The mesosphere is the second major layer of Earth’s atmosphere, from about 50 to 85 kilometers (30 to 55 miles) above the surface. It sits directly above the stratosphere and below the thermosphere. It is characterized by extremely low air pressure and temperatures that can drop as low as -90 degrees Celsius (-130 degrees Fahrenheit), making ...
The mesosphere is the third highest layer of atmosphere and occupies the region above the stratosphere and below the thermosphere. This layer extends from the stratopause at an altitude of approximately 160,000 ft to the mesopause at approximately 260,000–80,000 ft above sea level. Temperatures drop with increasing altitude to the mesopause ...
Jun 13, 2024 · The mesosphere lies between the thermosphere and the stratosphere. “Meso” means middle, and this is the highest layer of the atmosphere in which the gases are all mixed up rather than being layered by their mass. The mesosphere is 22 miles (35 kilometers) thick. The air is still thin, so you wouldn’t be able to breathe up in the mesosphere.
NASA’s heliophysics researches the ionosphere-thermosphere-mesosphere region where our neutral atmosphere transitions into the ionized plasma of space. In this thin shell that surrounds our home planet, the atmosphere is in constant motion, shaped by the influence of both solar activity and changes in the lower atmosphere and in near-Earth space.
May 3, 2022 · The mesosphere is the coldest part of the atmosphere, with an average temperature of −85 °C (−120 °F; 190 K). Noctilucent clouds form in this layer. The informally-defined beginning of space begins in the mesosphere because there is just enough air to cause friction for objects approaching Earth from space.
Jan 2, 2024 · Both the stratosphere (next layer down) and the mesosphere are considered the middle atmosphere. The transition boundary which separates the mesosphere from the stratosphere is called the stratopause. Stratosphere. The stratosphere extends from from 4 -12 miles (6-20 km) above the Earth's surface to around 31 miles (50 km).
Jun 3, 2024 · Atmosphere - Stratosphere, Mesosphere, Ozone: The stratosphere is located above the troposphere and extends up to about 50 km (30 miles). Above the tropopause and the isothermal layer in the lower stratosphere, temperature increases with height. Temperatures as high as 0 °C (32 °F) are observed near the top of the stratosphere. The observed increase of temperature with height in the ...
