Bo nazardoshti nuqtai nazari oid ba paydoishi sistemai sitoraho zikryofta dar borai tarkibi elementhoi atmosferai nakhustin khulosa barovardan mumkin ast.
Aqidahoi hozira niz ba ziyod mavjud budani miqdori gidrogen dar kayhon va oftob asos yoftaand. Dar jadvali 2.2. tarkibi elementhoi moddai sitora va oftob ovarda shudaast.
Takhmin meravad, ki atmosferai avvalini zamin harorati balandash miyona bud; to gumshavii joziba (gravitatsiya) qismi ziyodi onro gidrogen tashkil medod va tarkibi asosii molekulaviash az metan, ob va ammiak iborat budaast.
Agar tarkibi elementhoi moddai sitoraro ba tarkibi Zamini imruza va organizmhoi zindai on muqoisa kunem, khele ajib menamoyad.
Dar tabiati gayrizinda az hama elementi mamul gidrogen va geliy buda, pas az onho karbon, nitrogen, silitsiy va magniy meistand. Qayd kardan lozim ast, ki organizmi zindai biosferai rui Zamin niz asosan az gidrogen, oksigen, karbon va nitrogen iborat meboshad.
Atmosferai avvalini Zamin dar natijai ravandhoi gunogun, qabl az hama, ba tavri diffuzi baromada raftani gidrogen va geliy, ki qismi ziyodi onro tashkil medodand, metavonist tagyir yobad. In elementho az hama sabuktarand va boyad az atmosfera gum meshudand, zero maydoni jozibai sayyorai mo dar muqoisa bo maydoni jozibai sayyorahoi azim khurd ast. Qismi ziyodi atmosferai avvalini zamin boyad dar yak muddati kutoh gum meshud. Az in sabab, takhmin meravad, ki bisyor gazhoi avvalini atmosferai Zamin gazhoe budand,ki dar qari Zamin nigoh doshta meshudand va dar natijai tadrijan garm shudani jinshoi on az sari nav judo shudaand.
Dar atmosferai avvalini Zamin ehtimol hamon moddahoi organikie vujud doshtand, ki holo dar tarkibi kometaho mushohida meshavand: molekulaho bo payvastagii karbon-gidrogen, karbon-nitrogen, nitrogen-gidrogen va oksigen-gidrogen. Ilova ba in, az garmii jozibai jinshoi Zamin ehtimol gidrogen, metan, oksidi karbon, ammiak, ob va gayraho niz paydo shudaand.
Dar haqiqat, dar atmosferai avvalini Zamin kadom hodisaho ba amal meomad? Baroi muayyan kardani in boyad donist, ki kadom namudhoi energiya ba atmosferai Zamin beshtar tasir rasonidaand.
