  2. Which statement is true about the relationship between Earth's average surface temperature and the amount of carbon dioxide in the atmosphere? - The 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? - The greenhouse effect would decrease but still occur naturally.
  4. Which statements are true about the effect of pollution on global warming? - - 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 - Workbook 17.1 - 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? - This 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? - Increased 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 - Carbon dioxide is found in ice cores analyzed by scientists. Which statement best explains a related concern about ice cap and glacial melting? - Carbon 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? - Ocean current energy has increased. Checkpoint 8 -

  1. Which are greenhouse gases that contribute to global climate change as they increase in the atmosphere? - .75 of 1
  • methane
  • nitrogen
  • carbon dioxide
  1. According to this graph, what change in the atmosphere over past decades is contributing to global climate change? - steady increase in atmospheric carbon dioxide
  2. What happens over time to the average global temperature as concentrations of carbon dioxide, methane, and nitrous oxide increase in the atmosphere? - The average global temperature increases.
  3. Which statement describes the relationship between air pollution and the greenhouse effect? - If air pollution increases, the greenhouse effect increases.
  1. Study the graph. - 1.6°C
  2. Using the data, what would the forecasted approximate average global temperature change be from the year 2000 to the year 2100 if global emissions become low? - Climate change will increase during this century regardless of low or high emission growth. Lesson 19 - Workbook 19.1 -
  3. Why do scientists rely on models to support the theory of human-caused global warming?
  • Models can make predictions by using data from the past and present
  1. Student A claims that all organisms will be able to adapt to global warming. Student B claims some organisms will be able to adapt to global warming. Which student claim is correct and why? - Student B is correct because some organisms will be able to reproduce, evolve, and adapt in time, but others may not.
  2. Why do people view global warming as caused by humans? - Carbon dioxide, a greenhouse gas, has increased in the atmosphere due to humans burning fossil fuels.
  3. Why are models better predictors now than in the past? - Technology has improved modeling. Checkpoint 9 -
  4. Which view of global warming looks at the present in the context of all of geologic history? - Global warming is due to natural causes.
  5. Which piece of evidence supports the view that global warming is a natural occurrence?
  • There have been periods of global warming in Earth's history.
  1. Why do people view global warming as a natural process? - There have been previous warming and cooling periods in Earth's history.
  2. The top model shows the ice over present-day Greenland, and the bottom model shows Greenland within the years to come. According to this model of Greenland's ice melt, what is expected to happen to the Greenland ice sheet? - It is expected to decrease in area.
  3. What have scientists learned from geoscience data and global climate models? - - The average surface temperature of the Earth is increasing.
  • Atmospheric carbon dioxide is increasing.
  1. What is the forecasted rate of global climate change and a future impact on Earth? - The rate of global climate change will probably increase and result in an increase in average global temperature. Lesson 20 - Unit Session 4 - Code: quiz 4
  2. Biodiversity is the sum of all the different species of animals, plants, fungi, and microbial organisms living on earth and the variety of habitats they live. - true
  3. Habitat destruction is a threat to biodiversity. - true
  4. Climate change does not effect biodiversity. - false
  5. Protecting our planet starts with us/you! - true Workbook 20.1 -
  • Chlorofluorocarbons increase global warming.
  1. Which conclusion can be drawn from these models of ocean acidification? - Oceans are becoming more acidic, and fewer corals can survive.
  2. Global warming is related to a change in the occurrence of droughts across the globe. The models below show areas affected by droughts over time. Which conclusion can be drawn from the models? - As global warming increases, the number of droughts increases.
  3. Which prediction can be made about the current rate of climate change and its impact on the number of forest fires that occur? - As the rate of climate change increases, the number of forest fires will also increase.
  4. Which prediction can be made about the current rate of climate change and its impact on coral reefs? - Coral reefs will decrease as temperatures increase from climate change.
  5. The burning of fossil fuels for energy, transportation, and other human needs is affecting Earth's systems. Which explanation best describes one of these effects? - Carbon dioxide is released when fossil fuels are burned, contributing to a rise in the average global temperature due to the greenhouse effect and decreasing the populations of some organisms.
  6. Which explanation best describes how deforestation modifies Earth's systems? - NOT - Deforestation removes trees that keep Earth cool. This causes the temperature of the Earth to increase and the polar ice caps to melt.
  7. The following map of South America shows the average (or mean) surface air temperature change due to deforestation in the region. The loss of trees allows more heat to be absorbed by the ground, leading to a drier climate for the region. Which claim is supported by this data? - One change to Earth's surface can create feedback that causes changes to other Earth systems.
  1. Given what is known about the impact of carbon dioxide in the atmosphere, which claims could you make from the data in this graph? - - Oceans become more acidic as carbon dioxide is dissolved in the water.
  • Ice sheets melt as the temperature of the Earth increases due to the impact of carbon dioxide on the greenhouse effect.
  • The increase in atmospheric carbon dioxide creates feedbacks.
  1. When fossil fuels burn, they react with oxygen to release carbon dioxide and water vapor. What effect do these substances have on global warming? - Carbon dioxide is a greenhouse gas that increases global warming
  2. What effect do greenhouse gases have on glacial and ice cap melting? - An increase in greenhouse gases increases the rate of melting.
  3. What is the impact of an increase in sea level due to increased melting? - Coastal areas are flooded.
  4. The images show the change in Arctic sea ice as the average global temperature increased from 1980 (top) to 2012 (bottom). Which statement best analyzes the impact of global warming during this time? - The oldest and thickest Arctic sea ice is melting as the temperature increases due to global warming.
  5. What is the effect of increased atmospheric temperature on the ocean's surface temperature and the occurrence of hurricanes? - The ocean's surface temperature is increasing, providing energy for hurricanes.
  6. What is the impact of increased atmospheric temperature on ocean currents? - Ocean currents move with greater energy.
  7. Which view of global warming supports making changes to the human way of life? - Global warming is due to human activity.
  8. What may contribute to the view that models are not predictors of global warming? - a misunderstanding of how models are constructed
