Emathafeni - Iyini? Inchazelo nencazelo umehluko esuka emathafeni esishisayo

surface eMhlabeni libhekene ikakhulukazi emathafeni siyinqobile entabeni hhayi kuphela ezweni kodwa futhi ngaphansi kwamanzi.

Kuyini onokuthile?

Plain - a ezindaweni owendlalekile enkulukazi komhlaba lapho ukuphakama izigaba eduze buhluka 200 m, banayo eyehlelayo ababuthakathaka (hhayi ngaphezulu kuka-5 m). Isibonelo okunothando kakhulu lwase-Araba yakudala eWest laseSiberia Plain: kukhona i plain kakhulu ebusweni kokuphakama ushintsho okuyinto cishe imperceptible.

izici impumuzo

Njengoba siye wakuqonda definition ngenhla, ethafeni - sezwe flat nendawo cishe flat, ngaphandle Yokwenyuka okuphawulekayo ekwehleni, noma inamagquma, nge bushelelezi kushintshana uyanda futhi uya ngokuya incipha ebusweni.

emathafeni Flat ikakhulukazi umncane. Basuke etholakala eduze kolwandle nemifula emikhulu. emathafeni Okuningi ezivamile ginqo ezimazombezombe. Ngokwesibonelo, kwaba ukukhululeka East European (Russian) Plain libhekene amagquma kanyekanye amamitha angaphezu kuka-300 ukuphakama, futhi ayimigodi obude ngezansi kolwandle (ukucindezeleka iCaspian). Okunye emathafeni nabadumile ezweni - Amazon, Mississippi. Sinenkosi impumuzo efanayo.

Izici emathafeni

Isici esiphawula leli emathafeni iyona kungacacile, kuyabonakala sikukhombise umugqa, okungase kube iqonde noma inamagquma, njengoba kunqunywa ezindaweni ezithize impumuzo.

Abantu kusukela ezikhathini zasendulo luncanyelwa ukusungula nemizana emathafeni. Njengoba lezi zindawo abacebile amahlathi nenhlabathi evundile. Ngakho-ke, namuhla endaweni emathafeni zisekhona emaningi. Iningi amaminerali misela emathafeni.

Sikhishwe yokuthi ethafeni - izwe nge endaweni enkulu, futhi ngezinga elikhulu emikhubeni, basuke libhekene ezihlukahlukene izindawo zemvelo. Ngakho, e-East European Plain ukuhlangabezana zika amahlathi exubile kanye lezihlahla, emathafeni futhi ehlathini, asemaqeleni kanye lulwimi ehlane. Emathafeni Australia ethulwa emathafeni endawo eyihlanze kanye Amazon - Selva.

izici zezulu

Isimo sokukhululeka ngokwenkolo emathafeni - kuba umqondo ezibanzi, njengoba kunqunywa izici eziningi. Lokhu indawo, indawo zezulu, endaweni endaweni, ubude, ukusondela isihlobo olwandle. Ngokuvamile, isimo sezwe flat libhekene ushintsho ecacile zonyaka, sibonga ukuhamba zasezindaweni. Ngokuvamile ensimini yabo iyahlangabezana ngokuchichima emifuleni nasemachibini amaningi futhi nomthelela sezulu. Ezinye emathafeni kukhona sezulu eyomile, endaweni yabo omkhulu siqukethe ehlane okuqhubekayo (Turan ezisezansi, ithafa West Australian).

Emathafeni nezintaba: uyini umehluko phakathi kwawo

Ngokungafani Plains, izintaba ukumela izwe ngokucijile ekuphumeni ngaphezu kwamanzi eduze. Basuke izimpawu iyehla iyenyuka abalulekile eziphakeme kanye nesimo sendawo emaweni. Kodwa neziqinti sezwe flat ihlangabezane ezintabeni, PHAKATHI kwezintaba. Ziyakwazi ngokuthi agcwalise.

I emathafeni nezintaba - kuyinto ifomu wokukhululeka, umehluko ukuthi zisekelwe imvelaphi yabo. Iningi ezintabeni kwamiswa ngaphansi kwethonya izinqubo zomhlaba, zokwakheka ukunyakaza okwenzeka ekujuleni ungqimba lomhlaba. Ngakwelinye ihlangothi, emathafeni amanga ikakhulu amapulatifomu - izindawo nzile ungqimba lomhlaba, basuke uthonywe amandla sangaphandle Earth.

Umehluko phakathi izintaba izigodi, neziqongo ngaphandle ukubukeka imvelaphi, bungabonakala:

• ukuphakama esiphezulu (y emaThafeni isifinyelele 500 m, e ashisayo - ngenhla 8 km);
• endaweni (endaweni ezishisayo ku surface eMhlabeni kakhulu eliphansi kuya square plain);
• Amathuba ukuzamazama komhlaba (emathafeni kuba cishe zero);
• degree nezinga lokukhula kwengane;
• indlela yokusebenzisa umuntu.

I emathafeni ngobukhulu

Amazon ezisezansi, elise-Ningizimu Melika, iyona enkulu kunazo zonke emhlabeni, endaweni yayo - abangaba yizigidi ezingu-5.2 izinyawo square. km. Libhekene ongaphakeme ukwanda kwabantu. Libhekene sezulu kuhlale kushisa futhi kunomswakama, amahlathi emvula aminyene asezindaweni ezishisayo, usesikhundleni nsimu enkulu futhi zihlaselwe izilwane, izinyoni, izinambuzane nezilwane eziphila ezweni. Ezinye izinhlobo zayo eziningi zezilwane esifundeni sase-Amazon atholakala kwenye indawo.

Eastern Europe (Russian) Plain Itholakala Engxenyeni esempumalanga yeYurophu, indawo yezinye eziyizigidi ezingu-3.9 square metres. km. Iningi emathafeni endaweni itholakala e-Russia. It has a sezwe eziyize-flat. Nansi ingxenye enkulu yomsebenzi emadolobheni amakhulu, kanye bagxila ingxenye enkulu nomnotho wezwe zemvelo.

Central laseSiberia Plateau itholakala Eastern eSiberia. endaweni yayo - mayelana 3.5 izigidi ezingu sq. km. I engavamile yasethafeni - Noma alternation of izintaba kanye Amathafa ububanzi, kanye njalo Iqhwa, okuyinto ifinyelela 1.5 km ukujula. Climate - Continental, yezimila ubuswa amahlathi lezihlahla. Ithafa amumethe amaminerali ine olunzulu emfuleni umcengezi.
