The Mantle Story
The Mystifying Structures Hidden Within Earth’s Mantle
The mantle is a layer inside a terrestrial planet and some other rocky planetary bodies. For a mantle to form, the planetary body must be large enough to have undergone the process of planetary differentiation by density. The mantle is bounded on the bottom by the planetary core and on top by the crust. The terrestrial planets, the Moon, two of Jupiter's moons and the asteroid Vesta each has a mantle made of silicate rock. Interpretation of spacecraft data suggests that at least two other moons of Jupiter, as well as Titan and Triton, each have a mantle made of ice or other solid volatile substances.
