Indlela ukuqonda ibinzana elithi "ilanga bade"

Ngenye imini ezishushu zasehlotyeni, xa ngaphandle Kusibekele yaye ediniwe ekubaleleni, ngokufuthi sisiva ibinzana elithi "ilanga bade." Xa ukuqonda kwethu oku ukuba umzimba wasezulwini imi kwindawo ophezulu kakhulu efudumeleyo, omnye Ukutsho ke ndithi, elitshisa umhlaba. Masizame uhlobo lwediphu eyaziwa encinane astronomi ingasebenza kweli binzana nendlela lokwenyaniso ukuqonda kwethu le ngxelo.

engumzekelo anenkululeko

Nokuba neprogram yesikolo, siyazi ukuba kwiplanethi yethu kukho ukufana ekuthiwa, ezingabonakaliyo (ecingelwayo) umgca. khona yabo ngenxa imithetho ezingundoqo geometry yemvelo, kunye nolwazi, njani ezi zinto ziyimfuneko ukuze siqonde indlela eyayimi ngayo yonke le khosi. Yahlulahlulwe yaba ezintathu umgca ibalulekileyo --ikhweyitha, le ndawo kunye Arctic Circle.

I-ikhweyitha

I-ikhweyitha kuthiwa akabonakali (eziqingqiweyo) umgca elahlula umhlaba wethu zifaka ezimbini twatse - kuMzantsi nakuMntla. Kudala kwaziwa ukuba Earth engekho iintsika ezintathu nakholwa kumaxesha amandulo, kwaye imilo ungqukuva yaye, ukongeza kwisindululo ujikeleza iLanga, lijikeleza phezu axis yayo. Kubonakala ukuba ukufana mde ehlabathini, ukuba ubude ezimalunga nama-40 amawaka km, -. Kuyinto-ikhweyitha. Enyanisweni, ukusuka kwindawo mathematical lwembono, yonke into icacile, kodwa oku kubalulekile ukuba kwendawo? Kwaye apha, xa sihlolisisa, kuvela ukuba inxalenye umhlaba, nto leyo ifumaneka phakathi efudumeleyo, ufumana ubushushu kakhulu elanga kunye nokukhanya. Oku kungenxa yokuba eli kummandla Umhlaba isoloko bakhangela ilanga, ngoko imitha eziwa phantse nkqo. Kulo kulandela ukuba iindawo ethandwa kwi planethi amaqondo obushushu aphezulu kunye khona umoya ubumanzi obukhatshwa ukudala uwase olomeleleyo. Ilanga at bade kwi-ikhweyitha kabini ngonyaka, oko kukuthi ngokupheleleyo luyabonakala ngqo phantsi. Umzekelo, oku akuzange kwenzeke into enjalo eRashiya.

ndawo

Kwi jikelele kukho ndawo eseMazantsi Northern. Kuyaphawuleka ukuba ilanga sele bade apha kanye kuphela ngonyaka - ngosuku ngenjikalanga. Xa ekuthiwa yasebusika - December 22, wajika waya ilanga kangangoko kunokwenzeka lo ikhweyitha wasezantsi, yaye ngoJuni 22 - phezu koko.

Ngamanye amaxesha, Southern kunye naseMntla ekweleenjiko zithiywe nakumakroza ezulu, ophezu umendo kwelanga kule mihla. Ngokomzekelo, ngokuqhelekileyo Southern ebizwa Tropic of Capricorn kunye North - Umhlaza (Disemba ne Juni ngokulandelelana).

izangqa polar

Arctic Circle ithathwa kubakho ukufana, ngasentla apho kuthiwa kwaphawulwa njengoko ubusuku polar okanye ngosuku. Indawo ekwizibanzi, ezo ke izangqa polar, nayo iye kakhulu ingcaciso yemathematika, kodwa thabatha 90 ° ukutyekela axis-langa. Kuba Umhlaba, eli xabiso lilingana izangqa polar 66,5 °. Ngelishwa, abemi ezinezinga ziingcathu akakwazi ukubona la. Kodwa ilanga ke bade kwi ngaxeshanye ehambelana Arctic Circle, isiganeko Kungokwemvelo ngokupheleleyo.

eyenzekayo zaziwe

Umhlaba akemi ngxi, ukongeza kwisindululo ujikeleza iLanga, yonke imihla lijikeleza axis yayo. Kulo nyaka, sibona indlela ukutshintsha owehlayo kwemini, ubushushu umoya ngaphandle window, kwaye ingqalelo abaninzi uqaphele utshintsho indawo iinkwenkwezi esibhakabhakeni. Kuba 364 mihla Umhlaba uhamba umendo opheleleyo ngeenxa ilanga.

Imini nobusuku

Xa ebumnyameni, oko kukuthi ebusuku, kubhaliwe kwathiwa ilanga ngexesha lekhefu elinikiweyo maluquke ikhweyitha eyahlukileyo. Kukho kakhulu ngumbuzo ubhalo, kutheni namhla awunto elilingana nelo lokuqhubeka ebusuku. Inyaniso kukuba isikhokelo-moya ayikho engile ilungelo axis komhlaba. Enyanisweni, kule meko, asifuni ukuba namaxesha apho lulwahlulo ubude imini nobusuku utshintsho.

Ngemihla-20 kaMatshi, kwicala ilanga uyagoba iNorth Pole. Emva koko, emini emaqanda kwi-ikhweyitha, unako kanye ukuba ilanga sele bade. Olusemva kwezo ntsuku xa kwiindawo kumantla ngakumbi waphawula into efanayo. Ngomhla we 22 June ilanga bade ukwakweli Tropic of Cancer kwi kumntla ikhweyitha namhla kucingwa ukuba ibe phakathi ehlotyeni, kwaye nezide ubuninzi. injikalanga phenomenon - ukuzimisela yeyona eziqhelekileyo kakhulu kuthi.

Into enikisa umdla kukuba emva kuyenzeka kwakhona ngaloo mini yonke into, kodwa ukuze reverse, kwaye kuyaqhubeka de kube mzuzu xa umgca ukuya ikhweyitha emini enkulu, ilanga kwi bade kwakhona - oku kwenzeka nge-23 Septemba. Ngeli xesha, phakathi ehlotyeni buqala ikhweyitha esemazantsi.

Ukusuka konke oku kulandela ukuba xa ilanga sele bade kwi-ikhweyitha, ehlabathini ixesha lonke nobusuku - Iiyure ezi-12, ubude efanayo ixesha elilingana imini. Esithi sisetyenziswe ukubiza le nto ngomhla ekwindla okanye yasentwasahlobo.

Ngaphandle kwento yokuba ingcaciso echanileyo ingcamango 'ilanga bade, "siye saxubusha, kusesemini eqhelekileyo ngakumbi ukuba sibe amagama oko kuthetha ukufumana kanye ilanga phezulu kangangoko kunokwenzeka ngosuku elinikiweyo.
