Usayizi nesisindo weLanga

Ilanga lifudumeza futhi likhanyisa iplanethi. Ukuphila kwakuyoba awunakuba khona ngaphandle kokuthethelela amandla okukhanya. Lokhu kusebenza futhi umuntu futhi wonke izitshalo ezisemhlabeni, nezilwane. Sun anika zonke izinqubo ezenzeka Emhlabeni. Umhlaba uthola kusukela ilanga akuyona kuphela ukukhanya nokushisa. On the ukuphila kule planethi yethu ageleza izinhlayiya ngokuqhubekayo kuthonywa Tinhlobo emisebeni yelanga.

Ukuchayeka ilanga kuthinta kakhulu empilweni yomuntu. Iziphepho Magnetic kubantu abaningi kubangele Ukuwohloka impilo.

Lesi sihloko sizodingida izinto eziyisisekelo ilanga, okungukuthi, ukwakheka, izinga lokushisa, futhi mass of the Sun, umthelela eMhlabeni, njll

ulwazi olujwayelekile

Sun - inkanyezi abaseduze nathi. Sun izifundo kuhlinzeke imininingwane ngokufinyelela kwi izimo ukusabela ezenzeka elingaphakathi yayo futhi phezu kobuso, esisiza ukuba siqonde isimo ngokomzimba zemizimba lezinkanyezi, okuyinto sibona njengoba dimensionless iphuzu Siyafulesha. Ucwaningo we izinqubo ezenzeka kuleyo ndawo futhi phezu kobuso ilanga, kusiza ukuqonda isici izenzakalo isikhala eduze-Earth.

Ilanga - maphakathi uhlelo amaplanethi, okuyinto sihlanganisa amaplanethi 8, eziningi iziphuphutheki kwamaplanethi, izinkulungwane asteroyidi, emkhathini, lezinkanyezi ezinomsila, igesi interplanetary, uthuli. Zesimiso sonozungezilanga mass kwelanga liphetheni 99,866% we isisindo ingqikithi. Ngamagama yezinkanyezi ibanga eLangeni uMhlaba incane: ukukhanya imizuzu 8 nje.

usayizi Sun idinga ukunakekelwa okukhethekile. Lena omkhulu, hhayi kuphela ubukhulu kodwa futhi ngokuya inkanyezi. Ubukhulu bayo idlula ububanzi we Earth izikhathi 109 ivolumu, esikhundleni salokho, -. Ukuze 1.3 million izikhathi.

I eseduze izinga lokushisa kwe-Sun - 5800 degrees, ngakho cishe likhanya ukukhanya okumhlophe, kodwa ngenxa ukumuncwa eqinile futhi kusakazeka endaweni esifushane wonke umoya oqondile spectrum solar ukukhanya eduze kobuso iplanethi uthola ophuzi.

Amazinga e-zone-central kwelanga ifinyelela 15 Mill. Degrees. Ngenxa izinga lokushisa kuqhathaniswa okusezingeni eliphezulu izidakamizwa solar isebujameni gaseous namaphakathi nezwe isidlakela inkanyezi athomu ezakhi chemical zihlukaniswe electron khulula ezinyakaza kanye nuclei athomu.

IMisa weLanga - 1.989 * 10 ^ 30 kg. Lesi sibalo mkhulu mass Zomhlaba e ayizinkulungwane 333. Times. I kwabantu isilinganiso ketshezi ilingana 1.4 g / cm3. Isilinganiso ukuminyana Zomhlaba ngaphezu cishe 4-emhlanjini. Ngaphezu kwalokho, kukhona umqondo kwezokuhlolwa kwezinkanyezi nesayensi nenqwaba kwelanga - iyunithi yokukala isisindo, okuyinto lasetjentiswa kute kuvetwe mass zezinkanyezi nezinye izinto yezinkanyezi (imithala).

I gaseous mass solar oluphethwe bakhangane ezivamile maphakathi. Zogqinsi engenhla isisindo sabo onomfutho ezijulile, kanye nokwanda ungqimba ingcindezi luyanda ukujula.

Ingcindezi emaqaqasini kwelanga kufika izikhathi eziphindwe engamakhulu bhiliyoni Nokho into ekujuleni yelanga has high density.

Lokhu kuholela ukuvuza Fusion ukusabela emaqaqasini ilanga, ngenxa hydrogen ku-helium ne-likhipha amandla enuzi. Kancane kancane le energy "ukuvuza" ngokusebenzisa opaque izidakamizwa welanga, okokuqala kule engxenyeni engaphandle, bese afike akhanye khona emkhathini, esisibona ngamehlo.

Ukwakheka ilanga ifaka izinto njenge-hydrogen (73%), helium (25%) kanye nezinye izakhi lokuhlushwa ephansi kakhulu (-nickel, i-nitrogen, isibabule, carbon, i-calcium, okusansimbi, i-oksijini, i-silicon magnesium, neon,-chrome).
