The Cooling of Venus
The following may be the history of Venus.
- at the conclusion of forming it continued to be hit with leftover material.
- Venus warmed from inside, and separated into layers. Because Venus is close to the sun, the atmosphere formed differently than did the Earth's, as sugggested by the Goldilocks idea.
- After that, Venus started cooling down. The crust began to thicken, just like jello hardens when it is being made. The hardening crust prevented continental drift. This also prevented the recycling of the atmosphere.
- Despite the thick crust, volcanic activity may continue to this day as Venus continues to cool.
