The hottest layer is the mesosphere that is why meteors and asteroids burn in this layer .
The three coldest planets (average surface temperatures) are Saturn, Uranus and Neptune.
thermosphere
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!
Tropopause
the troposphere
MESOSPHERE is the coldest layer of the atmosphere.
-119 is the coldest of the temperatures listed.
The mesosphere is the coldest layer of the earth's 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 Exosphere
mesosphere
The coldest layer is actually around the Mesopause -- where the Mesosphere and thermosphere meet. (\ /) (^-^) (U U) u u

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.
Yes, the average temperatures are -184.C.
The crust is the coldest geologic layer.
