Web23 mrt. 2024 · The mantle is the thickest section of the Earth at approximately 2,900 kilometres. The upper part of the mantle is called the asthenosphere. It is made up of semi- molten rock called magma. The asthenosphere is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement and isostatic adjustments. It is composed of peridotite, a rock containing mostly the minerals olivine and pyroxene. The lithosphere-asthenosphere boundary is conventionally taken at the 1,300 °C (2,370 °F) isotherm. Below this temperature (closer to the surface) the mantle … chip customizer software
