Kuyini, olwandle oluhlukanisa i-Afrika ne-Australia?

Ulwandle oluhlukanisa i-Afrika ne-Australia yi-Indian. Itholakala phakathi kwamazwekazi amane futhi, naphezu kokubhekwa njengowesifazane omkhulu kunazo zonke emhlabeni, yiyona ehlukahlukene kunazo zonke futhi ezithakazelisayo kusukela ekubukeni kwesayensi. Ake sibone ukuthi kuyini ngempela, olwandle oluhlanza i-Eurasia, i-Afrika, i-Australia ne-Antarctica, nokuthi amanzi ahluke kangakanani kwezinye izingxenye zomhlaba.

Ulwazi olujwayelekile mayelana noLwandle lwaseNdiya

Ulwandle lwesithathu olukhulu kunazo zonke emhlabeni luhlala ngamaphesenti angama-20 emanti alo. Umthamo wayo ungama-cubic kilometer angu-282.65, kanti iphuzu elijulile yi-Sunda Trench, ehla emamitha angu-7729. Iphuzu elisenyakatho laleli gaba elikhulu kunawo wonke lisendaweni yasePersian Gulf, futhi iningizimu-ntshonalanga isuke kunogwini lwase-Antarctica. Ulwandle oluhlukanisa i-Afrika ne-Australia linamakhilomitha ayizinkulungwane eziyi-10 phakathi kwamaphuzu aseningizimu kula mazwekazi amabili. Igama ngokwalo, okusobala ukuthi livumelana neNdiya, linikezwe emgodini ngaphandle kwalabo abakhileyo kulelizwe. Ngisho nangezikhathi zika-Alexander waseMakedon lawa manzi abizwa ngokuthi uLwandle lwaseNdiya, ngakho-ke lalibizwa ngama-Arabs, amaShayina namanye ama-ethnoses asendulo.

AmaLwandle kanye namaGulfs of Reservoir Indian

Indawo ephelele yezilwandle, lapho ulwandle oluphakathi kwe-Afrika ne-Australia lihlanganisa, yi-15%. Phakathi kwezinqolobane ezinkulu kakhulu uLwandle Olubomvu, uLwandle Lwase-Arabia (Persian Gulf), i-Bay of Bengal, uLwandle Lakadiv. Amathafa aseThailand ahlanjululwa yi- Andaman Sea. Kodwa ngaphandle kolwandle lwase-Australia, i-Timor ne- Arafura Seas kakade ngaphambi kwethu . Engeningizimu yiGreat Australian Gulf, futhi ngemva kwayo yizidumbu zamanzi eziseningizimu emhlabeni. Amanzi abo aphakathi kuka-Australia ne-Antarctica, ngoba ama-currents ngokuvamile abanda. Ngakho-ke, lezi yizilwandle zase Davis, Mawson, ulwandle lwe-Commonwealth kanye nolwandle lweCosmonauts. Ngezinye izikhathi bonke babhekwa nje kuphela oLwandle oluseningizimu, nakuba leli gama lingavamile ngokwesayensi.

Iziqhingi emanzini aseNdiya

Wonke umuntu uyazi ukuthi ulwandle oluhlukanisa i-Afrika ne-Australia lidumile ngeziqhingi zalo ezishisayo, okuyizindawo zokunethezeka nezindleko kakhulu zezinga lomhlaba. Kodwa phakathi kwezindawo ezincane zomhlaba ezitholakalayo kulawo manzi, ungathola futhi ugcwele ngokuphelele ngama-archipelagos asezindaweni ezishisayo, okuyizinto ezingenakwenzeka. Ngakho-ke, isiqhingi esikhulu kunazo zonke yolwandle iMadagascar. Ukuhlala kuso kuphephile, njengoba kunjalo, empeleni, ingxenye ehlangene ye-Afrika, eyayiyizwe elingaphambili. Ngokufanayo, leli zwekazi lase-Afrika liseduze neZanzibar. I-Australia nayo ihambele iziqhingi zamazwekazi, futhi enkulu kunawo wonke iTasmania, ilandelwa isiqhingi se-kangaroo, i-Queensland kanye nezinye eziningi. Iparadesi yezokuvakasha, ehlala e-Indian Ocean, i-archipelago ezimbili - iS Seychelles neMaldives.

I-Afrika yindlu yezwe lonke

Manje leli zwekazi lase-Afrika libhekwa njengelinye lezinto ezincane emhlabeni wonke. Nokho, ekuqaleni, ngezikhathi zangaphambili, kwakukhona, ngokusho kwesinye sezihumusho, isintu sazalwa, kanti ama-homosapiens njengezinhlobo zezilwane ahlala futhi athuthukiswa lapha izinkulungwane zeminyaka. Kungenzeka ukuthi kwenzeke ngenxa yesikhundla esihle kakhulu sezwekazi, ngaphandle kwalokho, ngaleso sikhathi isimo sezulu lapha sasingeke sikhulu futhi siphephe. Kumele futhi uqaphele ukuthi yiziphi izilwandle ezigezwa yi-Afrika. Ulwandle lwaso olusempumalanga lugezwa emanzini aseNdiya, futhi eNtshonalanga sibona i-Atlantic. Kumele kuqashelwe ukuthi yilolu phepho olusempumalanga yezwekazi elifanele kakhulu hhayi nje kuphela ngokuphila, kodwa nakwezokuvakasha. Amathafa wendawo, iziqhingi ezihlaba umxhwele ezihlanganisa ama-savanna namahlane, ukunqoba izinhliziyo zabo bonke abaza lapha.

Isiphetho

Njengoba kwenzeka, ulwandle oluhlukanisa i-Afrika ne-Australia, njengokungathi lithwala isiko namasiko alawo mazwe nabantu, emazweni afika kuyo. Emanzini ayo izwe elifanayo ligeleza, eduze kwalo yiChina, iThailand ne-Indonesia. Ngezansi lidlulela emaqenjini amaningi ase-Australia nase-gulfs, idlula i-Antarctica eNingizimu futhi ifinyelele emaphethelweni ase-Afrika. Cishe ngaso sonke isikhathi, i-Indian Ocean inhle kakhulu futhi ikhangayo. Amanzi ayo afudumele yonke indawo, ngaphandle kwezifunda eziseningizimu, ngakho-ke zonke iziqhingi ezikuwo zihle kakhulu ukuphumula nganoma yisiphi isikhathi sonyaka.
