Pfungwa paumbwe hydrosphere. mvura Pasi sei?

Sezvo uye kana kwaiva mvura Panyika? Masayendisiti vachiri hatifaniri kukakavadzana nezvenyaya iyi, asi chairo uye musoro mhinduro zvave zvakadaro kure hapana apa. Nhasi, pane mazano sei nemvura zvingaite panyika vashoma. Pakati pavo vane zvachose penga uye zvikuru musoro pfungwa, asi zvakadaro kure hakuna hakusi yakarurama zvachose.

mvura Pasi sei? Pfupiso huru hypotheses

Mvura inoita basa rinokosha kuramba upenyu panyika, t. To. Ndiro huru womukati ezvinhu chero muviri. Pasina mvura munhu anogona kurarama kusvika mazuva matatu paavhareji, kurasikirwa 15-20% mvura kazhinji kunotungamirira kurufu.

mvura Pasi sei? Pfungwa inotungamirwa yamarudzi ichi vashoma, uye hapana umwe wavo haasati kunge chokwadi uchapupu. Zvisinei, chete vanogona zvimwe kutsanangura paumbwe hydrosphere yedu.

Pfungwa pamusoro yepasi pose kwakabva mvura

Boka vatsvakurudzi vakafunga mvura yakaonekwa pamwe dzakawanda meteorites kuwa. Izvi zvakaitika anenge mabhiriyoni 4.4 apfuura, apo nyika iri kuchangotanga, uye ayo pamusoro pakaoma, nyika dongo, pamusoro izvo muchadenga asati aumba.

On the mubvunzo, sei vakaita mvura Panyika, vatsigiri pfungwa iyi ndivo basa kuti mamorekuru nemvura wokutanga vakauya navo meteorites. Chokutanga, mamorekuru izvi zviripo muchimiro gasi uye vaunganidza, uye gare gare, apo nyika yakatanga ichitonhorera, mvura wakapfuurira mvura nehurumende uye akaumba hydrosphere enyika.

Zvichida makemikari paumbwe mvura yauya kubva chikuru rehydrogen protons uye neoxygen anions, asi mukana yakadaro nezvinoita pakukora kwemiviri yokudenga, vakazochinja pasi aiparadza duku.

Imwe pfungwa, sei vakaita mvura Panyika

Akaronga boka vaongorori rinotungamirirwa mukurumbira musayendisiti VS Safronov. Chaizvoizvo Its iri nokufungidzira yepasi kwakabva mvura, iyo yakaumbwa muna pakadzika nyika.

Pasi zvinoitwa dzakawanda meteorites kuwira panguva redu rava incandescent vaunze yakawanda kwemakomo, iyo akatambura magma. Pamwe chete kuna pamusoro akamira "chiutsi", izvo zvakakonzera paumbwe pasi hydrosphere.

Pasinei chokwadi kuti dzidziso nheyo yepasi kwakabva mvura, hachigoni kupindura mibvunzo yakawanda. Somuenzaniso, sei matombo lithosphere yanyungudika zvakawanda kuguma paumbwe zhinji anoputika? Uye kuti mvura mhute aumba? Pakutanga, masayendisiti vaifungidzira kuti panguva iyoyo kwakanga zvakohwewa mvura, riri kuburikidza anoputika pamwe magma anongoita nharo vari gaseous ezvinhu.

Pfungwa iyi paumbwe chiutsi akaramba P.Perro, zvakasikwa muzana remakore rechi17. Akaratidza kuti pasi kuumbwa nokuda kwemvura, uye izvi zvinoda pamberi ezvinhu. bhiriyoni 4.4 apfuura, mhepo hariko.

The yokupedzisira dzidziso

Saka sei mvura Panyika? Imwe pfungwa aigona kuuya kubva mhiri kumubvunzo paumbwe hydrosphere panyika. Sezvinoita kare kubvuma VS Safronov vake co-vanyori, pfungwa iri kutyiswa mvura pano mavambo.

Musiyano wacho kuti maererano vaongorori, mvura mamorekuru akaumbwa protoplanetary dhisiki Nyika, kureva, panguva paumbwe nyika pachayo. Tsime remvura mamorekuru akashanda deuterium uye oxygen.

Deuterium chinhu kwakajairika rehydrogen mumwe Nyuturoni paro. Izvi rinorema isotope kuwanikwa yekare basalt ivhu anowanikwa kweArctic musi Baffin Island (1985). matombo aya aumba kubva tudonhwe muguruva protoplanetary haana pachena panguva paumbwe nyika. Maererano nevaongorori, makemikari yezvakaita deuterium haana kubvumira isotope aumbwa nyika.

Hezvino mvura yakaonekwa panyika maererano masayendisiti izvi. Kana mashoko aya kwakarurama, paumbwe protoplanetary dhisiki yakaumbwa anenge 20% mumakungwa ano nyika. Nhasi, vaongorori vari kutsvaka nzira kuratidza kuti kubvira "protoplanetary" mvura vakaumba ruzhinji mumakungwa, uyewo mumhepo mvura mhute uye pasi.
