The structure of the Earth
The structure of the Earth is made up of four layers, these layers are the following:
Atmosphere-a layer of Gases
Crust-A very thin layer of solid rock
Mantle- A thick layer of rock (some are partly molten)
Core- A central ball of very hot matieral
The outer part of the Earth, (the crust and some of the upper mantle) is called the lithosphere. This includes a series of separate pieces called techtonic plates.
Over millions of years ago, all these separate pieces were all fitted together, and this was called Pangae. However over a long period of time, the land masses began to move their separate ways causing them to move apart. Slowly, they formed the continents
