How do the mass and the density of the mantle compare with the mass and density of Earth’s core?(1 point)
Responses
The mantle’s mass is greater than the core’s mass, but with less density.

The correct statement is: The mantle’s mass is greater than the core’s mass, but with less density.
The correct statement about the inner core and mantle of the Earth is:
The mantle is both solid and liquid, while the inner core is entirely solid.
The correct statement is: The mantle is both solid and liquid, while the inner core is entirely solid.
To determine the correct statement, we need to understand the structure of the Earth's interior. The Earth is composed of several layers, including the crust, mantle, outer core, and inner core.
The mantle is located between the crust and the outer core. It is primarily made up of solid rocks, but due to high temperatures and pressure, some of the rocks in the mantle can partially melt and flow in a process called convection. This means that the mantle can exist in both solid and liquid states, depending on the specific conditions.
On the other hand, the inner core is located at the very center of the Earth, beneath the outer core. It is primarily made up of solid iron and nickel due to extremely high pressure, despite the intense heat. Therefore, the inner core is entirely solid.
So, the correct statement is that the mantle is both solid and liquid, while the inner core is entirely solid.
