"ऋतु": अवतरणों में अंतर

[[Image:seasons.svg|frame|right|'''Fig. 1'''<br/>This diagram shows how the tilt of the Earth's axis aligns with incoming sunlight around the [[winter solstice]] of the Northern Hemisphere. Regardless of the time of day (i.e. the [[Earth]]'s rotation on its axis), the [[North Pole]] will be dark, and the [[South Pole]] will be illuminated; see also [[arctic winter]]. In addition to the density of [[Angle of incidence|incident]] light, the [[dissipation]] of light in the [[Earth's atmosphere|atmosphere]] is greater when it falls at a shallow angle.]]
