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

The mantle’s mass and its density are greater than that of the core.
The mantle’s mass and its density are greater than that of the core.
The mantle’s mass is greater than the core’s mass, but with less density.
The correct statement is: The mantle’s mass and its density are less than that of the core.
The correct statement is:
The mantle is both solid and liquid, while the inner core is entirely solid.
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.
To arrive at this answer, we need to understand the composition and properties of these layers. The Earth can be divided into several layers, including the crust, mantle, and core.
The mantle is located between the crust and the core. It is mostly composed of solid rock, but due to the high temperature and pressure, some parts of the mantle can become partially molten or behave like a viscous liquid over long periods of time. This unique behavior is known as "plasticity."
On the other hand, the inner core is the deepest layer of the Earth's core. It is made up of solid iron and nickel. The intense pressure at the core's center keeps the iron and nickel in a solid state, despite the extremely high temperatures.
Based on this knowledge, we can conclude that the mantle is both solid and liquid, while the inner core is entirely solid. Therefore, the correct statement is "The mantle is both solid and liquid, while the inner core is entirely solid."
