Umncwebe weqhwa
Imincwebe yeqhwa iyiqhwa elinqumile elinomumo olinganayo ohlanganisa imingqobe ezingonithupha, a azingonithupha, namakleleba emincwebe. Imincwebe yeqhwa iyona ebanga imibukiso ehlukahlukene yomkhanyizo kumoyambulunga kanye nokwakheka kwamafu . [1]
Isibumbeko
hlela
Ngaphansi kwezinga lokushisa elizungezile noma ingcindezi efanayo, imizwayi yamanzi inomumo omise okwenhlamvukazi u'V'. Ngokuba amaChwe amabili weHwanzi aqalangana nechwe lesOhwe ngengoni enamazinga ayikhulu nesihlanu (105°).[2] Imincwebe yeqhwa eyisixabadiya somncwebe esizingonithupha, okusho ukuthi imizwayi yamanzi ijijeke ngokwezingqimba eziyizingoni eziyisithupha lapho ikhazeka.[1]
Ukukhula komncwebe lusilili okwenzeka kumoyambulunga obandayo noma owomisileyo kukhiqiza izilinganiso ezizingonithupha.[3] Imimo engathokala emincwebeni yeqhwa ihlanganisa imiqobe, usungulo, izibhebhe, namakleleba. Izifanelo ezivubile nazo ziyatholakala.[1] Izikhala ezincane ezinhlayiyeni zomoyambulunga zingabutha amanzi, zikhazeke, bese zakha imincwebe yeqhwa.[4][5]
