Hypothesis ukubunjwa kwehayidrosfere. Njani amanzi on Earth?

Njengoko kwaye xa kukho amanzi on Earth? Izazinzulu nangoku ingxoxo ngalo mbandela, kodwa impendulo ngqo kunye namaxabiso okomqondo sele kanjalo kude kungabikho namnye asinike. Namhlanje, kukho izinto ezimbalwa indlela esingamanzi zenze kwiplanethi yethu. Phakathi kwazo kukho hypothesis ehlekisayo ngokupheleleyo kwaye kakhulu ubhalo, kodwa ukuza kuthi ga ngoku akukho nanye kuzo olungachanekanga ngokupheleleyo.

Njani amanzi on Earth? Isishwankathelo le yeengcinga eziphambili

Amanzi ludlala indima ebalulekileyo ekugcineni ukuphila emhlabeni, t. To. Yeyona bume ephambili yangaphakathi nayiphi ephilayo. Ngaphandle amanzi umntu angaphila ukuya kwiintsuku ezintathu avareji, ilahleko 15-20% wamanzi kaninzi ekhokelela ekufeni.

Njani amanzi on Earth? Hypothesis ukuyilwa kwalo iziyobisi mbalwa, yaye akukho namnye kubo ungekabikho ubungqina eyinyaniso. Noko ke, wona kuphela thile ukuchaza lokusekwa kwehayidrosfere komhlaba wethu.

Hypothesis imvelaphi cosmic amanzi

Iqela labaphandi ziye zacebisa ukuba yamanzi yabonakala kunye kuwa awe esibhakabhakeni ezininzi. Oku kwenzeka malunga 4.4 billion kwiminyaka eyadlulayo, xa umhlaba lisathukuza layo, yaye ubuso bawo owomileyo, senkangala, emoyeni sele lalingekabunjwa apho.

Kwi lo mbuzo, njani amanzi on Earth, abaxhasi hypothesis banoxanduva ukuba molekyuli yokuqala kulwelo wabangenisa nabo awe esibhakabhakeni. Okokuqala, le iimolekyuli zikhona ngokohlobo igesi kunye ezingasetyenziswanga, yaye kamva, xa umhlaba waqalisa ukupholisa, amanzi ocande urhulumente ulwelo yaye ayila kwehayidrosfere zomhlaba.

Mhlawumbi ukuyilwa eekhemikhali kwamanzi injengayo ukususela protons hydrogen zamabanga anions ioksijini, kodwa amathuba sokungamelani enjalo Ebubanzini imizimba yasezulwini, nayo eyakhupha ziwe emhlabeni abe yintlekele yodwa.

Enye hypothesis, njani amanzi on Earth

Uye wacebisa iqela labaphandi elikhokelwa Scientist owaziwayo VS Safronov. kubume bayo siyifumana Kwingcingane imvelaphi yasemhlabeni emanzini, nto leyo kwasekwa enzulwini planethi.

Phantsi yesenzo awe esibhakabhakeni ezininzi kuwa ngexesha umhlaba wethu uye yale igqengezelayo generate isixa esikhulu iqhuma, leyo owalwa daka. Kunye ukuba kumphezulu wema "umphunga", nto leyo eyabangela ukuba ukuyilwa kwehayidrosfere komhlaba.

Ngaphandle kwento yokuba imfundiso wabeka isiseko imvelaphi yasemhlabeni amanzi, akakwazi ukuphendula imibuzo emininzi. Umzekelo, indlela iliwa lithosfere ukuba kangaka Inyibilikile ukuba kungakhokelela ekubunjweni mlilo ezininzi? Nendlela umphunga wamanzi kwakhiwa? Ekuqaleni, izazinzulu ziye kucingelwa ukuba ngelo xesha kwakukho Wawucolwa amanzi, ndinobo mlilo kunye daka kuqhume ukwimeko sukube.

Le ngcamango ka ukuyilwa zomphunga wakhanyela P.Perro, ngenkulungwane semvelo 17. Ungqinile ukuba omhlaba kuyilwa ngenxa imvula, yaye oku kufuna ukuba kukho umoya. kwiminyaka 4.4 billion eyadlulayo, akakho emoyeni.

Imfundiso yokugqibela

Ngoko njani amanzi on Earth? Enye ingcamango bakwazi ukuza kwelinye icala ukuya umbuzo ekubunjweni kwehayidrosfere le planethi. Njengoko kuze kuqaliswe edlulileyo VS Safronov bakhe co-ababhali, le hypothesis nto bakucaphukele ngamanzi imvelaphi eziphila.

Umahluko kukuba ngokutsho abaphandi, ezo molekyuli amanzi akhekha disk protoplanetary komhlaba, oko kukuthi, ngexesha lokusekwa langa ngokwaso. Lo mthombo iimolekyuli zamanzi wakhonza deuterium neoksijini.

Deuterium i hydrogen aqhelekileyo kunye neutron enye yaseburhulumenteni. Le Isotope enzima kwafunyanwa iisampulu yamandulo abangelwe afumaneka kwi-Arctic kwi Baffin Island (1985). Ezi namawa akhiwa amasuntswana of protoplanetary uthuli ayengaseleki ngexesha lokusekwa planethi. Ngokutsho kwabaphandi, uhlobo eekhemikhali deuterium ukuba avumele Isotope usenziwa iplanethi.

Oku yindlela kwakukho amanzi ehlabathini ngokwezo izazinzulu. Ukuba ezi data zichanekile, ukuyilwa le disk protoplanetary kwabunjwa malunga nama-20% kwiilwandle zehlabathi zanamhlanje. Namhlanje, abaphandi ukhangela indlela ukungqina ukuba kumanzi "protoplanetary" Bakha uninzi elwandle, ngokunjalo umphunga wamanzi uwabonisa omhlaba.
