HEY FRND ☺✌✋Earth's interior is made up of a series of layers that sit below the surface crust. In order of depth, these layers include the solid, but flowing mantle, the liquid outer core and the solid iron outer core, which helps create Earth's protective magnetic field. The layers can also be categorized into the rigid outer lithosphere (which includes the crust and top portion of the mantle and makes up Earth's tectonic plates) and the athenosphere, the portion of the mantle that is solid, but made up of hot, weak, flowing rock. Read about the latest research on Earth's layers below.
The upper mantle
Is made up of rocks rich in magnesium and iron, and poor in silica; mostly peridotites.It is about 400 km thick and is much denser than the crust.It comprise 10% of the earth’s massThe Lower mantleIt is more dense and contains a greater amount of iron than the upper mantleIt is about 1900 km thickIt makes up 41% of the earth’s mass.

the structure of earth's interior is divided into three major concentric layers;
*crust it is the outermost layer of the earth.there are TWO TYPES OF CRUST CONTINENTAL CRUST AND OCEANIC CRUST.THE CRUST IS FURTHER DIVIDED INTO TWO PARTS SIAL AND SIMA . IT IS SEPARATED FROM THE MANTLE BY THE MOHOROVICIC DISCONTINUI
*MANTLE IT IS THE NEXT CONCENTRIC LAYER BELOW THE CRUST. THE THICKNESS OF MANTLE IS 2900 KM.THE AVERAGE DENSITY IS BETWEEN 3.5 AND 5.5 G/CM3.MANTLE IS DIVIDED INTO TWO PARTS THE UPPER MANTLE AND LOWER MANTLE.
*CORE IT IS THE INNERMOST LAYER OF THE EARTH.THE DIAMETER OF THE CORE IS ABOUT 7000KM . THE AVERAGE DENSITY OF CORE IS 11G/CM3.THE CORE HAS TWO SUB ZONES OUTER CORE AND INNER CORE.
