Naphezu kokuntuleka komoyampilo, iLanga livutha amazinga okushisa ezigidi zamadigri emkhathini omkhulu womkhathi. Leli qiniso elithakazelisayo, elisekelwe ekuqondeni okungokwesayensi, linikeza ukwaziswa okubalulekile ngokusebenza kwezinkanyezi futhi kungase kumangaze abaningi. Abantu abaningi bayazibuza ukuthi kungani ilanga livutha emkhathini nakuba ungekho umoya-mpilo.
Izimo emkhathini
Inkanyezi eseduze nathi, enesibopho sokusekela ukuphila emhlabeni wethu, ikwisikhundla esibaluleke kakhulu. Ngaphandle kwakhe, ubukhona bethu bungaguqulwa ngokuyisisekelo. Ngakho-ke, kuyadingeka ukuthi sijwayelane nale ndalo yasezulwini ukuze sibonge ubuhle bayo futhi siqinisekise ukulondolozwa kwayo.
Esikhaleni esintula umoya-mpilo, iLanga likhipha ukushisa kwalo okushisayo. Isici esivuthayo, esincike ku-oxygen ukuze siphile, siyayazi. Inikeza imfudumalo phakathi nezinyanga zasebusika futhi iba imbangela yokukhathazeka lapho yeqa imingcele yethu emisiwe. Ngokungangabazeki, ukuphila ngokwako bekungenakwenzeka ngaphandle kokuba khona komlilo, kanye nelanga elibalulekile.
Imithetho yashintshwa ngokufika komlilo, wethula isintu ngezinhlobonhlobo zezingxenye ezisize ushintsho olukhulu ebukhoneni bethu. Lokhu kuthuthukiswa kukhiqize iqoqo lezinto ezibalulekile, okungenzeka ukuthi azilutholile ulwazi lwakho kuze kube manje. Kufanele siqaphele ukubaluleka kweLanga futhi silinikeze inani elilifanele ngempela.
Ukuhlobana phakathi komlilo neLanga kunengqondo, njengoba kudingekile ngokuphelele ukusekela ukuphila ngendlela esikuqonda ngayo. Ukuba khona komlilo akunikezi nje ukushisa, kodwa futhi kwenza kube lula ukulungiselela ukudla, isici esibalulekile ekuziphendukeleni komuntu wanamuhla.
Ushintsho emjikelezweni kwenzekile, okuveza inqwaba yezinto eziyinkimbinkimbi ezisinikeza ukuqonda okujulile kokubili kobuntu nobukhulu bomkhathi. Isimo sokuzivikela siyashintsha, siguqule imithetho futhi sinikeze izimo ezidingekayo ukuze impilo iphumelele. Kwakha indawo egcwele umoya-mpilo, ebalulekile ekusekeleni ukuphila.
Umqondo wokubheja entweni edala inselele edidayo, eveza izithombe zesihogo sasezulwini, uba sobala. Ezimweni lapho ukuba khona komoyampilo kunganele ukuze kube lula ukufika kwale nto, kuphakama incazelo enengqondo, ebonisa ukuthi iLanga lisebenza ngokuhlukile kunomlilo ojwayelekile. Ngakho-ke, iLanga alixhomekile emoyeni ukuze liphile.
Kungani ilanga livutha emkhathini nakuba ungekho umoya-mpilo?
Ukushisa okukhulu kweLanga kunwebeka izinkulungwane zamakhilomitha, kugcina izinga lokushisa lizinzile emhlabeni wethu. Ukusebenza kwayo kufana nokokwenkanyezi ejwayelekile, esebenza ngaphansi kwesenzakalo esihlala singaphezu kokuqonda kwethu kwamanje Emhlabeni. Kubalulekile ukuthi siqonde indima yeLanga ukuze siqonde ukubaluleka kwalo. Ukuze siqonde ukuthi iLanga liwakhiqiza kanjani amandla nokuthi kungani livutha ngaphandle komoyampilo, singabheka isihloko sethu esithi isilinganiso solar kanye nomthelela wawo esimisweni sethu sonozungezilanga.
Ngekhono lokukhiqiza ukushisa okukhulu futhi ufinyelele amazinga okushisa aphezulu usebenzisa izinsiza ezincane, amandla enuzi angamandla amakhulu. Phezu kwa ukungcoliswa kwemvelo namandla okusetshenziswa kwezinsiza, amanye amazwe aze akuchaza njengomthombo wamandla aluhlaza. Amandla afanayo akhiqizwa ukuhlanganiswa ku-solar core angafakwa ezitshalweni zethu zamandla, inqobo nje uma kuthathwa ukunakekelwa okufanele futhi kusetshenziswa ubuchwepheshe obufanele.
Njengabantu, sithola ulwazi lokusebenzisa amandla afanayo neLanga eliwakhiphe iminyaka eminingi. Lokhu okutholakele kusinikeza iqoqo lezinto ezibalulekile okufanele sizinake. Manje yisikhathi sokuba siqonde ukusebenza kwangaphakathi kweLanga, elitholakala kalula ebangeni elinembile ukuze sibe khona ngokugcwele. Isici esiphawuleka kakhulu amandla ayo okuvutha ngaphandle kokuba khona komoyampilo, into ebingeke ifinyeleleke eMhlabeni.
Enkabeni yeLanga, lapho amazinga okushisa efinyelela ku-15 million degrees Celsius, Ama-athomu e-Hydrogen adlula inqubo ephawulekayo yokuhlangana kwe-nuclear, ehlanganisa ukudala i-helium. Ukuze siqonde kabanzi ukuthi lokhu kwenzeka kanjani, singabheka isihloko sethu esithi. Ngokuphawulekayo, cishe amathani ayizigidi ezingu-700 e-hydrogen enza lolu shintsho, okuphumela ekukhiqizeni amathani ayizigidi ezingu-695 e-helium.
Ukushintshaniswa kwemisebe
Ukushintshana kwemisebe okwenzeka ngobukhulu besikhala yikho okusivumela ukuba sibone ukushisa okukhishwa yiLanga Nokho, kubalulekile ukuqaphela ukuthi kuyinani elikhulu lamandla elifinyelela kithi futhi singakwazi ukuzwa imiphumela yako naphezu kokuthi ibanga elikhulu. Lesi simo sisinika amandla okuphila ukuphila okunethezekile, ukuzivumelanisa nokuhlukahluka okubangelwa izinkathi zonyaka nezinye izinguquko ezibalulekile.
Empeleni, sibhekene noshintsho olushintshayo olunamandla okukhiqiza imiphumela engalindelekile uma sizama ukululawula. Ukukhiqiza kabusha izimo zeLanga, okukhiqiza amandla amakhulu, kuwumsebenzi oyinselele kakhulu. Sebenzisa ngokunenzuzo la mandla, okuyinto igcina umbukwane womlilo esiwubonayo nesiwuzwayo ukude, kungadala izinguquko ezibalulekile nezihlala njalo. Mhlawumbe esikhathini esizayo sizokwembula izimfihlakalo zayo futhi sisebenzise amandla ayo angenamkhawulo ukuze siqhubekisele indawo yonke ngaphezu kwemingcele yayo yamanje. Ukuze ufunde kabanzi mayelana nokuthi ukushintshaniswa kwemisebe kusithinta kanjani isimo sezulu, sincoma ukuthi usivakashele imisebe ebusweni bomhlaba.
Manje sekuyaqondakala ukuthi ukukhanya okukhazimulayo kwezinkanyezi kuwumphumela wenqubo yokuhlangana kwenuzi, lapho ama-athomu alula njenge-hydrogen ehlangana ukuze akhe ama-athomu asindayo, njenge-helium. Lokhu kuhlangana kwama-athomu kukhiqiza inani elingavamile lamandla izinkanyezi eziwakhipha ngokuqhubekayo izigidigidi zeminyaka, futhi kubalulekile ukuqaphela ukuthi lesi senzakalo asixhomekile ekubeni khona komoya-mpilo.
Ezinye zezici zeLanga
Enkabeni yalo mzimba wasezulwini kunesifunda esishisa ngendlela emangalisayo, amazinga okushisa afinyelela ku-15 million degrees Celsius. Amandla kazibuthe ayo anamandla aphindwe kabili kunawomhlaba wethu, anomthelela omkhulu kuwo wonke amaSolar System ngokusebenzisa imisebenzi yawo ehlukahlukene. Njengebhola le-plasma, alinayo indawo eqinile, eyihlukanisa nezinye izinto zasezulwini.
Ngaphandle kokuba khona kwenyanga noma iziphuphutheki zemvelo, le ndikimba yasezulwini izungezwe ingqikithi yamaplanethi angu-8 kanye nenqwaba yezinye izindikimba zasezulwini. Ukuzungezisa kwayo kwenzeka ngokuphambene newashi, okuhlanganisa isikhathi esiyizinsuku ezingama-25 kuya kwezingu-35 ukuze kuqedelwe ukuguqulwa okukodwa.
Naphezu kombala walo omhlophe wangempela, ukubukeka kwelanga kuvame ukubonwa njengokuphuzi noma okusawolintshi ngenxa yokusakazeka kokukhanya kwalo okuluhlaza okwesibhakabhaka emkhathini, okunobude obufushane begagasi. Ukuze siqonde ukwakheka nokwakheka kweLanga, singabonisana Sakheka kanjani isimiso sonozungezilanga. Esikhathini esizayo, ILanga kulindeleke ukuthi likhule lifinyelele cishe izikhathi ezingama-200 endaweni yalo yamanje, limboze amaplanethi afana neMercury neVenus. Ilanga liqukethe izendlalelo ezimbalwa, okuhlanganisa umongo, indawo ekhazimulayo, indawo ye-convective, i-photosphere, i-chromosphere, ne-corona. Ekujuleni kwenhliziyo yalo, ilanga lingenela inqubo yokuhlangana kwe-nuclear, liguqule i-hydrogen ibe i-helium.
