Isizathu esiyinhloko salokhu ushintsho imini nobusuku

Izizathu ushintsho imini nobusuku basesimweni Ukujikeleza njalo futhi cyclical Zomhlaba emhlabeni axis awo. Le nqubo ngempela okusheshayo isikali yonke. Kodwa sinesikhathi ukuqaphela kusihlwa yakhe emnyama noma bebukela ukuphuma kwelanga ekuseni. Ngenxa imisebe yelanga lifudumeza ebusweni iplanethi, futhi siyabona ukuthi ukukhanya kushintshwa khona ebumnyameni.

I imisebe yelanga futhi ukukhanya inyanga

Izizathu ushintsho imini nobusuku kukhona ukuthi umhlaba uzungeza kuma-axis awo azungeze, singakwazi ngeso lengqondo. Kodwa ngesikhathi esifanayo ke uzungeza isihlobo ukuba ilanga. Lokhu kwenzeka ngesikhathi ukunyakaza orbit emhlabeni inkanyezi.

Izizathu ushintsho imini nobusuku basesimweni ezinyakazayo Zomhlaba ku edabula izinti-eksisi kule planethi. Ayiphethe ukuze ujike emahoreni angu-24. Kodwa Sun kuyinto Ukujikeleza kancane ngaphezulu - izinsuku ezingu-365.

Isizathu sokuba ushintsho imini nobusuku kuyinto ukujikeleza iplanethi. Emazweni ahlukahlukene isikhathi emini lihlukile. Ngokwesibonelo, eSt kuba nenkathi lobusuku esimhlophe izinsuku polar ingahlala ngaphezu kwenyanga.

Ngenxa okuyinto kukhona non-ukufana isikhathi ukukhanya kosuku?

Isikhathi imini nobusuku akufani yonke indawo ngenxa yokuthi eksisi ngengqondo Zomhlaba esitshekile kancane isihlobo ukuba ilanga. Ngakho-ke, imisebe iwe ngokungalingani ku ama- ezahlukene. Ngenxa ukuhanjiswa ukushisa futhi kukhona ukuphila emhlabeni.

Ukuphatha kudambe ebusuku, ngosuku iplanethi is iyazifudumeza. Wenzeka izinqubo ezibalulekile umzimba. Sibona Umhlaba endaweni ajwayelekile ifomu sibonga ezifana ukuhamba esiyingqayizivele amaplanethi. Emazweni ahlukahlukene yezimila nezilwane ezihlukahlukene zihlukile ngenxa ubude kosuku.

Pole kungenzeka emthunzini izinyanga eziyisithupha - kulokhu ngokuthi ebusuku polar. Bese kufika Ezinyangeni eziyisithupha ezalandela usuku esigxotsheni. Ngesikhathi lapho North Pole ebusuku, eningizimu - usuku, futhi okuphambene nalokho.

Uma bekungelona usuku evamile?

Ngenxa yokuthi Umhlaba nombala zikhanyiswa ilanga, kukhona ukuphila emhlabeni. Lapha ukucabanga ukuthi ababange ajikelezwe, futhi ngakolunye uhlangothi kuyohlale usuku, kanti eyesibili yayiyobizwa phakade bancishwa ukukhanya. Nenkabazwe phansi kwelanga kungaba red-hot lokushisa lapho bonke ukuphila kwawo kwakuyoba yomile.

Ingxenye yesibili emhlabeni owawuyoqala ngaso ukumisa ngenxa singakutholi ukukhanya kwelanga. Ngakho kule sinalo iplanethi ekahle yokuphila. Izinhlobonhlobo izidalwa eziphilayo kuyinto yesiteleka, futhi lokhu kungenzeka kuphela ngenxa ukujikeleza Earth. Shintsha kokubili imini nobusuku kubalulekile, kanye izinguquko sezulu ngenxa obhekwe zonyaka ezahlukene.
