What layer comes below the crust?
Question
What layer comes below the crust?
Solution
The layer that comes below the crust is the mantle. The mantle is the second layer of the Earth and is located directly beneath the crust. It is the thickest layer and makes up about 84% of Earth's volume. It is primarily composed of silicate rocks rich in magnesium and iron. The mantle is divided into two sections: the upper mantle and the lower mantle. The upper mantle and the crust together form the lithosphere, which is the rigid outer layer of the Earth.
