Izilwandle nezilwandle

izilwandle nezilwandle

Impela sekukade ukhuluma noma ubona ngefayela le- izilwandle nezilwandle futhi ubudidekile lapho ubiza okuthile ulwandle nolunye ulwandle. Bahluke kanjani ngempela? Ukuhlukanisa kangcono zombili izindawo ezihluke ngokwendawo nangokwemvelo, sisebenzisa imiqondo yolwandle nolwandle. Zombili lezi zinqwaba zamanzi anosawoti okuyikhaya lezimbali, izilwane nezinye izinto ezithakazelisa umnotho wamazwe njengamadiphozithi esinawo Ipulatifomu yezwekazi.

Ngabe ufuna ukwazi ukuthi yini umehluko omkhulu phakathi kwezilwandle nolwandle? Kulesi sihloko sizokutshela ngokuningiliziwe.

Luyini ulwandle

Izilwandle

Into yokuqala okufanele siyazi ukwazi umehluko phakathi kwezilwandle nezilwandle ukwazi ukuthi yini into ngayinye ngokwehlukana. Ngale ndlela, singaqeda ukufunda le ndatshana futhi singabe sisangabaza ngakho. Izilwandle izandiso ezinkulu zamanzi anosawoti eziyingxenye ye-hydrosphere yomhlaba. Yilezo ezimboza ingxenye enkulu yomhlaba wonke. Kunezilwandle ezi-5 emhlabeni wonke ezihlukanisa amanzi nezwe lonke. Ake sibone ukuthi ziyini:

  • I-Atlantic Ocean. Yiyo ehlukanisa amazwekazi aseMelika, eYurophu nase-Afrika. Kubaluleke kakhulu kunakho konke ngoba, ukuthengisa, kuyindawo enkulu yokuthekelisa nokungenisa ngaphakathi ezweni. Ngaphezu kwalokho, inebhande lokuhambisa elisabalalisa kabusha ukushisa nokubanda kwezinqwaba zamanzi kusuka enkabazwe kuya esigodini esisenyakatho ngendlela elinganiselayo.
  • I-Pacific Ocean. Yiyo enokwandiswa okukhulu kunazo zonke izilwandle. Indawo yayo icishe ibe yizigidi ezingama-180 amakhilomitha skwele. Itholakala phakathi kwamazwekazi ase-Asia, eMelika nase-Oceania.
  • I-Indian Ocean. Iphakathi kwe-Afrika, i-Asia ne-Oceania futhi incane. Inendawo engamakhilomitha-skwele ayizigidi ezingama-74.
  • I-Antartic Ocean. Ihlala kuphela ku-14 million km2 futhi ihlanganisa yonke iNorth Pole.
  • I-Antartic Ocean. Ihlala cishe ezigidini ezingama-22 km2 futhi yiyo enwebela isigxobo esiseningizimu.

Incazelo yolwandle

umehluko phakathi kwamanzi

Manje sesiyazi ukuthi yiziphi izilwandle nokuthi yiziphi ezisemhlabeni. Endabeni yezilwandle kungenye into ngokuphelele. Izilwandle zingamanzi amakhulu anosawoti angaxhunyaniswa nolwandle noma angaxhumeki olwandle. Imvamisa kunjalo. Mincane kakhulu kunolwandle futhi futhi ayijulile. Azivamile ukuba nezindawo zemvelo futhi zisondele eMhlabeni. Kunamagagasi olwandle hhayi olwandle.

Singalwenza uhlu lwezilwandle ezinkulu emhlabeni jikelele yize, ngokungafani nolwandle, kukhona okuningi emhlabeni jikelele ngaphandle kwalolu hlu. Lapha sibeka kuphela ezibaluleke kakhulu:

  • ULwandle iMedithera. Yisandiso esikhulu kunazo zonke zangaphakathi kwezwekazi emhlabeni wonke. Kuphakathi kwe-Afrika, i-Asia neYurophu.
  • UMar Báltico. Ulwandle olusenyakatho-mpumalanga yeYurophu. Indawo yayo ingamakhilomitha-skwele ayizinkulungwane ezingama-420.
  • Ulwandle lwaseCaribbean. Impela ulizwile lolu lwandle izikhathi eziyinkulungwane njengendawo yokuphumula yokuphupha. Itholakala phakathi kweMelika Ephakathi neNingizimu Melika ngokunwetshwa kwamakhilomitha ayizigidi ezingama-2,7.
  • I-Caspian Sea. Ulwandle oluseNingizimu-mpumalanga Yurophu futhi lunendawo engamakhilomitha-skwele ayizinkulungwane ezingama-371.
  • ULwandle Olufile. Olunye lwezilwandle ozobe uzwile ngalo. Itholakala eMiddle East.
  • ULwandle Olumnyama. Idume ngombala wamanzi ayo, itholakala phakathi kweYurophu, i-Anatolia neCaucasus.
  • ULwandle Olubomvu. Futhi idume ngombala wayo. Itholakala phakathi kwe-Afrika ne-Asia.

Umehluko omkhulu phakathi kwezilwandle nezilwandle

Amanzi anosawoti

Manje njengoba sesazi izincazelo zezilwandle nezilwandle kanye nokuyinhloko emhlabeni jikelele, ake sibone ukuthi yini umehluko. Umehluko omkhulu phakathi kwezilwandle nezilwandle ubukhulu. Izilwandle zonke zincane kunezilwandle. Zivame ukuvalwa futhi zitholakala phakathi komhlaba nezilwandle. Izilwandle zingamanzi avulekile futhi ajule kakhulu.

Ngokungafani nezilwandle, izilwandle ziningi Imisinga ye-Ocean ezithinta ukujikeleza kwamanzi nesimo sezulu. Le misinga yolwandle ingakha izivunguvungu, okuyinto engeke yenzeke olwandle. Kunezilwandle ezithile ezingenaso isandiso esikhulu kakhulu, yingakho zithathwa njengamachibi amakhulu amanzi anosawoti. Isibonelo, eulwandle iCaspian, uLwandle Olufile kanye noLwandle i-Aral kuthathwa njengamachibi amakhulu amanzi anosawoti ngoba awamakhulu kakhulu.

Esinye isici ukushisa. Ngenxa yokuthi izilwandle zifinyelela ekujuleni okukhulu, ngokuvamile zifinyelela emazingeni okushisa aphansi. Izilwandle eziseduze nobuso bomhlaba zithola imisebe yelanga ethe xaxa futhi zinamazinga okushisa aphezulu kunezilwandle. Lokhu kuyehluka olwandle oluhlukile, ngakho-ke akunasimo. Isibonelo, amanzi oLwandle iMedithera afudumele kunalawo oLwandle Olufile.

Ngenkathi izilwandle zenziwa ugwadule futhi zincipha ngevolumu ngenxa yokufudumala kwembulunga yonke, izilwandle nezilwandle zikhuphuke ngevolumu ngenxa yokuncibilika komhlaba izimbotshana zeqhwa elisendaweni emincane.

Ngokuya ngezinhlobonhlobo zezinto eziphilayo, izilwandle zinenani elikhulu lezinto eziphilayo kunezilwandle. Lokhu kungenxa yokuthi bathola inani elikhulu lemisebe yelanga futhi banokujula okuncane. Ngakho-ke, yizindawo lapho kungabekwa khona izinhlobo eziningi zezinhlobo. Ezilwandle sithola inani elincane lezinhlobo, kepha ziyizinhlobo ezikwazi ukuzivumelanisa nezindawo ezijulile nokujula. Ngakho-ke, izinhlobo eziningi ezihlala ekujuleni azikwazi ukufudukela ezindaweni ezisogwini.

Yize kunokuhlukahlukana okuningi olwandle, kukhona nezinga eliphezulu lokufa, ngoba zichayeka kakhulu ekungcolisweni kwemvelo. Izilwandle, njengoba zikhudlwana futhi zikude nolwandle, bathambekele ekumelaneni kangcono nemithelela yemvelo yabantu.

Ngiyethemba ukuthi ngalolu lwazi ucacile ngomehluko phakathi kwezilwandle nezilwandle.
