How does the earth's mantle compare to other layers of the earth in terms of thickness and density?

Explained

Explanation:

Earth's mantle is 2868 Km thick and makes up about 80% of the total Earth's volume. The Density of mantle has a density of 4.5 gm/cm^3 and increases with depth as the pressure increases. Density of mantle is greter than that of crust but lower than that of core. Also, it has the heighest thickness among all three.
