The mesosphere, sometimes known as the lower mantle, is more rigid and immobile than the asthenosphere. Located at a depth of approximately 410 and 660 km below the earth’s surface, the mesosphere is subjected to very high pressures and temperatures.
1 sie 2023 · Below the asthenosphere and extending to about 2,900 km is the mesosphere or lower mantle. The mesosphere is a region of strong, rigid rocks that deform slowly under the intense heat and pressure. It’s composed of silicate minerals that change in structure with depth due to increasing pressure.

The mesosphere (/ ˈ m ɛ s ə s f ɪər, ˈ m ɛ z-, ˈ m iː s ə-,-z ə-/; [1] from Ancient Greek μέσος (mésos) 'middle' and -sphere) is the third layer of the atmosphere, directly above the stratosphere and directly below the thermosphere. In the mesosphere, temperature decreases as altitude increases.
The mesosphere is a layer of Earth's atmosphere. The mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet. Temperature decreases with height throughout the mesosphere.
Earth's mesosphere extends from about 50 to 85 km (31 to 53 miles) above our planet. The stratosphere is the atmospheric layer below it, while the thermosphere is above. The upper boundary of the mesosphere is the mesopause, while its lower boundary is the stratopause.
The Earth has a complex structure: a solid inner core surrounded by a liquid outer core surrounded by a solid mantle and a thin crust. The Earth's crust comprises many tectonic plates and is susceptible to earthquakes, volcanic eruptions, and other tectonic activity.
