how do the mass in density of the mantle compared with the mass and density of the Earth's core.

Answer 1

The mass and density of the Earth's core are higher compared to those of the mantle.

The Earth's core is divided into two parts: the inner core and the outer core. The inner core, which is a solid ball made primarily of iron and nickel, has a higher density and mass than both the mantle and the outer core. It is estimated to have a density of around 12-13 g/cm³.

The outer core, on the other hand, is a liquid layer also composed of iron and nickel. It has a lower density compared to the inner core but still higher than the mantle. The density of the outer core is roughly 10.7 g/cm³.

In contrast, the mantle is the largest layer of the Earth, located between the core and the crust. It is composed mainly of solid rock and has a relatively lower density compared to the core. The average density of the mantle ranges from 3.3 to 4.5 g/cm³, which is significantly lower than both the core's inner and outer parts.

Therefore, in terms of mass and density, the Earth's core has a higher value than the mantle.
