Nzizi dzeNorth America

Ine zita rekuti Rwizi Inozivikanwa nemafashama echisikigo emvura inoenderera inoyerera ichienda kune mamwe akafanana, anonzi makungwa: nzizi ndidzo dzinoyerera mumakungwa, idzo dzinozoita kuyerera kwemakungwa, nzvimbo dzemumvura dzinoumba 71% yenzvimbo dzepasi.

Nyika izere nenzizi uye nyika zhinji dzine akati wandei, kusanganisira idzo nyika dzisina nzira yekuenda kugungwa, idzo dzinonzi dzakakomberedzwa nyika.

Nzizi dzese dzine chimiro chechimiro chiri chavo. Kwayakabva rwizi rwuri muchikamu chinonzi nascent, inoenderera mberi ne Chokwadi, chinhambwe pakati peinobva muromo.

Mukosi yepamusoro unogona kuona nzvimbo yakatenuka zvakanyanya uye kufamba kwakakurumidza kwemvura, nekukwira kuri munzira yakatwasuka. Iwo epamusoro makosi ari, mune nyaya yekuoma, makoronga. Pakati nepazasi inosvika pamateru pane zvinyoro nyoro, iyo yekufambisa inoenderera uye kukoromoka kunova kwakatwasuka, kuchikurisa iyo Mupata. Iyo mugero ndiwo mwena unodarika nawo mvura, uye muromo ndiyo nzvimbo iyo rwizi runodururira mvura yayo.

Hodhi yehydrographic yenzizi inoita kuti zvive zvakakosha kutanga chibvumirano chekuona kuti rwizi rwupi uye ndedzipi mutero uye subafluents, mafashama emvura anopa kuyerera kurukova iye asiri iwo mukuru. Inowanzo tsanangurwa ne rwizi rukuru sekuyerera kukuru kwemvura, kana nehurefu hwayo hukuru kana nzvimbo yemadhiraini. Dzimwe nguva saizi nekuyerera kwenzizi zvakafanana neizvo zvemitero, kana mamiriro ekuyerera kwakakwirira anochinjwa zvinoenderana nenguva yegore. Ichi ndicho chikonzero zvakajairika kuti rwizi rumwe chete rudanwe nemazita mazhinji, kana mitero yakakosha kudomwa mazita nenzira dzakasiyana.

Iyo geography ye North America imusha kunhamba zhinji dzenzizi, zhinji dzadzo dzakabatana negungwa guru reMississippi-Missouri-Ohio, rinogara makiromita angangoita mazana matanhatu nemazana matanhatu. Iyi inharaunda yakazara mumakungwa, kunyanya glacial mavambo, ayo anogara yakawanda yeCanada. Chinyorwa chinotevera chinoratidza mimwe mienzaniso yenzizi muNorth America, nerondedzero pfupi yezvakakosha kwadzo:

1. Rwizi rweMississippi: Inoyambuka chikamu chepakati cheUnited States. Inomhanya pakati pekuchamhembe kweMinnesota neGulf yeMexico, iine kureba ingangoita zviuru zvina mazana mana emakiromita.
2. Rwizi rweMackenzie: Rwizi rurefu rweCanada, rwakatanga muGreat Slave Lake, muNorth West Territories. Inodira muGungwa reBeaufort, munzvimbo yeCanada.
3. St. Lawrence Rwizi: Iyo inoberekerwa muOntario, Canada, uye inodururira yakananga muAtlantic Ocean, mushure mekuyambuka inonzi San Lorenzo chikepe, chikuru kwazvo pasirese.
4. Rwizi rweColorado: Anenge makiromita 2 500 kureba. Kana ichipfuura neHurumende yeArizona, inogadzira chimwe chezvishamiso zvikuru zvezvisikwa, iyo inonzi 'Grand Canyon yeColorado'.
5. Missouri Rwizi: Rwizi runoyambuka Mapani Makuru eUnited States. Bheseni rayo rakagadzirirwa kudiridza, kudzora mafashama, uye magetsi emagetsi.
