Bangaki izilwandle emhlabeni? Funda Okwengeziwe!

Bangaki izilwandle emhlabeni? Lo mbuzo njalo kubangela isithakazelo esikhulu phakathi abafundi. Oceans ubhekwa igobolondo amanzi omhlaba, oluzungeze kwezwe isiqhingi. Ezinye izindawo amanzi ahlukaniswe umhlaba awalethe noma sendawo kwamanzi, is evamile ngokuthi iziLwandle. Ukusho ngokuthe ngqó ukuthi zingaki izilwandle emhlabeni nje akulula ngoba kukhona ngeengaba eziningi ezahlukene. Inombolo ephelele imizimba amanzi zingahluka: isibonelo, eduze ne-Aral, oLwandle Olufile, olwalubizwa iCaspian Sea LwaseGalile, owawubizwa ngokuthi ezilwandle, nakuba eqinisweni kufanele labizwa ngokuthi "namachibi". Futhi, kukhona eziningi amatheku, afanele ngaphezulu kumelwe babalwe phakathi olwandle.

Ukwahlukana zemizimba amanzi kungenzeka kwenziwe kuye ukuthi zikuphi. Yabadobi kolwandle, bayingxenye emikhulu, ngokuvamile ukuthi uthathe hhayi ku-akhawunti. Ngokwesibonelo, kukhona amasayithi yasekhaya eziyisikhombisa kuzo eMedithera. Kungenzeka ukubhukuda ngokukhululekile emkhunjini komunye, kodwa ngesikhathi esifanayo umkhumbi kuzohlala ngaphakathi lubhekisele oLwandle iMedithera.

Hlukanisa yangaphakathi, inter-Continental, abekelwe emaceleni, inter-isiqhingi izindawo. Kukhona ngezigaba ngokusho degree of usawoti kanye lokushisa lamanzi. Ngakho-ke, ukuze uphendule lo mbuzo ngokuthi maningi kangakanani izilwandle emhlabeni, ngeke isebenze ngokunembile.

Emhlabeni ku-akhawunti ulwandle ezinhlanu. Ngalinye lawo kubhekiselwa ulwandle evamile echaziwe. Ukuze Pacific Ocean baphathe enjalo izinto ezinkulu njengoba iBering, Yellow, Okhotsk, Japan, East China, South Sea China.

Atlantic kuhlanganisa aseBaltic, North, Sargasso, Marmara, Ionian, Aegean, Adriatic, nabanye abaningi. Kunezinhlobo ezingaba ngu-amathathu.

Indian Ocean, yakhiwa ingqikithi eziyisithupha kwezilwandle. I enkulu kulokho Red.

Arctic Ocean subjugates nantathu kwezilwandle. Phakathi kwabo, White, uBarents Sea, amaChukchi, Kara, East laseSiberia.

South, akubona bonke ososayensi bayaqaphela olwandle. Noma kunjalo, iqukethe izindawo amanzi ezisizungezile Antarctica.

Ukusho ukuthi bangakhi izilwandle emhlabeni, ungasebenzisa idatha yakamuva International Bureau Geographical. Namuhla kukhona amahlanu nane. Singeke kubhekwe kwezilwandle uma uya phakathi nezwe kanye gulfs.

Mediterranean

Ososayensi abaphambili kanye nezinhlangano zamazwe ngamazwe ukuze kuvikeleke imvelo bakholelwa ukuthi namuhla kolwandle dirtiest emhlabeni - iMedithera. Isiphetho esinjalo eMihlanganweni Yesigodi yamuva ethi umbiko wonyaka kanye UN benza. Minyaka yonke emanzini Mediterranean uwela ngenxa yezizathu ezihlukahlukene, cishe isigamu ayinkulungwane amathani imikhiqizo uwoyela. basengozini enkulu ngokukhethekile ukuba izimila nezilwane baningi imfucuza plastic, okuyinto umbeki indawo engasogwini.

Baltic

Notorious isici amanzi Inland nayo ekhungethe Black futhi Baltic kwezilwandle. Le ndawo eziyinkinga kakhulu ubhekwa eGulf of Finland we aseBaltic, okuyinto ugcwele ngamafutha achithekile. Ngenxa yokuthi oLwandle iBaltic uzungezwe nxazonke by emazweni athuthukile kwezomnotho (Sweden, Norway), bathulula amanzi kuwo isamba esikhulu ezimbonini. Ngo amanzi Black Sea egeleza ngokusebenzisa emfuleni futhi ikhanga ezinkulu-tonnage imfucuza womsebenzi kwezezimboni amazwe aseYurophu.

Marmara

I esiyingozi kakhulu ulwandle emhlabeni - Marmara. Libuye uye kulencane kakhulu. It ukhonza njengelungu umngcele phakathi eYurophu nase-Asia futhi isixhumanisi yokuxhuma iphakathi kolwandle Olumnyama futhi Aegean iziLwandle. Emakhulwini amaningi eminyaka adlule kwamiswa elalikhona, esagcina ogcwele amanzi e ungqimba lomhlaba. Ngakho kwavela Sea Marmara, kabani ukujula ifinyelela kwezinye izindawo, amamitha angaphezu kwelilodwa ayizinkulungwane ezingamakhulu amathathu.

Ingozi kule ndawo amanzi kukhona izinhlekelele eziningi zemvelo: tsunami kokuzamazama komhlaba. Emlandweni khona amanzi olwandle layiqhaqhazelisa izikhathi kunamasonto angaba amakhulu amathathu.

Ngo Ukwahlukaniswa imizimba amanzi emhlabeni futhi ube indlela lapho ulwandle izigaba esekelwe degree of usawoti emanzini. Oceans egcwele nosawoti ahlukahlukene, amshaya edwaleni ukufiphala ngaphambi. Inani ukudla okuqinile okuqukethwe, ziyoncibilika eyodwa kilogram yamanzi ngokuvamile ngokuthi usawoti. ezingeni layo lubonakaliswa ppm (kwetshumi iphesenti).

obomvu

Iningi okunosawoti kolwandle ezweni - the Dead and Red. Ngo ilitha lamanzi oLwandle Olubomvu iqukethe amagremu amane kasawoti. Ngenxa sokuyaluza njalo lamanzi phakathi laphakathi oLwandle Olubomvu has okufanayo lokushisa kanye usawoti ezingeni kunoma iyiphi ingxenye yalo.

Ekupheleni kwekhulu leminyaka elidlule, abacwaningi bathola ayimigodi zokuhlola ezingu equkethe "ukhukhamba" ashisayo. Amazinga isilinganiso okukukho degrees amane. Lokhu amanzi kuyasiza kakhulu impilo.

Dead

ULwandle Olufile idume ukwakheka eyingqayizivele amanzi nodaka. A neku- usawoti kudala high density ketshezi.
