Video narration
Baarish ke baad yeh pokhar gayab kahan ho jata hai? Dhoop padti hai, to pokhar ka paani garam hokar hawa mein uthta hai. Paani khatm nahin hota; vah adrishya jal-vaashp ban jata hai. Ise evaporation, yani vaashpeekaran, kehte hain. Upar ki hawa thandi hoti hai. Tab jal-vaashp chhoti-chhoti boondon mein badalkar judne lagti hai. Yahi condensation, yani sanghanan, baadal banati hai - baadal paani banane wali dibbiyaan nahin, balki boondon ka samooh hain. Jab boonden bhaari ho jaati hain, paani precipitation, yani varshan, ke roop mein dharti par lautata hai - baarish bankar. Phir paani mitti, pokharo, nadiyon, jheelon aur samudron mein ikattha hota hai. Dhoop use phir upar bhejti hai. Baarish ka paani naya bankar nahin aata. Yeh yaatra lagataar doharaati rahti hai. To pokhar gayab nahin hua tha. Uska paani roop badalkar yaatra kar raha tha - dharti se aasmaan, aur phir vaapas. Yahi jal-chakra hai.
