GHY 1012 Final Test
With Solution
Which of the following has the highest albedo - ANSWER snow
Which region of the globe is experiencing more rapid warming than the rest?
- ANSWER artic
In just the past decade, CO2 in our atmosphere began to exceed what
benchmark concentration.......indicating to scientists that CO2 levels were
exceeding the range of natural variability? - ANSWER 300 ppm
During the autumnal equinox, how many hours of sunlight did we receive
here in Boone, NC? - ANSWER 12
Atmospheric pressure __________ with distance from the earth's surface. -
ANSWER decreases
Which of the following is an example of a climate feedback? - ANSWER (all of
the above)
-Increases in NPP result in increased atmospheric CO2 assimilation which
results in less greenhouse forcing
, -Enhanced melting of the cryosphere results in more exposed land surface
which results in the release of methane which results in enhanced
greenhouse forcing
-Enhanced melting of the cryosphere results in less reflective capacity of the
earth which results in enhanced energy absorption
Which of the following is the most objective source of climate change
information? - ANSWER The Intergovernmental Panel on Climate Change
(IPCC)
The discovery of ___________ was key to establishing the theory of continental
drift. - ANSWER Sea-floor spreading
What makes up about 80% of the Earth's total volume, as is relates to the
Earth's structure? - ANSWER Mantle
When El Niño occurs every three to seven years, a mass of warm Pacific water
that is usually pushed westward by trade winds - ANSWER Becomes much
warmer than usual, strengthening trade winds, Cools dramatically
Which of the following is NOT a characteristic of glacial periods. - ANSWER
High sea levels
