
thermosphere
300
1/2 of pollutants come from this source
cars
300
this happens to air pressure as altitude increases
decreases
300
this is also known as Northern lights
aurora borealis
400
Envelope of gases that surrounds the Earth
atmosphere
400
the layer of electrically charged particles
ionosphere
400
fog or haze combined with smoke and other atmospheric pollutants
smog
400
as the density of air increases, the air pressure does this
decreases
400
this is made up of 3 atoms of oxygen
ozone
500
condition of the earth's atmosphere at a particular time and place
weather
500
the thickest (most kilometers) layer of the atmosphere
thermosphere
500
Forms when nitrogen oxides & sulfur oxides (produced from burning fossil fuels) combine w/water in the air
acid rain
500
Because air has mass it also has
density & pressure
500
gaseous form of H2O
water vapor
