Besisoloko siyazi iplanethi yethu njenge “planethi eblue” kwaye ngoku umthamo wamanzi okhoyo kulo Mhlaba wethu awunanto yakwenza nawo xa kuthelekiswa nezigidi zeminyaka eyadlulayo. Okwangoku iilwandle zomhlaba wethu zihlala ngaphezulu kwama-70% omhlaba wethu kwaye zintlanu zizonke apho siqaqambisa ezintathu eziphambili, oko kukuthi, iAtlantic, iIndiya kunye nePacific. Nangona kunjalo, namhlanje ndifuna ukukuxelela okungakumbi malunga nabo ukuze ukongeza ekubazini ngolwazi oluthe gabalala, ungazi ukuba zithini iiodolo zabo ngokolwandiso lwabo.
Kukho ulwandle olunye kuphela

Nangona kweli nqaku ndifuna ukukunika iinkcukacha ngokubanzi zolwandle olu-5 olukhoyo kwiplanethi yethu, inyani kukuba zonke ezi-5 zikulwandle olunye, kodwa kuxhomekeke kwindawo abakuyo, bafumana igama elahlukileyo ukuze babenako ukubabona kakuhle.
Ngelixa kukho ulwandle olunye kuphela, isixa esikhulu samanzi esigubungela iipesenti ezingama-70 zomhlaba, kodwa ngokwahlulwa ngokweendawo ngokweendawo. Imida phakathi kwale mimandla iguqukile ngokuhamba kwexesha ngenxa yezizathu ezahlukeneyo zembali, zenkcubeko, zejografi kunye nezizathu zesayensi.
Ngokwembali, bekukho iilwandlekazi ezine: iAtlantic, iPacific, iIndiya kunye neArctic. Nangona kunjalo, uninzi lwamazwe- kubandakanya i-United States-ngoku ikwaqaphela uLwandle lwaseMazantsi (Antarctica) njengolwandle lwesihlanu. Kodwa iPacific, iAtlantic kunye neLwandlekazi lwaseIndiya zaziwa njengolwandlekazi olukhulu lweplanethi ngenxa yolwandiso lwazo olukhulu.
I-Antarctic Ocean lulwandle olutsha, kodwa ayingawo onke amazwe ayavumelana ngemida ecetywayo kolu lwandle (luqala kunxweme lwe-Antarctica), kodwa kungoku nje lulwandle lwesihlanu kwaye kufuneka kuthathelwe ingqalelo ukuze ukwazi ukubabiza bonke. Emva koko ndiza kuthetha nawe kwimigca ngokubanzi ukuze wazi ngakumbi malunga nolwandle ngalunye olukhoyo kuphela kuLwandlekazi olukhulu.
ipacific Ocean
Ulwandiso: 166.240.992,00 yeekhilomitha ezizikwere.
Olona lwandle lukhulu kwiplanethi yethu luthatha isinye kwisithathu somhlaba kwaye sisuka eArctic emantla siye eAntarctica emazantsi kwaye silikhaya leziqithi ezingaphezu kwama-25.000, elingana ngaphezu kwazo zonke ezinye iilwandle ezidibeneyo. Ulwandlekazi lwePasifiki luhlala kwiipesenti ezingama-30 zoMhlaba kwaye lubekwe phakathi kwamazwe aseMelika ukuya kwiMpuma yeLwandlekazi lwePasifiki kunye namazwekazi aseAsia naseAustralia ukuya eNtshona. I-ikhweyitha iyazahlula kuLwandlekazi loMntla wePasifiki nakuLwandlekazi lwePasifiki yoMzantsi.
Igama livela kwigama elithi "uxolo", ndafumana eli gama kumhloli wamazwe wasePhuthukezi uFernando Magellan ngo-1521 abiza la manzi "yiPacific Ocean" nto leyo ethetha ulwandle olunoxolo. Iilwandle zalo ziye zawela iinqanawa ezininzi kwimbali.
Ulwandlekazi lweAtlantic
Ulwandiso: 82.558.000,00 yeekhilomitha ezizikwere.
Okwesibini kulwandiso lusuka kumantla oLwandlekazi lwe-Arctic ukuya kuLwandlekazi lwe-Antarctic esemazantsi, luhlala kwi-20% yomhlaba wonke. Ukongeza koku, kwaziwa ngokuba lolona lwandle lincinci kubo bonke, olwenziweyo malunga neminyaka engama-200 yezigidi eyadlulayo xa ilizwekazi eliphambili iPangea lahlukana phakathi.
I-ikhweyitha yahlula uLwandlekazi lweAtlantic kuLwandlekazi lweAtlantic kunye noMazantsi oLwandlekazi lweAtlantic. kwaye iphakathi kwamazwe aseMelika kunye namazwekazi aseYurophu naseMpuma Afrika. I-ikhweyitha yahlula uLwandlekazi lweAtlantic kuLwandlekazi lweAtlantic kunye noMazantsi oLwandlekazi lweAtlantic.
Zininzi iziqithi kuLwandlekazi lweAtlantic, phakathi kwezona zaziwayo zezi: IBahamas, iCanary Islands (iSpain), iAzores (iPortugal), iCape Verde Islands, iGreenland, engezizo ezona ziqithi zinkulu kuLwandlekazi lweAtlantic, kodwa nasemhlabeni.
Igama elithi 'Atlantic' livela kwiintsomi zamaGrike elithetha 'uLwandle lweAtlas'. I-Atlas yayiyi-titan ekwakufuneka ibe semdeni womhlaba kwaye ithwale amazulu (amajukujuku asezulwini) emagxeni akhe njengesohlwayo esinyanzelwe nguZeus okoko iAtlas yayilwile noothixo baseOlimpiki ukuba balawule amazulu.
Ulwandlekazi lwaseIndiya
Ulwandiso: 75.427.000,00 yeekhilomitha ezizikwere.
Ukugubungela phantse i-20% yomhlaba, i-Indian Ocean inoxanduva lokuhlamba amanxweme oMbindi Mpuma, uMazantsi eAsia, iAustralia, iMpuma Afrika kunye noMzantsi mpuma weAsia.
Zininzi iziqithi kuLwandlekazi lwaseIndiya, phakathi kwezona zaziwayo zezi: IMauritius, iReunion, iSeychelles, iMadagascar, iComoros (iSpain), iMaldives (iPortugal), iSri Lanka, eyayisaziwa njengeCeylon. Igama livela kwindawo ejikeleze usingasiqithi waseIndiya.
Ulwandle lweAntartic
Ulwandiso: 20.327.000,00 yeekhilomitha ezizikwere.
Ulwandle lokugqibela olwandisiweyo yi-Antarctic Ocean, ejikeleze ngokupheleleyo iAntarctica, ijikeleze ngokupheleleyo umhlaba, kanye njengoko kusenza iArctic Ocean. Olu lwandle lukwabizwa ngokuba luLwandle lwaseMazantsi.
Ulwakhiwo lolwandle lubandakanya ishelfu yelizwekazi ubuncinci eyi-260 yeekhilomitha ububanzi efikelela kububanzi beekhilomitha ezingama-2.600 kufutshane neLeddell kunye neRoss Seas.
Ulwandle lweArctic
Ulwandiso: 13.986.000,00 yeekhilomitha ezizikwere.
Okokugqibela kodwa kungaphelelanga apho, sinolwandlekazi i-Arctic, olunoxanduva lokujikeleza iNyakatho yePole, ukubamba iziqwenga zomkhenkce unyaka wonke. Oku kubekwe emantla elizwekazi lethu, iAsia neMelika. I-Arctic Ocean yeyona incinci kuzo zonke iilwandlekazi kodwa ineelwandle ezingaziwa kangako ngenxa yemozulu enobutshaba kunye nomkhenkce unyaka wonke ogubungela iilwandle.
Phantse kungabikho mda, uLwandlekazi lweArctic lunqamlezwe yiGreenland, Canada, Alaska, Rashiya neNorway. I-Bering Strait iqhagamshela kuLwandlekazi lwePasifiki kunye noLwandle iGreenland lolona qhagamshelo luphambili kuLwandlekazi lweAtlantic.
Ummandla womkhenkce woLwandlekazi iArctic uyancipha ngesi-8% rhoqo kwiminyaka elishumi. Sonke kufuneka sazi ukuba kwenzeka ntoni ngotshintsho lwemozulu kwaye sikhusele iplanethi yethu.
