In the picture
- Volcano plume: hot gases and water vapor rising from the young planet
- Steam cloud: water vapor cooling above the volcano
- Dark rain: water falling into the growing ocean
- Icy comet: frozen water and gases arriving from space
Examples
- Steam rising from a boiling kettle
- Frost on a freezer wall melting into drops
Key takeaways
- Volcanic gases and icy impacts both added water and gases to the early planet.
- When the planet cooled, that water vapor condensed into the first oceans, and the gases formed the early atmosphere.
