How do the mass and the density of the mantle compare with the mass and density of Earth’s core? The mantle’s mass and its density are greater than that of the core.

Question

The mantle’s mass and its density are greater than that of the core.

The mantle’s mass is less than the core’s mass, but with greater density.
The mantle’s mass is less than the core’s mass, but with greater density.

The mantle’s mass and its density are less than that of the core.
The mantle’s mass and its density are less than that of the core.

The mantle’s mass is greater than the core’s mass, but with less density.

Answer 1

To compare the mass and density of Earth's mantle and core:

1. Mass: The Earth's mantle has a greater mass than the core. The mantle constitutes about 84% of Earth's total volume and a significant portion of its mass, while the core makes up around 15% of Earth's volume.

2. Density: The density of the Earth's mantle is less than that of the core. The mantle's density is about 3.3 to 4.5 grams per cubic centimeter, while the core, which is primarily composed of iron and nickel, has a density of about 10 to 12 grams per cubic centimeter.

Based on these comparisons, the correct statement is:

The mantle’s mass is greater than the core’s mass, but with less density.
