Overview
I'm working on a science question and need guidance to help me learn.
- Venus rotates backward and Uranus and Pluto spin about an axis tipped nearly on its side. Based on what you learned about the motion of small bodies in the solar system and the surfaces of the planets, what might be the cause of these strange rotations?
2. Why is there so much more carbon dioxide in the atmosphere of Venus than in that of Earth? Why so much more carbon dioxide than on Mars?
3. Is it likely that life ever existed on either Venus or Mars? Justify your answer in each case
4. Discuss the runaway refrigeratore effect and the role it may have played in the revolution of Mars
