IONOSPHERE is the layer which is present at definite height under exosphere where as exosphere is extended to outer space . Many things take place ie aurora borilis take place in ionosphere and many things like satellites fly in exosphere . read more
The ionosphere is the lower portion of the thermosphere. The northern and southern lights (aurora) are generated within the ionosphere. I think my major professors might frown at this simplistic explanation. read more
