B. Valley formations
C. Earthquakes
D. Thunderstorms
D. Thunderstorms.
C. The mantles mass is less than the cores mass, but with greater density.
To compare the mass and density of the mantle with that of the Earth's core, we need to understand that the Earth's core is divided into the outer core and the inner core. The inner core is a solid sphere at the center, while the outer core is a liquid layer surrounding it. Here's how we can determine the correct option:
1. Mass comparison: The mantle is the layer located between the crust and the core. It is much thicker than the core. The core, including both the outer and inner core, has a smaller volume compared to the mantle. Since density is mass divided by volume, if the core has less mass, it is not possible for it to have a greater density.
2. Density comparison: The core is primarily composed of iron and nickel, which are denser materials compared to the mantle. Therefore, the density of the core is greater than that of the mantle.
Considering these factors, the correct option would be:
C. The mantles mass is less than the cores mass, but with greater density.
