What is Make up Earth's atmosphere
300
Light interacts with nitrogen oxides, hydrocarbons, and other pollutants.
What is Photochemical smog
300
Two atmospheres that protect/make living easier on earth.
What is troposphere-weather makes it livable
Stratosphere- protects us with ozone and absorbs radiation
Mesosphere- keeps meteoroids from crashing into earth.
Thermosphere -bounces back radio waves and gives us heat.
400
Satellites orbit in this layer.
What is Exosphere
400
Is the layer of gases that surrounds the planet.
What is Atmosphere
400
Waves from ocean water contributing salt into the air, wind blowing particles of pollen into the air, forest fires, soil erosion, dust storms, and volcanoes erupting and spewing ash into the air.
What is Natural Pollution
400
large amounts of soot in the air that combined with water molecules.
What is London Smog

What is spreading out
500
Nitrogen and Oxygen molecules convert energy from the sun into heat in this atmosphere.
What is Thermosphere
500
3 characteristics air has.
What is Air has mass,it also has other properties including density and pressure.
500
Why does a climber need a oxygen mask?
What is Alitilude increase, air pressure and density decrease causing us to have trouble with respiration.
500
Farming (tilling the land), and construction/destruction of buildings.
What is Human Pollution
500
How do you drink with a straw
What is your mouth is closing the top so air pressure pushing down on the water pushes it up the straw.
