Iilwandlekazi zomhlaba kunye nokubaluleka kwazo

Malunga nama-75% ngaphantsi komhlaba yeyona iilwandle kunye neelwandle. Bathi ezingundoqo, iindinyana ezihambelanayo. wonke umhlaba kuthiwa iilwandle kwehayidrosfere. Ngenxa yoko, iilwandle komhlaba ziqulethe 97% awo onke amanzi.

Njani olwandle ehlabathini? Ihlabathi yahlulwe ezine. Le asidi zilandelayo: Pacific, Arctic, Atlantic namaNdiya.

Pacific ithathwa ukuba inkulu. indawo yayo malunga 166 ezigidi macala onke. leekhilomitha. Got igama layo emva kokuba waba ngowokuqala ukudada umhambi odumileyo Magellan. kwezibonelelo zamanzi Pacific Ocean phantse isiqingatha zolondolozo lwamanzi-langa. I enkulu ubude bayo - kuba-17 amawaka eekhilomitha. Oku phantse isiqingatha umhlaba. Kodwa igama lakhe ayingqinelani yokwenene. Akusoloko kuyinto entle kuphole. Ngenxa umsebenzi omkhulu seismic Lubonakala zizikhukula ezinkulu kunye neenyikima ezenza kube eyoyikisayo.

amanzi Pacific makahlambe ndawo komhlaba ukusuka eMpuma Asia ukuya eMelika, kuquka nonxweme lwaseAfrika. Ubunzulu amanzi alo lazo. Elona lincinane leemitha 120. Umlinganiselo kuluhlu kweemitha 4000. Ocean idume ezingaphakathi zengcwele ekhethekileyo on Earth, i-Mariana Trench, nto leyo ubunzulu kweemitha 11022. Emva kophando kwenzeka ukuba kukho izinto eziphilayo.

Uncedo of the Pacific kolwandle na isakhiwo ezahlukeneyo. Kukho abakhoyo emikhulu seamounts, kunye misinga ezininzi. On nommandla wayo kukho ezininzi iziqithi engabalulekanga mlilo. Ocean amanzi izele eziphilayo.

iilwandlekazi zomhlaba ukuba amaqhina oqhagamshelwano kunye nabanye. Ithatyathwa Atlantic yesibini ngobukhulu. indawo wayo 82 Mill. kwiikhilomitha Square. Ubunzulu omkhulu ulwandle ifikelela iimitha 9218. Embindini ummandla wayo yolula xitsunga enkulu kwamanzi. Atlantic Ocean kunempembelelo enkulu yezulu e-Europe.

Enye inkqubo ummeli ezibumba elwandle komhlaba, i-Indiya. indawo yayo -. million 73 ezikwere zeekhilomitha, lelona elikhulu wesithathu. Oku kungenziwa ngokuba ulwandle lobushushu. Kule nkalo, kuba ezininzi ezahlukeneyo izityalo amanzi kunye nezilwanyana. Ehlabathini kwisiqithi Java, nto leyo ifumaneka e-Indian Ocean, wafumanisa kumkhombe. Ukujula kwawo ifikelela iimitha 7450. Uphawu nolwandle utshintsho nokungena amanzi alo olungaphesheya. Oku kwenzeka kabini ngonyaka.

Indian Ocean uhlamba kunxweme ka East Afrika, India, Australia ne Antarctica. inyikima kwamanzi ukuba imzisele ukubunjwa ngaphezulu entabeni leyo ezivelileyo ngaphezu komhlaba kwaye enze nomxokelelwane iziqithi.

iilwandlekazi zomhlaba kwaye ziquka i-Arctic Ocean lincinci. Kubhaliwe ibekwe phakathi eSiberia Canada. osemqoka yalo ukuba inxalenye enkulu kumphezulu layo ligutyungelwe ngumkhenkce. Ngoko ke, lo ocean ayikho uphando alikazaliseki. Ubunzulu inkulu kweemitha 5000. Kufutshane kummandla kweshelfu Russian lizwekazi ibekwe. Sichaza kubunzulu omncinane zonxweme kweelwandle: kuLwandle Barents, i Chukchi, Laptev, Kara, East Siberian.

Ulwandle 3% iqulathe iityuwa kwezimbiwa lichithakale. Eli nani ingahluka. Umzekelo, ukuba amanzi kwe Dead Sea iqulethe-24% ityuwa. Kwakhona emanzini olwandle uza igolide. inani ogcweleyo likhulu kakhulu, kodwa ke konga iphantsi kangangokuba cishe akunakwenzeka ukuba ufumane.

elwandle siqulathe ulwazi oluninzi malunga umhlaba elidluleyo. zophando lwabo uyaqhubeka namhlanje. iilwandlekazi zomhlaba ubambe ezininzi iimfihlakalo kunye iimfihlelo. Abanye abantu ngezenzeko akakwazi ukusombulula ixesha elide. It is a uvimba kwezimbiwa kunye nezinye izixhobo eziyimfuneko ukuze abantu.
