Crust

• The Earth's Crust is like the skin of an apple.
  It is very thin in comparison to the other three
  layers.
  

10
Crust

• The crust of the Earth is broken into many pieces
  called plates. The plates move along the soft
  mantle which is the layer located located below
  the crust.

11
Crust

• The plates move along smoothly but sometimes they
  get stuck and pressure builds up.
  

12
Crust

• The pressure builds and causes an Earthquake as
  rocks break and crack.
  

13
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.

14
Mantle

• The movement of the mantle create the movement of
  the Earths plates.

15
Core

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