Hi, can you tell me about why treelines exist? My friend who lives in the mountains says trees just don’t grow above a certain altitude. Is that true? What makes it happen?

ek ped kii rekha un sthitiyon ke kinare ko chihnit karti he jisamen ped majbooti se badhane main sakasham hote hai.yah aksar oonchai kaa ek kaary hota he, lekin yah vishesh rup se taapmaana, snopac, hawa or/yaa uplabdh nami dwaara paribhaashit kiya jaataa he.pahari kshetron main jo sthaayee snopac ko banaae rakhane ke liye paryaapt lanbaa he, ped kii rekha aamtaur par sthaayee barf se 300 se 1000 meter ke bich hoti he or lagbhag iske samanaantar chalati he.

zyaadaatar maamalon main, ped kii rekha ko ausat mausami taapmaana dwaara paribhaashit kiya jaataa he.yahaan tak ki conifer ke ped bhi badhane ke liye band ho jaaenge jahaan mausami matlab taapmaana 6 degree celsius (43 farenheit) se kam he.unhen safaltaapurvak badhane ke liye us taapmaana se upar lagbhag 94 dinon ke vikaas ke samay kii aavashyaktaa hoti he.

prithvi ke kuch kshetra dhruvon ke kaaphi kareeb hai ki ve samudr-str kii oonchaai par bhi vruddhi-tay taapmaana par paryaapt samay nahin bitaate hai.in kshetron (tundra or antarctic, udhaaharan ke liye) ko ped kii rekha ke upar bhi mana ja saktaa he.

anya kaarak ped kii rekhaaen bhi bana sakate hai.hawa ankuron ko ek paripakv oonchai tak badhane se roak sakati he or is prakaar jangalon ke vikaas ko roak sakati he.kuch hawa vaale kshetra (vishesh rup se samudr taton ke saath) upyog karne yogya mitti se chin jate hai, isliye ve ped ke vikaas kaa samarthan nahin kar sakate hai.agar bahut kam varsha he jo pedo ko badhane se bhi rakhegi.

loging jaisi maanviya gatividhiyaan kritrim ped line banaati hai, haalanki ye line sthaayee nahin hai.keval lagaataar maanavajanit (maanav-kud) tree line parivartan jalwaayu parivartan ke prabhaavon ke madhyam se aate hai.
