The '''homosphere''' is the portion of the [[earth|earth's]] [[atmosphere]], up to an altitude of about 50 [[mile]]s above sea level, in which there is continuous turbulent mixing, and hence the composition of the atmosphere is relatively constant; as opposed to the ''heterosphere'' or ''exosphere,'' the higher regions in which the composition becomes stratified.<ref>Wile, Dr. Jay L.
