ELI5: Explain Like I'm 5

Chaos terrain

Chaos terrain is like a big messy pile of rocks and cliffs that can be found on some planets and moons in our solar system. Think of it like a giant pile of Legos that has been knocked over and jumbled up.

Scientists believe that chaos terrain is formed by the movement of ice and rock below the surface of these celestial bodies. Over time, the pressure and heat cause the ice to melt and reform, creating these jagged and chaotic landscapes.

Additionally, sometimes the ground above the melted ice collapses, creating deep valleys and sharp cliffs. This can create a very rough and dangerous terrain for any spacecraft or rover that might try to explore these areas.

So basically, chaos terrain is a big messy pile of rocks and cliffs caused by the movement of ice and rocks below the surface of some planets and moons. It's like a giant pile of Legos knocked over and jumbled up.
