Extract
Venus, Earth, and Mars have carbon dioxide (CO2) in their atmospheres. CO2, absorbs infrared energy and traps heat in the planets' atmospheres. The higher the amount of CO2in an atmosphere, the more heat will be trapped. The density of the atmosphere is the mass of the air in every cubic meter at the surface. The table below gives the percents of CO2, in the planets' atmospheres, the amount of CO2in each atmosphere relative to Earth's, and the atmospheric densities of several planets. The table also includes data for the hypothetical Planet L and Planet V.
Based on the table, use the drop-down menus to make the following statement correct. _ experiences the least warming effect from CO2 because it has the _ of CO2 in its atmosphere.
Answer Choices
- A: smallest amount
- B: largest amount
- C: Mars
- D: Planet L
Correct Answer: A,C
Rationale: Mars has the least CO2 percentage in its atmosphere, leading to the least warming effect.
