Ulwazi mayelana ilanga. Amaqiniso ethakazelisayo Welanga

Bright kwelanga - umthombo ajabule futhi ukahle kakhulu. Ngo sezulu liguqubele abantu abaningi bagajwa, isivuno ecindezelekile. Naphezu kwakho konke lokhu, wonke umuntu uyazi ukuthi maduze isiphepho kuzophela, futhi kubonakala sengathi ilanga esibhakabhakeni. Kuyinto ejwayelekile ukuthi abantu kusukela ngiyingane, futhi bambalwa abantu abacabanga ukuthi inkanyezi. Ulwazi eyaziwa kakhulu mayelana Sun - wukuthi liyinkanyezi. Nokho, zikhona namanje eziningi amaqiniso athakazelisayo ezingase kube nentshisekelo izingane kanye nabantu abadala.

Uyini Sun?

Manje sonke siyazi ukuthi ilanga - inkanyezi, kodwa hhayi elikhulu ibhola elikhazimulayo, okusikhumbuza iplanethi. Kuyinto ifu igesi ne ekhona ngaphakathi ikhenela. Isakhi esiyinhloko le nkanyezi - hydrogen, okuyinto oluthatha mayelana 92% wabantu umthamo yayo. Cishe 7% kuyinto helium, namaphesenti esisele lihlukaniswe phakathi nezinye izakhi. Lezi zihlanganisa yensimbi, umoya-mpilo, nickel, i-silicon, isibabule, nabanye.

Iningi amandla elakhiwe njengoba Fusion inkanyezi yi ane-helium hydrogen. Ulwazi mayelana Sun, ososayensi eqoqwe, singasho sithi G2V yayo uhlobo ngezigaba Spectral. Lolu hlobo ibizwa ngokuthi "yemifino ophuzi". Kulokhu, ilanga, ngokuphambene nenkolelo evamile, shining ukukhanya okumhlophe. kukhanya Yellow kuwumphumela ohlakazayo; ukumuncwa emkhathini iplanethi yethu emfushane-wavelength ukukhanya kwayo. Inkanyezi yethu - ilanga - iyingxenye emthaleni i-Milky Way. Kusukela inkanyezi APC kuyinto at ibanga iminyaka ukukhanya 26.000, futhi omunye revolution kuthatha 225-250 kuphela ngemva kweminyaka eyisigidi.

emisebeni yelanga

Sun Nomhlaba zihlukaniswe ibanga 149.600 th. Km. Naphezu kwakho konke lokhu, emisebeni yelanga liwumthombo oyinhloko wamandla emhlabeni. hhayi wawuqeda wonke lo mqulu sidlula emkhathini. Solar izitshalo amandla asetshenziswa izinqubo-photosynthesis. Ngale ndlela kumiswa compounds ahlukahlukene organic nomoya-mpilo ikhishwe. emisebeni yelanga liyasetshenziswa ekuphehleni ugesi. Ngisho zigcine zamandla Peat namanye amaminerali uvele endulo bedle imisebe inkanyezi ekhanya kakhulu. ngokukhethekile kufanele kube emisebeni ultraviolet ukusuka elangeni. It has izakhiwo isinqandakuvunda, kungasetshenziswa zokukhipha igciwane amanzi. Kuthinta emisebeni ultraviolet ku izinqubo yezinto eziphilayo emzimbeni womuntu, okubangela ukubukeka yilanga esikhumbeni, kanye ukukhiqizwa kavithamini D.

Sun sokuphila

Inkanyezi yethu - The Sun - liyinkanyezi abasha, okuqondene kubantwana kuso isizukulwane sesithathu. Iqukethe semali metal, okubonisa kumiswa kwezinye izinkanyezi izizukulwane zayo zangaphambili. Ngokusho ososayensi, iLanga has iminyaka engaba yizigidi eziyizinkulungwane 4,57. Sikhishwe yokuthi ngibone umjikelezo wokuphila kwe izinkanyezi kuyinto engu-10 bhiliyoni, manje-ke ophakathi. Kulesi sigaba e umnyombo kwelanga kwenzeka Fusion ane-helium hydrogen. Kancane kancane inani hydrogen zingancishiswa, inkanyezi iyoba ibavuthela, futhi likhanya ngendlela efanayo - ephakeme. Khona-hydrogen reserves nengaphakathi ukuqeda ngokuphelele, ingxenye yayo engena udonga lwangaphandle ilanga, ne-helium iqala uphenduke. Izinqubo lantambama izinkanyezi izothatha izigidigidi zeminyaka, kodwa lokho kuyoholela ushintsho yayo yokuqala ibe giant ebomvu bese kuthi ukukhanya okuguqukayo.

Sun Nomhlaba

Izinga emisebeni yelanga kuzoncika eziphilayo eplanethini yethu. Ngemva cishe 1 bhiliyoni iminyaka, kuyoba lungaba namandla kangangokuba surface eMhlabeni nendlu yaqala ukufudumala kakhulu futhi babe engafanele izinhlobo eziningi zokuphila, bayosala kuphela ekujuleni kwezilwandle futhi zindawo polar. Lapho sengineminyaka engu-elangeni kuyinto iminyaka engaba yizigidi eziyizinkulungwane 8, izimo emhlabeni kuyoba eduze nalezo ezikhona ku Venus. Amanzi engahlali, konke ahwamuke. Lokhu kuyoholela ekuthuleni ukunyamalala ephelele zezinto ezihlukahlukene eziphila. Njengoba umnyombo Sun uzobe onomfutho futhi yangaphandle igobolondo izithelo zawo, kuzokhuphula ematfuba ukumuncwa izingqimba zomhlaba wethu elingaphandle plasma inkanyezi. Lokhu akusho kwenzeke kuphela uma uma Umhlaba emhlabeni Sun sizophenduka kude kude inguquko ibe orbit ezahlukene.

amandla kazibuthe

Ulwazi mayelana Sun, abacwaningi eqoqwe, kubonisa ukuthi - inkanyezi magnetoactive. Amandla kazibuthe adalwe ke, ishintsha indlela yayo yonke iminyaka engu-11. amandla ayo iyahlukahluka ngokuhamba kwesikhathi. Zonke lezi zinguquko abizwa ngokuthi umsebenzi elanga, okuyinto libhekene nemicimbi ekhethekile ezifana sunspots, umoya Ukuvutha. Tibangela auroras kanye neziphepho kazibuthe omhlaba, okuyinto zibulale ekusebenzeni kwamanye amadivayisi emhlabeni, inhlalakahle yabantu.

ukusitheka kwelanga

Ulwazi mayelana Sun bahlangana okhokho futhi esekhona, iqukethe Ukukhuluma wokusitheka yakhe kusukela endulo. Inani elikhulu kubo nazo zichazwa Ephakathi. ukusitheka kwelanga - umphumela kuvalwe izinkanyezi kusukela Moon ingqapheli Emhlabeni. Kungenzeka ephelele lapho okungenani eyodwa iphuzu le planethi inhlamvu yelanga ifihlekile ngokuphelele, futhi ngokwengxenye. Ngonyaka kukhona ukusitheka kwelanga ngokuvamile amabili kuya kwamahlanu. Iphuzu elithile Zomhlaba zibonakala umehluko isikhathi iminyaka 200-300. Abalandeli cabanga esibhakabhakeni, ilanga ungabona futhi ukusitheka annular. Moon Star evala disc, kodwa ngenxa ezincane usayizi ubukhulu ayikwazi akusibekele ke ngokuphelele. Umphumela obonakalayo "umlilo" indandatho.

Kuyinto kukhunjulwe kuwufanele ukuthi bagcine Sun ngeso lenyama, ikakhulukazi nezibonakude noma isibonakude, kuyingozi kakhulu. Lokhu kungaholela unomphela ongaboni. Kunendawo eqondile ilanga kolwesiNgisi ebusweni iplanethi yethu futhi likhanya bhá kakhulu. Ngaphandle engozini impilo amehlo kuso, ungabheka ngesikhathi ukuphuma nokushona kwelanga kuphela. Ezinye izindaba zika-isikhathi udinga ukusebenzisa ukuhwalala isihlungi ekhethekile noma afakwa kwi-screen image ezimhlophe etholwe ngosizo isibonakude. Le ndlela ezifanele kakhulu.
