Ngokuqinisekileyo sonke sibonile a Umnyama ngokupheleleyo welanga okanye inxalenye. Ezi ziganeko ngokuqhelekileyo zenzeka okwethutyana ngenxa yokujikeleza komhlaba, ukuhamba koguqulo kunye nokuma ngokubhekiselele kwinyanga kunye nelanga.
Kweli nqaku siza kukuxelela yonke into ofuna ukuyazi malunga nokusithwa kwelanga yilanga, oko kufuneka kwenzeke kunye nendlela onokuyibona ngayo.
Yintoni umnyama ngokupheleleyo welanga
Ukusithwa kwelanga yinyanga sisiganeko apho iNyanga ibekwe phakathi kweLanga kunye noMhlaba kwaye inokurhoxisa ngokupheleleyo, ngokuyinxenye okanye iyitshitshise, kuxhomekeke kubungakanani, indawo kunye nomgama phakathi kweenkwenkwezi.
Kwi-avareji, ukufiphala kwelanga kwenzeka rhoqo kwiinyanga ezili-18 kwaye kuthatha imizuzu embalwa kuphela. Ukusithwa kwelanga yinyanga okufanayo kwakuza kuthabatha iminyaka engama-400 ukuze kuphindeke kwindawo enye eMhlabeni. Oku kubangelwa kukuba, kanye njengokuba umhlaba ujikeleza ilanga, nenyanga nayo ijikeleza kumjikelezo wayo oyi-elliptical, kodwa ijikeleza isijikelezi-langa sethu.
Xa umgca wengqikelelo utsalwa ochaza intshukumo yokuguqulela yomzimba wasezulwini, kunokubonwa ukuba indlela ye-orbit i-elliptical. Ngoko ke, kuxhomekeke kwindlela, inyanga isondele okanye ikude emhlabeni, kwaye zombini zisondele ngakumbi okanye ngaphantsi kwelanga. Yiyo loo nto bengasoloko befola ngendlela efanayo okanye ngexesha elinye lonyaka.
Kutheni kusenzeka umnyama welanga?
Intshukumo yokuguqulela yoMhlaba kunye nesathelayithi yawo yendalo ithetha utshintsho kubukhulu besithunzi esifakwe yiNyanga eMhlabeni ngexesha lokusithwa kwelanga yinyanga. Okukhona inyanga isondele eMhlabeni, kokukhona isithunzi sayo somelele kwaye sincinci ububanzi bayo. Ngoko, kukho ukukhafula kwelanga; oko kukuthi, ukufiphala ngokupheleleyo kwelanga kubonakala kuphela kummandla apho isithunzi sifakwe khona. Ukusuka kweminye imimandla ekufutshane efikeleleka kuphela yipenumbra yenyanga, into efanayo ithathwa njengomnyama welanga.
Ukuvavanya le nto ngendlela elula, ibhola inokufakwa phakathi kwesibane kunye nodonga. Ngokusondeza ibhola ekukhanyeni, isithunzi esibeka eludongeni sikhulu kwaye sithambile. Ukuhambisa ibhola kufutshane nodonga kwenza ububanzi besithunzi bube buncinci kwaye buqine ngakumbi.
Ukuba ibhola yinyanga, iindonga ziiplanethi kwaye ukukhanya lilanga, iimeko ezahlukeneyo zokusithwa kwelanga yilanga zinokulinganiswa ngokuhambisa ibhola.
iintlobo zokusithwa kwelanga yinyanga
- umnyama ngokupheleleyo welanga Inokubonwa kuphela kwindawo ethile yoMhlaba, embindini wesithunzi esifakwe yiNyanga eMhlabeni. Ukusuka apho, kunokubonwa ukugcwala kweenkwenkwezi ezikhanyayo.
- ukusithwa kwelanga yinyanga. ILanga liye lafumana i-occultation inxalenye, enokuthi ibonwe kwindawo yomthunzi woMhlaba owenziwe ngumthunzi weNyanga. Ungayibona inkwenkwezi eqaqambileyo ifihlwe ngokuyinxenye ngelixa uncoma ukuqaqamba kwayo okumilise okweceba.
- umnyama wonyaka. Ngokungafaniyo nenxalenye yokusithwa kwelanga yinyanga, inyanga ayiliphosi isithunzi esilifihla ngokupheleleyo ilanga ngenxa yomgama ophakathi kwenyanga noMhlaba, kodwa endaweni yoko ityhila ihalo eyijikelezileyo.
Izilumkiso zokujonga ukusithwa kwelanga yinyanga ngokupheleleyo
Ukusithwa kwelanga yinyanga akufuneki kubonwe ngokuthe ngqo. Nangona oku kuyinto yendalo, kubalulekile ukuthatha amanyathelo okhuseleko kuba ukujonga ngokuthe ngqo elangeni ixesha elide ngosuku oluqhelekileyo okanye ngexesha lokukhanya kwelanga kunokubangela ukutshisa kwe-retinal kunye nokungaboni ngokusisigxina. Imitha eyikhuphayo yomelele kangangokuba inokonakalisa umbono ixesha elifutshane kakhulungakumbi abancinci.
Kukho iiglasi ezilungiselelwe ngokukhethekileyo ukujonga ukukhanya kwelanga kunye neelensi ezineepropathi ezifana neemaski ze-welding. Nangona ijongwa ngeelensi ezikhethekileyo, ukujonga ngaphezulu kwemizuzwana engama-30 ngexesha akukhuthazwa. Kwezi meko, iiglasi zelanga esizinxiba mihla le azikhuseli.
ukusithwa kwenyanga
Ukusithwa kwelanga yinyanga kwenzeka xa uMhlaba uphakathi kwelanga nenyanga, ukushiya inyanga kubumnyama obupheleleyo okanye obuthile kwaye ingafumani kukhanya kwiinkwenkwezi eziqaqambileyo.
Ukufiphala kwenyanga kubonakala kuzo zonke iindawo zomhlaba apho inyanga ibonakala khona, ngelixa i-solar eclipse ingabonwa kuphela kwindawo eMhlabeni apho inyanga iphosa isithunzi. Ngokungafaniyo nomnyama welanga, othabatha imizuzu nje embalwa, unokuthabatha imizuzu engama-30 ukusa kwiyure enye.
mythos
Ngokunxulumene nembono yomntu, ukusithwa kwelanga yinyanga akukude ngasemva. Xa abantu babengakwazi ukuyichaza le nto, waqalisa ukwenza amabali ngoko kwakunokwenzeka.
Impucuko yamandulo yayikholelwa ukuba yayingoothixo abathumela "imiyalezo" ngeenkwenkwezi. IiVikings zithi ingcuka yaliqwenga ilanga yaza yenza ingxolo “ukuloyikisa”. Umphumo uba kukuba ilanga okanye inyanga ibuyela kwimeko yayo yendalo, ize izomeleze ngakumbi iinkolelo zakho.
Kwandula ke, kwizizukulwana zanamhlanje, iintsomi zavela, ngaphandle kwengcaciso yenzululwazi, kodwa zinobungqina obaneleyo bokuba zazinokwenzeka. Umzekelo:
Indlela yokuziphatha kwezilwanyana ayilawuleki
Asikuko ukuba ukuziphatha kwezilwanyana akulawuleki, lo tshintsho lwequbuliso ukusuka ekukhanyeni ukuya kumnyama, okanye ngokuphambeneyo, obangela ukuba izilwanyana zitshintshe izingqisho zabo ze-circadian ukuze zivumelane noko kwenzekayo kwindawo yazo.
Ebudeni bokusithwa kwelanga yinyanga ngokupheleleyo, sinokubona iintaka zithe ngcu emithini okanye iirakuni zikhangela ukutya. Oku kungenxa yokuba ubumnyama bukuxelela ukuba umsebenzi wakho mawuphele okanye ungaqala.
Usana lwakho lunokuzalwa luneengxaki zempilo
Kuqhelekile ukuba abanye abafazi abakhulelweyo banxibe iiribhoni ezibomvu ukuze bakhusele iintsana zabo ezingekazalwa ekusithekeni kwelanga. Kuthiwa ngaphandle kweteyiphu, iintsana zinokuzalwa zineziphene okanye amabala athile, kodwa kude kube ngoku kwakungekho bungqina besayensi bokuba iqhekeza lelaphu linokugxotha naluphi na uhlobo lwamandla e-cosmic.
unganciphisa umzimba
Yinyaniso, kodwa hayi ngonaphakade. Umxhuzulane unokusivumela ukuba silahlekelwe yi-500 grams, i-700 grams okanye ikhilo, kodwa xa iinkwenkwezi zihamba ngendlela yazo kwakhona, oku kuya kubuyela ngokuqhelekileyo.
Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga nokusithwa kwelanga yinyanga ngokupheleleyo kwaye zeziphi iimpawu zayo.
