Yakaputirwa nemamiriyoni makiromita echando, nyika inogara isina vanhu uye, maererano nezvibvumirano zvenyika dzakawanda, haisi yevamwe vehurumende, pasinei nokuti munguva dzehondo dzehurumende vamwe vanoti vanozviti kune dzimwe nzvimbo huru muAntarctic.

Musangano wokutanga

Vatsva veAntarctica vakaziva vafambisi veRussia va Bellingshausen naLazarev, avo vaive vokutanga kudarika nyika yose, vachidaro vachisimbisa kuti iripo. Zvisinei, zita remazuva ano rekondinendi harina kuwana pakarepo. Pakutanga, mapiyona aya akaitumidza kuti "continent ice".

Chaizvoizvo, izwi rokuti "Antarctica" rinodzokera kune maGreek midzi ayo achiri kusangana naAristotle uye anoshandurwa se "kurwisana nechokumaodzanyemba", iyo inoratidza nzvimbo yayo yenzvimbo - shure kwezvose, ndiyo inyika yakadziva kumaodzanyemba panyika, iyo nzvimbo yepakati iri iri pedyo neSouth Pole.

Nyika ino ine nzvimbo yakaoma yakarongeka uye ndiyo yakakwirira kupfuura dzose kumakondinendi, izvo zvinoreva kuti ine kukwirira kwepakati pepamusoro pegungwa kupfuura kune dzimwe makondinendi. Kunyange zvakadaro, zvikomo zvose izvi zvakavanzwa pasi pechando, uye dzimwe nguva zvinosvika kuhupamhi hwemakiromita akawanda.
