Differentiation of the Earth
... Differentiation is the process by which random chunks of primordial matter were transformed into a body whose interior is divided into concentric layers that differ from one another both physically and chemically. This occurred early in Earth’s history, when the planet got hot enough to melt. ...

The Layers of Earth
... Because the core is so hot, it radiates a natural heat to the upper layers. Because of this a current of heat comes into being. Those are also known as the convection currents. The convection currents cause the movement of the tectonic plates. This movement is called plate tectonics. The outer core ...
