= = = = = ﻿ Layers of the Earth= = = =**__ Crust __**= The crust is 5-40 KM and it's the outermost layer. There is two laters, the oceanic crust an the continental crust. The crust is the most outer layer of the Earth.Its catergorized into two parts, the Oceanic crust and the continental crust. The oceanic ?crust is the smallest parth of earth and is 0-6 miles. The Continental crust is the second smallest area of the Earth composed primarly of crystalline rocks made low-density buoyant minerals dominated by quarts and feldspars.

Outer core: The outer core of 200-300 kilometers (125-188 miles) and represents about 4% of the mantle-crust mass. This layer is sometimes identified as part of the lower mantle due to its geographical nature.Inner core: The inner core is a solid section of the earth and is unattached to the mantle, being suspened by the molten outer core. Mantle The mantle is 2,885 KM. It's the layer above the core and 6 miles below the oceanic crust. The mantle is the thickest layer of the earth. It measures nearly 200 kilometers (1700 mi.). The mantle, made of hot rock is less dense than the metallic core. The very top of the mantle is cool and rigid. Just below that, the rock is hot and soft enough to move like a thick paste.

Outer core: The outer core of 200-300 kilometers (125-188 miles) and represents about 4% of the mantle-crust mass. This layer is sometimes identified as part of the lower mantle due to its geographical nature.Inner core: The inner core is a solid section of the earth and is unattached to the mantle, being suspened by the molten outer core. The Inner Core The inner core of the earth is the innermost hottest part. It is a primarily solid sphere about 1,220 km in radius. It's only 70% of the moon and is believed to consist of iron-nickel alloy.
