Earth'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 (8.84 × 10 24 lb) and makes up 86% of the mass of Earth. [1]

Apr 30, 2024 · The mantle is the mostly solid bulk of Earth's interior. The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers …

The Earth's mantle, a thick layer of semi-molten rock sandwiched between the crust and the core, constitutes the bulk of the planet's volume and mass. This dynamic zone drives key geological …

Aug 1, 2023 · There are two sections of the mantle: the upper mantle, which is more rigid and behaves elastically on short time scales, and the lower mantle, which is solid but flows on geological timescales.

Jan 9, 2026 · The mantle comprises that part of the Earth between the Mohorovičić and the Wiechert–Gutenberg discontinuities. It makes up 83 percent of the volume of the Earth and 67 …

The Earth’s mantle is the expansive layer situated between the planet’s thin outer crust and its central core. It begins approximately 7 to 35 kilometers (4.3 to 21.7 miles) beneath the surface, extending …

Jun 18, 2025 · The Earth’s mantle is the thickest layer, residing between the crust and the core, constituting about 84% of Earth’s volume. Composed predominantly of silicate rocks rich in iron and …

Jun 15, 2025 · It is the Earth’s mantle—a thick, complex layer that quietly shapes the surface of our planet and the life that depends on it. Without the mantle, Earth would be a lifeless rock in space, …

Below the crust is the mantle, a dense, hot layer of semi-solid rock approximately 2,900 km thick. The mantle, which contains more iron, magnesium, and calcium than the crust, is hotter and denser …

May 18, 2025 · The mantle is the thick layer of hot, solid rock between the Earth's crust and the molten iron core. It makes up the bulk of the Earth, accounting for two-thirds of the planet's mass.
