EARTH'S ATMOSPHERE
the most abundant gas in the atmosphere
What is nitrogen?
the layer where weather is found
What is troposphere?
Combination of light, pollution, and O3
smog
this layer protects us from meteoroids
What is the mesosphere?
high level, wispy, and composed of ice crystals
What is Cirrus?
the gas that makes up about 21% of the atmosphere
What is oxygen?
where the ozone layer is found
What is stratosphere
instrument that measures air pressure
What is a barometer?
storm clouds, extend through ALL layers
this gas is good when it is in the stratosphere but bad when it is in the lower troposphere, made of 3 atoms of oxygen
What is ozone?
the "hot layer" of the atmosphere
What is thermosphere?
Protects us from harmful UV rays
What is the ozone layer?
this happens to air pressure as altitude increases
What is decreases?
this is also known as Northern lights
What is aurora borealis?
this varies in the atmosphere and cycled on Earth, gaseous form of H2O
What is water vapor?
the layer of electrically charged particles
What is ionosphere?
these gases can allow us to live on earth but when there are more of them planets warm
What are green house gases?
the density of air does what as you move away from the troposphere
What is decreases or spreads out?
fluffy clouds, dense, made of water droplets
What is Cumulus?
circular air patterns caused by warm air and cold air interacting
What is convection currents?
the thickest layer of the atmosphere
What is thermosphere
Forms when nitrogen oxides & sulfur oxides combine w/water in the air
acid rain
GPS satellites are found in this layer
What is the exosphere?
low level clouds, layers like a blanket, water droplets
What is stratus?
