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. These extreme conditions create a transition zone in the upper mesosphere where minerals continuously change into various forms or pseudomorphs .
About 50 percent of the earth’s population lives less than 240 km from an ocean. In Japan, by contrast, 96 percent of the population lives less than 100 km from the ocean. We generally divide the earth into four spheres: (i) the atmosphere, (ii) the hydrosphere, (iii) the biosphere, and (iv) the lithosphere.
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.

This picture shows some of the features of 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.
2 paź 2019 · Mesosphere. Located between about 50 and 80 kilometers (31 and 50 miles) above Earth’s surface, the mesosphere gets progressively colder with altitude. In fact, the top of this layer is the coldest place found within the Earth system, with an average temperature of about minus 85 degrees Celsius (minus 120 degrees Fahrenheit).
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.
