  21. Earth's internals structure
    Crust: hard and rigid, it's earth's outermost and thinnest layer, only 5 km thick under the oceans and averaging 30 km thick under the continents

    Mantle: Subdivided into two regions, upper and lower, this dense layer made of hot, semi-solid rock is located directly below the crust and is about 2900 km thick

    Outer Core: The outer core is the only liquid layer of the earth - a sea of mostly iron and nickel. it is roughly 2890 to 5150 km below the surface and is about 2300 km thick

    Inner Core: An extremely hot, solid sphere of mostly iron and nickel at the centre of the earth. it is 5150 to 6378 km below the surface and about 1200 km in diameter.
  22. Crust and Mantle structure
    lithosphere:  made up of the crust and a tiny bit of the upper mantle, this layer is divided into several constantly (very slow) moving plates
