The '''Stratosphere''' is the region of the atmosphere that spans altitudes of 4 to 30 miles,<ref>Wile, Dr. Jay L. ''Exploring Creation With Physical Science''. Apologia Educational Ministries, Inc. 1999, 2000</ref> or more narrowly from 8 to 12 miles in altitude.

The '''stratosphere''' is the layer of the Earth's atmosphere that exists above the [[troposphere]].  On average, the bottom of the stratosphere is at a height of about 12 km and the top of the stratosphere (called the ''stratopause'') is around 50 km.<ref>Wile, Dr. Jay L. ''Exploring Creation With Physical Science''. Apologia Educational Ministries, Inc. 1999, 2000</ref> The layer above the stratosphere is the [[mesosphere]].

 

Temperature increases with height in the stratosphere. This causes the stratosphere to be buoyantly stable, which suppresses vertical motions.

 

The [[ozone layer]] is in the upper part of the stratosphere.
