The Earth layers

The planet Earth is like a great globe formed by several materials with different density and different physical states, which are located forming concentric layers:

1- We live in the solid part, called the Lithosphere, or the earth’s crust.

2- This crust is covered in its three fourth parts by water: oceans and seas. This mass of water is the Hydrosphere.

3- Covering the Lithosphere and the Hydrosphere, there is a gaseous layer, called the Atmosphere which is made up of different layers:

-The Troposphere is the nearest the earth surface and where the weather happens.
-Above this layer is the Stratosphere where the Ozone layer is.
-Above the Stratosphere is the Ionosphere formed by ionized gases

4- The Endosphere is the layer below the lithosphere and goes down to the interior of the Earth.
