Here are the responses to your questions:
Question 1
Which is evidence of climate-forced sea level rise?
- Response: Submerging of low islands and coastlines
Question 2
Which are true about changes in carbon dioxide in the Earth's atmosphere since 1860? Select the two correct answers.
- Response:
- The increases in carbon dioxide are caused by human activity.
- The rate of change in carbon dioxide is exponential.
Question 3
Next to each item in the left column, click the circle under the correct topic that scientists would use the item to study.
- Ocean temperature: Climate change
- Carbon dioxide levels: Atmospheric studies
- Kinds of plants: Ecology/Biology
- Rainfall: Hydrology/Meteorology
- Chemical isotopes in foraminifera: Paleoclimatology
- Ice: Glaciology
- Tree rings: Dendrochronology
- Fossilized pollen grains: Palynology
Question 4
What is a quality of a greenhouse gas?
- Response: Absorbs and re-emits infrared radiation
Question 5
Which items directly contribute to sea level rise?
- Response: Expansion and melting of land ice
Question 6
Which choice gives the correct sequence of a chain of events that show cause-and-effect relationships resulting from human activity?
- Response: Increased carbon dioxide in the atmosphere; increased water vapor in the atmosphere; increase in severe storms; increased flooding
Question 7
Governments want to decrease the negative effects of climate change. Which of these measures would be most effective? Select the two correct answers.
- Response:
- Give tax incentives for energy conservation in homes and businesses.
- Transition from power plants that burn natural gas to those that do not use fossil fuels.
Question 8
Next to each blank, click the downward arrow and select the correct answer.
- When it is burned to produce electricity, coal emits the most carbon dioxide. This fossil fuel accounted for 24% of the electricity generated in the United States and emitted 68 percent of the carbon dioxide produced by generating electricity.
Question 9
Scientists are monitoring the pH of oceans. Which of these are they most likely studying?
- Response: The health of coral reefs
Question 10
How would a weaker jet stream help to cause extreme flooding?
- Response: It would allow storm systems to stall in an area.
Question 11
How would Earth be different without the greenhouse effect?
- Response: There would be more ice on Earth's surface.
Question 12
Which is the link between fossil fuel use and flowers blooming earlier in the spring season?
- Response: A warmer Earth due to fossil fuel emissions has milder winters and earlier springs.
Question 13
Scientists say the planet Venus has a "runaway greenhouse effect." What condition would you expect on Venus as the result of a runaway greenhouse effect?
- Response: The planet is extremely hot.
Question 14
Which gas has recently increased in the mesosphere, creating a rise in water vapor which has led to the formation of high-altitude clouds that are visible at night?
- Response: Ozone
Question 15
Drag and drop the correct answer that goes in each blank.
- Good ozone is important in nature because it protects living organisms from UV radiation. Scientists know that good ozone is mostly located in the stratosphere. Scientists know that bad ozone can be located in the troposphere. Recent research has shown that bad ozone is harmful to human health and vegetation.
Question 16
Next to each blank, click the downward arrow and select the correct answer.
- Climate change is increasing. This results in sea level rise, which causes coastal erosion. Severe storms fueled by climate change cause all of the following EXCEPT a decrease in rainfall. Ocean acidity caused by climate change causes all of the following EXCEPT an increase in fish populations.
Question 17
Next to each blank, click the downward arrow and select the correct answer.
- Machines began replacing animals and humans for doing hard labor since the industrial revolution. This transformation has affected the economy. As a result, increased greenhouse gas emissions since 1960. Some scientists believe that all of the following have occurred as a result EXCEPT a decrease in global population.
