What is the mesosphere made from?

The mesosphere is composed primarily of solid and liquid rock, specifically silicate minerals, located beneath the Earth's crust and above the outer core. It consists of a mixture of magnesium silicate minerals, such as olivine and pyroxene, along with various other compounds. The temperature and pressure in this layer increase with depth, contributing to the physical state of the materials found there. The mesosphere plays a crucial role in the Earth's geology, influencing mantle convection and plate tectonics.
