Earth’s Cracked Shell
Open to everyone until Tuesday, September 29
To keep it, print it while it is open.
Earth’s outer shell is not one solid piece. It is cracked into large rigid pieces that slowly shift against each other.
In the picture
- A large rigid piece of Earth’s outer shell
- Two neighboring pieces sliding sideways past each other
- Two pieces pulling apart with a widening gap
- Two pieces pressing together at their edges
Examples
- Cracked pieces of an eggshell on a soft-boiled egg
- Ice floes on a pond nudging and sliding past one another
Key takeaways
- Earth’s outer shell is made of large rigid pieces.
- These pieces move very slowly and can slide, pull apart, or push together.
