Hypothesis ukwakheka hydrosphere. Kwenzeka kanjani ukuba la amanzi emhlabeni?

Njengoba futhi lapho kuba khona amanzi emhlabeni? Ososayensi namanje siphikisana ngale ndaba, kodwa impendulo eqondile nenengqondo okuye kwabonakala kuze kube manje akekho anginike. Namuhla, kukhona iziphakamiso ezimbalwa zendlela ketshezi ungakheka emhlabeni. Phakathi kwabo kukhona umbono okungenangqondo ngokuphelele futhi ngempela okunengqondo, kodwa kuze kube manje akekho kubo akuyona olunembile ngokuphelele.

Kwenzeka kanjani ukuba la amanzi emhlabeni? Isifingqo imicabango esemqoka

Amanzi linendima ebalulekile ekulondolozeni ukuphila emhlabeni, t. Ukuze. Kuyinto main imvelo yangaphakathi kwanoma iyiphi umzimba. Ngaphandle kwamanzi umuntu angaphila izinsuku ezintathu ngokwesilinganiso, kutholakala into ukulahlekelwa 15-20% amanzi kaningi esiholela ekufeni.

Kwenzeka kanjani ukuba la amanzi emhlabeni? Hypothesis kumiswa yalolu ketshezi zimbalwa, futhi akekho kubo oye azikakwazi ubufakazi eyiqiniso. Nokho, kuphela bakwazi ukuthi ngandlela-thile wakuchaza kanjani ukwakheka le hydrosphere kule planethi yethu.

Umbono Lokudabuka cosmic yamanzi

Iqembu abacwaningi baye bacabanga ukuthi amanzi abonakala emkhathini eziningi iwe. Lokhu kwenzeka eminyakeni engaba yizigidi eziyizinkulungwane 4.4 edlule, lapho planethi isencane isakhasa, futhi ubuso bayo esomile, izwe libe yincithakalo, phezu okuyinto emkhathini ingakamiswa kwakhiwa.

On umbuzo, kanjani amanzi emhlabeni, Abasekeli lo mbono banesibopho ukuthi amangqamuzana lokuqala lalolu ketshezi ayenokuhlangenwe emkhathini. Okokuqala, la mangqamuzana khona ngesimo igesi futhi zanqwabelana, futhi kamuva, lapho iplanethi waqala kuphole, amanzi sidlulile sesimweni ketshezi futhi kwakhiwa hydrosphere zomhlaba.

Mhlawumbe ukwakheka kwamakhemikhali emanzini livelile hydrogen eyinhloko proton ne-oksijini anions, kodwa ematfuba ukusabela ngaleyo ndlela kuleli ukujiya kwezindikimba zasezulwini, lapho kamuva awele phansi a inhlekelele encane.

Omunye umbono, kanjani amanzi Emhlabeni

Wasikisela iqembu labacwaningi eliholwa usosayensi odumile VS Safronov. essence yayo itholakala nokucabanga umsuka esemhlabeni amanzi, okuyinto kwamiswa ekujuleni iplanethi.

Ngaphansi isenzo wazo eziningi iwe ngesikhathi iplanethi yethu isibe esikhipha ukukhiqiza semali kuqhume intabamlilo, zazo balwisana magma. Ndawonye nalo kwamanzi wema "umusi", okwabangela kumiswa hydrosphere emhlabeni.

Naphezu kweqiniso lokuthi imfundiso yokuziphendukela wabeka isisekelo umsuka yasemhlabeni amanzi, Awukwazi ukuphendula imibuzo eminingi. Ngokwesibonelo, indlela amadwala lithosphere is kangaka elicibilikile buholele kumiswa-mlilo eziningi? Futhi indlela Umhwamuko uhamba kwakhiwa? Ekuqaleni, ososayensi baye baveza nokuthi ngaleso sikhathi kukhona kwakugaywa amanzi, okuyinto ngokusebenzisa mlilo ne magma kuqhume esimweni gaseous.

Lo mbono kwetinhlavu umusi inqatshelwe P.Perro, isazi semvelo ngekhulu le-17. Akabanga ukuthi komhlaba kwakhiwa ngenxa kwezulu, futhi lokhu kudinga khona isimo. eminyakeni 4.4 billion edlule, umkhathi wayengekho.

Imfundiso lokugcina

Ngakho kanjani amanzi emhlabeni? Omunye umbono singafika ngaphesheya yombuzo ukwakheka hydrosphere planethi. Njenganoma nokucabanga VS esidlule Safronov nokubambisana abalobi yakhe, lo mbono is wacasulwa amanzi Lokudabuka eliwumhlaba.

Umehluko ukuthi ngokuvumelana abacwaningi, amangqamuzana amanzi kwamiswa disk protoplanetary Zomhlaba, okungukuthi, ngesikhathi kumiswa iplanethi uqobo. Umthombo amangqamuzana awuketshezi wakhonza njengephayona deuterium nomoya-mpilo.

Deuterium kuyinto hydrogen ezivamile nomunye neutron e-nucleus yayo. Lokhu IKhompyuthaYami esindayo itholwe basalt yasendulo amasampula atholakala Arctic ku Baffin Isiqhingi (1985). Lezi amadwala akhiwa izinhlayiya ngothuli protoplanetary bangaveziwe ngesikhathi kumiswa emhlabeni. Ngokwe-abacwaningi, ubunjalo amakhemikhali deuterium ngeke uvumele kumiswa IKhompyuthaYami is iplanethi.

Nansi indlela amanzi wabonakala ku-Earth ngokuvumelana nalezi ososayensi. Uma lezi idatha ziyiqiniso, kumiswa kudiski protoplanetary kwamiswa mayelana 20% izilwandle zomhlaba yesimanje sika. Namuhla, abacwaningi ufuna ithuba lokubonisa ukuthi kusukela "protoplanetary" amanzi akhiwa iningi izilwandle zomhlaba, kanye asemkhathini umhwamuko kanye komhlaba.
