WebThe ionosphere of Mars is formed by photo-ionisation of CO 2 in its atmosphere. Mars’ lack of a dynamo magnetic field leads to a much more direct interaction of the ionosphere with the solar wind. Mars does have a weak, spatially varied crustal magnetic field, which in places is in fact strong enough to dominate the interaction with the solar wind, forming so … song of the usaWeb6 nov. 2014 · Ionosphere responses to acoustic waves appear first above epicentres 10–15 min after the main shock as fast ∼0.8–1.0 m s −1.
