Question

Quizplus · Accepted Answer

Venus has the greatest difference in temperature between its "no atmosphere" temperature and its actual temperature. Its "no atmosphere" temperature is approximately -234 °C while its actual temperature is about 462 °C, resulting in a difference of almost 700 °C due to its thick and dense atmosphere of carbon dioxide and sulfuric acid clouds. Mercury has a small difference in temperature due to its proximity to the Sun, Earth has a moderate difference due to its moderate atmosphere and distance from the Sun, the Moon has no atmosphere so its "no atmosphere" temperature is close to its actual temperature, and Mars has a moderate difference due to its thin atmosphere and distance from the Sun.
