Iqela ngalinye linokukwenziwa Ocean - ukuba isiziba yonke

Amanzi kubalulekile ukuba zonke izidalwa ukuze siphile. Oku akumangalisi, emva kokuba onke, weza ubomi emhlabeni bethu baphuma emanzini. Amanzi abagubungela ngaphezulu kwe asixhenxe ekhulwini phezu komhlaba wethu.

Isahlulo phezu kolwandle

Yonke imithombo yamanzi le planethi zenza elwandle. Inxalenye elwandle ezikhoyo kulwalamano olusondeleyo nabanye. Icandelo inkulu kwemithombo yamanzi lwenziwa phezu elwandle, apho kukho ezine ehlabathini: i-Pacific, Atlantic, Indian kunye Arctic. Ezinye zokuma badla ukongeza kule uluhlu ezintlanu - Southern, eqamba njengamanzi ngeenxa Antarctica. Kodwa ke uninzi unyanzelisa ezine kuphela. Yaye elwandle, iindawo kunye sezingxakini - ndawo yolwandle. Oku kuthetha ukuba ngamnye babeziindleko ezine ingxilimbela amanzi inamacandelo yayo. imida yolwandle zikhona phantsi kwemiqathango ethile kuphela. Kwelinye icala, oko kuyinxalenye nemisinga kunye siqithi, yaye enye - loo enxibelelana kunye namaza kulo mhlaba.

Le etymology igama

Kolwandle bamazwe yokuqala eYurophu inkulu ehlabathini babona Magellan kwinkulungwane yeshumi. Lonke ixesha ehamba ezi amanzi ezolile, ngoko yena igama - Pacific. Kunye namagama abanye iilwandle ecacileyo. Atlantic got igama layo emva edume Atlanta - iqhawe kwiintsomi zamaGrike, lowo wayephatha isibhakabhaka emagxeni akhe intlomo ngasentshonalanga lweMeditera. Zonke amanzi, akhiwe ukuya ngasentshona, ngenkulungwane elinesixhenxe wafumana igama hero bangafi. I-Indiya waqalisa ekuthiwa, kakhulu, ngenxa kwabaseRoma amandulo kuphela. UPliny ngaphambi kwexesha lethu kwiincwadi zakhe ebizwa ulwandle imbeko edumileyo ngaloo mihla, kumazwe asempuma; kodwa igama eqhelekileyo kuphela kwinkulungwane yeshumi, emva kokuba ukhenketho yehlabathi yokuqala. Igama Russian "Arctic" yavunywa kuphela kwinkulungwane yamashumi amabini; ngokuba ngaphandle indawo icandelo osemantla olwandle - ukuba ezihambayo. Ngoxa ezininzi kumazwe Western, ibizwa ngokuba nje Arctic ukususela ngenkulungwane ye-yeshumi elinesithoba.

ulwandle iplanethi

Sea, zokupaka kunye sezingxakini kummandla lilonke iilwandle ubambe ukusuka elinesihlanu elinesibhozo ekhulwini. Ukuphela: i-Arctic, i indawo ezibandaknywayo apho ngaphezulu kwe asixhenxe ekhulwini. Uninzi ihlukane ndawo yolwandle - kuba ulwandle. Bona ezahlulwe iinxenye lizwekazi, okanye iziqithi eziphakamileyo zasemanzini omnye ngaloo ndlela ezahlukeneyo imiqondiso amanzi aseleyo - umgangatho ophelelwe lobushushu okanye nemisinga. Ngokusekelwe iqondo Umgama ukusuka elwandle amanzi olwandle ukuba litheni (Barents), yangaphakathi (lweMeditera) kunye inter-siqithi (Philippine). Le ngaphandle kuphela ukusuka kuluhlu - eLwandle Sargasso, egqiba igama elifanayo lisiza. Pacific Ocean ithatha indawo enkulu. indawo yayo phantse amahlanu ekhulwini yonke umphezulu amanzi. Ngoko ke, inxalenye Pacific Ocean zezona enkulu kangakanani na, ngaphezu ubukhulu zincinane - i-Arctic - in izihlandlo ezimbalwa.

Bay kunye neentlobo zabo

Bay - ayinakuthelekiswa kunye neendawo kweelwandle indawo yamanzi, ziza kweli lizwekazi. Kodwa ke amacandelo ingcamango "Ulwandle". Inxalenye Yehlabathi Ocean, leyo niphuphuma iinto coves - kule esibhakabhakeni kummandla Atlantic kumanzi zaseYurophu Nordic malunga Canada naseRashiya. Xa ekulinganisweni neelwandle lonikezelo mkhulu, ngokubhekiselele ubuninzi, indawo yokuqala iya kuba ngokuqinisekileyo matheku. Ngapha koko, lo hlobo ibandakanya zonke zokupaka, amawa, amachweba, amachweba.

Nditsho ke wokuqala owabona Pacific Ocean European - umnqobi Spanish - bayibiza ulwandle Southern, ngokuba emehlweni lokuvula kuphela bay. Kukho, Kakade ke, kwanamatheku ezinkulu, ezifana Bengal okanye Mexico, kodwa uninzi lwazo ezincinane kakhulu. Ukuba bayavuma ngokokubona ukuba iilwandle ze umhlaba malunga zaba ngamashumi omathandathu, matheku yi-odolo ezininzi sezingeni elikhulu, kodwa ngqo inani count phantse akunakwenzeka. Kwaye ke nani likhulu zokupaka - iinxalenye zecandelo le-Atlantic Ocean.

Okubandezeleka yendalo neyenziweyo

Basala ebizwa kunokuba hayi ngokubanzi ezilwandle leyo emida iinkalo ezimbini mhlaba, kodwa kwangaxeshanye qhagamshela kwemithombo ezimbini. Basala lahlulwe ububanzi, ubunzulu, ubunzulu, kwaye kananjalo bejonge yintshukumo yamanzi. Bona zimxinwa kakhulu, ezifana i Bosphorus phakathi Black and Marmara kweelwandle, kunye ububanzi nje anamakhulu asixhenxe eemitha, yaye ububanzi kakhulu, njengoko Drake Passage phakathi Atlantic kunye neelwandle Pacific nobubanzi engaphezu kwewaka kweekhilomitha.

Ngaphezu koko ukuchitheka, kukho omnye izithuba uhlobo compound zolwelo esisodwa ngokufanelekileyo phakathi kwabo. Kodwa asiyiyo inxalenye olwandle. Ezi ze ezenziwe eyakha uluntu ukuze kukhawuleziswe ukuhamba iinqanawa. Okokuqala, abantu abaye bangenela umlambo, yaye ngoko ulwandle. A imigangatho esanda zembali ukuba iilwandle mninzi. Eyona idumileyo ke Suez Canal, odibanisa lweMeditera kuLwandle Olubomvu, kunye nabo Atlantic kunye Oceans Indian, ngokunjalo ke iPanama Canal, leyo ibalekisa indlela ukusuka Atlantic ukuya Pacific Ocean.
