WebEarth's mantle is a layer of silicate rock between the crust and the outer core. It has a mass of 4.01 × 10 24 kg and thus makes up 67% of the mass of Earth. [1] It has a thickness of 2,900 kilometers (1,800 mi) [1] making up about 84% of Earth's volume. Web8 de mar. de 2024 · Earth’s core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly solid mantle. The core is found about 2,900 kilometers (1,802 miles) below Earth’s surface, and has a radius of about 3,485 kilometers (2,165 miles). Planet Earth is older than the core.
