3. Plates Of The Earth Home
The surface of the Earth is broken up into large plates. It’s easy to confuse these plates with the Earth’s crust – the thin outermost layer of the Earth. But there is more to the structure of the Earth than this simple image of a ‘cracked egg-shell’.
The Earth’s layers can be defined in two different ways – based on the chemical composition or the mechanical properties of the rock. To understand what plates are, it is important to understand both of these different models.
