Ingabe i-Antarctica isuka kude ne-South Pole?

I-Continental drift ibangela ukuthi i-Antarctica ishintshe kancane indawo yayo eMhlabeni.

Njengawo wonke uMhlaba, i-Antarctica ithintwa "i-continental drift", isunduza ebusweni beplanethi yethu ukunyakaza okunyakazayo kwemisinga ejulile ekujuleni koMhlaba. Cishe eminyakeni eyizigidi ezingu-450 edlule, izingxenye ze-Antarctica empeleni zazisenyakatho yenkabazwe, futhi izwekazi lifinyelele endaweni yalo yamanje e-Antarctic eminyakeni eyizigidi ezingu-70 edlule noma ngaphezulu. Ngisho nangaleso sikhathi, isimo sezulu esifudumele emhlabeni wonke siye saligcina lingenaqhwa. Izinsalela zama-dinosaur atholakala lapho afakazela ukuthi isimo sawo sasithambile - laba ihlane elikhulu elineqhwa eminyakeni eyizigidi ezingu-20 edlule.

Imithelela ehlanganisiwe yoshintsho lwe geological kanye nesimo sezulu, nokho, ayikayeki, nakuba umsebenzi womthelela wazo e-Antarctica ugcwele ukungaqiniseki. Ngokwezibalo zesazi sokuma komhlaba uProfesa Christopher Success waseNyuvesi yaseTexas, i-Antarctica ingase isuke ngokuphawulekayo endaweni ekuyo futhi ingabi neqhwa kancane okungenani iminyaka eyizigidi ezingu-50 ezayo.
