Seasons kyun badalte hain?
Short mein jawab
Seasons isliye hote hain kyunki Earth ki axis jhuki hai aur Earth gol hai. June mein Northern Hemisphere Sun ki taraf jhukta hai, isliye wahan dhoop ghani hoti hai aur din 12 ghante se lambe hote hain: garmi. December mein wo door jhukta hai aur sardi aati hai. Usi samay Southern Hemisphere mein ulta season hota hai.

Jhuki hui Earth
Har saal hum seasons ke chakra se guzarte hain, aur garmi ke din sardi ke dinon se lambe hote hain. Dono Earth ke revolve karne ke tareeke se aate hain. Earth ki axis uski orbit ke hisaab se seedhi nahi, balki jhuki hui hai, aur Earth Sun ke poore chakkar mein yahi jhukaav, antariksh mein ek hi disha ki taraf, banaaye rakhti hai. Earth ke gol aakaar ke saath ye jhukaav hamein seasons deta hai.
June mein Northern Hemisphere Sun ki taraf jhuka hota hai aur Southern Hemisphere usse door. December mein ye ulat jaata hai. Isiliye uttar mein basa India June mein garmi jhelta hai, jabki dakshin mein basa Australia sardi.
Ghani dhoop
Mez pe torch pehle seedhe aur phir tirchhi chamkaao: tirchhi roshni bade hisse pe phail jaati hai aur dhundhli dikhti hai. Gol Earth pe dhoop bhi aise hi kaam karti hai. June mein Northern Hemisphere Sun ke zyaada saamne hota hai, isliye wahan dhoop ki ek maatra chhote hisse pe padti hai aur use zyaada garam karti hai. Southern Hemisphere mein wahi dhoop bade hisse pe phail kar kam garam karti hai.
Lambe din
Jhukaav din ki lambaai bhi badalta hai. June mein Northern Hemisphere ki jagahein har 24 ghante ke rotation ka aadhe se zyaada hissa Earth ke roshan aadhe mein bitaati hain, isliye unhe 12 ghante se zyaada dhoop milti hai. Zyaada ghani dhoop, zyaada der tak: yahi garmi hai. December mein uttar mein din chhote aur dhoop kamzor hoti hai, yaani sardi. Southern Hemisphere mein sab ulta hai: June mein sardi aur December mein garmi.
Solstice aur equinox
Northern Hemisphere mein sabse lamba din lagbhag 21 June ko hota hai, summer solstice. Uske baad din chhote hote jaate hain, sabse chhote din aur sabse lambi raat tak, lagbhag 22 December ko, winter solstice. Lagbhag 21 March aur 23 September ko din aur raat 12 12 ghante ke hote hain; ye spring aur autumn equinox hain.
Dhruv aur Equator
North Pole pe Sun March ke equinox ke aas paas ugta hai aur chhe mahine aasmaan mein rehta hai, September ke equinox ke aas paas doobta hai; phir chhe mahine andhera rehta hai. South Pole pe ulta hota hai. Equator pe hamesha lagbhag 12 ghante din aur 12 ghante raat hoti hai, aur dhoop ki taakat lagbhag nahi badalti, isliye Equator ke paas ke dakshini Indian rajyon mein seasons halke mehsoos hote hain. Samudr ki nazdeeki aur sthaaniya bhoogol bhi mausam ko aakaar dete hain.
Do galat wajahein
Log aksar kehte hain ki garmi tab aati hai jab jhuka hemisphere Sun ke paas hota hai, ya jab Earth ki thodi oval orbit use paas le aati hai. Dono mein doori ka badlaav bahut chhota hai. Asal mein Earth January ki shuruaat mein, uttar ki sardi ke dauraan, Sun ke sabse paas hoti hai.
Ye kyun zaroori hai
Seasons tay karte hain ki kisaan kab boyein, tyohaar kab aayein aur hum kaun se kapde pack karein. Earth kaise ghoomti aur chakkar lagaati hai, ye rotation aur revolution mein padho, aur surya grahan aur chandra grahan ke baare mein bhi.

Kerala mein seasons Punjab se halke kyun hote hain?
Jawab dekho
Jawab: Kerala Equator ke paas hai, jahan din saal bhar lagbhag 12 ghante ke rehte hain aur dhoop ki taakat kam badalti hai. Punjab zyaada uttar mein hai, isliye wahan garmi ke din bahut lambe aur sardi ke din bahut chhote hote hain, aur dhoop zyaada badalti hai. (Samudr aur sthaaniya bhoogol bhi mausam pe asar daalte hain.)

Agar Earth ki axis jhuki na hoti to seasons ka kya hota?
Jawab dekho
Jawab: Lagbhag koi season nahi hota. Har jagah saal bhar lagbhag 12 ghante din aur 12 ghante raat hoti, aur dhoop ki taakat lagbhag ek jaisi rehti, isliye har jagah saal bhar lagbhag ek jaisa mausam rehta.
Students ke sawal
Seasons kyun hote hain?
Kyunki Earth ki axis jhuki hui hai aur Earth gol hai. Apna jhukaav banaaye rakhte hue Sun ka chakkar lagaate samay har hemisphere baari baari Sun ki taraf jhukta hai. Jo hemisphere Sun ki taraf jhuka ho, use din mein 12 ghante se zyaada ghani dhoop milti hai aur wahan garmi hoti hai; doosre mein sardi.
Solstice aur equinox kya hain?
Northern Hemisphere mein sabse lamba din lagbhag 21 June ko hota hai, summer solstice, aur sabse chhota din lagbhag 22 December ko, winter solstice. Lagbhag 21 March aur 23 September ko din aur raat 12 12 ghante ke hote hain; ye spring aur autumn equinox hain.
Garmi mein din lambe kyun hote hain?
Garmi mein tumhara hemisphere Sun ki taraf jhuka hota hai, isliye Earth ke ghoomne pe wahan ki jagahein har rotation ka aadhe se zyaada hissa Earth ke roshan aadhe mein bitaati hain. Jaise June mein North Pole 24 ghante dhoop mein rehta hai aur uttar ki jagahon ko 12 ghante se zyaada din milta hai.
