The earth is made up of three layers, the crust, the mantle and the core. Each layer has different characteristics and temperatures, becoming warmer as it approaches the core.
The Earth is formed by three layers that are not uniform in thickness, composition, or characteristic. These layers are:
Earth's crust: Most superficial layer, relatively thin structure and very rocky.
Mantle: Located below the crust, it has solid properties.
Core: Earth's warmest inner layer. It has two parts:
Outer core: formed by nickel and liquid iron.
Inner core: Also formed of nickel, but with solid iron.
