Bot how do the mass and the density of the mantle compare with the mass and density of Earth's core? pick one of these answers. 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 greater than the core's mass, but with less density. 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.

The correct answer is: the mantle's mass is greater than the core's mass, but with less density.
To compare the mass and density of Earth's mantle and core, we need to understand the composition and properties of each layer.
Earth's core is divided into two parts: the outer core and the inner core. The outer core is composed mainly of molten iron and nickel, while the inner core is solid iron-nickel alloy. The core is the densest layer of the Earth.
The mantle, on the other hand, is made up of solid rock, primarily silicate minerals like olivine and pyroxene. It surrounds the core and comprises most of Earth's volume.
With this information, we can now analyze the given answer choices:
1. The mantle's mass and its density are greater than that of the core: This is not accurate. The core is denser than the mantle.
2. The mantle's mass is less than the core's mass, but with greater density: This is not accurate either. The core has both greater mass and density compared to the mantle.
3. The mantle's mass is greater than the core's mass, but with less density: This is also incorrect. The core has greater mass and density.
4. The mantle's mass and its density are less than that of the core: This is the correct answer. The core has a higher mass and density compared to the mantle.
So, the correct answer is that the mantle's mass and density are less than that of the core.
