Heating and cooling of the atmosphere

In this Class 11 Geography topic, students learn how the atmosphere is heated and cooled through incoming solar radiation and outgoing terrestrial radiation. The lesson explains Earth’s heat balance and the roles of conduction, convection, advection, and latent heat in transferring energy through the atmosphere. Students also examine how land and water surfaces, cloud cover, humidity, and atmospheric circulation influence temperature patterns and help produce differences between places and times.
