Based on evidence the Earth provides, scientists
have produced a model of the Earths interior.
The Earth has 4 layers inner core, outer core,
mantle and crust. Roll your mouse over the Earth
model on the left to learn about the different
layers of the Earth.
3
Inner Core Solid Temperature of about
5000C Experiences the greatest amount of
pressure.
4

• Outer Core
• Composed of mostly molten metal
• Scientists believe that the other core is liquid
  

5

• Mantle
• Lies above the outer core
• Largest layer of the Earths interior
• Solid consistency believed to be like putty

6

• Crust
• Outermost layer
• Crust is very thin when compared to the other
  layers
• Thinnest under the oceans and thickest through
  the continents
