The stifling of primary productivity
The production of an ENSO event
A La Nina Year
An El Nino year
2
Which of the following is an example of a positive feedback mechanism?
Melting of earth's ice leads to warmer temps & more melting
A spooked animal starting a stampede
Eating to make the hunger pains go away
Low O2 levels stimulating faster breathing, increasing O2
3
Which of the following is NOT considered an ecosystem service?
Water plants removing toxins from water
Bacteria decomposing waste
Clouds reflecting light from the sun to limit warming
Terrestrial plants and phytoplankton producing oxygen
4
Which of the following does NOT contribute to the urban heat island effect?
Cities have a lot of surface that converts light to infrared
Cities have less plant material, so less H2O to limit heat
Human beings generate a lot of heat & it gets trapped
Hardscape prevents H2O absorption, so no H2O to limit heat
5
Which of the following is NOT a gas that stores infrared radiation in the atmosphere?
CH4
O2
H2O
CO2
6
Which of the following is an accurate statement of poor human impact on the environment?
Invasive species are outcompeting native species
Levels of endangerment and extinction are rising
Some areas are so polluted that nothing can grow/live there
Amphibians, an indicator species, are in decline worldwide
7
The Federal Act that is responsible for regulating the trade of endangered species.
The Lacey Act
Convention on Intrntl Trade in Endangered Species (CITES)
The Marine Mammal Act
Endangered Species Act of 1973
8
At what point in history have mass extinctions been the result of anthropogenic activity?
End of the Pre-Cambrian Era
End of the Jurassic Period
End of the Cretaceous Period
Holocene Epoch
9
Where does the rain shadow effect form and what does it create?
Leeward... dry climate
Windward... wet climate
Windward... dry climate
Leeward... wet climate
10
What is THE major, immediate impact on humans as a result of loss of biodiversity?
Loss of aesthetic value
Loss of possible sources of food.
Loss of ecosystem services
Loss of species that may be used for medicine
11
Which of the following explains why trees can sequester atmospheric carbon?
Trees do not decompose so CO2 remains locked up
The water in trees prevents the loss of carbon
In photosynthesis, CO2 is converted to C compounds
Photosynthesis creates amino acids
12
Which of the following best explains why nations refused to ratify the Kyoto Protocol?
LDCs feel it's unfair for their opportunities to be limited
LDCs feel the cap is unfair since DCs caused the problem
If only DCs do it, the program is expensive and ineffective
DCs believe: unless LDCs cap it would just inhibit trade.
13
Which of the following is NOT an impact of an El Nino event?
Strengthening of the western prevailing winds
Floods in South America
Drop in primary productivity
Drought in Asia
14
Which of the following is an advantage of moving towards electric vehicles?
Point source C from a power plant is more easily sequestered
Electric vehicles produce battery acids/toxins
Electric vehicles have a longer range than gas powered ones
Coal is used to produce most electricity in the US
15
In which of the following ways does sea level rise?
Thermal expansion as hot water occupies more space than cold
Increased water from melting glaciers only
Sea level rise is not of concern.
Melting glaciers and thermal expansion
16
How much of the planet can be impacted by an ENSO event?
1/3
over 2/3
1/2
2/3
17
Which of the following is a reason for habitat loss?

Stop using machines as much
Make machines more efficient
19
Which of the following best explains/defines zones of upwelling?
Large populations of fish can be supported
Nutrient rich waters from below rise
Large populations of phytoplakton can be supported
Wind moves away from land masses creating a vacuum
