I- imifula Yimifudlana yamanzi amasha egeleza emazwenikazi, isuka ezindaweni eziphakeme kakhulu iye ezingxenyeni ezingezansi. Ngale ndlela, ukukhululeka kuyisici esinquma kakhulu izici zomfula, isici esikhona kokubili emifudlaneni emincane kakhulu emifuleni enokugeleza okuphezulu kakhulu emhlabeni.
I- ukugeleza komfula akuvamile ukuba njalo, futhi zonke zivamise ukugelezela olwandle, amachibi kwesinye isikhathi nolwandle uqobo, ngokusebenzisa imilambo noma ezinye izakhiwo ze-hydrographic ezenza ukuthi kwandiswe kakhulu isikhala lapho amanzi edlula khona: ngokusebenzisa lezi zinhlaka zamanzi ezingacishe zivalwe imvelo ethile yasemanzini yenziwe, ngenxa yezinqubo eziyinkimbinkimbi zomzimba nezemvelo ezenziwa lapho .
Kunezikhathi, ngakolunye uhlangothi, lapho umfula ugelezela komunye umfula kuphela, okuyikho okwenzeka kulokho okubizwa ngokuthi imifula engenela. Iphuzu lapho ukwakheka kwe-hydrographic kwehlukanisa (noma ukujoyina) kubizwa ngokuthi yi-confluence, futhi ukugeleza komfula othola imithamo kuhlala kungaphansi kwalowo owandulelayo.
Ingakusebenzela:
- Imifula yaseNyakatho Melika
- Imifula YaseMelika Ephakathi
I- umfula omkhulu kunayo yonke emhlabeni, I-Amazon etholakala eNingizimu Melika, inamakhilomitha ayizi-6 800 futhi umzila wayo uwele imifula engaphezu kwengu-1 000, eminye imifula engama-25 enamakhilomitha angaphezu kwenkulungwane ngobude. Ubukhulu boMfula i-Amazon buyaphawuleka, buhlanganisa ngokwawo ama-40% aseNingizimu Melika.
NjengaseNyakatho Melika, ku i-South America Kukhona uchungechunge lwezintaba oludabula eNtshonalanga yezwekazi ukusuka eNyakatho kuye eningizimu, iketanga laseAndes. ENingizimu Melika, leli chungechunge libizwa ngokuthi yi-Andes Mountains, futhi libalulekile ngezinhloso ze- ukwakheka kwe-hydrographic akhiwa kulelo zwekazi.
I- i-biome yezwekazi eliseningizimu ikakhulukazi eshisayo, ikakhulukazi a ihlathi biome kunomswakama: umcengezi oshiwo ngenhla woMfula i-Amazon uqhuba kakhulu uhambo lwawo kuleso sifunda. I- amanye ama-biomes akhiwe azungeze imifula yaseNingizimu Melika afaka amahlathi ahlala eluhlaza asezindaweni ezishisayo, amahlathi ashisayo anezinkathi zonyaka, ama-savanna asezindaweni ezishisayo akhiwa ngamathafa emvelo, noma izinkuni intaba emithambekeni ye-Andes.
Uhlu olulandelayo lufaka ezinye amagama emifula eNingizimu Melika, ngencazelo emfushane ngezinye zazo.
- Umfula i-Amazon: Umthombo wayo wenzeka ePeru, lapho kuhlangana khona imifula iMarañón ne-Ucayali. Ubukhulu baso benziwa bube sobala ngokubona ukuthi ngumfula omude kunayo yonke, onamandla kakhulu, obanzi kakhulu, ojule kakhulu nomcengezi omude kunayo yonke emhlabeni.
- Umfula i-Orinoco: Ungumfula wesithathu ngobukhulu emhlabeni. Kwenzeka kuzikhukhula ezinkulu, ngenxa yezimvula ezinkulu ezishisayo ezikhiqiza izikhukhula ezinkulu. Ithola cishe imifula engama-200 enemifudlana engaphezu kuka-500.
- Umfula iParana: Umfula oyingxenye yesizinda esikhulu seLa Plata. Ihlukaniswa njengomfula ogelezayo, ngoba ithwala futhi idonsele indle ekugelezeni kwayo.
- Umfula iParaguay: Wazalelwa esifundazweni saseBrazil saseMato Grosso, futhi usebenza njengomkhawulo ezimweni ezintathu zamazwe; phakathi kweBrazil neBolivia, phakathi kweBrazil neParaguay, naphakathi kweParaguay ne-Argentina. Ungumthambo omkhulu womfula iParaguay.
- Umfula iSiliva: Umfula onomfula, owakhiwa e-Argentina nase-Uruguay ngokwakhiwa kwemifula iParaná ne-Uruguay. Inokukhethekile kokuba ngumfula obanzi kunayo yonke emhlabeni.
