Piyush , asked a question
Subject: Physics , asked on 10/12/12

why does electrical conductivity of earth's atmosphere increase with latitude?is it because its density goes on decreasing?

EXPERT ANSWER

Yes, the conductivity does increase with altitude, let's see why...

As the altitude increases the atmosphere gets thinner and thus less dense. This would mean that less air particles are present the higher up we go and thus atmospheric ions have more room to move about and that to with greater speed. This is would result in increasing conductivity.

WITH INCREASE IN LATITUDE the ionosphere becomes more dense and thus increase in conductivity
