How do the mass and the density of the mantle compare with the mass and definitely at earths core
The mantle is a layer of the Earth located between the crust and the core. It is made up of solid rock, composed mainly of silicate minerals. The mass of the mantle is estimated to be around 67% of Earth's total mass.
In terms of density, the mantle has an average density of about 3.3 grams per cubic centimeter (g/cm³). However, the density of the mantle can vary depending on depth and composition, with values ranging between 2.6 g/cm³ near the crust-mantle boundary and up to 5.7 g/cm³ near the mantle-core boundary.
On the other hand, the Earth's core can be divided into two layers: the outer core and the inner core. The outer core is a liquid layer primarily composed of iron and nickel, while the inner core is a solid, dense sphere mostly made up of iron. The core's mass is estimated to be approximately 33% of the Earth's total mass.
The outer core has an average density of about 10-12 g/cm³, while the inner core has a higher density of around 12-13 g/cm³.
Therefore, while the core's mass is relatively smaller (33% of Earth's total mass) compared to the mantle (67% of Earth's total mass), both the core and the mantle have significantly higher densities compared to the crust.
The mass of the mantle and the Earth's core are significantly different. The mantle constitutes about 84% of the Earth's total mass, making it the largest layer by mass. In contrast, the core accounts for only about 15% of the Earth's mass.
As for density, the core and mantle also differ in this aspect. The core is significantly denser than the mantle. The average density of the mantle is around 3.3 grams per cubic centimeter (g/cm³), while the outer core has a density of approximately 9.9 g/cm³, and the inner core has an even higher density, estimated to be around 13 g/cm³. So, the core is much denser compared to the mantle.
