The HI MOM! HI DAD! JASON AND AUTUMN BAKER! YEA, THIS IS FOR YOU!!! '''stratosphere''' {{IPAc-en|ˈ|s|t|r|æ|t|ə|s|f|ɪər}} is the second major layer of [[Earth's atmosphere]], just above the [[troposphere]], and below the [[mesosphere]]. It is [[Atmospheric stratification|stratified]] in temperature, with warmer layers higher up and cooler layers farther down. This is in contrast to the troposphere near the Earth's surface, which is cooler higher up and warmer farther down. The border of the troposphere and stratosphere, the [[tropopause]], is marked by where this inversion begins, which in terms of [[atmospheric thermodynamics]] is the [[equilibrium level]]. At moderate latitudes the stratosphere is situated between about {{convert|10|-|13|km|sigfig=1|ft mi|abbr=on}} and {{convert|50|km|sigfig=2|ft mi|abbr=on}} [[altitude]] above the surface, while at the [[geographical pole|poles]] it starts at about {{convert|8|km|sigfig=1|ft mi|abbr=on}} altitude, and near the [[equator]] it may start at altitudes as high as {{convert|18|km|sigfig=2|ft mi|abbr=on}}.
