One special feature of the upper mantle is that it is mostly composed of solid rock but can exhibit some partial melting in certain regions, leading to magma formation. It plays a key role in tectonic plate movements and is involved in processes like convection that drive mantle dynamics.
upper mantle
The lower part of the mantle is called the "lower mantle" or "mesosphere", while the upper part of the mantle is referred to as the "upper mantle" or "asthenosphere".
The crust and upper mantle make up the earth.
The upper mantle and the lower mantle.
The upper mantle is harder than the lower mantle
The The crust and the uppermost layer of the mantle form the lithosphere. The asthenosphere, which is still in the upper mantle, is the next layer down.
The mantle is divided into the upper mantle and the lower mantle. The upper mantle lies directly beneath the Earth's crust and extends to a depth of about 410 miles. The lower mantle extends from the bottom of the upper mantle to a depth of about 1,800 miles.
The upper mantle is made of something called peridodite.
