2024年4月30日 · 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.
Mantle (geology) - Wikipedia
The Earth's mantle is a layer of silicate rock between the crust and the outer core. Its mass of 4.01 × 10 24 kg is 67% the mass of the Earth. [1] It has a thickness of 2,900 kilometres (1,800 mi) [1] making up about 84% of Earth's volume. It is predominantly solid, but in geological time it behaves as a viscous fluid

2023年4月8日 · The mantle of the Earth is a stratum of silicate rock that exists between the crust and the outer core. It has a mass of 4.01 1024 kg and thus accounts for 67% of Earth’s bulk. The mantle starts at the Mohorovicic discontinuity and extends down to the core-mantle boundary, also known as the Gutenberg discontinuity.
Mantle of the Earth – Geology In
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 - Simple English Wikipedia, the free encyclopedia
The Earth's mantle has two layers. There is a rigid upper layer and a softer layer. It is between the Earth's crust and the Earth's outer core. [1] [2]
3.1: Earth’s Layers- Crust, Mantle, and Core
2024年8月22日 · 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. Figure 3.3 Earth’s interior.

Upper mantle - Wikipedia
The upper mantle of Earth is a very thick layer of rock inside the planet, which begins just beneath the crust (at about 10 km (6.2 mi) under the oceans and about 35 km (22 mi) under the continents) and ends at the top of the lower mantle at 670 km (420 mi). Temperatures range from approximately 500 K (227 °C; 440 °F) at the upper boundary with the crust to approximately …
