Isakhiwo sonozungezilanga

Ososayensi bakholelwa ukuthi ukwakheka sonozungezilanga waqala yizigidi eziyizinkulungwane ezinhlanu edlule. Ngokwe-standard inkolelo-mbono yokuziphendukela ekhona Zomhlaba namaplanethi elizungezile kwamiswa eduze uthuli kwelanga cosmic. Ngokwe nekucabangela zothuli awabhalwanga nickel nensimbi athomu, kanye silicates. Bakhandwa ngaphansi ukufingqa nothuli samanje eduze amagesi akha carbonaceous kwakwakhe organic. Kamuva, kwakukhona compounds nitrogen hydrocarbon.

Isakhiwo sonozungezilanga: umbono

Akwaziwa hypothesis ka ukuvela isimiso sethu sonozungezilanga kuwumbono kagesi, ogxile nokucabanga ososayensi ngokuthi ilanga owake waba bahla- magnetic field futhi esizungezile esigaxeni yakhiwa ngama-athomu neutrally icala. Ngenxa yalokho, ngemisebe ionization ukushayisana iphutha izinhlayiya okuyinto ogibeni imigca magnetic amandla futhi yathumela emva inkanyezi. Ngemva kweminyaka eminingi iziphathimandla ilanga aqala ukuphelelwa torque wasidlulisela ifu gas, zazo kwamiswa planethi.

Nokho, lo mbono akunakwenzeka. Empeleni, ama-athomu ukukhanya izinto abangu ionized eduze kwelanga, futhi izinsimbi ezisindayo - ku. Futhi umphumela kwakuyoba ukuthi inkanyezi eliseduze iplanethi kwakuzomelwe sakhiwa akhanya izakhi zamakhemikhali - hydrogen ne-helium, futhi akude - nickel nensimbi. Nokho, namuhla singabona isithombe okuphambene.

Ukuze balahle eziphikisanayo, umbono ocatshangelwayo entsha usumisiwe, okubonisa ukuthi ilanga seliya yakha e ekujuleni esigaxeni. Of ligijima ngokushesha okukhulu, futhi esigaxeni kancane kancane ngaqala futhi flat amaningi kuze sebenzi it jikisa nga disk. Ngemva kwesikhathi esithile, waphindela imzuzele ukushesha kanye Sun - kunalokho, iye yabhuntsha. Ngemva kwalokho, kudiski laqala izinqubo, okuholele ekuqaleni kumiswa sonozungezilanga.

Akwaziwa hypothesis ngemvelaphi amaplanethi kuyinto imfundiso yokuziphendukela ukuvela sonozungezilanga kusukela igesi nothuli amafu abandayo ukuthi azungeza ilanga.

Isakhiwo sonozungezilanga: amaplanethi

Namuhla, kunenkolelo yokuthi System Solar siqukethe Sun futhi izinkanyezi namaplanethi ayisishiyagalombili. Ngokusho ubunjalo bomzimba izinto ezingcwele kungenziwa oluthathwa zibe izinhlobo ezimbili. Elinye iqembu kuhlanganisa Umhlaba namaplanethi okuyinto zifana naye - Mars, Venus, Mercury. Eyesibili kuhlanganisa ezifana amaplanethi amakhulukazi we Solar System, Neptune, Uranus, Saturn, i-Jupiter.

Ukuhlukana amaplanethi eyenziwe izici ezintathu: mass, ukuminyana kanye nosayizi. I kwabantu isilinganiso amaplanethi okuqondene eliwumhlaba, izikhathi eziyisihlanu ezingaphezu kuka isibalo esifanayo amaplanethi amakhulukazi. Isakhiwo sonozungezilanga ibonisa ukuthi eduze kwelanga izinto eliwumhlaba yakhiwa oxides, kanye compounds esindayo samakhemikhali: aluminium, magnesium, insimbi, i-silicon okungezona izinto ezimbiwa phansi. Okuphansi ukuminyana imidondoshiya ngenxa isakhiwo sabo. Ziyakwazi esimweni liquid noma gaseous, futhi abe-hydrogen yenqwaba noma helium.

Nokho, isakhiwo yesimiso sonozungezilanga ebonisa ukuthi iyiphi amaplanethi amakhulukazi ngu mass udlula zonke kuhlanganiswe izinto ezingcwele nakho kukodwa. Zonke imidondoshiya sebalulele umoya onamandla ehlanganisa hydrogen yamangqamuzana, futhi equkethe i-ammonia, i-methane,-helium, namanzi. I izinto ezisele Awekho amaphesenti angaphezu kwelilodwa isisindo sabo. Ukwakheka kwalo amaplanethi amakhulukazi efana nezinye izinkanyezi kwasekuqaleni - ilanga.

hydrogen Atmosphere izophela kusukela gaseous kuya ewuketshezi, ngisho e-okuqinile. Kokucindezela rapidity giant ngenxa Ukujikeleza yabo emhlabeni eksisi.

Amaplanethi amakhulu babe izinyanga eziningi: Jupiter ezingaphezu kuka-60, i-Uranus - 27, Saturn - 62, Neptune - 13, kanye amasongo esemkhathini, ehlanganisa, by ukucabangela, ososayensi kusukela impahla satellites ubhujiswe.

Ukuze amaplanethi amakhulukazi kuyinto into elincane isikhala - Pluto. Wavula ngo-1930 futhi akukaqondwa kahle. Kuze 2006 kukholakala ukuthi isimiso sethu sonozungezilanga has amaplanethi ayisishiyagalolunye, futhi Pluto owokugcina wabo. Ngaleso sikhathi samanje lapho siphakathi iplanethi yemifino.
