Okukhulu-North American River

North American River bazongena esitelekeni ngobuhle bayo nangezithelo zayo ukwehluka. Ngamunye wabo has umlando walo lendabuko.

Umlando wemfundo

Lapho amanzi kaZamcolo ulishiyile izwe enkulu yeNyakatho Melika, noma kunalokho, ekupheleni the ice age lasendulo, endaweni ophakathi kwe-Atlantic, Arctic nePacific akha inombolo enkulu emifuleni nasemachibini amaningi. Leli chibi Lokudabuka glacial futhi zomhlaba. Ayesebuyela yeqhwa kwesokunxele endleleni ayimigodi zomhlaba zazo kancane kancane yagcwala amanzi.

Ngenxa yeqhwa, imifula kanye namachibi eNyakatho Melika kuyinto semali kwemithombo yamanzi, okuyinto ulunika ivolumu kuphela kancane i-Eurasia yayigcwele neseNingizimu. Ngobuningi babo yonke imifula North American namachibi basonta Atlantic elisemcengezini, kodwa inombolo ezanele wabo basonta imicengezi omunye izilwandle ezimbili. Amanzi la emachibini anosawoti omningi, kungukuthi etholakala nemifula.

Imifula eNyakatho neMelika, ebhekisela umcengezi Pacific, egeleza emathafeni kuze kube zeCordillera. Cordillera ukugeleza ngoba Atlantic umcengezi. Izintaba ukwehlukanisa amachibi ukubhukuda ezimbili futhi eyayiwuphawu kunawo wonke eNyakatho Melika. Ngakolunye uhlangothi, i- emathafeni omkhulu ahlukaniswe Atlantic nePacific umcengezi emifuleni.

Appalachian North American River

Empumalanga, lapho kukhona Appalachian Mountains emithambekeni yabo emathafeni ogelezayo ozalwa kulezi izintaba, imifula. Amazing Eqinisweni: yonke imifula emikhulu egeleza edabula isifunda Appalachian sentaba. Bamnquma ezintabeni ewumngcingo kodwa yimihosha ejulile. Labo abaqotho, lezi zinkulumo zisuselwa emithambekeni esentshonalanga futhi bayasilela ngqo Mississippi. Omunye Ohio, elinye igama - Tennessee. Okuphakelayo le mifula imvula kuphela ancibilike amanzi. Tennessee Polyhydramnios bese ugelezela kusukela ohlangothini lwesobunxele e-Ohio. Wona akhiwa lo mfula ubizwa yena, lapho kuhlangene emfuleni Holston emfuleni French Okubanzi River ewa amawa esentshonalanga Appalachia. Ngoba lina nsuku zonke, futhi iqhwa ancibilike ngisho lingandile, amandla la imifula akakwazi ngokuthi njalo. Sine amanzi Stocking nge namadamu akhiwe phakathi emifuleni kwezinye izindawo kwezinye amadamu. Ngenxa yalokho, phakathi kwemifula eziningi nemifula olunothile.

Empumalanga, umfula ugeleza khona phakathi eGulf of Mexico cishe zifana kuya thutheleka fula-Atlantic. Umhlangano omkhulu kunayo yonke futhi ebaluleke kakhulu kulezi emifuleni - Savannah, Potomac, Roanoke, uJames. Futhi isikhathi eside kunabo bonke kubo - Alabama River.

River enkonzweni abantu

Lezi emifuleni umsebenzi omuhle ensimini yamandla ezikhungweni zokuphehla eNyakatho neMelika. Somewhere yesikhombisa, nokuthi okungenani e-United States, okunikeza amandla amanzi egeleza aphume Appalachian Mountains.

Elikhulu eliseNyakatho Melika umfula kokunikeza ezwekazini akuyona amandla kuphela. Basaqhubeka ukusebenza okwenziwa amanzi awo isibalo esikhulu sezithunjwa imikhumbi, yamalahle, izikebhe nezinye ezokuthutha amanzi. Izikhangibavakashi amanzi ekhangayo izivakashi nezinye abagibeli ukuhamba nsuku zonke endleleni yakhe.

Lakes Olukhulu eNyakatho neMelika

Ngaphezu imifula, lezi zindawo yaziwa ngokuthanda lokuhlushwa eliphezulu amachibi. amachibi Great American abe uxhumano Atlantic Ocean. Michigan, ichibi elihle kakhulu ngokuthi Ontario, futhi Huron, Erie futhi emfushane kubo Lake Superior, okuyinto kufanele kubhekwe ukuba omkhulu angenasawoti echibini emhlabeni. Lezi amachibi omkhulu stepwise oxhumene iziteshi nemifula, emiseleni nemifudlana. Zonke ezihlanganiswe enhle emfuleni futhi echibini simiso izindlela. Igama St Lawrence umfula ogeleza aphume Lake Ontario enegama sonorous futhi uthululela ku Gulf, engivusa ngayo, njengasencwadini emfuleni njengoba St Lawrence waziwa. Kusukela Lakes Mikhulu ekuxhumaneni ne-Atlantic Ocean.

Phakathi eLake Erie neLake Ontario notshwala zaziwa Niagara River, Waterfall, ewa ukuphakama kwamamitha 50 ne ezintathu isiteshi elehlukile, ihlukaniswe emfuleni Imbuzi Island. Uthola izimpophoma ezintathu amahle, amakhulu kunawo wonke eNyakatho Melika. Lezi izimpophoma ziqoqwa lenqwaba izivakashi ezivela kuwo wonke umhlaba futhi unike amandla esakhelwe Hydropower izitshalo lapho.

Okukhulu-North American River

Ngokuhamba ezintabeni Cordilleras, emathafeni empumalanga, bendlale phezu Missouri River, okuyinto bevela kuzo zonke izinhlangothi zigcwala egeleza kuwo e amanzi amaningi. ENyakatho Melika, awusekho emfuleni Missouri. Yena feeds iminyaka ayizinkulungwane eziyishumi nambili abantu abaningi ku ogwini lwayo. Embhedeni salo inqwaba amadamu kanye izitshalo Hydropower. Akuyona into engavamile kuleli emfuleni nezikhukhula, nakuba izingxenye eyingozi kakhulu kwaqinisa. Missouri agelezela Mississippi. Njalo ingane owazi igama lakhe ngenxa yakhe isihlenga elintantayo Tom Sawyer nomngane wakhe Huckleberry uFinn. Lokhu emfuleni ezijulile futhi omunye Champions of ubude emifuleni emhlabeni. It ogeleza usuka enyakatho ngaseningizimu, uhlukanisa US zibe izingxenye ezimbili. Nakuba ingxenye yalezi hhayi bushelelezi, kodwa emfuleni ihlanganisa 10 uthi futhi umngcele ngoba abanye babo.

Khona-ke yonke imifula enyakatho Mackenzie wakhwela. It has amarekhodi ayo. Kuyinto isihloko emifuleni ende kunazo zonke eNyakatho nase-Canada. Wabuye eziningi inflow umnotho. Kuvele isibalo esingapheliyo imifula nemifudlana ukondla Queen of the North. Ingxenye esemqoka indlela Mackenzie odabula esishintshashintshayo circumpolar, esukela Omkhulu Nceku Lake. Nceku Lake ezijulile ngokungavamile. Kujulile kuka zakubo yayo - lonke emifuleni nasemachibini amaningi engxenyeni enkulu yeNyakatho Melika. Mackenzie River udlala indima ebalulekile emnothweni. On ke zithathwa futhi ore misela amaminerali avela ezindaweni ezisogwini Bear Lake. Kanye elinye Mackenzie River North - Yukon - kwenza ifaka isandla esibalulekile emnothweni, njengoba ukudoba. Thanda Mackenzie, Yukon izinyanga zazifihlwa ngaphansi eqhweni, it has Rapids abaningi busebenze, okwenza ukuthutha abantu nezimpahla, le mifula eNyakatho Melika esingesihle. Yukon ugobhozela Echibi Marsh futhi uthululela phakathi iBering Strait.
