The transition boundary between the troposphere and the layer above is called the tropopause. Together the tropopause and the troposphere are known as the lower atmosphere. Stratosphere. The Stratosphere extends from the tropopause up to 31 miles above the Earth's surface.This layer holds 19 percent of the atmosphere's gases but very little water vapor.Temperature increases with height as radiation is increasingly absorbed by oxygen molecules leading to the formation of Ozone.tratosphere.
