Upper Mantle. Temperature: 1,400°C – 3,000°C State: liquid / solid Composition: iron, oxygen, silicon, magnesium and aluminium. This layer is up to 670km below the Earth’s surface. The lower part of the upper mantle is made from both solid and melted rock (liquid), while the rock in the upper region is stiffer, because it’s cooler. Crust
30 Απρ 2024 · The temperature of the mantle varies greatly, from 1000°C (1832°F) near its boundary with the crust, to 3700°C (6692°F) near its boundary with the core. In the mantle, heat and pressure generally increase with depth. The geothermal gradient is a measurement of this increase.
The inner core and the outer Core. The core is the Earth's source of internal heat. This is because it contains radioactive materials that release heat as they break down into more stable materials. The inner core has a temperature of up to 4 000℃ and the outer core has a temperature of up to 3 600℃.
The Earth has a layered structure made up of crust, mantle, outer core and inner core. Find out more in this BBC Bitesize guide for students aged 11-14.
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 ...

Earth is divided into four layers: the inner core, the outer core, the mantle and the crust. The solid inner core is made of iron and nickel and is as hot as the surface of the sun.
