Yonke indawo yeplanethi yoMhlaba iqukethe izikhala zamanzi ze-World Ocean kanye nezwe lamazwekazi asezwekazi. Amazwekazi asendaweni yonke aphansi kakhulu kolwandle nolwandle. Izilwandle ezine - i-Pacific, i-Arctic North, i-Indian ne-Atlantic-zithatha cishe amaphesenti angama-71 emhlabeni, futhi indawo yamazwekazi i-29%, ngokulandelana. Leli zwe liqukethe izindawo eziningi ezakha izingxenye zomhlaba. Kunezinyanga eziyisithupha kuphela: i-Asia, i-Afrika, iMelika, i-Europe, i-Antarctica ne-Australia ne-Oceania. Izingxenye eziyisihlanu zokuqala zomhlaba zimelela amazwe anesimo esithile, ehlukanisiwe, ehlonishwa ngokusemthethweni imingcele eyamukeleke emhlabeni jikelele. Ingxenye yokukhanya kwe-Australia ihlanganiswa yi-Oceania, isifundazwe esiqhingini esingenakubalwa njengengxenye yezwe ngesimo sayo.
Izingxenye zomhlaba zihlukaniswe ngamazwekazi noma amazwekazi. I-America, njengengxenye yezwe, ihlukaniswe yaba amazwekazi amabili - eNyakatho Melika naseNingizimu. EYurophu nase-Asia, ngokuphambene nalokho, babumbene esimweni sezwekazi futhi izwekazi lase-Eurasia lavela . I-Afrika - yi-Afrika futhi ihlala, kungakhathaliseki ukuthi iyingxenye yezwe, ngisho nezwe. Kunjalo nange-Antarctica. Kodwa i-Australia ibizwa ngokuthi izwe eliseningizimu kakade ngaphandle kwesiqhingi sase-Oceania. Izimboni ngokuvamile azifaki lesi siqhingi, nakuba uhlanganisa indawo yazo zonke iziqhingi, uthola isibalo esimangalisayo. Futhi ngaphandle kwalokho, lesi siqhingi, esikhulu noma esincane, empeleni siyingxenye yezwe.
Ngokushesha ngemva kokuhlukaniswa komhlaba wonke umhlaba emhlabeni, izingxenye zomhlaba zezingxenye zezwe ezisezwenikazi zenzeke. Ngenxa yalokho, kunamazwekazi kanye nezingxenye zomhlaba emhlabeni. Izwekazi elikhulu kunawo wonke i- Eurasia, indawo yalo engamamitha ayizigidi eziyizigidi ezingu-55. Amakhilomitha. Khona-ke kufika izwekazi lase-Afrika, izigidi ezingu-30. Okwesithathu yiNyakatho Melika, enezindawo ezingamamitha ayizigidi ezingu-20. I-Km. ENingizimu Melika, le ndawo isincane kakhulu, izigidi eziyizigidi eziyizigidi ezingu-18. I-Km. I-Antarctica - 14 ne-Australia - 8.5 million amamitha square. Amakhilomitha ngokulandelana. Ngaphezu kwalendawo, amazwekazi ahluke endaweni ephakeme ngaphezu kolwandle, kunokuhlukahluka okukhulu kule nkomba. Izwekazi eliphakeme kunazo zonke emhlabeni li-Antarctica, amamitha angama-2200 ngaphezu kolwandle, e-Asia ngamamitha angu-950, i-Afrika yi-750, iMelika ngo-650, i-Australia yi-340 neYurophu ngamamitha angu-300 ngaphezu kolwandle.
I-Asia - ingxenye enkulu kunazo zonke emhlabeni, indawo yayo ingaphezu kwamamitha ayizigidi ezingu-43 ezigidini. Amakhilomitha. Ngokubambisana kweYurophu, i-Asia yalahlekelwa isikhundla sayo njengengxenye yezwe futhi yaba izwekazikazi. E-Asia, kunamanye amazwe amaningana anabantu abangaphezu kwezigidi eziyizinkulungwane ezine. I-Asia ihlanganisa cishe zonke izindawo zezulu, kusukela e-equatorial eningizimu kuya e-Arctic enyakatho. Kanye ne-Europe, i-Asia yakha izwekazi lase-Eurasia. Ukukhululeka kwezwekazi lihlukile, kanye nezintabeni ezinkulu e-Eurasia kunezintaba ezinkulu zezintaba, i-Himalayas, iTien Shan nePhamir.
Ngokuphambene namagquma asezintabeni, e-Eurasia kukhona ukudonsa okujulile. Isibonelo, uLwandle Olufile, emngceleni we-Israel neJordani, lusezingeni elingaphansi kwezinga elwandle elingaphezu kwamamitha angu-400. Izwekazi lase-Eurasia lihlobo lomrekhodi emibonweni yezwe. Eurasia yiyona echibi elikhulu kunawo wonke emhlabeni - iCaspian, iLake Baikal - indawo engokwemvelo enamanzi amasha ahlanzekile, everest - intaba ephakeme kunazo zonke zeplanethi, ubukhulu obungenakuqhathaniswa nenhlonipho ye- Peninsula yase-Arabia, isiqu se-Oimyakon ebanda futhi ekugcineni, indawo enkulu kunazo zonke eMvelo - eSiberia.
