If two planets receive the same sunlight but have different atmospheric compositions, why might their surface temperatures differ significantly?
دو سیاروں پر یکساں دھوپ پڑے مگر فضائی ترکیب مختلف ہو تو سطحی درجہ حرارت میں نمایاں فرق کیوں ہوسکتا ہے؟
Solution & explanation
Atmospheric absorption, greenhouse strength, clouds, albedo and heat transport alter energy balance. Equal incoming flux does not imply equal absorbed energy or outgoing infrared at a given surface temperature.
