Ubuwazi ukuthi iLanga elibonakala njalo ukushona kwelanga liyinkanyezi? Yebo, nakuba ibonakala inkulu uma iqhathaniswa nezinkanyezi esizibona ebusuku, lokhu kungenxa yokuba seduze kwayo noMhlaba. Ukwazi i isakhiwo selanga, uzokwazi okwengeziwe ngaye.
Ilanga liyinkanyezi enkulu kunazo zonke futhi eseduze neplanethi ehlalwa abantu. Inamandla okukhiqiza amandla futhi iwakhanyise endaweni ezungezile, ngakho-ke iyingxenye futhi iyisikhungo sesimiso sonozungezilanga, uhlelo lweplanethi lapho itholakala khona. ILanga liphakathi nendawo yeSolar System futhi likhulu linomumo oyindilinga. Wonke amanye amaplanethi azungeza kuwo. Lesi sihlabani sesineminyaka engu-4.6 billion sikhanya.
Lifundwa kanjani iLanga?
Ngezibonakude ezahlukene zelanga namasathelayithi, ukwakheka kwelanga kuyaziwa; enye yazo yi-SOHO, okuyi-Solar and Heliospheric Observatory. I-NASA, ngakolunye uhlangothi, ngo-2018, yethula i-Parker probe ukukhomba izici ezithile.
Ososayensi abavela ezifundweni ezifana i-astronomy, kuhlanganise nesayensi yokwakheka komhlaba phakathi kokunye, sekungamakhulu eminyaka bebheka isibhakabhaka futhi behlola izenzakalo zaso ukuze bakhe imibono ngaso. Ngokufika kwenkathi yasemkhathini, lezi zifundo zabona ukukhanya kosuku, zacwenga ukwaziswa ngokusekelwa kwe-nuclear physics.
I-"nebular theory" ithi ifu elikhulu lamangqamuzana libe nokuwa kwamandla adonsela phansi. Lo msebenzi wawuyimvelaphi yokuzalwa kwezinkanyezi eziningi ezaziseduze nokuhlangana nezinye i-supernovae. Lokhu kwakha igagasi lokushaqisa okwaholela ekwakhekeni kweLanga elikhanya namuhla futhi kulinganiselwa ukuthi lizoqhubeka lenza kanjalo eminye iminyaka eyizigidi eziyizinkulungwane ezinhlanu.
Ake sifunde kabanzi mayelana nesakhiwo seLanga
Nazi ezinye izici eziyinhloko zeLanga eziye zabonwa eMhlabeni:
ukuma kwelanga
Imizimba eminingi emkhathini, ebhekwa phansi ngezibonakude, ihlale ibonakala iyindilinga, lokhu kungenxa yamandla adonsela phansi awakhayo futhi awahlanganise ngokwawo. Ilanga liyindilinga yegesi engaphelele, ebanjwe ndawonye amandla adonsela phansi futhi iqhume kancane ibheke enkabazwe.
Izakhi ezakha ilanga
Ngokuhlaziywa kwe-spectral, kwakungenzeka ukuhlonza nokuhlukanisa izakhi ezakha le sphere yegesi eshisayo, ezofana noMhlaba kanye namanye amaplanethi akha isimiso sonozungezilanga. Ngenxa yokuthi zonke zidalwe ngasikhathi sinye, yileso naleso sinamaphesenti ahlukene wezakhi kanye ne izingxenye zelanga Yilezi:
- I-Hydrogen engu-72%.
- 26% Helium
- 2% ezinye izinto
Ukukhanya kwayo kwenzeka ngoba i-hydrogen ishiswa ibe yi-helium, kuleso sikhungo esishisa kakhulu.
Tamaño
Ngenxa yesayensi yezinkanyezi, ubukhulu bezindilinga zasemkhathini bazokwaziwa ngokusungula kusuka eMhlabeni i-«ububanzi be-angular»njenge-½ degree. Inkosi yenkanyezi inkulu eduze kwamaplanethi; Inobubanzi obuphindwe izikhathi eziyi-109 kunoMhlaba.
Ibanga okulo
Ucwaningo ngebanga eliphakathi koMhlaba neLanga lwenziwe nge-"Astronomical Unit" kanti lokhu kukhombise ukuthi ibanga lingamakhilomitha ayizigidi eziyi-150.
Isi-Movimiento
I-solar surface inesikhathi sokujikeleza nokudlula Ukunyakaza komhlaba kulinganiselwa ukuthi kuthatha izinsuku ezingu-25 enkabazwe, kuze kufike ezinsukwini ezingu-36 eduze nezigxobo, futhi ngaphakathi ijikeleza njalo ezinsukwini ezingu-27.
Masa
Ngokusebenzisa ifomula esetshenziswa kusayensi yezinkanyezi, lapho isisindo phakathi kwamaplanethi nemithala siqhathaniswa, kunikeza ososayensi isilinganiso esibavumela ukuthi basho ukuthi ilanga linobunzima obuphindwe izikhathi ezingama-332.946 kunoMhlaba futhi lenza u-99.86% wengqikithi yesisindo somhlaba. uhlelo lomkhathi.
Umsebenzi
Ilanga liba nezinkathi zokuyaluza okukhulu, okwenzeka ngokujikeleza ama- sunspots avela ezindaweni zalo kazibuthe, akhiqize wonke ama-electromagnetic spectrum. Ukuze uthole ukwaziswa okwengeziwe mayelana yokugcina, ungafunda mayelana Izikhala zelanga.
ukuminyana kwelanga
Nge-"Theory of Gravitation" kwakungenzeka ukulinganisa ukuminyana. Nakuba incane kunoMhlaba ngenxa yokuthi inegesi, ukuminyana kwayo okumaphakathi kuzungeze u-1.4 g/cm3, iphakeme kunaleyo yamanzi.
Ukugqama
Lesi sici siyinikeza ubukhulu bayo obukhulu kanye nomsebenzi wemisebe yelanga. Ngehora elilodwa iyakwazi ukukhanyisa emhlabeni lokho ekufunayo ngogesi ngonyaka owodwa: okungukuthi 4 x 10 33 ergs/s noma ngaphezu kuka-10 23 kilowatts.
izinga lokushisa kwelanga
Iyahlukahluka ngokwezendlalelo zayo futhi ngayinye inezinga lokushisa elihlukile, nakuba ingaphezulu liyi-10,000 degrees Fahrenheit, phakathi nendawo yayo ingu-27,000,000 degrees Fahrenheit.
Ukusebenza kwelanga njalo kwenza ama-athomu e-hydrogen asebenze kakhulu ngokuhamba kwenuzi, aguquke abe i-helium futhi akhiphe amandla amaningi. Zonke lezi zici ezibonakalayo zenza kube nokwenzeka ukuba amandla akhishwa yiLanga asetshenziselwe ukukhiqiza ukushisa nogesi.
Kwaqala nini ukufunda iLanga?
Ngo-1869, usosayensi waseMelika u-Jonathan Lane waphikisana okokuqala mayelana nokuhlangana kwegesi kweLanga, mayelana namandla alo adonsela phansi aligcina esibhakabhakeni nokuthi lakhiwe umthombo wamandla omaphakathi.
Ngo-1874 u-J. Norman Lockyer washicilela ucwaningo lwakhe ngelanga, embhalweni omkhulu, kamuva owabizwa ngokuthi "Solar Physics" ngeminikelo yakhe kule ndawo. Ekuqaleni kwekhulu lama-XNUMX, isazi sezinkanyezi esizalwa eSwitzerland uJacob Robert Emden sabhala imodeli yokuqala yetiyetha ngeLanga.
Lo sosayensi waqinisekisa ukuthi inkosi yenkanyezi iwuchungechunge lwezingqimba zegesi ezigxilile, ungqimba ngalunye lunengcindezi eqinile ngokwanele ngaphakathi ukuze imelane nesisindo segesi, ngaleyo ndlela ivumele ukukhangwa kwamandla adonsela phansi.
Izifundo ezivumele i-"Theory of gravitation", zavuma ukuthi zenze izilinganiso zokuminyana kwelanga futhi zaqaphela ukuthi liphakeme kunaleso samanzi. Eminyakeni engaphezu kweyi-100 edlule, ngokuthuthukiswa kwe-spectroscopy, ehlola ubuhlobo bemizimba yenyama ne-electromagnetics, kwakungenzeka ukuthola izinga lokushisa leLanga ekukhanyeni kwalo phezulu. Lokhu kwabambisana ngaleyo ndlela kuvumela ukuba kwenziwe izilinganiso mayelana nokwakheka kwamakhemikhali nokucindezela kwawo.
Ekhulwini lama-20, ngezinsimbi eziqinile nezinemba kakhudlwana zokuqaphela iLanga, izinkolelo-mbono zaphinde zacutshungulwa, kwase kuba nokwenzeka ukuba kufundwe okwengeziwe nangcono ngeLanga nezici zalo, futhi kukhiqizwe amamodeli anemininingwane eminingi nanelisa ngokwengeziwe, ngenxa yokuthuthukiswa kwe-atomic physics kanye nethiyori kagesi kagesi, phakathi kokunye.
Ukubunjwa kweLanga
Ngokwesakhiwo selanga, esichaza ubukhulu balo, ubukhulu, ukuminyana kanye nezinga lokushisa, phakathi kokunye, liphinde linikezwe izici ze-spectral.
Ekuqaleni kwekhulu lama-1910, ngo-XNUMX, u-Ejnar Hertzsprung noHenry Norris Russell baklama umdwebo we-Hertzsprung-Russell, owaziwa ngokuthi umdwebo we-HR, igrafu yezinkanyezi ebonisa ukuhlakazeka okukhona phakathi kwezinkanyezi ngokusho:
- Ubudlelwano phakathi kobukhulu obuphelele
- ukukhanya
- Izigaba zeSpectral
- amazinga okushisa asebenzayo
- Linganisa ukukhanya kwayo ngokuqhathanisa nezinga lokushisa layo
Ngesikhathi esifanayo, babefuna ukwazi futhi badalule ukuthi:
"Indlela izinkanyezi ezihamba ngayo ngokulandelana kwezinguquko eziguqukayo nezinamandla ngokuhamba kwesikhathi".
Igrafu ibonisa indawo ekhonjwe njengokulandelana okuyinhloko. Lapho lezi zinkanyezi zivame ukuhlala khona futhi abacwaningi bazihlonze ngokuma kwazo okubonakalayo ngohlamvu olukhulu. I-G2 yisigaba senkanyezi yeLanga.
Ngenxa yokwakheka kwezakhi zayo, ingenye yezigaba zezinkanyezi ezisetshenziswe kule grafu, ngaleyo ndlela inquma inani lezinkanyezi: I, II kanye no-III. Njengamanje, uhlelo lukaMorgan-Keenan lusetshenziswa kabanzi, ngoba lokhu kufakwa ngekhodi kwezinkanyezi, izinhlamvu nezinombolo zasungulwa ukuze kuhlukanise izinga lokushisa nobukhulu bazo.
Isazi sebhayoloji u-TH Huxley kubikwa ukuthi uthe:
“I-chessboard yizwe; izingcezu ziyizenzakalo zendawo yonke; imithetho yomdlalo yilena esiyibiza ngemithetho yeNdalo. Umdlali ongakolunye uhlangothi ufihliwe. Siyazi ukuthi umdlalo wakho uhlala unobulungiswa futhi unesineke. Kodwa futhi siyazi, ngezindleko zethu, ukuthi akalokothi ashalazele iphutha, noma enze nokuncane ukuvuma ngenxa yokungazi. "
ukuhlukana kwangaphakathi kwelanga
Sekuvele kwaziwa ukuthi ilanga liyinkanyezi enkulu kunazo zonke ku-Solar System nokuthi ukwakheka kwalo akuyona into efanayo. Isakhiwo manje sesichazwe ukuze sazi ilanga linezingqimba ezingaki ngaphakathi. Lokhu isakhiwo ilanga akunakwenzeka ukuba kubhekwe ngokuqondile futhi imibono ecatshangelwayo yenziwe kuphela ngokusekelwe emibonweni, ngokusekelwe ezicini zayo zangaphandle. Ihlukaniswe yaba yizingqimba eziyisi-6, isatshalaliswa ezindaweni ezihlukene kahle, kusukela phakathi neLanga.
Isibindi
Iyinkaba yeLanga, izinga lokushisa layo lilinganiselwa ezigidini ezingu-15 °C futhi ubukhulu balo buyi-1/5 yerediyasi yelanga. Ukusuka lapho, amandla ahanjiswa yilanga akhiqizwa ukuze afeze umsebenzi walo omkhulu wenuzi kanye nezingcindezi ezikhona, eziphendula lesi sikhungo sibe i-fusion reactor. Amandla adonsela phansi asebenza njengesizinzisi kulesi siphehli, lapho ukusabela kwenzeka lapho kukhiqizwa izakhi zamakhemikhali ezihlukahlukene.
Esimweni sayo esiyisisekelo, i-hydrogen nuclei (ama-proton) aguqulwa abe yi-helium nuclei eyizinhlayiya ze-alpha, ezinzile ngaphansi kwezimo ezikhona ngaphakathi kwe-nucleus. Izakhi ezisindayo, njengekhabhoni nomoya-mpilo, zibe sezikhiqizwa. Konke lokhu kusabela kukhulula amandla ahamba phakathi kweLanga aze asakazeke kulo lonke iSolar System, kuhlanganise noMhlaba. Kulinganiselwa ukuthi njalo ngomzuzwana, iLanga liguqula amathani ayizigidi ezi-5 libe amandla ahlanzekile.
Indawo enemisebe
Le ndawo yilapho amandla agxile ku-nucleus azokhipha khona. Lesi samba esikhulu segesi esishisa kakhulu sakhiwe kuso futhi sidinga ukudluliselwa, ukusikhulula futhi sisipholise. Lawo mandla aqoqiwe azohamba emshinini wemisebe abheke ngaphandle. Leso sici siyi-plasma, enezinga lokushisa eliphansi kunaleso nucleus, equkethe isilinganiso sama-kelvin ayizigidi ezingu-5.
Ngenqubo ehamba kancane ethatha cishe inyanga, la mandla asesimweni sama-photon aphuma kuyi-nucleus akwazi ukusondela phezulu. Ucwaningo luthi lokhu kubambezeleka kohambo oluya ezindaweni ezingaphandle, ukuze kube lula, ngezinye izikhathi kuthatha izinkulungwane nezigidi zeminyaka.
Indawo eqondisayo
Ngokubambezela ukufika kwama-photon avela endaweni enemisebe, igesi ifinyelela endaweni eshisa kakhulu futhi lapho, ngezinga lokushisa lalolu ungqimba, lehla ngokushesha lifinyelele kuma-kelvins ayizigidi ezimbili, lifinyelele phezulu, likwazi ukupholisa futhi libuyele phakathi nendawo. ilanga
Kule ngxenye yilapho amandla asetshenziselwa ukujikeleza izinto kanye namagesi afuna ukukhululwa ngokushesha kanye nokupholisa okungenzeka kutholakala, ukuze uqale inqubo futhi, kusukela phansi kwale ndawo kuya ebusweni beLanga.
Lapho amandla efika sekwephuzile, ukuthuthwa kwawo kwenziwa nge-convection, ngokusebenzisa isiphithiphithi samagesi emazingeni okushisa ahlukene. Esebenzisa la mandla, ama-athomu ashisayo akhuphukela ezingqimbeni ezingaphandle zeLanga.
I-Photosphere
Iwugqinsi olubonwa eMhlabeni futhi luncane kakhulu kunelanga, luwugqinsi olulinganiselwa ku-300 km kanye nezinga lokushisa elizodlula ku-5.000 °C. Kuvame ukubizwa ngokuthi "i-sphere of light" ngoba isuka lapho iningi lemisebe efika kithi ivela eLangeni iphuma khona.
Lezi zimo zeLanga esimweni esinegesi, esishisayo nesine-ionized, zenza ubuso balo bungenziwa ngezinto ezibonakalayo.
Yakhiwe ngendaba, ehamba egcwele ama-granules acwebezelayo ahlala esebenza phakathi kwemizuzu emi-5 kuya kweyi-15 kuyilapho ekwazi ukukhipha amandla, ephole futhi ebuyela endaweni yangaphambilini.
I-photosphere iyabonakala kusuka Ubukhulu bomhlaba kubantu, nokho, isibonakude esikhethekile esinezihlungi ezifanele siyadingeka. Kukhona amadivaysi alokhu, abaqalayo kanye nososayensi abakhethekile. Uma ibonwa, i-photosphere ibonakala ishintshashintsha ekuqaleni, bese kuthi kamuva ibonakale njengento ewugqinsi engayivumeli ukuthi ingene.
I-Chromosphere
Le elementi ibonwa njengengxenye engaphandle ye-photosphere, egcwele ukukhanya okubomvu kanye nekhabhoni ekhazimulayo ebekwe ngaphezulu kwayo, iwunqenqema oluncane ngokuphathelene nezinye izingxenye.
Ukwakheka kwalolu ungqimba amagesi ane-ionized abonisa izindawo ezinozibuthe ezinamandla futhi anogqinsi olungaphezu kwamakhilomitha angu-10.000. Amagesi asuka ezendlalelo ezahlukene azonqwabelana kulolu nqenqema ukuze akhululwe ngokuphelele, afinyelele izinga lokushisa eliphakathi kuka-5.000 no-15.000 ºC.
Uma ukusitheka kwelanga kwenzeka, kuyenzeka ukubona le ngxenye yesakhiwo seLanga, igesi ye-chromospheric ayimunyi kahle futhi futhi ayikhiphi kahle, isobala kakhulu kumaza amaningi abonakalayo.
Corona
Lolu ungqimba olubalulekile lwelanga luwuzibuthe lapho amazinga okushisa aphezulu akhiqizwa khona futhi ukuminyana kwawo kuphansi kakhulu.Lo msebenzi udonsa imizimba evela kumthala, njengama-asteroids, ama-meteorite noma eminye ezungeza eduze.
Okufanayo kuyadliwa futhi kuhanjiswe ukuze kuyiswe enkabeni ye-nucleus, ngaleyo ndlela kube ukudla kwazo nokuziphilisa ukuze ziguqule zibe amandla futhi ekugcineni ziphenduke zibe umlotha. Ngokudla njalo elangeni, ikhulula ngempumelelo ukushisa okudingekayo Emhlabeni ukuze uphile.
Kulinganiselwa ukuthi izinga lokushisa lalolu ungqimba liphezulu kakhulu, ngenxa yamandla kazibuthe akhiqizwa yiLanga.Nsuku zonke ekushoneni kwelanga, ibhande lokukhanya okufiphele libonakala eduze ne-ecliptic yalo. Le ndawo ihlanganisa inani elikhulu lothuli olukwazi ukusabalalisa ukukhanya okukhishwa ku-photosphere futhi okubizwa ngokuthi ukukhanya kwe-zodiacal. 
Ku-corona bazophinde babonakale, uma kwenzeka ukusitheka, ukugqama kwelanga, ngokusebenzisa izihibe ezenziwe ngegesi nokubanda kakhulu.
I-Heliosphere
Iwungqimba olufiphalisayo, olwakhiwe ama-ion avela ongqimbeni lomkhathi welanga kanye namandla ayo kazibuthe. Le ndawo yesikhala ifakwe umoya welanga namandla kazibuthe, ifinyelela ekukhanyeni kwayo okudlula ku-orbit ye-Pluto. Inonqenqema lwangaphandle olubizwa ngokuthi i-heliopause.
Ukwakheka
Ama-elementi aziwa ngokwesiko ku-Periodic Table asezingqimbeni ezahlukene zeLanga. Iboniswa ngezansi. ilanga lenziwe ngani, okuhlukanisa ukuthi i-hydrogen ne-helium yizakhi ezitholakala kakhulu.

Uphenyo lokwakheka kwelanga ekhulwini lama-XNUMX, lubonise indlela ingxenye ngayinye eyakhiwe ngayo:
ICorona: insimbi, i-nickel, i-calcium ne-argon zitholwe ngendlela yama-ion. ILanga alisafani, ngokusebenzisa izigidi zeminyaka yokuba khona, lishintsha amaphesenti alo ngokubunjwa, lokhu kuzoqhubeka nokwenza njengoba lisebenzisa ukunikezwa kwe-hydrogen ne-helium.
Ukuthola Umsebenzi Welanga
Uma inkanyezi isebenza, yilanga lelo. Ngaphandle njengabantu, kungabonwa nsuku zonke, ukukhuphuka nokubeka kwayo, kodwa ngaphakathi kunesiphithiphithi esingapheli samandla kusuka enkabeni yayo kuya emisebeni ebonwa nsuku zonke emsebenzini welanga. I-Magnetism idlala indima ebaluleke kakhulu kulo msebenzi. Phakathi kwezigigaba ezinkulu ezenzeka eLangeni yilezi:
ukuvelela kwelanga
Ziqashelwa yizakhiwo zegesi ezihlala emazingeni okushisa aphezulu futhi usayizi wazo uyabeka, zakha emqhele futhi zibizwa ngokuthi ukuvelela, ama-bumps noma ama-filaments. Ziyakwazi ukuhlukaniswa endaweni ebizwa ngokuthi yindandatho yelanga, amandla kazibuthe eLanga ayawashintsha futhi aveze njengezakhiwo ezinde ezihlanganayo.
ukukhishwa kwe-coronal mass
Umsebenzi omkhulu owenzeka ngaphakathi ezingqimbeni zelanga, unendlela yokushiya izinto ngesivinini esikhulu ezikhishwayo.
Lawa ma-ejection, okuba yi-coronal mass, ahlala amahora amaningi kuyilapho imigqa yamagnetic field isekhona. Lapho lezi zishabalala, ziyancibilika futhi zixhumane namandla kazibuthe omhlaba futhi yilapho abantu bekwazi ukubona ngeso lengqondo izibuko zasezulwini njenge-aurora borealis ne-aurora australis, ezenzeka eduze nezigxobo zomhlaba.
Izikhala zelanga
Lawa machashazi atholakala ku-photosphere; ayizifunda ezivela ngaphezu kwediski yelanga njengamachashaza amnyama futhi izinga lokushisa lawo liphansi ngokuqina. Zivela njalo eminyakeni eyi-11. Ukuze uthole ulwazi olwengeziwe, ungathintana mayelana .
Ngosizo lwezibonakude zasemkhathini, ososayensi baye bakwazi ukubikezela inani lezindawo ezingaphumeleli kancane emjikelezweni ngamunye. Lawa mabala asebenzayo aqondiswa ukuzungeza kweLanga futhi akhonjiswa phambili nendawo enkulu ehambayo nenye evala iqembu.
Amalangabi
Ilanga ngamandla angaphakathi nangaphandle eliwakhiqizayo, omunye wemisebenzi yalo eyinhloko ukukhipha izinto ku-chromosphere kanye ne-corona. Ngezibonakude zasemkhathini neziphuphutheki, kuye kwaba nokwenzeka ukuthwebula le mibane ezumayo nenkulu kakhulu, ephuma ebusweni belanga, eyaziwa ngokuthi ama-flare.
Ukufa
Esinye sezici zezinkanyezi ukuthi ziyafa. Ilanga lisenesikhathi eside likhona. Lawo mafutha enuzi izingxenye zawo ezinawo awunikeza izigidi eziningi zeminyaka okwamanje. I-Galactically, ngokusho kwezazi zezinkanyezi, iLanga lizoqhubeka lisinika amandla alo angenakuvinjelwa.
Lapho ifa futhi izakhi zayo seziphelile, ukuphila eMhlabeni nakho kuzophela. Ngokungazelelwe ngeke kwenzeke, ososayensi baqinisekisa ukuthi indlela yokufa ingaba, ukuthi iLanga liqala ukukhula futhi libe umzimba omkhulu nobomvu, lesi senzo sizokwenza ukuhwamuka kwemvelo. Izilwandle nezilwandle emhlabeni.
Okuwukuphela kwendlela yokubona lokhu kufa, okulinganiselwa ukuthi kuzokwenzeka eminyakeni engaba yizigidi eziyizinkulungwane ezinhlanu, ukuthi abantu kufanele sebezinze kwenye iplanethi.
La isakhiwo ilanga kusukela ku-nucleus yayo yayiyosakazeka, ngegagasi elibhubhisayo, iqede uMhlaba futhi ikhiqize ngaleyo gesi ekhanya kakhulu, i-nebula enkulu. Ngaphakathi kwalo, izinsalela zelanga elidala zaziyohlala, zibe "i-white dwarf" encane kakhulu, futhi izinsalela zelanga elidala zaziyohlala ngaphakathi, ezincane ngobukhulu kunoMhlaba, kodwa ziminyene kakhulu.
Cishe kweminye iminyaka eyi-1000 bhiliyoni, lizophola kancane kakhulu, okungenzeka lithathe izinkulungwane ezimbalwa zeminyaka ukuba libe mnyama. Okwamanje, kuwufanele ukuqhubeka nokufunda isakhiwo sonozungezilanga futhi uyeke ukukhathazeka ngokuwa kwalo, njengoba iLanga selikhona isikhathi esingaphezu kwesigamu sokuphila kwalo futhi lihlala isikhathi eside phambi kwalo njengenkanyezi Yomhlaba, iminyaka engaphezu kwezigidi eziyizinkulungwane ezingu-7000, ngaphambi kokuba ukwehla kwalo kuqale.
