mesosphere.
mesopause
thermosphere
convection zone.
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!
It is actually not hot, it is the coldest layer of our atmosphere. (Sometimes, the tempetures can get up to -95 degrees Celsius)!
Mesosphere
MESOSPHERE is the coldest layer of the atmosphere.
The Antarctic zone has the coldest winters.
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 frigid zone is the coldest because they receive extremely slanting sunrays
Coolest or coldest?? The coldest region is definitely the Antarctic. Antarctica to be exact.
thermosphere
The Frigid zone
Greenland
The coldest layer is actually around the Mesopause -- where the Mesosphere and thermosphere meet. (\ /) (^-^) (U U) u u
