* Mesosphere is a layer in the Earth's atmosphere, located above the stratosphere and below the thermosphere. It is characterized by decreasing temperature with increasing altitude.
* Mantle is a layer of the Earth's interior, located between the crust and the core. It is composed primarily of silicate minerals.
Therefore, it is incorrect to talk about the "composition of the mesosphere mantle".
Here are the compositions of the two layers:
* Mesosphere: The mesosphere is primarily composed of nitrogen and oxygen, with trace amounts of other gases like carbon dioxide, argon, and helium.
* Mantle: The mantle is composed primarily of silicate minerals like olivine and pyroxene. It also contains smaller amounts of iron, magnesium, calcium, and aluminum.
If you're interested in learning more about either of these layers, please let me know!
