d. The mantle is both solid and liquid, while the inner core in entirely liquid

Answer 1

Answer:

a. the mantle is solid and liquid and the inner core is solid

Explanation:

Answer 2

Regarding the Earth's layers, it can be said that the mantle is solid and liquid, while the Earth's inner core is totally solid. The mantle is the largest layer on Earth, with 83% of the planet's volume, and the core corresponds to a third of the Earth's mass.

The Earth's mantle is located above the inner core and below the crust, therefore it constitutes the middle layer of our planet.

It is composed of iron and silicon silicates, whose rocks are in a pasty state and increasingly liquid in relation to the depth and temperature increase coming from the Earth's core.

It is through the Earth's mantle that volcanic eruptions and the movement of tectonic plates occur.

The Earth's core, on the other hand, is divided into an inner and an outer core, the inner core being totally solid, with high temperatures reaching up to 5,000°C.

It is formed from a metal alloy of solid iron and nickel due to high pressure.
