A mantle is a layer inside a planetary body bounded below by a core and above by a crust. Mantles are made of rock or ices , and are generally the largest and most massive layer of the planetary body.

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 67% of the mass of Earth. [1] It has a thickness of 2,900 kilometers (1,800 mi) [1] making up about 46% of Earth's radius and 84% of Earth's volume.

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 (1,802 miles) thick, and makes up a whopping 84 percent of Earth’s total volume.

Aug 22, 2024 · Mantle. Lithosphere; Asthenosphere; D” Core; Earth consists of three main layers: the crust, the mantle, and the core (Figure 3.3). The core accounts for almost half of Earth’s radius, but it amounts to only 16.1% of Earth’s volume. Most of Earth’s volume (82.5%) is its mantle, and only a small fraction (1.4%) is its crust.

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 processes, including plate tectonics and volcanic activity.

Earth's mantle is thought to be composed mainly of olivine-rich rock. It has different temperatures at different depths. The temperature is lowest immediately beneath the crust and increases with depth.

In Earth's interior, the mantle is a rocky layer directly beneath the crust and above the outer core. The mantle makes up about 70 percent of Earth's volume and overlies the Earth's iron-rich core, which occupies about 30 percent of Earth's volume.

Dec 8, 2023 · Mantle: The mantle is located beneath the Earth’s crust and extends to a depth of about 1,800 miles (2,900 kilometers). It is the thickest layer of the Earth. The mantle is composed of solid rock, primarily silicate minerals. Although it is solid, the mantle behaves like a very viscous or plastic material over geological timescales.

The lower mantle, historically also known as the mesosphere, represents approximately 56% of Earth's total volume, and is the region from 660 to 2900 km below Earth's surface; between the transition zone and the outer core. [1] .

A mantle is a layer inside a planetary body that is between the core and the crust of a planetary body. Mantles are made of rock or ices. They are generally the largest layer of the planetary body. All terrestrial planets, all ice giants, a number of asteroids, and some moons have mantles.
