Climate change is defined as a change in the average temperature over a period of at least
300 years
300,000 years
3 decades
3 millions years
Global warming can be misleading because
There is no proof that it is actually happening.
All areas of the Earth are not getting warmer every year.
It isn't Carbon Dioxide that is causing the temperature increase.
It isn't the greenhouse gases that are causing the heat to be trapped.
What are the main greenhouse gases?
carbon dioxide, oxygen, water vapor, nitrous oxide, methane
carbon dioxide, methane, nitrous oxide, water vapor, sulfur dioxide
methane, water vapor, carbon dioxide, oxygen
methane, water vapor, carbon dioxide, nitrous oxide
The oceans take in carbon from the atmosphere and over time it
will become stored deep in sediments building reservoirs of carbon
will all get taken in by phytoplankton and destroy the aquatic food chains
will settle at the top of the ocean
will form water vapor
Choose which answer(s) are possible effects of rapid atmosphere warming:
Increased hurricanes and typhoons
Increased diseases
Disastrous forest fires
Starvation of the poorest populations
What is the main reason sea levels are rising rapidly?
melting sea ice
increase of water vapor in atmosphere
melting land ice
increase in floods
What are the biggest source(s) of atmospheric methane?
deforestation
burning fossil fuels
melting permafrost
livestock
Gases in the Earth's troposphere retaining the infrared radiation and warming the Earth is referred to as:
Climate Change
Permafrost Melt
Ozone Depletion
Greenhouse Effect
Where does most nitrous oxide emissions come from?
fertilizers
permafrost
livestock
vehicles
What is the function of the Ozone Layer?
It protects the surface of the Earth from the ultraviolet radiation
It protects the Earth's surface from the infrared radiation
It decreases greenhouse emissions
It builds reservoirs of carbon
Which gas(es) caused the thinning of the Ozone?
CO2
CFC
CH4
CO
What did consumers primarily use this gas for that caused the thinning of the Ozone? Choose all that apply.
gasoline
coolants
aerosols
refrigerants
What are possible effect(s) of the thinning of the Ozone?
cataracts
skin cancer
increased sunburns
destroys phytoplankton
As the troposphere gets warmer, what does this do to the stratosphere? Check all that apply.
Warms the stratosphere
Cools the stratosphere
speeds the ozone repair
slows the ozone repair
If all of the chemicals causing ozone depletion are completely stopped being emitted into the atmosphere, how long will it take for the ozone to recover?
6 years
60 years
600 years
6000 years
Choose the elements that the gas CFC is composed of ? Click all that apply.
carbon
chlorine
fluorine
hydrogen
We have made progress with the depletion of the ozone by not using CFC's according to the Montreal Protocol. What are we doing that is slowing the progress of the ozone depletion down?
growing our populations
increasing our CFC use
human caused climate change
technology use
Choose the following choices that are true regarding Cap and Trade Policies.
There is some proof of success.
There are limits on emissions.
It doesn't have an expensive cost.
It is easy for emitters to cheat.
What are some ways to reduce global emissions?
Use wind turbines
Increase water vapor instead of carbon dioxide.
Use natural gas instead
Solar energy
Choose the three correct climate tipping points:
carbon dioxide levels reach 450 ppm
melting of Arctic sea ice
collapse of Amazon rainforest into Savannah biome
massive release of CO2 from thawing permafrost
