Kungenzeka ukuthi ezinye zezinto ezilandelayo esizozidalula uzibuze wena. Lezo zinto ezinje ... "Kungani iminyaka iqonde kangaka?", "Kwenzeka kanjani ukuthi iNyanga ihlale ibekwe kahle kangaka?" Ngaphandle kobukhona bamandla adonsela phansi ... Kwenzeka kanjani ukuthi singaboni umehluko? Konke kulandela inkambo yakho, kepha kufana nokuba yinhlamvu yesihlabathi futhi uziqhathanise nentaba, asikwazi ukubona ngale, kepha ngokuhamba kwesikhathi, izinguquko bezilokhu zikhona.

Ngokwesibonelo, IHudson Bay eCanada ingesinye sezifunda lapho kunamandla amancane adonsela phansi. Kukhona imibono mayelana, ngokwesibonelo, iqhwa eligcinwe ngaphansi komhlaba.
Yebo, kungenzeka ukuthi abangaphezu koyedwa bacabanga ukuya ohambweni lapho ukuze bezwe ukuthi umphumela weNyanga wenzeka ngempela yini, futhi ukwazi ukushaya ukweqa okuntanta emoyeni. Ungayisindisa, ngoba iqiniso yilokho lokhu kwehluka kuncane kakhulu izikhathi ezingama-0,005.

Yilokho ngenxa yamandla adonsela phansi namandla amakhulu. Njengamanye amaplanethi. Isibonelo esihle sokubona lokhu ngeso lenyama yiJupiter, okuyiyo ebabazekayo kunayo yonke. Kuyisidlakela segesi esizungeza ngokushesha okukhulu.
Lokho yenza izingongolo zibhebhe, bese ziba banzi e-Ecuador.
3. Bewazi yini ukuthi phezulu kwe-Everest akuyona indawo eqhelelene kakhulu ukusuka enkabeni yeplanethi yethu?
Intaba iChimborazo
Ngokuhambisana nalokhu okungenhla, i-Everest, enamamitha ayi-8.848, iyindawo ephakeme kakhulu ngaphezu kwezinga lolwandle. Kepha hhayi esiseduzane nesikhala. Lesi sihloko sisekelwa yiMount Chimborazo etholakala e-Ecuador. Le volcano isengxenyeni "ebanzi kakhulu" yomhlaba. Isilinganiso se-GPS sikuqinisekisile ngo-Ephreli 2016. Indawo yayo ephakeme ukusuka enkabeni yeplanethi ingama-6384,4km uma kuqhathaniswa ne-6382,6km ye-Everest. Cishe u-2km ngaphezulu.
Uhlelo lwe-GPS lunomkhawulo wephutha elingu-10cm ngaphezulu noma ngaphansi. Futhi kunemininingwane efanele etholakele, njengokutholwa ngo-2001 ukuthi intaba ephakeme kunazo zonke eYurophu, iMont Blanc, ayilinganisi amamitha angu-4.807 kodwa amamitha angu-4810,4 XNUMX.
4. Bewazi yini ukuthi njengoba iminyaka ihamba, izinsuku ziba zinde futhi zibe zinde?
Lapho kwakhiwa uMhlaba Eminyakeni eyizigidi eziyizinkulungwane eziyi-4.500 edlule, izinsuku zazingamahora ayisithupha nje ubude. Y eminyakeni eyizigidi ezingama-620 nje edlule, usuku olulodwa lwadlula kancane Amahora angama-21 nohhafu. Namuhla, lezo zinsuku zihlala amahora angama-24 ngokwesilinganiso, izinsuku zandisa ama-millisecond angu-1,6 njalo ngekhulu leminyaka. Ngakho-ke kubantu besikhathi esizayo, izinsuku zizokwanda futhi zibe zinde.
Incazelo ososayensi abayitholile ngalesi simo ihlobene nokuzamazama komhlaba okukhulu kanye nama-tsunami umhlaba oke wahlupheka kuwo eminyakeni edlule, nokuthi kancane kancane wehlise isikhathi sokujikeleza kwawo.
5. Uyazi ukuthi iNyanga iyahlukana noMhlaba?
Njalo ngonyaka odlulayo, iNyanga ihlukanisa u-3,8cm isihlobo Earth. Kunombono weplanethi eyiwele kweyethu ebizwa ngeTheia, ecishe ilingane noMars. Lo mbono uthi lapho kwakhiwa uMhlaba, le planethi yashayisa eyethu. Ukusuka lapho, iNyanga yayizoba ncane futhi neyethu ibe nkulu.
Wake waqaphela ukuthi ukuzungeza kweNyanga kwiplanethi yethu kuhlangana ngesikhathi sokujikeleza kwayo? Yilokho okwenza ukuthi ngaso sonke isikhathi asibonise "ubuso" obufanayo.
