Atmosphere of Earth layers because a larger atmospheric weight sits on top of the troposphere and causes it to be most severely compressed. Fifty percent of the total mass of the atmosphere is located in the lower of the troposphere. Nearly all atmospheric water vapor or moisture is found in the troposphere, so it is the layer where most of Earth's weather takes place. It has basically all the weather-associated cloud genus types generated by active wind circulation, although very tall cumulonimbus thunder clouds can penetrate the tropopause from below and rise into the lower part of the stratosphere.

Lowest temperature recorded on Earth Lowest temperature recorded on Earth The lowest natural temperature ever directly recorded at ground level on Earth is at the Soviet Vostok Station in Antarctica on July 21, 1983 by ground measurements. On August 10, 2010, satellite observations showed a surface temperature of at , along a ridge between Dome Argus and Dome Fuji, at elevation. The result was reported at the 46th annual meeting of the American Geophysical Union in San Francisco in December 2013; it is a provisional figure, and may be subject to revision. The value is not listed as the record lowest temperature as it was
