Ingxenye ngayinye ocean - kungcono ucezu iyonke

Amanzi ayingxenye ebalulekile zonke izidalwa ukuze isekele ukuphila. Lokhu akusona isimanga, phela eziphilayo eplanethini yethu kwaphuma amanzi. Amanzi asibekela izingane ezingaphezu kwamaphesenti angu ayisikhombisa ebusweni iplanethi yethu.

Lesi sigaba phezu izilwandle

Zonke imithombo yamanzi le planethi bakha izilwandle zomhlaba. Ingxenye izilwandle zomhlaba ezikhona ubuhlobo obuseduze nomunye. Lesi sigaba ngobukhulu kwemithombo yamanzi kwenziwa izilwandle zazo zikhona ezine emhlabeni: Pacific, Atlantic, Indian kanye Arctic. Ezinye zokuma kwendawo bavame ukuze ungeze kule uhlu emihlanu - Wik, uqambe njengoba nje amanzi emhlabeni Antarctica. Kodwa iningi ephikelela ezine kuphela. Futhi kolwandle, amatheku futhi becindezelwe - ingxenye olwandle. Lokhu kusho ukuthi ngamunye expanses ezine giant yamanzi has izingxenye zalo siqu. imingcele Oceanic khona ngokwemibandela kuphela. Ngakolunye uhlangothi, iyingxenye ezweni nemisinga eya lesi siqhingi, futhi ngakolunye - ke ofana futhi meridians planethi.

I etymology kwegama

Olwandle wabahloli zokuqala zaseYurophu elikhulu kunawo wonke embusweni wabona Magellan ngekhulu leshumi nesithupha. Ngaso sonke isikhathi sakhe luhamba lezi amanzi aba ezolile, ngakho got igama - Pacific. Nge amagama kwezinye izilwandle ecacile. Atlantic lethiwa emva Atlanta edume - hero zamaGreki, ngubani yayiphethe esibhakabhakeni emahlombe akhe e de entshonalanga iMedithera. Zonke amanzi, elise entshonalanga, ekhulwini lesikhombisa wathola igama iqhawe wasenganekwaneni. Indian waqala ubizwe ngakho, futhi, sibonga amaRoma asendulo kuphela. UPliny ngaphambi kwesikhathi sethu esivamile emibhalweni yakhe ngokuthi ulwandle behlonipha futhi elalidume kunawo wonke ngalezo zinsuku, emazweni asempumalanga, kodwa igama kwaba into evamile ukuthola kuphela ngekhulu leshumi nesithupha, ngemva izinkambo yezwe yokuqala. igama Russian "Arctic" sivunyiwe kuphela ngekhulu leminyaka lamashumi amabili, ngoba ngaphandle indawo ingxenye esenyakatho ocean - kungcono izinguzunga zeqhwa. Nakuba amazwe amaningi aseNtshonalanga, kuthiwa nje kwe-Arctic kusukela maphakathi nekhulu le-nesishiyagalolunye.

iplanethi kolwandle

Sea, amatheku futhi becindezelwe endaweni Imininingwane kwezilwandle ubambe kusuka nanhlanu kuya amaphesenti ayishumi nesishiyagalombili. Okuwukuphela: Arctic, endaweni izingxenye ingxenye zazo ezingaphezu kuka amaphesenti ayisikhombisa. bathinteka kakhulu ingxenye ocean - kuba kolwandle. Basuke ahlukaniswe izingxenye zaleli zwekazi, noma iziqhingi kwamanzi eziphakeme futhi omunye ngaleyo ndlela ezahlukene izimpawu amanzi asele - lizinga usawoti, izinga lokushisa noma imisinga. Kususelwa degree of ibanga ukusuka olwandle ulwandle amanzi zingabantu abekelwe emaceleni (uBarents), yangaphakathi (iMedithera) kanye inter-isiqhingi (Philippine). Okuwukuphela ohlwini - Sea Sargasso, ukuthi inquma efanayo igama ulwelwe. Pacific Ocean ihlanganisa indawo enkulukazi. endaweni yaso cishe amahlanu amaphesenti yonke phezu kwamanzi. Ngakho-ke, ingxenye Pacific Ocean kukhona okukhulu kakhulu ngobukhulu, beyizidlova ngobukhulu komncane kunabo --Arctic - e izikhathi ezimbalwa.

Nezindawo zokupaka nezinhlobo zabo

Nezindawo zokupaka - kuncane kakhulu uma kuqhathaniswa ne kwezilwandle izindawo isikhala amanzi, okuyinto iyangena zwekazi. Kodwa bahlakaniphe izingxenye welithi "Oceans". Ingxenye Yezwe Ocean, okuyinto sichichime coves - lokhu emkhathini endaweni Atlantic emanzini European futhi Nordic emhlabeni Canada neRussia. Lapho ekulinganisweni izilwandle wokusabalalisa enkulu, ngokuya ambalwa, okokuqala kuyoba ngokuqinisekile amatheku. Phela, kuze kube yilolu hlobo kuhlanganisa wonke amatheku, amawa, izizalo zemifula, izindawo amachweba.

Ngisho ngowokuqala ababone ePacific Ocean-European - Spanish umnqobi - ukuyibiza kolwandle Southern, ngoba emehlweni kuphela kokuvula bay. Kukhona Yiqiniso, nasemathekwini omkhulu, ezifana Bengal noma eMexico, kodwa iningi lawo elincane kakhulu. Futhi uma ososayensi bayavumelana umbono ukuthi izilwandle planethi mayelana ayisithupha, amatheku by oda eziningana sezingeni elikhulu, kodwa Inamba yangempela ukubala cishe kungenakwenzeka. Futhi isibalo esikhulu amatheku - izingxenye ingxenye ka-Atlantic Ocean.

EStraits of zemvelo kanye yokufakelwa

Straits ngokuthi ukungakuboni ebanzi ulwandle nezilwandle zazo delimited ezindaweni ezimbili umhlaba, kodwa ngesikhathi esifanayo ukuxhuma amadamu amabili. Straits ehlukaniswa ububanzi, ukujula ukujula, futhi ohlangothini amanzi ukunyakaza. Ziyakwazi ewumngcingo kakhulu, ezifana lo Bosphorus iphakathi kolwandle Olumnyama futhi Marmara kwezilwandle, nge ububanzi amamitha eziyisikhombisa nje eziyikhulu, ububanzi kakhulu, njengoba Drake uMzila ophakathi kwe-Atlantic nePacific ukuze ububanzi ezingaphezu kwenkulungwane amakhilomitha.

Ngaphezu kwalokho spillage, kunesinye sasivumela esiyingqayizivele ifomu lemagalagala aqueous izikhala phakathi kwawo. Kodwa lokhu akulona ingxenye olwandle. Lezi ziteshi yokufakelwa eyakha esintwini ukusheshisa ukunyakaza lwemikhumbi. Okokuqala, abantu bajoyine umfula, bese kolwandle. A amazinga esanda kuqalwa womlando oluchazayo izilwandle. Isenzakalo esidume kunazo zonke kukhona Suez Canal, yokuxhuma ngamazwe aseMedithera nase uLwandle Olubomvu, futhi nabo Atlantic futhi Oceans Indian, kanye iPanama Canal, okuyinto ngesivinini ngendlela lisuka e-Atlantic ePacific Ocean.
