[@raghav490]

At around 4:35, you said that “it is conduction that is heating the surface of the earth step by step”, i.e., you said first it is mesosphere, then stratosphere, then troposphere. What written in NCERT is different I guess. Earth is heated just by direct radiation of earth (34%) and some radiation that it receives after scattering of radiations from atmosphere (17%). Conduction process then heats the layer of atmosphere nearest to earth and which transmits the heat to upper layers. Conduction takes place this way. And warm air also itself rises up. That is convection. My 2nd doubt : Whose contribution is more in heating the layers of atmosphere ? Conduction, convection or direct absorption of short wave radiation ?

[@kartiksahu9261]

you are right exactly my doubts

[@MM-ge5hr]

through insolation, 1st earth gets heated and then this heat is transferred to troposphere..etc. this is conduction. But he explained it something else.
