Web4 nov. 2005 · A third layer containing metallic ions has been predicted to form between 80 and 100 km in altitude ( 10 – 12 ). The source of these ions is charge exchange of Fe and Mg derived from ablation from meteorites entering the martian atmosphere. This phenomenon is well known in Earth's ionosphere at an altitude of 95 to 100 km ( 13 ). WebGenerally, the ionosphere consists of 4 different layers namely D, E, F 1, and F 2. These layers are present at different heights from the surface of the earth. Basically the ionosphere is said to be extended from 60 to 400 Km from the surface of the earth. The figure below represents the structure of the ionosphere:
