. At what height, a peak ionization occurs?

(a)At great heights

(b)Close to the earth

(c)At intermediate heights

(d)Height doesn’t matter

Best Answer


The density of atmosphere decreases with height. At great height, the solar radiation is intense but there are few molecules to be ionized. Close to the earth, even through the molecular communication is very high, the radiation intensity is low. So that ionization is again low. However, at some intermediate heights, there occurs a peak of ionization density.
