Exam 6: The Terrestrial Planets and Their Moons

One of the major differences between Earth and its neighboring planets Venus and Mars is the lack of large quantities of carbon dioxide in its atmosphere near the surface of the planet.If all these planets were originally formed with significant quantities of this gas in their atmospheres,where is a significant fraction of this carbon dioxide on Earth at the present time?
