Which of the following is the cause of the presumed pause in the rise of Earth's average global
surface temperature in the past few decades? correct answers Measurement bias from the greater
use of buoys
Judge the following: Volcanic eruptions are responsible for the recent observable climate
changes BECAUSE large and long lasting volcanic eruptions may have been influential in
contributing to Earth's climate shifts in the distant past. correct answers The assertion is
incorrect, but the reason is correct.
Judge the following: An increase in solar output explains all of the recent global warming
BECAUSE sunspot activity shows a strong correlation between solar activity and average Earth
temperate since 1880. correct answers The assertion is incorrect, but the reason is correct
What percentage of the Sun's energy that reaches Earth's surface is reflected back into space?
correct answers 6
Which of the following statements about Earth of 56 million years ago is correct? correct
answers It was marked by the extinction of many marine species.
Which of the following contributes the most to the greenhouse effect? correct answers Water
vapor
Which of the following ocean changes are predicted to result from increasing levels of carbon
dioxide in the atmosphere? correct answers 1. Development of a stronger thermocline
2. Migration of marine organisms into deeper waters and toward the poles
3. An increase in sea-surface temperature
Global engineering (geoengineering) proposals to reduce Earth's greenhouse effect include which
of the following? correct answers 1. Reflecting solar radiation back into space using man-made
devices
2.Spraying sulfate aerosols into the atmosphere to promote the formation of clouds
3.Adding nutrients to the ocean to accelerate the biological pump
Judge the following: The vast majority of carbon dioxide in the ocean-atmosphere system is
found in the ocean BECAUSE carbon dioxide is approximately 30 times more soluble in water
than are other common gases. correct answers The assertion and the reason are both correct, and
the reason is valid.
, Judge the following: The melting of Arctic sea ice by rising temperatures is an example of a
negative-feedback loop BECAUSE the lack of ice cover will result in the Arctic Ocean reflecting
more of the Sun's radiation. correct answers Both the assertion and the reason are incorrect
Judge the following: The melting of Arctic sea ice by rising temperatures is an example of a
positive-feedback loop BECAUSE particulate air pollution has a shading effect. correct answers
The assertion and the reason are both correct, but the reason is invalid
Judge the following: The net result of an increase in atmospheric moisture should be a decrease
in air temperature BECAUSE the heat absorption of water vapor in the atmosphere dominates
over the higher reflectivity of clouds. correct answers The assertion is correct, but the reason is
incorrect
Which of the following is considered paleoclimatological proxy data? correct answers Trapped
air bubbles in glacial ice
The most massive part of Earth's climate system belongs to the: correct answers hydrosphere
An increase in cloud cover due to higher moisture content in the atmosphere is an example of
a(n) ________. correct answers negative-feedback loop
Which of the following is not part of Earth's climate system? correct answers Exosphere
Combustion of fossil fuels results in a transfer of carbon from the: correct answers lithosphere to
the atmosphere
Judge the following: the movement of Earth's tectonic plates is responsible for the recent
observable climate changes BECAUSE during the geologic past, plate movements have
accounted for many dramatic climate changes. correct answers The assertion is incorrect, but the
reason is correct.
Judge the following: Volcanic eruptions are responsible for the recent observable climate
changes BECAUSE eruptions release into the atmosphere at least 130 times more heat-trapping
carbon dioxide than humans do. correct answers Both the assertion and the reason are incorrect
Judge the following: The dramatic and rapid climate change that is occurring on our planet
cannot be explained by variations in the obliquity of Earth's rotational axis BECAUSE this
variation has a cycle of about 41,000 years. correct answers The assertion and the reason are both
correct, and the reason is valid.
Judge the following: An increase in solar output explains all of the recent global warming
BECAUSE proxy data of solar brightness over the past 1000 years shows a correlation with
changes in climate. correct answers Both the assertion and the reason are incorrect
