Xa sithetha ngechibi, sibhekisa kumanzi asisigxina afakwe kuxinzelelo olukhoyo ebaleni. Oluxinzelelo lunokwenziwa kwiimpazamo zejoloji kwaye Orogenesis. Zingabangelwa kukuqokelelwa kwe-glace gliten okanye i-avalanche yekhephu. Namhlanje sikuzisa uluhlu lwe amachibi amakhulu emhlabeni.
Siza kukuxelela ukuba ngawaphi amachibi amakhulu emhlabeni kwaye zeziphi iimpawu zawo eziphambili.
Ulwandle lweCaspian
Idike linokuqulatha amanzi amatsha kunye netyuwa. Ukwenziwa kohlobo ngalunye lwedike yinto emisela iimpawu kunye nohlobo lwamanzi oluza kubanjwa. Kule meko siza kuthetha ngoLwandle lweCaspian.

UMthetho oYilwayo ngobunzulu be-371.000 km2 kunye nobunzulu obuphakathi kweemitha ezili-170.
Igama loLwandle lweCaspian kungenxa yeCaspian. Ligama ledolophu yakudala eyayiphuhliswe emazantsi-ntshona echibi. Inentyatyambo eninzi kunye nezilwanyana kwaye ityebile kwii-sturgeon kunye namatywina. Ngelishwa, lulwandle olunemicimbi emininzi phakathi kwamazwe kuba ikwanemithombo yezimbiwa efana neoyile kunye negesi yendalo kwaye iphantsi kwengxaki eziqhubekayo. Ukuloba kunye namanzi aphesheya nawo abangela iingxaki, kuba ukusuka kwindawo ethile, akwaziwa ukuba ngubani onoxanduva lolawulo lwayo.
Inxalenye esemantla echibini iqina ngaphezulu kwiinyanga ezibandayo kwaye isetyenziselwa ukwenza ukubaleka kwe-ski. Unokuthi ngumkhenkce onetyiwa ongavumelekanga kakhulu kuyo nayiphi na intaba.
IChibi elingaphezulu
Inye ye5 Amachibi amakhulu eMntla Melika. Ime phakathi kwe-United States ne-Canada. Inommandla we-82.000 km2, lelona chibi likhulu lamanzi angenawo amanzi ehlabathini. Unalo mthamo wamanzi kuba kukho ngaphezulu kwemilambo engama-200 engena kuwo kwaye iyawondla ngokuqhubekayo.
Igama leLake Superior kungenxa yokuba amaNgesi ayibeka ngexesha lokuhlola ngo-1760. Yayilichibi elinelona nani likhulu kunye nenani lamanzi ababelifumene ebomini babo. Iqondo lobushushu lamanzi ngama-7 degrees kunyaka wonke. Ubusika kweli chibi akubandi kakhulu kwaye ihlobo liyaphola.
ILake Victoria

Umlambo waseKagera ngowona mjelo mkhulu uxhasa ngokuqhubekayo. Ubunzulu bechibi ziimitha ezingama-82 kuba ibekwe ngaphezulu koxinzelelo oluncinci. Ubunzulu obumndilili ziimitha ezingama-40 ngelixa i-82m bubona bukhulu bufunyenwe kwindawo ephambili yoxinzelelo.
Kukho imicimbi yendalo esingqongileyo ebangela ukuphela kweentlobo ezininzi zeentlanzi ngenxa yokuloba kakhulu. IHyacinth yamanzi yenye yezityalo ezihlasela eli chibi kwaye ziyenza ibe yityhefu. Esinye isizathu sokuba umgangatho wamanzi ewohloke kungenxa yokukhutshwa kwenkunkuma yasekhaya kunye neyamashishini.
IChibi laseHuron
Elinye lamachibi amakhulu eMntla Melika. Yeyona yesibini ngobukhulu kumachibi ama-5 aphakathi kwe-United States ne-Canada. Eli chibi linemida yeOntario neMichigan entshona, elinye lamaLwandle amaGreat. Ubunzulu bomndilili wayo ziimitha ezingama-59 kwaye ubuninzi ziimitha ezingama-229.

El ichibi leBaikal Ingenye yezona zikhulu zikhulu eSiberia. Waziwa ngokuba ngu-no, bre de Ojo azul. Ubude bayo ngama-5539 km kwaye lelinye lamachibi acacileyo kwihlabathi. Inomdaka omncinci kakhulu. Yachongwa njengeNdawo yeLifa leMveli yeHlabathi yi-UNESCO ngo-1996 kwaye inendawo eyi-21.494 yeekhilomitha. Ubunzulu obumndilili ziimitha ezingama-744 kwaye ubuninzi ziimitha ezili-1642. Njengoko ubona, bunzulu ngaphezu koLwandle lweCaspian.
Lelona chibi likhulu lamanzi acocekileyo eAsia kwaye lelinye lawona manzi anzulu kwihlabathi. Ineentlobo ezingaphezu kwe-233 ze-algae kunye neentlobo ezingaphezu kwama-852 zezilwanyana nezityalo.

Inezinto ezahlukeneyo zentlanzi kunye nezinye iintlobo zezityalo nezilwanyana ezidala imisebenzi emininzi efikelela kuma-45.000. Ime phakathi kwamazwe aseTanzania, iBurundi, iDemocratic Republic of the Congo neZambia.
Ndiyathemba ukuba ngolu lwazi ungafunda ngakumbi malunga namachibi amakhulu emhlabeni. Njengoko ubona, kukho amachibi anobunzulu kunye nomphezulu ofana nolwandle lokwenyani. Ndiyathemba ukuba unokuba nethamsanqa ngokwaneleyo ukuba ungaya kwezinye zeendawo ezintle nezimangalisayo.
