Question

Quizplus · Accepted Answer

Venus has a thick atmosphere composed primarily of carbon dioxide, which creates a greenhouse effect that traps heat and causes the planet to have an average surface temperature of 864 degrees Fahrenheit (462 degrees Celsius). In contrast, Earth's atmosphere has much lower levels of carbon dioxide and a more diverse mix of gases, resulting in a much milder average surface temperature of 59 degrees Fahrenheit (15 degrees Celsius).
