The Earth is made up of four layers:
- Crust: Solid, outer layer of the Earth (5-40 km)
- Mantle: Molten rock beneath the crust (~2900 km)
- Outer Core: Molten iron layer beneath the mantle (~2250 km)
- Inner Core: Solid iron layer beneath the outer core (~1200 km)
- the density of the materials increases
- the pressure increases
- the temperature increases
The video below further divides the Earth's four layers (crust, mantle, outer core, inner core) according to their physical properties. If you have ever wondered if it is possible for someone to dig to the center of the Earth, you'll find the answer below, too!
Every year, Ms. Shon's students build scale models of Earth's interior. Keep in mind that In order to do this, students must understand both the interior structure of Earth, and how to convert units. Are you ready to design and build a scale model of Earth's interior? (interior = inside) I hope so!
