Earth Layers

The Earth has its inner structure divided into three layers:
 
- Lithosphere or crust Land: external and solid layer surrounding the Earth. It consists of rocks and soil of varying levels and consists of large amount of minerals.
The lithosphere has thickness of about 72 km below the continents, which is called continental crust, and thickness of approximately 8 km below the oceans, which is called oceanic crust.
The rocks that make up the lithosphere can be:
- * magmatic rocks or igneous rocks: are formed by magma located below the rocks which solidify.
- * Sedimentary rocks: Formed by the lack of debris caused by erosive action.
- * metamorphic rocks: Formed by magmatic and sedimentary rocks that have changed.
- Robe: layer located just below the crust Earth and extends to almost half of the Earth's radius is formed by various types of rocks that due to high temperatures, are in paste form and receive the magma name.
 
- Core: is the innermost layer of the planet and is abo
