Even though Venus is farther from the Sun than Mercury, its surface temperature is significantly higher than Mercury's. What is the primary reason for this?
  1. Venus has active internal nuclear reactions.
  2. Venus reflects almost all sunlight back into space.
  3. Venus has a thick atmosphere rich in carbon dioxide creating a strong greenhouse effect.
  4. Venus rotates much faster on its axis than Mercury.

Solution

Venus is covered by a dense atmosphere composed mostly of carbon dioxide, which traps solar heat through an extreme greenhouse effect.
