TEST #2 DISC OF NATURAL SCIENCE
EXAM QUESTIONS WITH CORRECT
ANSWERS
In the weather vs. climate discussion we examined in class climate was represented by:
- ANSWER-both anthropogenically influenced events and naturally occurring events
over a longer time frame
The predicted sea level rise for Long Branch under the extreme scenario of no
curtailment in carbon emissions is 11.6 feet. Parts of which street would be then under
water? (For this you need to use the Surging Seas online tool.) - ANSWER-Joline
Avenue
Which is not a greenhouse gas? - ANSWER-Oxygen
Which of these lifestyle changes would have the greatest impact on the amount of
carbon emissions you produce? - ANSWER-Eating a plant-based diet.
What is the Keeling curve? - ANSWER-A plot of the atmospheric carbon dioxide
concentration over time.
What is responsible for the fact that the earth does not experience the temperature
extremes seen on the moon? (Review the video linked in slide 15 of the Climate
Science slides.) - ANSWER-The sun-warmed earth returns infrared radiation to the
atmosphere, and it is trapped there.
The albedo effect would be most pronounced where? - ANSWER-clouds
glaciers
Which is not a source of information scientists can use to estimate atmospheric carbon
dioxide concentration or global average temperature? - ANSWER-Volcanic emissions
What does the NOAA global temperature anomaly plot tell us? - ANSWER-That after
about 1978 the annual global temperature consistently exceeded the 1880-2015
average global temperature.
As a result of climate change, species and ecosystems are experiencing changes in all
of the following except: - ANSWER-Habitat and ranges
Predator-prey interactions
Disturbances by climate caused drought, fire, or floods
Abundance
All are involved
, Which of the following factors can lead to Global Warming? - ANSWER-burning of fossil
fuels
Milankovich Cycle components
deforestation
Solar radiation

molecules, share electrons
Carbon - ANSWER-Forms the backbone of all of life's essential molecules
intermolecular forces - ANSWER-forces between molecules
Neutral molecules - ANSWER-One part of the molecule has more positive or negative
charge than another
