Ubukhulu kunye nobunzima kweLanga

Ilanga lihlabe kwaye kusibonisa umhlaba. Ubomi bekuya kuba nzima ngaphandle amandla okukhanya. Oku kusebenza umntu nayo yonke enezityalo yomhlaba, izilwanyana. Sun anika zonke iinkqubo ezenzeka Earth. Earth ifumana ukusuka ilanga kukhanya kuphela kunye nobushushu. Ngomhla ubomi emhlabeni yethu aqukuqela amasuntswana gqolo iphenjelelwa iintlobo ntlobo radiation elanga.

Ukwazi ilanga luchaphazela kakhulu impilo yabantu. izaqhwithi Magnetic kubantu abaninzi ukuba ukonakala kweendlela zempilo.

Eli nqaku liza kuxubusha iziseko kwelanga, oko kukuthi, ukwakheka, ubushushu, kwaye inobunzima iLanga, impembelelo eMhlabeni, njl

ulwazi jikelele

Sun - inkwenkwezi ikufutshane kuthi. izifundo Sun zinika ingcaciso malunga iimeko esisabela kwenzeka nezibilini zayo, naphezu komhlaba, ukuvumela ukuba siqonde uhlobo ebonakalayo imizimba obalaseleyo, apho sibona njengendawo ezidanyazayo dimensionless. Isifundo yeenkqubo ezenzeka kule ndawo kwaye kumphezulu kwelanga, kuyanceda ukuqonda iimpawu izenzakalo isithuba kufuphi-Earth.

Ilanga - iziko kwinkqubo yethu iplanethi yethu, nayo leyo equka izijikelezi-8, kwabuzwa Hewana langa, amawaka izijikelezi-langa ezincinane, emkhathini, ezinomsila, igesi omncane, uthuli. Kwinkqubo solar ubunzima iLanga ibamba 99,866% yabo ubunzima iyonke. NgokoMthetho ngeenkwenkwezi umgama ukusuka iLanga ukuya Umhlaba incinane; Ukukhanya kusondele, imizuzu nje 8.

ubukhulu Sun kufuna ingqalelo ekhethekileyo. Le enkulu, hayi kuphela ubungakanani kodwa ngokwemiqathango nkwenkwezi. ububanzi balo idlula sangqa uMhlaba amaxesha 109 lo mqulu, ke, -. Ukuze 1.3 yezigidi amaxesha.

Iqondo lobushushu omalunga lwe Sun - 5800 degrees, ngoko phantse ibengezela ukukhanya emhlophe, kodwa ngenxa ukufakwa esomeleleyo ukusasazeka indawo elifutshane zomhlaba umoya ngqo ukukhanya spectrum yelanga kufutshane kumphezulu planethi ufumana mthubi.

Lobushushu kwindawo engundoqo ye ilanga efikelela 15 Mill. Amaqondo. Ngenxa lobushushu eliphezulu into elanga sikwimo sukube kwaye ngaphakathi athom inkwenkwezi nyama- imichiza zahlulwe elektroni ezamahala-asli nuclei atomic.

Ubunzima of the Sun - 1.989 * 10 ^ 30 kg. Eli nani mkhulu ubunzima komhlaba lamawaka 333. Times. Ukuxinana avareji ukwimo ilingana no 1.4 g / cm3. I-avareji density Umhlaba ngaphezu phantse esibayeni-4. Ukongeza, kukho ingqiqo ngeenkwenkwezi ubunzima kwelanga - iyunithi yokulinganisa ubunzima, nesetyenziswa ukuvakalisa ubunzima iinkwenkwezi nezinye izinto ngeenkwenkwezi (ehla-).

Ubunzima sukube elanga sigcinwa ithandwa eqhelekileyo kweli ziko. Umphantsi nomphezulu sobunzima kwabo zixinaniswe enzulu, kanye nokwanda nobunzulu umaleko xi inyuswe.

Xi embindini ilanga ifikelela umoya ezimakhulu billion, nangona kunjalo into ezinzulwini elanga ezixineneyo.

Oku kukhokelela ukuvuza of reactions fusion kwigumbi langaphakathi kwelanga, ngenxa hydrogen ibe helium kwaye likhupha amandla enyukliya. Ngokuthe ngcembe lo amandla "ezivuzayo" ngokusebenzisa into ngaphaya elanga, okokuqala kwiingcamba engaphandle, yaye emva koko obubonakala okukuwo.

Ukubunjwa ilanga kuquka izinto ezifana hydrogen (73%), helium (25%) kunye nezinye izinto enamandla asezantsi kakhulu (nickel, initrogen, isalfure, ikharbon, calcium, intsimbi, ioksijini, lesilicon, nemagnesium, neon, Konqueror).
