Worksheet time: 11mins
Which of the following is NOT a global consequence of global warming?
Rising sea levels
Increase in surface temperature
Melting of ice caps and sea ice
Decrease in insect born illnesses
Which of the following would be an example of a positive feedback mechanism associated with global warming?
Increase tree growth
Decreasing sea levels
Melting of ice caps
Increased acidity of water
Los Angeles has the largest smog problem in the US. Which factor does NOT contribute to smog formation there?
large amounts of vehicle exhaust
Large amounts of sunlight and heat
sea side breeze
Global climate change occurs because increasing concentrations of greenhouse gasses in
the troposphere absorbs outgoing IR radiation
the troposphere reflecting incoming IR radiation
the stratosphere absorbs outgoing IR radiation
neither the troposphere nor the stratosphere absorbs incoming UV radiation
An atmospheric or thermal inversion:
recycles the pollution in the air
traps the pollution under a layer of hot air
increases plant growth
depletes the ozone layer
Which of the following is most closely related to acid deposition?
Increasing aquatic biodiversity
An increase in buffering of lake water by sulfates
Leaching of metals from the soil
The death of species tolerant of low pH levels

Why are CFCs a more potent greenhouse gas than CO2?
they linger in the atmosphere for a short time
are much more efficient at absorbing thermal radiation
lack natural sources
are more difficult to remove from smokestacks and tailpipes
