upper mantle
The upper mantle is the section of the Earth's mantle, extending from about 35 kilometers beneath the surface to about 670 kilometers beneath the surface. This area interacts directly with the Earth's crust and is primarily composed of peridotite, a rock rich in silicate minerals. The upper mantle is a layer of solid yet ductile rock that can flow and deform under pressure, which plays a key role in the movement of tectonic plates. Its temperature ranges from approximately 500 to 900 degrees Celsius at the top to around 1600 degrees Celsius at the bottom.
