The Earth can be divided into several distinct layers based on its internal structure. These layers are the lithosphere, mantle, and core. Each of these layers is characterized by different thickness, diameter, density, and volume and density of minerals.
The lithosphere is the outermost layer of Earth, and it is composed of the crust and the uppermost part of the mantle. The thickness of the lithosphere varies from about 40 to 280 km, and its density ranges from 2.7 to 3.3 g/cm³. The volume of the lithosphere is estimated to be about 100 billion cubic kilometers. The minerals that constitute the lithosphere include silicates, oxides, and carbonates.
The mantle is the layer below the lithosphere, and it is much thicker than the lithosphere, averaging about 2,900 km in thickness. The mantle is predominantly composed of silicate minerals, and its density is estimated to be about 4.5 g/cm³. The volume of the mantle is estimated to be about 4.5 trillion cubic kilometers. The mantle is also divided into several distinct zones, including the upper, middle, and lower mantle.
The core is the innermost layer of the Earth and is made up of two parts: the outer core and the inner core. The outer core is a liquid layer with a thickness of about 2,300 km, while the inner core is a solid layer with a diameter of about 1,220 km. The density of the core is estimated to be about 10 g/cm³, making it the densest layer of the Earth. The volume of the core is estimated to be about one-third of the Earth's total volume.
The dividing zones between these layers are known as the Moho discontinuity, which separates the crust from the mantle, and the Gutenberg discontinuity, which separates the mantle from the core. These boundaries are marked by significant changes in the physical properties of the Earth's materials, including seismic velocities, heat flow, and electrical conductivity.
