Amachibi yizindawo zamanzi angenasawoti ezisemhlabeni. Kulokhu, ngeke sikhulume ngamachibi ajwayelekile noma ukwakheka kwawo, kepha kunalokho sizonikezela le ndatshana ku Amachibi amakhulu. Iqembu lamachibi amakhulu ama-5 enzeka phakathi kwemingcele ye-United States neCanada. Lawa machibi aphula amasu akho konke esikujwayele ukubona. Ngalesi sizathu, ngicabanga ukuthi kufanelekile ukunikela ngalokhu okuthunyelwe ukwazi lonke uqeqesho lwayo nokuthi imiphi imiphumela abanayo kuyo yonke imvelo ezungezile.
Ngabe ufuna ukwazi kabanzi ngamaGreat Lakes aseNyakatho Melika?
Izici ze-5 Great Lakes
Lawa machibi amakhulu awakhiwe njengosayizi ojwayelekile. Ososayensi bakuphethile lokho zakhiwa cishe eminyakeni eyi-13.000 edlule, ngemuva kokugcina Ice Age. Inani elikhulu leqhwa elivela ezinguzungeni zeqhwa elisentabeni lenza iziteshi zamanje ezanele zomhlaba ezaholela endaweni edangele kakhulu. Kulokhu, ngokwakha umcengezi lapho umhlaba uthambekele ekugcinweni kwamanzi, lokho esikwaziyo namuhla njengeGreat Lake kungakhiwa.
Phakathi kwamachibi ama-5 ahlanganisa indawo ephelele yamakhilomitha-skwele angama-244.160. Leli nani lamanzi lihambelana nama-21% wamanzi ahlanzekile aphelele emhlabeni. Le datha isenza sicabange ngokubaluleka kwala machibi hhayi kuphela ku-ecosystem yemvelo, kepha nakumuntu.
Yize siwabiza lawa machibi njengezinto ezihlukene, ezakhiwa ezwenikazi elilodwa hhayi kude kangako nomunye, zihlala zixhumene. Ngale ndlela, bakha umfudlana oqhubekayo wamanzi ahlanzekile okhuthaza ukwanda kwemvelo yemvelo, enezimila ezinhle nezilwane ezihambisanayo. Ngaphezu kwalokho, ezikhathini zasendulo kwaba negalelo elikhulu ekwakheni izifunda kanye nempucuko eyayisungulelwe lezi zixuku ezinkulu zamanzi ezwekazi.
Amagama alawa machibi yiHuron, iSuperior, i-Ontario, iMichigan ne-Erie. Konke kuphakathi kweCanada ne-United States. Zikulungele ukukhiqiza izindawo zemvelo ezingaba nokusimama nezomnotho ezithokozisayo nemisebenzi yezivakashi. Ngaphezu kwalokho, kubahambi nabavakashi, lawa maLwandle Omkhulu ayindlela enhle yokuthatha iholide elihle noma ukuphumula okufanelekile.
Ngokulandelayo sizochaza amachibi ngamunye nezici zawo eziyinhloko
Ichibi erie
Leli chibi lincane kunawo wonke ama-5. Kodwa-ke, ungajahi ngegama elincane, ngoba uma siliqhathanisa nelejwayelekile, lokhu kukhulu kakhulu. Iyona ethinteka kakhulu yimisebenzi yomuntu. Itholakala ezungeze ukuhlala emadolobheni kanye nemisebenzi yezolimo. Lesi senzo somuntu senza ukuthi ichibi lithole imithelela ethile yezemvelo esongela ukonakala kwalo.
Ayijulile njengamanye amaLwandle Amakhulu ngakho-ke ifudumala kakhulu ehlobo nasentwasahlobo. Ngokuphambene nalokho, ebusika singayithola iqandiswe ngokuphelele. Ngenxa yokuzala kwenhlabathi eseduze kwechibi, ezolimo zingasetshenziswa. Kodwa-ke, le misebenzi idala imithelela ethile emanzini nasemhlabathini, idala ukungcola okwehlisa isiziba echibini.
Isandiso sayo sihlanganisa izindawo njenge-Ohio, New York, Ontario, Indiana, nePennsylvania.
IChibi iHuron
Leli chibi lingesesithathu ngobukhulu uma liqhathaniswa namanye. Ixhunyaniswe neLake Michigan ngesikhala samanzi esibizwa ngeStrait of Mackinac. Yindawo enokuheha izivakashi eziningi ngoba inamabhishi anesihlabathi namatshe anobuso obukhulu.
Ukunwetshwa kwayo kufaka amadolobha afana neMichigan ne-Ontario. Umfula ophambili waleli chibi uMfula iSaginaw.
ILake Michigan
Sidlulela kwesibili ngobukhulu kulawa ma-5 Great Lakes. Itholakala e-United States futhi ayinayo umngcele neCanada. Ubukhulu bayo bungamakhilomitha angama-307 ubude nangaphezulu kogu lwamakhilomitha angaphezu kuka-1600. Itholakala endaweni enesimo sezulu esibanda kakhulu. Lokhu akukwenzi kube ngaphansi kokuheha izivakashi ebusika.
Ingxenye eseningizimu yiyona evakashelwa kakhulu njengoba ifudumele futhi iqukethe izindawo ezimbili ezinkulu zamadolobha amakhulu. ZiyiChicago neMilwaykee. Indawo yayo idlulela e-Illinois, eMichigan, e-Indiana naseWisconsin.
IChibi i-Ontario
Leli chibi ujule kunakho konke. Ngokuphelele ngosayizi kufana ne-Erie, incane, kepha ijule. Kubaluleke kakhulu ukuvakasha emadolobheni afana neToronto neHamilton. Ihlanganisa izingxenye ze-Ontario, New York, nePennsylvania. Imvelo yayo ivundile kakhulu kunokujwayelekile, ngakho-ke ezolimo nazo ziyaxhashazwa. Engxenyeni yeNew York kuphela akusetshenziswa ezolimo noma ukufudukela emadolobheni.
Ichibi eliphakeme
Igama laso selivele lisitshela ukuthi lichibi elikhulu kunawo wonke nelide kunawo wonke amaLwandle Omkhulu. Ichibi eliqukethe inani elikhulu kakhulu lamanzi angaphezulu namanzi ahlanzekile emhlabeni wonke. Inamanzi amaningi kakhulu ukuthi izokwazi ukugcwalisa amanye amachibi ama-4 futhi ishiye ngisho namanzi amaningi atholakalayo ukugcwalisa amachibi amaningi. Kukwelinye izinga maqondana nalezi ezedlule. Kubanda kakhulu kunakho konke futhi kufaka amadolobha aseMichigan, Minnesota, Ontario naseWisconsin.
Njengoba ingeyesimo sezulu esibanda kangaka, ayihlalwa kakhulu. Ezindaweni ezizungezile sithola inqwaba yezihlahla ezinabantu abaningi, ezinabantu abambalwa futhi ezitshaliwe. Inhlabathi ayivundile kakhulu, ngakho-ke ayizilungele ezolimo.
Ezinye izifiso zamaLwandle Amakhulu
- EMachibini Amakhulu singakwazi thola izinhlobo ezingaphezu kuka-3.500 XNUMX zezitshalo nezilwane.
- ILake Superior inamandla amakhulu kunolwandle kunechibi.
- Kuneziqhingi ezingaphezu kwezi-30.000 ezisabalele emachibini ama-5, kepha hhayi encane kangangoba ayinakuhlalwa.
- Kuwo wonke umlando, kube nokuphahlazeka okuningi kwemikhumbi emachibini.
- Ubuso bukhulu kangangokuba bayakwazi ukudala izivunguvungu ezinamandla njengalezo zolwandle.
Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi ngamachibi amakhulu omhlaba.
