Question
Is the lithosphere the same composition as the mesosphere

No, the lithosphere and the mesosphere are not composed of the same materials, and they occupy different layers of the Earth with distinct characteristics.
1. **Lithosphere**: The lithosphere is the outermost layer of the Earth and includes the crust and the uppermost part of the mantle. It is solid and relatively rigid. The lithosphere is primarily composed of silicate minerals, including granite in continental crust and basalt in oceanic crust.
2. **Mesosphere**: The term "mesosphere" can refer to two different contexts in Earth science. In the context of the Earth's interior, the mesosphere refers to the lower part of the mantle, situated beneath the asthenosphere (the semi-fluid layer) and above the outer core. The mesosphere is made up of solid silicate minerals that can behave plastically over long geological timescales, and it is subjected to high temperatures and pressures.
So, while both layers consist of silicate minerals, the conditions (temperature, pressure) and the physical states (rigid in the lithosphere, more plastic in the mesosphere) differ significantly.
