Ngokuqinisekileyo amaxesha amaninzi ubufuna ukuziqhelanisa kwaye ukhangele apho ilanga liphuma khona. Oko wawungumntwana uhlala uxelelwa ukuba iLanga liyaphuma empuma lize litshone entshona. Kananjalo, bekusoloko kukho imiqondiso ethile kwiimovie zasentshona. Ukutshona kwelanga okuqhelekileyo kweorenji kunye nelanga elikhulu eliwela umgca ophelileyo luphawu lokutshona kwelanga, nangona kunjalo, ukuphuma nokutshona kwelanga kuyahluka kakhulu kuxhomekeke kwindawo okhoyo. Ilanga liphuma phi ngokwenene?
Kule posi siza kukuxelela yonke into odinga ukuyazi malunga nayo kwaye uya kuba nakho ukuzifundisa ukuzibeka ngcono ngakumbi ngokukukhokela kweyona nkwenkwezi yethu inkulu. Ngaba uyafuna ukwazi ngakumbi ngalo mbandela? Funda ukuze ufumane yonke into.
Ilanga kwimpucuko yakudala
Inkwenkwezi yethu enkulu ISistema Solar ilungisiwe kwi-Universe. Nangona kunjalo, ngokwembono yomhlaba, nguye obonakala ngathi uyahamba ukusukela, imini yonke, iyatshintsha indawo yayo. Ukuhamba kwento kwenzeka ngokubhekisele kumbukeli. Ngesi sizathu, ukusukela kwimpucuko yakudala kwakucingwa ukuba liLanga elihambileyo hayi uMhlaba.
Kukho imiphakathi emininzi ethi, ukususela kumaxesha amandulo, yanikezela inkolo ekhethekileyo kwizinto zendalo. Kwinkoliso yazo, iLanga yayiyeyona nto idumileyo, kuba yayiyeyona ikhanyisela imihlaba yethu kwaye yanika ukukhanya kwizityalo. Isifundo sokuhamba kwabo sisebenzele ukwenza iwotshi zakudala apho iiyure zazisekwe kwindawo iLanga esibhakabhakeni ekupheleni kosuku.
Yiyo ke le ndlela kuphakanyiswe ngayo ukuma kwelanga kunye nokuziphatha kweentsuku. Kule mihla, Siyazi ukuba inani leeyure zokukhanya kwemini esinalo liyahluka phakathi kwamaxesha onyaka. Oku kungenxa yokuba Ukujikeleza, ukuguqulela kunye nokuhamba komhlaba. Ukongeza, eyona nto isichaphazelayo kubushushu nakwingqele kuthambekele ekubeni imitha yelanga ibethe umphezulu woMhlaba hayi umgama phakathi koMhlaba kunye neenkwenkwezi.
Oku bekusoloko izazinzulu zingenakuphumla, kude kube kamva kwafumaniseka ukuba nguMhlaba ohambayo hayi iLanga. Nangona kunjalo, liphuma phi iLanga kwaye libeka phi? Kuxhomekeke kwisimo sombonisi, ngaba ingatshintsha okanye lukhetho olungenakusilela ukusikhokela kwaye siqhelise?
Amanqaku ekhadinali
Ubumnyama buhlala bunxulumene nobubi kunye nokuziphatha okungalunganga. Ngesi sizathu, iLanga liye lafundwa ukusukela kwimpucuko yakudala. Babesoloko bezibuza ukuba liphuma phi ilanga, nangona kubonakala kusengqiqweni, akunjalo.
Kulapho umsebenzi ungena khona amanqaku eKhadinali. Yinkqubo yesalathiso esinceda ukuba sizikhokele emephini kwaye sazi ukuba masiziqhelise njani ngalo lonke ixesha. La manqaku aphambili abekwe emgangathweni kumanye amazwe, ukuze afane kuye wonke umntu. La manqaku asemgangathweni akumgangatho wekhadinali ngala: Mntla, Mzantsi, Mpuma neNtshona.
Ngokwethiyori, ilanga liphuma eMpuma lize litshone eNtshona. Silivile eli lizwi lisitsho kwizigidi zabantu. Ukuba silahlekile phakathi ebaleni, ngokuqinisekileyo umntu uya kuthi "Ilanga liyaphuma eMpuma lize litshone eNtshona." Nangona kunjalo, akukho lula kangako ukwazi, kuba kukho ukungangqinelani okunokusenza sithandabuze le ngxelo.
Ilanga liphuma phi ngokwenene
Kuya kufuneka uyazi ukuba iLanga liyaphuma eMpuma njengoko kuhlala kusitsho, kodwa ikwenza kabini ngonyaka. Kungenxa yokuba ukuthambeka komhlaba kunye nokujikeleza kwawo kunye nokuhamba kuguqulela kwenza amanqaku aphambili apho ilanga liphuma khona abasoloko bekwindawo enye.
Xa usithi ibekwe eNtshona, kuyakwenzeka ngendlela efanayo neMpuma. Iphuma kabini ngonyaka. Oku kunxulumene noko sele sikukhankanyile ngasentla malunga nobude beentsuku kumaxesha onyaka onyaka. Kuxhomekeke kutyekelo apho imitha yelanga ifikelela kumphezulu womhlaba kunye nentshukumo yokuguqulela uMhlaba onomzuzwana othile wokujikeleza kwawo, Ilanga liza kuphakama lisondele kwindawo ephambili eMpuma okanye hayi. Wenza kuphela ngokuchanekileyo kabini ngonyaka, ngexesha lentwasahlobo kunye nokuwa kweequinox.
La ngamaxesha apho uMhlaba ulungelelaniswe ngohlobo lweLanga ukuze imitha yalo ikwazi ukuphuma ngokugqibeleleyo eMpuma kwaye isete eNtshona.
Ukubaluleka kwee-equinox kunye ne-solstices
Ukuze ukwazi ukuphuma nokutshona kwelanga, ii-equinox kunye ne-solstices zizinto ezibaluleke kakhulu. Ngexesha lentwasahlobo kunye nokuwa kweequinox Ngaba kuphela kwemizuzu emibini apho imitha yelanga isifikelela ngokungxama kangangoko kunokwenzeka kumphezulu womhlaba. Kwelinye icala, ngexesha le-solstices, sinokubona ukuba sinemitha ethambekele ngakumbi kunangaphambili.
Ezi zinto zithathelwa ingqalelo ukulazi inani leeyure zokukhanya kwelanga esiza kuba nazo imini yonke nasekupheleni kwamaxesha onyaka. Ke ngoko, kubalulekile ukulungisa iindawo eziphambili kunye nokwazi kakuhle indawo yoMhlaba ngokubhekisele kwiLanga kwindlela yalo yokuguqulela ukuze wazi ngqo apho iLanga liza kuphuma khona.
Ngexesha lokuphela konyaka elingelilo iiquinox, iLanga liphuma ngaphesheya ngentla entwasahlobo nasehlotyeni, ngelixa iinyanga ukuwa okubandayo kunye nobusika kuya kuphuma kujonge ezantsi.
Njengoko ubona, ayisiyiyo yonke into emnyama nomhlophe kwi-astronomy. Kananjalo ayinakuchazwa ngokuchanekileyo into yokuba iLanga liyaphuma eMpuma nokuba litshona eNtshona. Ke, ukusikhokela ebaleni, singasebenzisa ezinye iintlobo zeempawu ezinokuthenjwa ngakumbi okanye silinde de kube amaxesha asondele kakhulu kwii-equinox.
