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.

Answer and explanation

The heat budget of the earth

Practice questions

01 If atmospheric longwave absorption increases while solar input remains same what forcing direction will develop?

02 Why is heat budget called the budget of the Earth atmosphere system and not only of the surface?

03 In which condition can surface temperature remain relatively low even when incoming solar radiation is good?

04 If Earth's surface becomes warmer increase in outgoing longwave radiation is what type of response?

05 Why is water vapour feedback considered important in the heat budget?

06 Why is it wrong to treat net radiation and air temperature as the same in the heat budget?

07 Why can the local heat budget of a south facing slope and a north facing slope differ?

08 If incoming and outgoing energy are equal in the heat budget why does energy transfer still continue?

09 In which situation does maximum daytime temperature occur after the time of maximum insolation?

10 What is the main heat budget based reason for low diurnal temperature range in coastal areas?

11 In which situation can conduction have limited contribution in the heat budget?

12 Why is it said that heat budget is broader than only radiation budget?

13 If clouds are high and thin why can their effect differ from low thick clouds?

14 Why is the emissivity property of Earth's surface useful in the heat budget?

15 Why can two places at the same latitude have different heat budgets?

16 If an area has high albedo but also high atmospheric counter radiation why is temperature estimation difficult?

17 Why is understanding night temperature incomplete without longwave counter radiation?

18 Why is the atmosphere called not only a barrier but also a medium in the heat budget?

19 If outgoing longwave from the surface increases but the atmosphere absorbs more of it what happens to energy reaching space?

20 Thermal inertia of the climate system in heat budget is most linked with what?

21 In which condition can there be a time lag between radiative forcing and temperature response?

22 Why can it be wrong to directly equate absorbed shortwave by surface with emitted longwave?

23 If Earth's top of atmosphere energy balance is positive what is its deeper meaning?

24 Why are numbers in a heat budget diagram a model for understanding and not permanent truth for every place?

25 What is the most correct conclusion in an expert level explanation of heat budget?
