Document Summary
Solid to liquid (requires heat) (4) radiation laws (a) stefan-boltzman law (i) the amount of energy the sun radiates is related to its temperature through the. The radiation in wm-2 is proportional to t4 (ii) wiens law: wavelength of the radiation is inversely related to objects temperature (iii) Kirchoffs law: states good aborbers are also good emitters and poor absorbers are also poor emitters. The earth surface plays a smaller role. the albedo is the ratio of reflected radiation to incoming radiation. Greenhouse effect. (1) ghg because water vapour or the atm is a selective absorber and emitter, its aborbs some of the energy. Thus increase the surface temp and it continues north become colder and tropics get warmer. Process of energy balance: transmission: radiation that passes through the atmosphere without being reflected, scattered and absorbed by the atmosphere available at the surface of the earth, energy balance.
