Molten Young Earth
Open to everyone until Tuesday, September 29
To keep it, print it while it is open.
The young Earth was a hot, glowing ball of rock. Impacts and heat from inside kept its surface molten for a very long time.
In the picture
- Glowing molten rock in a surface crack: heat escaping from inside the young Earth.
- A rocky body hitting the surface: an impact that adds heat.
- A wide molten pool: surface rock kept liquid by heat.
Examples
- Rubbing your hands together makes them warm.
- A pot on a hot stove stays hot.
Key takeaways
- The young Earth was hit by many space rocks.
- Heat inside the Earth and heat from impacts kept its surface molten.
