Izilwandle i-Atlantic nePacific, ulwandle lwamaNdiya kanye nolwase-Arctic, kanye nemizimba yamanzi yezwekazi, akha i-World Ocean. I-hydrosphere ibamba iqhaza elibalulekile ekwakheni isimo sezulu seplanethi. Ngaphansi kwethonya lamandla elanga, amanye amanzi olwandle ayahwamuka futhi awe njengemvula emazwenikazi. Ukusakazwa kwamanzi angaphezulu kuthobisa isimo sezulu sezwekazi futhi kuletha ukushisa noma amakhaza ezweni elikhulu. Amanzi olwandle aguqula ukushisa kwawo kancane, ngakho-ke ahlukile embusweni wokushisa womhlaba. Kumele kuqashelwe ukuthi izindawo zezulu zoLwandle Lomhlaba ziyefana nasemhlabeni.
Izindawo zesimo sezulu se-Atlantic Ocean
I-Atlantic Ocean yinde futhi kunezikhungo ezine zomkhathi ezineziqu zomoya ezahlukahlukene - ezifudumele nezibandayo - zakhiwa kuyo. Umbuso wamazinga okushisa wamanzi uthonywe ukushintshaniswa kwamanzi noLwandle iMedithera, izilwandle i-Antarctic kanye ne-Arctic Ocean. Zonke izingxenye zezulu zeplanethi zidlula e-Atlantic Ocean, ngakho-ke ezingxenyeni ezihlukene zolwandle kunezimo zezulu ezihluke ngokuphelele.
Izindawo zesimo sezulu soLwandlekazi lwaseNdiya
I-Indian Ocean isezindaweni ezine zezulu. Ingxenye esenyakatho yolwandle inesimo sezulu semvula, esakhiwa ngaphansi kwethonya lelizwekazi. Indawo efudumele eshisayo inezinga lokushisa eliphakeme lezinqwaba zomoya. Kwesinye isikhathi kuba neziphepho ezinemimoya enamandla, ngisho neziphepho ezishisayo. Inani elikhulu kakhulu lemvula liwela endaweni esenkabazwe. Kungaba namafu lapha, ikakhulukazi endaweni eseduze namanzi ase-Antarctic. Isimo sezulu esicacile futhi esivumayo senzeka esifundeni soLwandle i-Arabia.
Izindawo zesimo sezulu sePacific
Isimo sezulu sePacific sithonywa yisimo sezulu sezwekazi lase-Asia. Amandla elanga asatshalaliswa ngozoni. Ulwandle lutholakala cishe kuzo zonke izindawo zezulu, ngaphandle kwe-arctic. Ngokuya ngebhande, ezifundeni ezahlukahlukene kunokwehluka kwengcindezi yasemkhathini, nokuhamba komoya okuhlukile kuyasakazeka. Kunemimoya enamandla ebusika, naseningizimu futhi ayinamandla ehlobo. Isimo sezulu esizolile cishe njalo sikhona endaweni yezinkabazwe. Amazinga okushisa afudumele entshonalanga yolwandle iPacific, kupholile empumalanga.
Izindawo zesimo sezulu se-Arctic Ocean
Isimo sezulu salolu lwandle sathonywa indawo yaso esepolar emhlabeni. Ubuningi beqhwa njalo benza isimo sezulu sibe nzima. Ebusika, amandla elanga awahlinzekwa futhi amanzi awafudunyezwa. Ehlobo, kunosuku olude lwe-polar nenani elanele lemisebe yelanga. Izingxenye ezahlukahlukene zolwandle zithola imvula engafani. Isimo sezulu sithonywe ukushintshaniswa kwamanzi nezindawo zamanzi ezingomakhelwane, imisinga yomoya ye-Atlantic nePacific.
