Verified Answers
What do you think are the top contributors to the greenhouse effect you discovered in Our Blue Planet
that allows Earth to host liquid water? Select all that apply. - ✔✔Make a hypothesis
Nitrogen, oxygen, carbon dioxide
Comparing the two, which gases seem to follow the temperature trend? Select all that apply. -
✔✔Water
carbon dioxide
nitrous oxide
methane
Given the evidence you've investigated, could the atmosphere or parts of it be behind the observed
warming trend? - ✔✔Yes. Several atmospheric gases follow the observed warming trend,
including some known greenhouse gases.
Maximum Luminosity (W/sq. m) - ✔✔1364
Minimum Luminosity (W/sq. m) - ✔✔1359
What pattern do you see in the data? - ✔✔Solar luminosity is rising and falling in a cycle.
How many years does it take to get from peak luminosity to peak luminosity? - ✔✔11
, Average Global Temperature (degrees C) - ✔✔-18.2
Average Global Temperature (degrees C) - ✔✔-18.3
Average Global Temperature (degrees C) - ✔✔-18.4
Does this match well with the recent rate of change in Earth's temperature? Focus solely on the
difference in temperatures, since the simulation doesn't include atmospheric effects. Select all that
apply. - ✔✔Yes. The changes are appropriate in time and in range.
No. The luminosity changes go up and down, and the temperature trend is generally upward.
Which of the factors you investigated - albedo, distance from the Sun, solar luminosity, or the
atmosphere does the evidence indicate is most likely causing the recent rapid temperature rise
observed on Earth? - ✔✔Atmosphere
Which of these concentrations is the largest? - ✔✔1 ppm (part per million)
Shown in the table to the right are concentrations of the greenhouse gases you have identified
earlier. Order them in the list below from most to least concentrated in the atmosphere. For water,
use the highest concentration listed - ✔✔Water
Carbon Dioxide
Methane
Nitrous Oxide
