There are 3 parts of the earth, they are, crust, mantle and the core. Again, these parts have subparts within them. Among all the three parts of the earth, the mantle makes up the thickest layer of the earth. The outermost layer is the crust, the middle most is the mantle and the innermost layer of the earth is the core. Complete answer: Mainly the planet earth has 3 parts, they are, the crust, the mantle and the core. Again the core has 2 parts, they are, the solid inner core and the liquid outer core. The mantle and crust are mostly made up of rocky material, whereas, the inner and the outer core are made up of mostly iron and nickel. In the case of crust, the composition of the thin parts of the crust is silicate igneous rocks like basalt and the composition of the thicker crust is silicate rocks like granite. In the case of the mantle, the composition is silicate rocks that are rich in iron and magnesium. The outer core of the earth is a liquid layer, thick composed of iron and nickel which lies above the earth’s solid inner core and below its mantle. The inner core of the earth is primarily a solid ball consisting of iron and nickel alloy. ∴ In general, the central part of the earth is called its core. Note: The thin parts of the crust are also called the oceanic crust and the thicker crust is called the continental crust. The thicker crust will be less dense compared to that of the thin crust parts. The mantle has no subparts.
