Splet27. jun. 2024 · The Earth is made of three layers with different composition: the crust, mantle, and core. The lithosphere is made of the rigid, brittle, solid crust and uppermost mantle. Beneath the lithosphere, the asthenosphere is solid rock that can flow. The hot core warms the base of the mantle, which creates convection currents in the mantle. SpletIn terms of its constituent elements, the mantle is made up of 44.8% oxygen, 21.5% silicon, and 22.8% magnesium. There’s also iron, aluminum, calcium, sodium, and potassium. These elements are all bound together in the form of silicate rocks, all of which take the form of oxides. How do we know about the mantle and core?
