Five friends were talking about Earth's interior. They each had different ideas about what the inside of Earth was like. This is what they said:

Rudy: I think we would see layers. Most of the inside of Earth will be hot liquid.

Lizette: I think we would see layers. Most of the inside of Earth will be solid.

Zara: I think we would see three layers with a giant magnet in the center of Earth.

Mateo: I don't think there are layers. Earth is made up of rocks and dirt with hot liquid found in cracks.

Haliaka: I think we would see sections of solid and liquid Earth with gaps in between.

Who do you think has the best idea? Explain your thinking.
