Layer of the atmosphere between 30 and 50 mi (50 and 80 km) in altitude, characterized by decreasing temperatures with increasing altitude.
The region of the atmosphere lying above the stratosphere and extending from the stratopause at about 50 km height to the mesopause at 85–95 km. The mesosphere is characterized by decreasing temperature with increasing height, reflecting the decreasing absorption of solar ultraviolet radiation by ozone. Many features of the mesosphere remain poorly understood since in situ measurements are difficult. The region is too high for balloon operations and too low for satellites to orbit. Rockets, while useful, usually travel too rapidly through the region to produce reliable measurements. See atmospheric shell.
The atmospheric shell between about 20 km and about 70 to 80 km, extending from the top of the stratosphere (the stratopause) to the upper temperature minimum that defines the mesopause (the base of the thermosphere).
That portion of the Earth's atmosphere located 34 to 50 miles (55 to 80 kilometers) up, where temperature decreases with increasing altitude
Region of the atmosphere, between approximately 50 to 100 km, in which temperature decreases with altitude.
The cooler layer of atmosphere overlying the stratosphere.
Third layer of the atmosphere; found above the stratosphere. Compare stratosphere, troposphere.
Intermediate atmospheric layer above the stratosphere extending approximately between 30 and 100 kilometers above Earth's surface.
Layer of the atmosphere which is 50 km to 80 km above sea level. The mesosphere is much colder than the stratosphere that forms its lower boundary. In the summer, it can reach -140 degrees C, the lowest natural temperature on Earth.
Belt of atmosphere, just above the stratosphere, from 30-50 miles(50-80km) above the earth.
The third layer of the atmosphere above Earth's surface, generally found between altitudes of 50 km and 80-85 km and characterized by temperature decreasing with altitude.
Region of Earth's atmosphere lying between the stratosphere and the ionosphere, 50-80 km above Earth's surface.
Literally, the middle sphere -- the middle portion of the atmosphere, between the stratosphere (below), and the thermosphere (above). In the Earth's atmosphere, a region where the temperature gradually declines at greater and greater heights.
The third major atmospheric level extending from the top of the stratosphere to the bottom of the thermosphere. The temperature characteristically decreases with increasing attitude.
the layer of earth's atmosphere extending from the stratosphere to the thermosphere and temperature decreases as altitude increases
The layer of the Earthâ€(tm)s atmosphere that lies between the stratosphere and the thermosphere. It stretches 50-85 km above our planetâ€(tm)s surface.
Region of the atmosphere between approximately 50 and 85 km. Source: EPO.
The layer of the atmosphere directly above the Stratosphere ranging from 31 to 50 miles (50 to 80 km) above the earth's surface.
Sometimes used to denote the middle atmosphere, between the stratosphere and the ionosphere.
The region of the earth's atmosphere between the stratopause at the top of stratosphere (at an altitude of approximately 50 km) and mesopause, just below the thermosphere (70 to 80 km altitude) where the temperature decreases rapidly with height.
The layer of the atmosphere lying between 50 - 100 km altitude. More Information.
Literally the 'middle sphere' of the Earth, the mesosphere comprises the mantle below the asthenosphere and the core of the Earth.
The atmospheric layer between the stratosphere and the thermosphere.
Region of the Earth's atmosphere between 50 and 100 km where the temperature falls rapidly.
Atmospheric layer found between the stratosphere and the thermosphere. Usually located at an average altitude of 50 to 80 kilometers above the Earth's surface. Air temperature within the mesosphere decreases with increasing altitude.
The atmospheric layer above the stratosphere and below the thermosphere; the middle layer; temperatures are usually very low.
the region of the atmosphere between about 50 kilometers (31 miles) and 80-85 kilometers (50-53 miles), extending from the top of the stratosphere to the upper temperature minimum; it is characterized by a broad temperature maximum (near 0 degrees Celsius) at its base, from which the temperature decreases to a minimum (about -90 degrees Celsius) at the mesopause level.

the atmospheric layer between the stratosphere and the ionosphere.
The layer of the atmosphere located between the stratosphere and the ionosphere, where temperatures drop rapidly with increasing height. It extends between 31 and 50 miles (17 to 80 kilometers) above the earth's surface.
The layer of the Earth's atmosphere above the stratosphere.
1. The lowermost portion of the mantle. 2. The layer of the atmosphere above the stratosphere, where temperature decreases with altitude.
The mesosphere is characterized by temperatures that quickly decrease as height increases. The mesosphere extends from between 31 and 50 miles (17 to 80 kilometers) above the earth's surface.
The mesosphere refers to the lower mantle in the region between the asthenosphere and the outer core. This region, also called the lower mantle, is named in order to differentiate from the lithosphere and the asthenosphere portions of the mantle. It is more solid than the asthenosphere due to higher pressures.
