What planet has a surface temperature of over 400 degrees celsius, no oxygen, an atomsphere comprised mainly of carbon dioxide and tremendous atmospheric pressure?

  • Correct Answer: venus
  • Mars
  • uranus
  • Earth

Explanation: The atmosphere of Venus is markedly different from that of Earth. The gases in the Venusian atmosphere are 96.5% carbon dioxide and 3% nitrogen. The atmospheric pressure on Venus is roughly 92 times that of Earth, so the amount of nitrogen on Venus would contribute a pressure well over 2700 mm Hg. And there is no oxygen present, so we couldn’t breathe there. Not that we would want to go to Venus – the surface temperature is usually over 460°C.
