Main Body
Processes maintaining heat balance.
1Greenhouse gas effect: Certain gases are trapped like Greenhouse and increase the temperature of atmosphere [eg] CO2.
2Reflection by earth: long wave radiations get reflected back by earth's surface.
3Ozone layer: Ozone protects earth's atmosphere from Carcinogenic UV C rays
4Transparency in atmosphere: atmosphere is fully transparent to short-wave radiations
5Role of moisture: brings rainfall and thus have moderating effect on earth's heat
6Cloud formation: leads to precipitation
7Wind speed: Helps to moderate down the temperature of a region.
8Ocean temperature: Sea-surface temperature is a causative factor for weather phenomena.
