The mesosphere is the coldest layer. In the outer mesosphere, temperatures approach -90 degrees Celsius.
However, a thermometer would measure the thermosphere to be well below 0 degrees Celsius. The thermosphere is actually very hot. It can get up to 1, 800 degrees Celsius. You would not feel that warmth though because temperature is the average amount of energy in motion of each molecule of a substance. The gas molecules in the thermosphere move very rapidly, so the temperature is very high. The molecules are spread very far apart and there are not enough of them to collide with the thermometer and warm it very much.
If you are researching this, all I can tell you is to not believe what other people are saying about the fact that the higher you get, the colder it is because the evidence is perfectly clear that it is not true.

From Wikipedia:Temperature decreases with height in the mesosphere. The mesopause, the temperature minimum that marks the top of the mesosphere, is the coldest place on Earth and has an average temperature around −100 °C (−148.0 °F; 173.1 K)the mesosphere is the coldest layer in the atmosphere. It contains the ozone.OK!! the answer above is incorrect the coldest layer in the atmosphere is the Mesopause its the thin layer between the Mesosphere and Thermosphere. Also the Ozone is in the Stratosphere.Actually its correct because the mesopause is a part of the mesosphere....ok the 1st and 3rd answers are wrong! i should know im learning this in my 7TH GRADE SCIENCE CLASS! the ozone is in the stratosphere, the second closest layer to the earth. STUPIDS!
Well, mesosphere is the middle layer of the atmosphere; also the coldest temperature of all the layers is here.
It is actually not hot, it is the coldest layer of our atmosphere. (Sometimes, the tempetures can get up to -95 degrees Celsius)!
The hottest layer is the mesosphere that is why meteors and asteroids burn in this layer .
mesosphere.
The coldest layer is actually around the Mesopause -- where the Mesosphere and thermosphere meet. (\ /) (^-^) (U U) u u
MESOSPHERE is the coldest layer of the atmosphere.
The mesosphere is the layer of the atmosphere that exists between the stratosphere and the thermosphere. It contains the coldest parts of the Earth's atmosphere, reaching temperature depths of -90°C.

The mesosphere is the coldest layer of the earth's atmosphere.
The Mesosphere.
yes
Mesosphere
It's the coldest layer of the atmosphere.
The coldest layer of the atmosphere is the exosphere (space). If you were to not count the exosphere, the coldest layer would be the mesosphere.
