Explanation:
The Structure Of The Earth
Earth Cross section
Our planet was most probably created about five billion years ago. At first it was just a ball of molten rock and gasses with little order to its structure. The immense amount of heat energy released at this time is still being radiated, even today, as the planet slowly cools down.
As the cooling began, more dense materials such as iron (Fe) sank into the core of the Earth, while lighter silicates (Si), other oxygen (O) compounds, and water rose towards the surface. In consequence distinct layers began to form.
The Earth is made up of several of these different layers. The outer layer is called the Crust and is made of the lighter, less dense, rocks that floated to the surface when the Earth was formed.
The layer of rock below the crust is called the Mantle This is about 2,900km thick and contains most of the mass of the Earth.
Below the mantle is the Core. This is probably liquid with a solid centre made of iron with a few other metals such as nickel.
