Anthropogenic Climate Change
Questions & Answers
Lesson 16 - ANSWERS
Workbook 16.1 - ANSWERS
1. What effect does the increase in greenhouse gases have on the atmosphere that
contributes to global warming? - ANSWERSGreenhouse gases trap extra heat close to
the surface of Earth.
2. Which statement is true about the relationship between Earth's average surface
temperature and the amount of carbon dioxide in the atmosphere? - ANSWERSThe
average surface temperature is increasing as the amount of carbon dioxide in the
atmosphere increases.
3. If air pollution was reduced, what would happen to the greenhouse effect? -
ANSWERSThe greenhouse effect would decrease but still occur naturally.
4. Which statements are true about the effect of pollution on global warming? -
ANSWERS- Some pollutants, like chlorofluorocarbons, increase global warming by
trapping sunlight near Earth's surface.
- Some pollutants affect global warming by reflecting sunlight back into space or by
causing raindrops to form.
Lesson 17 - ANSWERS
Workbook 17.1 - ANSWERS
Since the Industrial Revolution, human activities have released additional carbon
dioxide into the atmosphere. What effect has additional atmospheric carbon dioxide had
upon ocean life? - ANSWERSThis carbon dioxide is absorbed by ocean water, causing
ocean acidification and loss of coral reefs.
The following map shows the global chlorophyll concentrations from 2002-2004. The
most concentrated areas of chlorophyll are near the continental coastlines, where water
is generally shallower. Which claim is supported by this data? - ANSWERSIncreased
carbon dioxide levels will result in more chlorophyll concentrated along the continental
coastlines because the amount of phytoplankton in oceans increases, disrupting
habitats and resources available to ocean life.
, Workbook 17.2 - ANSWERS
Carbon dioxide is found in ice cores analyzed by scientists. Which statement best
explains a related concern about ice cap and glacial melting? - ANSWERSCarbon
dioxide is released when the ice melts and the released carbon dioxide adds to global
warming.
Investigators used data from the Argo array to model ocean currents and speed. What
global trend have they discovered? - ANSWERSOcean current energy has increased.
Checkpoint 8 - ANSWERS
1. Which are greenhouse gases that contribute to global climate change as they
increase in the atmosphere? - ANSWERS.75 of 1
- methane
- nitrogen
- carbon dioxide
2. According to this graph, what change in the atmosphere over past decades is
contributing to global climate change? - ANSWERSsteady increase in atmospheric
carbon dioxide
3. What happens over time to the average global temperature as concentrations of
carbon dioxide, methane, and nitrous oxide increase in the atmosphere? -
ANSWERSThe average global temperature increases.
4. Which statement describes the relationship between air pollution and the greenhouse
effect? - ANSWERSIf air pollution increases, the greenhouse effect increases.
5. Which air pollutant helps decrease global warming? - ANSWERSsome aerosols
because they reflect sunlight back into space
6. How have Earth's systems been modified due to the burning of fossil fuels and
deforestation? - ANSWERSThe increase in atmospheric carbon dioxide has led to
global warming and changes in the biosphere.
7. In recent times, changes to the amount of _[blank]_ in Earth's atmosphere creates
feedbacks that cause changes to other Earth systems, such as the ocean. -
ANSWERScarbon dioxide
8. Which statements describe an effect of pollution on glacial and ice cap melting? -
ANSWERS- The Greenland ice sheet has been shrinking.
- There are fewer glaciers than there were 100 years ago.
9. When temperatures increase and the ice cap melts, what will happen to local coastal
areas? - ANSWERSCoastal areas will flood.
