What are the layers of the Earth?

• The Earth is made of four layers, the inner core,
  
• the outer core, the mantle, and the crust. The
  crust
• is the outermost layer, followed by the mantle,
  outer core,
• and the inner core. The lithosphere is a another
  layer of
• the Earth that is made up of the crust and the
  upper part of
• the mantle.

The Earths Layers

• Crust - The Earth's outermost surface is called
  the crust. The crust is relatively light and
  brittle. Most earthquakes occur within the crust.
  
• Mantle - The mantle is relatively flexible so it
  flows instead of fracturing.
• Outer core Fluid layer that contains iron. When
  it flows it generates the Earths magnetic field.
  
• Inner core Solid innermost layer of the Earth.
