Question 1. Every day, tremendous amounts of the sun's energy strikes the earth. Why doesn't the earth overheat?

• Much of the heat melts rocks, forming lava deep inside the earth.
• Most of the energy is used in photosynthesis, to help plants grow and survive.
• The energy mostly is absorbed in various weather systems.
• The energy is ultimately radiated back to space.
• None of the above

Question 2. The jet streams in the United States generally flow from west to east because of

• ocean currents off the Pacific and Atlantic coastlines.
• convection currents between the troposphere and stratosphere.
• rotation of the earth.
• high pressure systems generated by the sun striking the North American continent.
• the moons gravitational pull.

Question 3. Which of the following activities have contributed the greatest amount of carbon dioxide into the atmosphere over the past 100 years?

• Increased farming and production of grains
• Increased reliance upon coal, oil, and natural gas
• Deforestation of rain forests and other parts of the world
• Volcanic eruptions
• Widespread forest fires

Question 4. Which of the following illustrates a risk assessment of climate system change?

• Using natural gas instead of coal to generate electricity
• Using solar and nuclear power to generate electricity instead of burning coal
• Measuring the levels of carbon dioxide in the atmosphere
• Determining what sorts of crops will be better suited to the new climate
• Determining the best location for a new coal power plant

Question 5. When an automobile heats up in bright sunlight with windows rolled up, the glass in the car functions most like

• rain in the atmosphere
• clouds in the atmosphere
• sulfate aerosol in the atmosphere
• carbon dioxide in the atmosphere
• soil in the lithosphere

Question 6. Rising GHGs in the 21st century most confidently predict

• increases in global temperatures and sea levels
• decreases in polar temperatures but increases in sea levels
• decreases in sea levels but increases in polar temperatures
• increases in ocean pH and increases in sea levels
• None of the above

Question 7. Rising GHGs in the 21st century most confidently predict

• increases in global temperatures and sea levels
• decreases in polar temperatures but increases in sea levels
• decreases in sea levels but increases in polar temperatures
• increases in ocean pH and increases in sea levels
• None of the above

Question 8. Which of the following U.S. national parks would be mostly eliminated by a 1 m rise in sea level?

• Glacier National Park
• Yellowstone National Park
• Everglades National Park
• Yosemite National Park
• None of the above

Question 9. Climatologists warn of a tipping point when global temperatures trigger catastrophic events and sea levels rise of close to 2 meters. About how much warmer does the world need to get for this tipping point to happen?

• Increased precipitation over the continents
• Melting of the Greenland Ice Sheet
• Thermal expansion of the oceans
• Melting of the polar ice cap
• Increased precipitation over the oceans

Question 10. The most effective way to reduce GHG emissions is to increase

• the production of electric cars
• energy efficiency and renewable energy
• our reliance on widely available natural gas resources.
• the use of coal gasification plants and scrubber technologies to reduce sulfur emissions
• expanded oil drilling in ANWR
