Valley - Iyini? Elisho ukuthi "isigodi"

Ebalulekile ye bekhwela izintaba kuyinto esigodini. Lokhu kungolunye uhlobo olukhethekile nempumuzo, kuyinto umgodi side. Yena njalo kusukela nomthelela erosive kwamanzi, kanye ngenxa ezinye izici of isakhiwo Geological we koqweqwe.

Lisho ukuthini igama elithi "isigodi"

Zonke izinhlobo imishayo, imihosha, gullies kubangelwa abathathela amanzi notshwala kukhona esingesihle amafomu wezigodi. Ngenxa yalokho, inhlabathi siwasebenzise amanzi emfuleni nasogwini elisezansi kuphakama, okuyinto kuhlobene, bangase bafinyelele lonke uhlelo.

Relief kubo engazinzile futhi ziyahlukahluka kuye ngokuthi isiqondiso ukugeleza komfula. Intaba noma umfula esigodini - iyingxenye eziyinkimbinkimbi branched uhlelo namathafa. It inezigaba eziningana:

1. Slope - a ezindaweni ebusweni umkhawulo izinhlangothi esigodini. Ziyashiyana ukuphakama futhi, ngaphezu, angase abe eyehlelayo efanayo noma ehlukile (lapho omunye flat Strand, nomunye - a steeper).
2. Phansi (ibhokisi) - engxenyeni flat kanye ongaphakeme-lwamanga esigodini.
3. Outsole - yindawo lapho ijoyina phansi futhi nemithambeka.
4. Ingibe - umugqa ukuxhumana ebusweni kwemithambeka nezindawo ezizungezile.
5. Terrace. Lokhu amasayithi encane Kuqondaniswe ovundlile sise eziphakeme ezahlukene kusuka phansi esigodini.

izinhlobonhlobo izigodi

Izazi zesayensi yokwakheka komhlaba uhlukanise zonke izigodi entabeni futhi plain. Basuke kwakhiwa, ngokulandelana, igama endaweni ethile. Intaba Valley - a uhlobo impumuzo, elinesimo ukujula eside futhi engalingani emithambekeni emaweni.

I uyisicaba livuleka njengoba zikhula kancane evelele ukujula nge mnene emthambekeni bushelelezi, ububanzi kakhulu bakhiphe elezinga eliphansi. I element eyinhloko ububanzi imbobo phansi. Umlomo esigodini ngokuvamile kuba bay lapho umfula ugeleza khona.

Kuye indawo esigodini, futhi bechaza lokho okushiwo yile izwi e emithonjeni ehlukene. Kwezinye "Valley" - kuyinto ukucindezeleka side phakathi amagquma noma izintaba, nakwezinye - isikhala ngezansi sezwe ezizungezile, ngokuvamile owawuba ngomfula.

emfuleni esigodini

Kwakheka ngenxa yokuchayeka agelezayo. River Valley limelela elisezansi side umhlaba ebusweni elisukela umthombo emlonyeni. Ngokubukeka kwakhe zokuma kwendawo wazibonela kalula anqume yobudala nasesigabeni sokukhula kanye isakhiwo Geological kwendawo, crustal ukunyakaza elisemcengezini emfuleni, ufunde mayelana namabutho weathering nokunye okuningi.

River valley - uhlelo branched aqhelelene, kuphambene kakhulu ezungezile. Ukushintsha isiqondiso ukugeleza komfula ngokuvamile kuholela simo esishubile futhi kabusha izigodi, okuyinto ngezikhathi ngezicabha. izici zabo kwamanzi ahlukile phakathi kwezinye izinhlobo namathafa. Lokhu kusebenza izikhukhula somkhuhlane kanti izikhukhula imvula olubangelwa. Ochithekile zenzeka synchronously lonke iphrofayili esigodini.

Kwemithambeka izigodi emfuleni ngokuvamile embozwe ihlathi, futhi kwimfunda esetshenziselwa zotshani, izitshalo yezolimo, ezindaweni nephephile of ukuguguleka kulezi zindawo zitholakala nemizana.

Ngo esikhulu emfuleni kwimfunda kungadla insimu ububanzi kusukela km 15 kuya ku-30. Kuyinto ongaphakeme, odla izindwani ngonyaka, futhi omkhulu, okuyinto iya ngaphansi kwamanzi ngesikhathi izikhukhula esindayo kuphela.

Terrace elinendawo esigodini emfuleni - uhlobo Nicks ongakusho okuningi ngomlando emfuleni. Ngezinye isisekelo yabo overlie le Bedrock, kanye Kwamanzi camera emfuleni inhlabathi. On la masimu ungathola ezihlukahlukene inhlabathi endala emaxhaphozini namachibi, izinsalela likhona isikhathi eside izitshalo isikhathi nezilwane.

Kwemihosha nezigodi - lokho landscape entabeni. Basuke izimpawu emithambekeni emaweni futhi imisinga Rapids. River ekusakazeni enamandla unqamula idwala ukwakha kwemihosha futhi zigodi cishe emithambekeni emaweni lapho kungekho masimu.

Iphrofayela lezigodi osemusha izigaba lapho lo mfula ubizwa ngokushesha begijima Rapids. Ekugcineni, ngaphansi isenzo isikhala ukugeleza siqondile. Iphrofayela Smooth, okuyinto kuba esigodini - kuba kuwuphawu lokuvuthwa yayo.

Izindlela emfuleni izigodi

Ukwakheka izigodi kuthinta izinto eziningi. Phakathi kwabo, izinqubo zomhlaba ukuthi zilawule indlela yamadwala, ilele ukuguguleka kwenhlabathi kanye kwezulu yabo. Konke lokhu kunomthelela ukudalwa ezihlukahlukene emfuleni izigodi.

Gorge noma ezihosheni akhiwa ngokusebenzisa ukuguguleka ezijulile futhi basakaza ikakhulukazi ezindaweni entabeni. nemithambeka yabo emaweni sakhiwa edwaleni eliqinileko. Phansi ububanzi egcwele kuthatha khona emfuleni.

Zigodi izigodi emincane eyayibe akhiwa ezindaweni lapho imali zamatshe amandla ezahlukene. It ubhekwa umhosha ejulile eMfuleni Colorado (e-US) kuya kwangu-2 km ukujula.

I emathafeni uzamcolo wesiteshi emfuleni ithatha ingxenye encane nje kuphela. Ziyakwazi sici for emathafeni. Yonke esigodini masimu ungase ube ububanzi amakhilomitha angu-100 noma ngaphezulu. Kulezi zindawo ukuze kukhule izitshalo futhi ziklaba izinkomo. Shono imithombo eminingi encyclopedic, igama elithi "isigodi" sihunyushwa ngokuthi "wenzalo", "Ukuphila", "ukunothisa".
