Iziphepho zasolwandle, ezidume ngamandla azo namandla, zivela ngokungajwayelekile, kepha konke kuncike endaweni ethile yamanzi. Ucwaningo olwenziwe ososayensi baseYurophu luqinisekisa ukuthi kunamathuba okwanda kokuvama kweziphepho kanye namagagasi amakhulu amakhulu ogwini lwasenyakatho yeYurophu nakwamanye amazwekazi. Lokhu kwenziwa ukuqiniswa komthelela wokubamba ukushisa emhlabeni.
Ukuhlaziya imvamisa yamaza aphakeme nalawo aphansi, ushintsho emazingeni amanzi nobungako bamaza esiphepho, ososayensi abavela emazweni ahlukene bafinyelele esiphethweni sokuthi amazinga olwandle olwedlulele aya ngokuya edala izikhukhula ezibhubhisayo ezidlula nemiphefumulo eminingi. Ugu lwaseYurophu, ngokusho kwesibikezelo sabaphenyi, lusondele ngokuyingozi kwizikhukhula ezibhubhisa izivikelo futhi zithathe izakhiwo zokuhlala, izakhiwo zomphakathi nezinsiza olwandle. Esinye sezibonakaliso ezethusayo zokwanda okukhulu kwenani lamanzi olwandle olusongela isintu yilokho okubizwa ngokuthi "izikhukhula zelanga" esifundazweni saseMelika iFlorida, lapho ngosuku olungenamoya igagasi lamanzi olwandle ezivikelweni ezisogwini liphezulu kakhulu.
Izimbangela eziyinhloko zokushintsha kwezinga lolwandle
Igama elithi "ngokulingana nolwandle", elaziwa yibo bonke abantu, liyalinganiselwa impela, ngoba ebusweni balo bonke, indawo enkulu yamanzi ayicabalele futhi ayifani. Ngakho-ke ogwini bunosayizi abehlukene, okuthinta ukubalwa kwabahloli bezwe abaphoqeleka ukuthi benze ukulungisa okufanele emsebenzini wabo lapho beklama izakhiwo. Izici ezilandelayo zithinta ushintsho ezingeni loLwandlekazi Lomhlaba:
- izinqubo ze-tectonic ku-lithosphere. Ukuhamba kwamapuleti we-tectonic kuholela eqinisweni lokuthi phansi kolwandle kuyacwila noma kukhuphuke ngenxa yezinqubo zangaphakathi kwi-lithosphere;
- izinguquko kumandla kazibuthe womhlaba, zidala izivunguvungu zamandla angajwayelekile;
- izinqubo zentaba-mlilo ezihambisana nokudedelwa kwesisindo esikhulu esincibilikisiwe samatshe e-basalt futhi kubangele ama-tsunami;
- umsebenzi womnotho womuntu, okwaholela ekuncibilikeni okukhulu kweqhwa lekhava nokuqoqwa kwamanzi afriziwe ezigxotsheni.
Isiphetho sabososayensi
Ososayensi emhlabeni jikelele bakhala inhlabamkhosi, bachazela ohulumeni bazo zonke izifundazwe ngobungozi bokukhishwa okungalawuleki kwamagesi asindayo emkhathini womhlaba, okwenza kube nomphumela wokushisa okushisa. Ngokuya kocwaningo lwabo, ukuqhubeka kwesimo esinjalo sobuqaba emvelweni kungaholela ekukhuphukeni kwezinga lolwandle lomhlaba ngemitha eli-1 emashumini ambalwa nje eminyaka!
