The heat budget of the earth

पृथ्वी का ऊष्मा बजट

Class 11 Geography explores the heat budget of the Earth as the balance between incoming solar radiation and outgoing terrestrial radiation. Students learn how the atmosphere, land, oceans, clouds, and ice reflect, absorb, store, and redistribute heat, and why the Earth’s average temperature remains broadly stable. The topic connects this balance with the greenhouse effect, latitudinal differences in heating, and the movement of heat through the atmosphere and oceans.
