The outermost layer of the Earth is a rocky crust. Beneath it is a plastic, highly viscous upper mantle, followed by a more dense and rigid lower mantle. In the center is a liquid outer core and a solid inner core.
The interior structure of the Earth is layered in spherical shells, like an onion.
These layers can be defined by their chemical and their rheological properties.
The Earth is composed of four different layers. Many geologists believe that as
the Earth cooled the heavier, denser materials sank to the center and the lighter ...
