Question 4
4.
Two new planets were recently discovered, R2D2 and C3PO. Each planet orbits a different star. The information below lists how these new planets are similar and how they are different.
Planets R2D2 and C3PO are similar in that:
Both are about the same size.
Both are about the same distance from their star (like Earth from the Sun).
Both stars that provide light energy (sunlight photons) are about the same surface temperature (similar to the sun).
Both stars that provide light energy (sunlight photons) are about the same brightness (similar to the sun).
Planets R2D2 and C3PO are different in that:
R2D2 has a thin atmosphere with little carbon dioxide or methane.
C3PO has a dense (thicker) atmosphere that is high in carbon dioxide and methane.
Using only the information provided above, choose a claim as to which planet is likely to be warmer on average.

Question 6
6.
Scientists are researching a new gas that is released into the atmosphere when manufacturing smartphones. The concentration of this gas in the atmosphere has recently been increasing rapidly, as shown in the graph below.
Scientists are concerned that this new gas might be contributing to increases in global temperatures.
Write two questions that would help identify or clarify the evidence for whether the gas could be causing changes in global temperatures? Number your questions when you type your response.

Question 7
7.
Analyze the graphs below, which show trends in per person fossil fuel use, population, and CO2 emissions in Country A and Country B over the same time period.
(Click on the graphs to view them in a larger window.)
The third graph shows that carbon dioxide (CO2) emissions increased in both countries from 1985–2005.
Based only on the data in the graphs, make a claim about what caused the increase in carbon dioxide emissions.
Claim: The increase in carbon dioxide emissions in the Total CO2 Emissions graph was caused by:
