Inta lagu jiro muddada xagaaga dabaysha waqooyiga waxaa is qarxiyaan kulul. Waxay soo hanfi kulaylka iyo heerkulka hawada ugu badnaan in mararka qaar ay gaari karaan +45 ° C. pampero keeni dhaxan (in -5 ° C) - duufaanka degaanka dabaysha xilliyo dhinaca koonfureed ee Antarctic in ay dhulka si ay u dhexgalaan. tacsida hawada Kuwani waxaa ka mid ah muddo gaaban. Gaar ah, waa in muddo ah uu baraf daboolay Rio de la Plata Basin. Waa maxay si la yaab leh? Laakiin kaliya qiyaasi in goobahaas, in la barbardhigo Russia, ku dhowaad marnaba qabow!

goobaha dabiiciga ah

Nature Area Rio de la Plata Basin la mid tahay steppe ah. Dhirta waa baahsan sanadka oo dhan, sida caadada qabow dheer in dhulka kajirin. Koonfurta waxaa laga heleyaa Prairie. In baa xagga woqooyi waa aagga dooxada swampy ee caalamka - Pantanal ah. Waa niyad jab a tectonic, meel tirada guud ee 150 sq. M. km iyo 50 m kor ku heerka badda. Marshland sameeyey by joogto ah mashaqeeyo Wabiyaal ugu weyn, kaas oo la dissected by Rio de la Plata Basin. Khariiradda hoose waxaad ka fekeri kartaa in si faahfaahsan muuqaalada goobaha juquraafi ahaaneed ee aagga.

On xuduudaha waqooyi-bari ee dooxada maraa degaanka dabiiciga ah ee kaymaha iyo dhul-dhireed. Waxaan u soo bandhigay, geedaha inta badan canbaha, noocyo kala duwan oo creepers, bamboos iyo ku xoortay geedihii (geed ugu badan ee gobolka - shaaha Paraguay). Dheeraad ah xagga koonfureed, daaqsinka kaynta waxaa gebi ahaanba bedelay badarka.

pampas

Gobolka wanaagsan ugu of Rio de la Plata Basin waxaa loo arkaa koonfur-bari. Meesha degan meelaha steppe - Pampas. Halkan, waxaa jira carradu cawl-brown bacrin ah. Dalka oo si firfircoon loo isticmaalaa dalagga ee calafka xoolaha iyo firileyda (sarreen) iyo galleyda. In deegaanka this waa daaqii ugu weyn.

Sababtoo ah ee qabashada aadanaha ee ku yaala goobahan ayaa dubato gabi ahaanba beddelay. Jiheysteen jira noocyo badan oo ka mid ah wakiilo ka ungulates, shimbiraha in markii hore deganaa goobta degaanka. deggan Animal ee gobolka ahaayeen jiirka oo kaliya.

Isticmaalka dhulalka

Rio de la Plata Basin qarniyo Jamciyadda furan, si Dhirta hooyo waxaa looga tegey. Of muuqaalkii si buuxda dib uqaabaynta.

guurka ka xagaaga qabowga meesha laga samri karo. waqtigaan qaaliga ah waxay fursad dhan sanadka inay dalka beeraha isticmaalaan. Inta badan si dabiici ah waraabiyo tixgeliyaa qaybta bari ee gobolka. Tan waxaa loo fududeeyey webiga Parana, Uruguay iyo addoommo fara badan ay. In galbeed ee Rio de la Plata Basin muddo gab. Inta ay qulqulka biyaha waa wax badan ka yar, iyo waxay yihiin xilliyeed.
