heterosphere In meteorology, the upper of two portions of the atmosphere as distinguished by the general homogeneity of their composition (the other portion is the homosphere); it begins at 80 to 100 kilometers above the earth, closely coinciding with the ionosphere and the thermosphere, and is characterized by variation in composition and mean mol

The upper layer in a two part classification of the atmosphere based on the general homogeneity of chemical composition. In this layer, oxygen atoms and nitrogen molecules dominate and remain constant in their relative quantities. The heterosphere extends upward from a height of 80 to 100 kilometers depending on latitude. Below this layer is the ho
