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 lower mantle is in a solid state of matter. It is composed mainly of silicate minerals, which can withstand high pressure and temperature, maintaining a solid form despite the intense conditions present at that depth within the Earth.

The upper mantle is a solid layer of rock located beneath the Earth's crust. It is part of the Earth's mantle and extends from the base of the crust to a depth of about 660 kilometers. The upper mantle is mostly composed of peridotite, a dense rock made up of minerals like olivine and pyroxene.
The crust and upper mantle make up the earth.
