1. THE EARTH’S LAYERS

2. THE EARTH IS DIVIDED INTO THREE LAYERS.

4. CRUST The crust is the layer that you live on so it is the most widely studied and understood.

5. CRUST The crust of the Earth is broken into many pieces called plates. Oceanic plates Continental plates The plates move along the magma found in the mantle. The plates move along smoothly but sometimes they get stuck and pressure builds up. https://www.youtube.com/watch?v=tWQwYQqd36A

7. MANTLE The mantle is the largest layer of the Earth. It is made of hot, dense rock. The rock in the mantle flows like asphalt because of the temperature differences found in the mantle.

8. MANTLE The movement of the mantle creates the movement of the Earth’s plates.

9. CORE The core of the Earth is much like a ball of very hot metals. The solid inner core is surrounded by a fluid iron outer core.
