The earth has core is the innermost layer and is made up of iron, nickel, and alloy rich content and is about 2,900 to 5100 km in depth, has a surface temperature that goes up to 5700 K and is responsible for producing the magnetic waves and the semis waves.
And there is the densest part of the planet, followed by the cover of the mantle that is made of silicate rocks and ice and planetary layer that undergoes differential density and has a thickness of 2,900 km and is divided into the three layers of the upper, middle and the lower.
The uppermost layer is called the asthenosphere and forms the base of the oceanic crust followed by the lithosphere crust. That is igneous, metamorphic and the sedimentary ricks and has a density of 2.83 g/cm.
