Har din Suraj samudra, nadiyon, jheelon aur geeli mitti aur patton ka paani garam karta hai. Bahut saara paani vashpit hokar adrishya bhaap banke upar uthta hai.
Zameen se bahut upar hawa thandi hoti hai. Bhaap chhote dhool kanon par sanghanit hokar anginat boondein banti hai: baadal. Jab boondein judkar tairne ke liye bahut bhaari ho jaati hain, baarish banke girti hain (bahut thand mein barf aur ole).
Baarish ka paani nadiyon-samudra mein bahta hai, aur zameen mein bhoojal banke samaata hai, jise hum kuon se nikaalte hain. Phir yaatra dobara shuru. Ye kabhi na khatam hone wali yaatra jal chakra hai. Wahi paani laakhon saal se ghoom raha hai, isliye ise saaf rakhna zaroori hai!

- Paani ki yaatra kram mein lagao.
Yaad rakho
- Vashpan, sanghanan aur baarish jal chakra mein paani ko ghumaate hain.
- Kuch baarish ka paani bhoojal banta hai; paani saaf rakhna zaroori hai.
Quick check
Baadal kis se bane hain?
- chhoti paani ki boondein (ya barf ke kan)
- dhuaan
- rui
- sirf dhool
Answer
chhoti paani ki boondein (ya barf ke kan). Bhaap oonchai par chhoti boondon mein sanghanit hokar baadal banti hai.
Socho
Agar ek saal samudra se bilkul vashpan na ho, to baarish aur nadiyon ka kya hoga?
Ek answer
Vashpan na ho to bahut kam bhaap upar jaayegi, to kam baadal banenge aur lagbhag baarish nahi hogi. Nadiyaan aur kuen dheere-dheere sookh jaayenge.
