Layers of Earth

Open to everyone until Friday, October 2

To keep it, print it while it is open.

Earth is made of layers, like a ball with different parts inside. At the middle is a solid metal ball, then a hot liquid layer, a thick slow-moving layer, and a thin rocky shell where we live.

In the picture

  1. Inner core: a solid metal ball at the centre.
  2. Outer core: a hot liquid layer around the inner core.
  3. Mantle: a thick hot layer that moves very slowly.
  4. Crust: a thin rocky shell where we live.

Examples

  • A hard-boiled egg has a yolk, white, and shell like Earth’s layers.
  • A peach has a pit, flesh, and skin that show different inside parts.
