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.
