Yintoni imilambo umahluko nelezihlambo entabeni? iimpawu zothelekiso

River - lo mthombo wamanzi okusela eluntwini. ukubaluleka kwabo ayikwazi phantsi. Imilambo njengokuba imijelo yamanzi, akhiwe kwi kwintsimi lonke ilizwe emhlabeni.

Ahla imijelo iqundaniswe ubungakanani (amancinci, aphakathi, ezinkulu) kunye nokubekwa ngesimo. Leyo elimi apho kwemali umlambo, yonke imilambo yehlabathi zohlulwa ngokwendidi ezahlukeneyo ezimbini amanzi. Yintoni ezahlukeneyo ukusuka iliwa umlambo caba, inokubuyiselwa eziqondwa ingcaciso enikwe kweli nqaku. Ezinye imilambo zi ludidi lwe mixed: bakwazi ukuqhubeka, yaye omnye uhlobo ezisemagqagaleni, ngokwahlukeneyo.

Rivers Types: definition

Gorilla umlambo - umzimba amanzi aye uzolile, sithantamise wavela, idake intili ebanzi kwaye ujikeleze ngendlela yeArabha, okanye tyaba sendawo.

Mountain River - njengesihlambo esikhukulayo kwintlambo elimxinwa yaye zinzulu, ukuba sele ukuhamba ngokukhawuleza kwaye anzima, udlula ngaphakathi isiqabu intaba.

Inkcazelo echanileyo ngakumbi oko okungenanto komlambo kunye entabeni, yintoni umahluko phakathi kwabo zinokufundwa ngezantsi.

umthombo

Umthombo nelezihlambo imifula ngokuqhelekileyo amachibi, amadama, imithombo yamanzi aphantsi komhlaba; intaba - imvelaphi yayo ezintabeni, kwiindawo ikhephu okanye ice apho.

imilambo

imilambo Power nelezihlambo ikakhulu ugalelwe, kunye ukugqithisela ngekhephu. Zalisa kuzo iqala entwasahlobo. Ithuba ukusuka kwiintsuku ezili-15 ukuya kwinyanga 1. Emva kokuba izikhukula, amathontsi amanzi, ufikelela umgangatho wayo uphantsi, ebizwa amaxesha ukuwutha kwamanzi. Ukuthetha ngomahluko phakathi mathafa omlambo entabeni, oku kukuthi iziziba ngamanye amaxesha kwabancinane, ngoku kancinane esikhuthazayo yelizwe, kufuneka ipropati ukuba yome ehlotyeni. Kodwa ekwindla, ngexesha konogumbe, ukuba abuyele nolawulo lwangaphambili. Xa imilambo entabeni yokuziphatha eyahlukileyo ngokupheleleyo. Zinelungelo flow rhoqo, kuze owomileyo, ubusika ukuze ngumkhenkce ngokupheleleyo. Bona batya phezu komlambo ikakhulu ngenxa kwezulu (imvula). Eli nani liphezulu kuba ehlotyeni, kuba sohlala kweli xesha imijelo kwentaba ayikhukulise iibhanki. Inqanaba lamanzi ebusika yehliswe kangangoko kunokwenzeka, kwaye zokuzuza ikharektha ezolileyo.

lokubanda kwamanzi

imilambo nelezihlambo kunye ntaba (umahluko phakathi kwabo akuxhomekekanga nje kuphela iikhrayitheriya ngasentla) kufuneka kumanqanaba ahlukeneyo lobushushu amanzi. Yena njengamanzi kufuphi encotsheni, uhlala phantsi, amanzi ngenkankulu warm ngexesha lasemini. Emilanjeni entabeni ephezulu, xa ezise zintabeni, lobushushu ithotywe + 2 ° C. imijelo yamanzi egqiba nelezihlambo kuyahlukana kulo nyaka, ngokuxhomekeke kuhlobo kwemozulu. Amaninzi, umlambo onjalo ebusika kakhulu obubandayo, maxa wambi yovalo kumphezulu, ngezigaba ezithathu: ukuqanda, ice kunye kwesidumbu. Ehlotyeni, ubushushu kuyo liphuma kakhulu.

river Valley

Ukuqhubeka unikezele ulwazi umahluko phakathi mathafa omlambo entabeni, kuyimfuneko ukuba acacise ukuba uhlobo ezantsi dama, aqukuqelayo evela phezulu, i kuphela impembelelo sezwe. amanzi abe ezantsi ngokunzulu, Etsolweni lengxondorha, obungalinganiyo, kunye nonxweme phantse lonke luphawulwa ngemvelo enamatye kunye nokwehla exandekeni. Zithethwa emazantsi omlambo entabeni - V-ezimilise, kwiimeko ezininzi. Le track efanayo rhoqo emxinwa, akanalo ebanzi lonke ubude bayo. Eli xesha zixhomekeke Velocity kwemali kunye engile utyekelo ichibi. Gorilla imilambo izizathu ububanzi neentlambo zayo, ezinzulwini curl kunye namathambeka ephantsi. Umandlalo loqukuqelo esinjalo kudla indalo jiko, nasezantsi - uneentlenga (onodongwe ngamanye amaxesha Inokwenzeka kunye namabala nesanti). Amaninzi iliwa inxalenye ephantsi entilini awufumaneki ukuba umlambo kumathafa ibe nemiqobo okanye ukufuna, zazimele rocks uyisanti. ijikajike ezinkulu kuthiwa ijikajike (kugobeka). Eyona nto eqhelekileyo le ntaba nezihlambo imilambo: babe imigubasi yomnyango, nto leyo kakhulu ukuphembelela bomyinge wamanzi. Bangakwazi abunjwe xa amanzi ukwakweli unelitye eliqine (nasentshonalanga, kumaqonga).

flow Velocity

Into ezincinane ebalulekileyo umbuzo umahluko phakathi mathafa omlambo entabeni, ziya kuba nohlobo kwemali. Amadama kusengenziwa eziphezulu babe flow fast, avareji kwamanzi ukufikelela ixabiso-6 m / s. Kwiindawo kufutshane uwela, ukuhanjiswa kwamanzi nga phambili kwandisa. Izinga sokuqukuqela umlambo intaba kuxhomekeke kwinqanaba ukuthambekela. Ukuba uphakamile lo ekujikeni, i ngokukhawuleza ukuphuma kwamanzi. Gorilla imifula kokushenxa ezolileyo. ke imithombo zawo zibekwe kwi indawo iphakeme kancinane, ngoko kwithambeka yabo.

Ukusetyenziswa kwezoqoqosho imilambo

imilambo nelezihlambo nemisinga intaba ezingachazwanga ngokulinganayo kusetyenziswa kwinkalo yezoqoqosho. Kule nkalo, i-yokuqala ukhetho Umbambisi kakhulu. Kuqala kwinto zonke, kwiimeko ezininzi ukuba iinqanawa, ngelixa imilambo entabeni ingxubevange phantse akunakwenzeka (ngaphandle kokuba kuqwalaselwa kuphela imidlalo eyingozi). imilambo nelezihlambo babe ipropati wokusungula ogudle zivuleke intlanganisela yolwandle okanye olwandle. Yinto eyaziwayo ukuba umhlaba kulo mmandla echumayo. Xa amanzi ayo ichthyofauna ngaphezu emilanjeni entabeni. Kweli nqanaba, oko iba nefuthe elikhulu lobushushu amanzi kunye isantya sokuqukuqela. Kwaye ngokwemiqathango uKhenketho noLonwabo, imilambo nelezihlambo ziyaphuhliswa ngakumbi.
