- The inner core is in the centre and is the hottest part of Earth. With its immense heat energy, the inner core is like the engine room of the earth.
- The outer core is the layer surrounding the inner core. It is still extremely hot, with temperatures similar to the inner core.
- The mantle is the widest section of the earth. in the upper parts of the mantle the rock is hard, but lower down the rock is soft and beginning to melt.
- The crust is the outer layer of the earth. The crust is he solid rock layer upon which we live
