The mesosphere starts at 50 km (31 miles) above Earth's surface and goes up to 85 km (53 miles) high. As you get higher up in the mesosphere, the temperature gets colder. The top of the mesosphere ...

en.wikipedia.org/wiki/Mesosphere

The mesosphere (/ ˈ m ɛ s oʊ s f ɪər /; from Greek mesos, "middle") is the third major layer of the Earth's 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 above the stratosphere layer. The layer above the mesosphere is called the thermosphere. The mesosphere starts at 50 km (31 miles) above Earth's surface and goes up to 85 km (53 miles) high. As you get higher up in the mesosphere ...

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. The coldest temperatures in Earth's atmosphere, about -90° C (-130° F), are found near the top of this layer.

The mesosphere is one of five layers of the atmosphere surrounding the planet earth. The other four layers include the troposphere, stratosphere, thermosphere, and exosphere. The mesosphere is located approximately 50km from the earth's surface and extends as far as 85km from the earth's surface. The mesosphere is located above the stratosphere and below the thermosphere.

The top of the mesosphere is the coldest place in the atmosphere, with temperatures falling as low as -225°F (about -143°C). The freezing temperatures cause ice to form on the rock and metal particles in the atmosphere, which can then form what are known as noctilucent clouds.

The thermosphere is directly above the mesosphere and below the exosphere. It extends from about 90 km (56 miles) to between 500 and 1,000 km (311 to 621 miles) above our planet. Temperatures climb sharply in the lower thermosphere (below 200 to 300 km altitude), then level off and hold fairly steady with increasing altitude above that height.

Nitrogen and oxygen are the gases that make up the mesosphere. The temperature in the mesosphere is cold enough to create ice clouds that are visible from Earth. Electrical charges within the mesosphere are also sometimes seen on Earth. The mesosphere is the third layer of the earth's atmosphere, where most meteors burn up.

The Mesosphere has the lowest temperature of the layers of Earth's atmosphere because Temperature decreases with height in the mesosphere. The mesopause, the temperature minimum that marks the top ...

This generates heat; ironically, the mesosphere is the coldest part of the atmosphere. When a meteor begins to enter the mesosphere, it immediately bumps into molecules of the Earth's coldest atmosphere and scrapes against them, causing friction and rapidly generating heat due to the speed of the meteor.
