Earth's upper mantle
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 1,200 K (930 °C; 1,700 °F) at the boundary with the lower mantle. Upper mantle material that has com… WebMay 22, 2024 · May 22, 2024 In grade-school science textbooks, Earth's mantle is usually shown in a yellow-to-orange gradient, a nebulously defined layer between the crust and the core. To geologists, the mantle is much more than that. It's a region somewhere between the cold crust and the bright heat of the core.

WebNov 11, 2024 · Starting at the center, Earth is composed of four distinct layers. They are, from deepest to shallowest, the inner core, the outer core, the mantle and the crust. … WebJul 11, 2024 · Earth’s mantle is the thick layer of silicate rock between Earth’s crust and its molten core, making up about 84% of our planet’s volume. The mantle is predominantly solid but, on geologic time scales, it behaves as a viscous fluid — as difficult to stir and mix as a pot of caramel.
WebThe upper mantle is the region 40 - 410 km depth, (T = 930 - 1785 K, P = 1.122 - 13.4 GPa) while the transition zone is the region 410 - 670 km, (T = 1785 - 1950 K, P = 13.4 - 23.83 GPa). In general, the deeper in the earth, the greater the density of the minerals.
WebIn geochemistry, the primitive mantle (also known as the bulk silicate Earth) is the chemical composition of the Earth's mantle during the developmental stage between core-mantle differentiation and the formation of early continental crust. The chemical composition of the primitive mantle contains characteristics of both the crust and the mantle. WebFeb 15, 2024 · Popular representations of the inner Earth depict the mantle as a yellow or red substance that appears to ooze across the planet. Much to the contrary, the upper mantle is a solid rock that is mostly greenish in color. It largely consists of a 60/40 blend of olivine (also known as peridot) and pyroxene.
