should show east to west
What causes the earth to have seasons?
The tilt of the earth on its axis.

what happens to the warm air at the equator
rises
Which layer of the atmosphere is where weather, the GH effect, etc. occurs?

Nitrogen
Oxygen
Argon
Explain the greenhouse effect and how humans are negatively impacting it.
Solar radiation is reflected off the earth and trapped by the GHGs. Humans are adding GHGs - increasing the greenhouse effect.
around 30 degrees the air cools what would happen
What happened at the Montreal Protocol?
Required a phase out of CFCs.

Right, Left
What is GWP? Which pollutant that we discussed has the highest? The lowest?
Global warming potential, CFCs, CO2
Why might el nino be good for the us
more rainfall in the southern states= more crops
"Good" ozone is located in the _________ while "bad" ozone is located in the __________.
Stratosphere, Troposphere
How is climate change impacting wind circulation patterns?
Hadley cells are widening and the jet stream is changing course --> Impacts temperature/precipitation patterns.
the seasons
What was the key takeaway from the Clean Air Act?
Set air quality standards that states have to follow, set in place the 6 criteria air pollutants, reduced the amount of lead in the air.
Warmer water near peru is associated with which phenomenon?

Describe the rain shadow effect.
As air moves up the mountain it cools, holds less water, and rains. As it moves over and down the mountain it warms, holds more water, and sucks up the moisture.
Explain how melting sea ice & a warming world demonstrate and positive feedback loop
Melting ice = lower albedo = more heat absorbed = warmer water/planet = melting ice
