Kuyini ebusika? ukuhlaziywa enemininingwane

Isihloko uchaza ukuthi lo ebusika, ukuthi kuyini, kuye ngokuthi indawo emhlabeni, futhi kungani kukhona zonyaka zishintsha.

Izinkathi zonyaka

Eziphilayo eplanethini yethu lapho, ngokusho izibalo abanye ososayensi ', iminyaka engaphezu kwezinkulungwane zezigidi 3 ubudala, futhi kulo lonke isimiso sethu sonozungezilanga, kuphela Umhlaba waba nenhlanhla ukuba imibandela ayezosebenza ngaphansi kwayo wokuthuthukisa kanye nokulondoloza impilo yemvelo. izici ezinjalo eziningi. Lokhu futhi khona namanzi, ibanga elithile kusukela inkanyezi emaphakathi, yesisindo, emkhathini, nokunye. N. Kodwa, kukhona nesinye isici, kuba Ukujikeleza planethi emhlabeni axis awo, lapho kukhona ukushintsha kwezinkathi zonyaka. Kanjani bona ngokwabo balandisa? Kakhulu elula, sibheke isibonelo Mercury efanayo. Leplanethi sisondele kakhulu Sun, futhi, ngaphandle kwalokho, njalo nje waphendukela uhlangothi, yingakho ohlangothini libalele we lokushisa awafike 500 degrees Celsius futhi ebusuku ebusa ebumnyameni baphakade isikhala abandayo. Ngakho, njengoba ungabona, njengoba izinkathi zonyaka abaluleke kakhulu. Futhi kulokhu sikhuluma ebusika. Ngakho, liyini ebusika?

definition

Ukuze uqale, ake ukubhekana imigomo. Winter - kungcono isizini abandayo, lapho izinga lokushisa kugcinwa esitebeleni ngezansi zero degrees Celsius futhi ngokuvamile snows. Uma uthatha le ebusika ikhalenda e Nenkabazwe, kuthatha izinyanga 3 - Disemba, ngoJanuwari noFebhuwari. Futhi eningizimu - Julayi, June no-August. Ngakho, manje siyazi ukuthi ebusika. Nokho, kungani benayo?

Ukuthambekela eksisi

Zonke daba Mechanics yasezulwini, eqinisweni, njengoba iplanethi uzungeza. Nge PERIODICITY ezithile Umhlaba kuyahlukahluka enyakazayo Axial mayelana indiza ye Ecliptic, ngoba Nenkabazwe uthola kancane ukushisa kwelanga, ngoba lokho nezinga lokushisa is kancane kancane kwehlisa, nalapho ukumelana layo lingaphansi 0 degrees futhi iqala langempela isikhathi ejwayelekile. Lokhu kubizwa ngokuthi ebusika yezinkanyezi e Nenkabazwe iqalisa kusuka 22 Disemba ukuze Mashi 21. Ngakho, saxoxa umbuzo lokho ebusika.

sezulu

Naphezu yezinkanyezi usuku ikhalenda ebusika, nenkathi ebandayo nge lokushisa engemihle futhi kwezulu yonke indawo kwenzeka ngezindlela ezahlukene. Ngokwesibonelo, emzaneni Russian of Oymyakon, kusukela ngo-Agasti 31, thermometer avame okushisa negative, okufanayo kusebenza nezinye izifunda Yakutia futhi Chukotka. Nokho, ngo-Primorye kanye laseKhabarovsk ngenxa ukusondela ukuba ulwandle, isimo sezulu ukuza onomoya omnene futhi kubanda, ngokulandelana, kamuva.

Ukuhlaziya umbuzo yini kusebusika, kuyafaneleka kokukhuluma imisinga ocean, okuyinto zidlala indima ebalulekile ngenxa yesimo sezulu. Ngokwesibonelo, eNetherlands, okuyinto wageza ngu Gulf Stream Isimo sezulu sikahle futhi athokomele, kanti Chukotka efanayo, ngenkathi cishe ku-latitude efanayo, iyahlupheka kakhulu onyakeni kusukela frost ezinzima nemvula.

ehlobo okuphakade

Emhlabeni, kukhona esishintshashintshayo lapho neze ebusika. Futhi iqiniso lokuthi abantu bendawo bathathele abandayo, nje abangele ukumamatheka e abakhileyo Nenkabazwe, futhi kuba - yenkabazwe. Nalapha futhi, ngenxa enyakazayo ukutsheka eMhlabeni, ushintsho zonyaka lapho cishe ingekho, kodwa zenzeka njalo ngezinkathi zemvula.

usuku Polar nobusuku

Kokubili enyakatho nensika eningizimu, kukhona ezimbili ngeqiniso elithakazelisayo kakhulu ebusuku polar kanye ngosuku. ebusuku polar ziyinkathi lapho ilanga ayisekho ngosuku, ngosuku into efanayo, kuphela in reverse - lapho ilanga lingashoni khona amahora angu-24. Isikhathi kulezi zinkanyezi sixhomeke kakhulu isikhathi sonyaka kanye latitude, kodwa isikhathi eside kunabo bonke ubusuku polar ihlala cishe izinyanga eziyisithupha njalo.

Naphezu kweqiniso lokuthi abantu baphile isikhathi eside e izenzakalo ezinjalo Basaba inethonya umuntu njengoba ngokwengqondo nangokomzimba. Phakathi kwabantu ebusuku ngokuvamile unesifo sokudangala abonakalisa ukushoda okukhulu kavithamini D.

Ngakho, kumelwe sikuqonde lokho ebusika, incazelo yegama njengoba sibonile.
