Volcano Steam Makes Rain
Open to everyone until Wednesday, September 30
To keep it, print it while it is open.
Early Earth had many erupting volcanoes. Their steam rose, cooled, and fell as heavy rain that gathered in low basins to form the first oceans.
In the picture
- An erupting volcano: hot rock and gas burst from a vent.
- A rising steam plume: water vapour climbs into the sky.
- Heavy rain: cooled vapour falls as thick drops.
- A filling basin: water collects in a low rocky hollow.
Examples
- A kettle lets out steam that can cool into droplets on a cold window.
- A pot of water on a stove makes steam that condenses on a lid and drips back down.
Key takeaways
- Volcanoes released water vapour from inside early Earth.
- When the vapour cooled, it condensed into rain that helped fill the first oceans.
