Which of the following best explains why Mars' and Venus' surface temperatures vary, despite both planets having atmospheres that contain mostly carbon dioxide? (1 point)

Answer 1

Mars and Venus have different surface temperatures due to variations in their atmospheres and their distance from the Sun. While both planets have atmospheres that contain carbon dioxide, Venus has a much denser atmosphere than Mars. The thick atmosphere of Venus traps heat from the Sun, leading to a runaway greenhouse effect and extremely high temperatures on its surface. In contrast, Mars has a much thinner atmosphere, which cannot effectively trap heat, resulting in much colder temperatures.
