प्रश्न
Most of the water that falls on the land as rain and snow, sooner or later goes back to a sea or an ocean. Explain how it happens?
उत्तर
Rain and snow eventually return to a sea or ocean because as snow melts from the sun, the water runs into a river, which also receives rainwater directly. All of these rivers flow for a considerable distance before joining a sea or ocean. The water that evaporates from the seas and oceans is returned to them.
