The diagram to the left shows what the inside of Pluto may look like. Pluto is mostly made of ice, with a small core of some rocky material buried inside.
If the interior is warm enough, the inside of Pluto may turn over like ice cream in a blender. This type of interior motion leaves clues on the surface of a planet. (Earthquakes are big clues about motions inside of the Earth).
These clues are important to search for now, while the surface of Pluto may still be exposed.
