Question

Based on our current understanding of how our solar system formed, it’s expected that Venus and Earth were created with a very similar overall composition. This means that they probably had the same amount of carbon dioxide and water vapor outgassed during their early history.

Earth’s atmosphere contains only a fraction of a percent (~.04%) of carbon dioxide, while Venus’s atmosphere is almost entirely carbon dioxide. What happened to all the carbon dioxide that must have been outgassed on Earth and where is it now?

During the collision that created Earth's Moon, most of Earth's atmosphere was blasted away. The carbon dioxide was then incorporated into the newly formed Moon.

Carbon dioxide on Earth was able to dissolve in the ocean water. Much of the carbon dioxide that gets dissolved in sea water is then used by marine organisms to make shells, which later become the rock limestone.

Plant life using photosynthesis has reprocessed the carbon dioxide on Earth. When plants die, the carbon dioxide is locked into rocks, becoming part of the surface of the Earth.

During the collision that created Earth's Moon, most of Earth's atmosphere was blasted away. The carbon dioxide was then incorporated into the newly formed Moon.
