Cordillera - buuraha, noocyo kala duwan oo badan oo xaaladaha dabiiciga ah. Tiro ka mid ah muuqaalada, waxay waxaa lagu gartaa, iyo waxa uu qeexayaa in ay la aqonsado hababka kale ee buurta ee caalamka ka mid ah.

sifooyinka guud ee Cordilleras ah

Aaway buuraha reer Cordillera ah? Haboonba ay kordhiso in submeridional jihada a. shan suunka orotektonicheskih ee da'doodu kala duwan tahay gudahood sameeyay buuraha kuwan. Cordilleras ka kooban yihiin tiro badan oo buuraleyda ah (2,5-3 kun. Mitir ama in ka badan heerka badda). Waxay leeyihiin volcanism firfircoon oo seismicity sare. dhererkiisu weyn buuraha waqooyi ilaa koonfur waa keentay in joogitaanka hannaanka ah spectra of zones altitudinal. Cordillera - buuraha, la aasaasay at isgoyska u dhexeeya taarikada lithospheric. Oo soohdintu waxay u dhaxeeya dhow yahay ku beegan tahay line ee xeebta.

Halabuurka The of Cordilleras ah

Qaybta saddexaad ee degaanka ee qaaradda oo dhan degan nidaamka buurta laab-block a. Waxay leedahay width a of 800-1600 km. In ay ka kooban waxaa ka mid ah plateaus buurta, hogag intermountain, Oo tiixtiix iyo plateaus Kobenhagen iyo buuraha. lahayo ku Young, hawl Kobenhagen, waxaan soo maray denudation ah Cordillera, kaas oo goostay ay tahay muuqashada joogo oo u qarineysaan badan oo dhismeedka dhulka ee in ka hor muuqday. nidaamka buur aad u Nuurre Aw labadaba codbixineed oo jihada gaadhya.

Faahfaahin dheeraad ah oo ku saabsan qaab dhismeedka Cordilleras ah

Qaab dhismeedka dusha ku dhufo oo ka mid ah qaaradda, halkaas oo buuraha reer Cordillera ah. Waxay mashquulin qaybta galbeed, bari - buuraha hoose iyo bannaanka u baaxad weyn. qaybta galbeed waxa uu ku yaalaa at sare ah oo ku saabsan 1,700 oo mitir, iyo bari - 200-300 mitir 720 mitir waa height celceliska qaaradda ..

Cordillera - buuraha, isagoo in ay ka kooban dhowr ah oo labada cirif buurta in guud ahaan la kordhiyo jihada ka WoqooyiGalbeed kuna socota KoonfurBari ah. Laga soo bilaabo magaalada Mackenzie, XP. Brooks, bari ee Mountains Rocky ka kooban ARC. suunka go'aysa soo sameeyey banka gudaha iyo banka ku yaal galbeedka oo safafka kuwan. 1-2 kun. Mitir ee ay height.

Badanaa waxay talantaalli hogag, Oo tiixtiix iyo kantiinada xajmi oo fidsan.

buurta ugu sareeya

Cordillera ee qaybta galbeed ee nidaamka calaamadeeyay tiixtiix ugu sareeya. Tani Aleutian Range, Ridge Aleutian Islands, Alaska Range. Last gaadho height ah 6193 mitir. Waxaa McKinley ku cad sawirka kor ku xusan waa buurta ugu sareeya. Cordillera - nidaamka, oo ay ku jiraan qaybta galbeed iyo Buuraha Cascade ah, Mountains Coast ee Kanada, Sierra Madre Occidental iyo Nevada Sierra ah, iyo sidoo kale Transverse uurada Sierra halkan ka ku yaalla volcano Orizaba ah (5,700 mitir), iyo kuwa kale.

Si galbeed, sarajooggiisuna waa la dhimay iyaga by. Cordillera - buuraha, oo si habsami gelin guriga ee qaaradda. Her qaadan ee xagga galbeed jira ama talgaley (California, Puget Sound, Cook) ama bannaanka ah (Valley Central, River Willamette Valley.). qaarada xeebta Tani sameeyay tiixtiix St. Elias, Chugachskim, Kenai, Island Ridge Kanada, iyo Coast Maraykanka Range. Cordillera silsilad koonfureed ee dhulka sare ee bifurcate Mexico. East diiday mid ka mid ah, la xirrira gasiiradaha xiray West iyo tiixtiix gujis, ka dibna la geeyo geedka kokaha Venezuela. Qeybtii labaad ayaa la jiido dhex Panama iyo Teuantepeksky luquntooda in Colombia geedka kokaha.

Iyada oo waxa kala duwan dhul buuraha?

Waxaa la xidhiidha meelaha da'da dalka kala duwan, iyo sidoo kale taariikhda horumarka. Ma aha mar baa la sameeyey ay hadda u habeysan waynaha. buuraha Cordillera ay hadda u habeysan kacay iyada oo loo marayo habka kala duwan, dhacaan waqtiyo kala duwan ee qaaradda.

Waayo, Laurentian Upland, calaamadeeyay dhismeedka dhulka ugu qadiimiga ah, dhul dheellitir dusha oo ah mid caan, formation of taas oo bilaabay horraantii Paleozoic ah. dusha dhireedku sababay iska caabin kala duwan oo casri ah kacsantahay dhagaxyadii denudation iyo dhaqdhaqaaqa tectonic sinnayn. Qaadista qaybta bartamaha ee dhulka keentay in cover a of glaciation Quaternary, sababtoo ah taas oo la aasaasay godadka casriga Hudson Bay. Intaas waxaa sii dheer, sarkhaansan ay halkaas joogay raasamaal ah oo biyo ah iyo faar moraine glacial in la aasaasay nooca gargaarka (moraine buur ah).

Great iyo Valley Central nooca kaydka yihiin. Under saameynta ay geedi socodka denudation meelo kala duwan, waxay ku xiran tahay sifooyinka of dhacdo dhagaxyada kala duwan, Oo tiixtiix Cuesta sameeyay (Great Lakes), casilay banka (Babacyada Great), Midlands iyo dhulka nabaad (Ouachita, Ozark).

dhul aad u adag oo Cordilleras waxay isku. riixo Band of qolof ah waa gudbay by badan unu, laga bilaabo dabaqa Badda iyo dhamaado on dhulka. Weli ma buuxiso geedi socodka orogenic. Tani waa caddaynta ku buureedyada (tusaale ahaan, Popocatepetl iyo Orizaba), iyo sidoo kale dhulgariir xoogan oo halkan dhacaan waqti ka waqti.

macdan

Sida aad ogtahay, wax badan oo ka mid ah macdanaha kala duwan laga heli karaa meel kasta oo ay jiraan buuraha. Cordillera - waa laga reebo lahayn. Waxaa jira kaydka weyn ee biraha non-ferrous iyo ferrous. Non-macdan saliid lagu aqoonsan karo, oo ku yaalla maddiibadihii intermountain. Kaydka ee lignite yihiin ee gobolka Rocky Mountain (hogag ay gudaha).

cimilada

Caan ku cimilada ay sii wadi doonto description buuraha. Cordillera u guurayso tacsida hawada badda. Taas darteed, saameynta ay badda waxa si wayn u wiiqay dhinaca bariga. Tani feature cimilada ee Cordillera waxaa muuqata in ay ciidda iyo daaqsinka, horumarinta glaciation casriga ah, goobaha altitudinal. Jiida xagga woqooyi inay safafka buurta koonfurta go'aamisa kala duwan heerkulka ee xagaaga iyo jiilaalka. Xilliga jiilaalka waxa ay u dhaxeysa -24 ° C (ee gobolka Alaska) si +24 ° C (Mexico, koonfureed ee dalka). In xagaaga heerkulka Gaadha ka +4 in +20 ° C.

roobabka

In waqooyi-galbeed dhaco roobab aad u sarreeya. Xaqiiqada ah in qayb ka this ee Cordillera ku yaal waddada Dabaylaha galbeed ah buunafuufid xusuus ka Badweynta Pacific. halkan roobabka - 3000 mm. Ma latitudes kulaylaha yar qoyan, sida tacsida hawada Oceanic ha u gaaraan. roobab Low ayaa sidoo kale sharaxayaa hadda qabow dal ka baxsan xeebaha. buuraleyda Gudaha Cordillera sidoo kale aan wax badan qoyan. Mountains ku yaalla goobaha dhexdhexaad ah cimilada subarctic, dadka fareen iyo kulaylaha gudahood.

Wabiyada iyo harooyinka of Cordillera ah

qayb ku ool ah oo webiyaasha galbeed ee qaaradda ayaa asal ahaan ay si hufan ee Cordilleras ah. Inta badan ay cunto waa barafka iyo barafka on xagaaga yimaado daadka. Wabiyaal buurta Kuwanu, degdegga. The ugu weyn iyaga ka mid ah - ee Colorado iyo Columbia. Glacial ama asal Kobenhagen, waa harooyinka Cordillera. On plateaus biyaha cusbada gudaha waa biyo-gacmeed. Waxaa haraadiga muddo dheer halkan inta lagu jiro cimilada qoyan, harooyinka waaweyn jirey.

dunida cuntada

flora aad u kala duwan ee Cordillera ah. kaynta dhilka leh muuqaal gaar ah oo ku yaalla ilaa 40 ° c. w. Halabuurka noocyada The, waxay aad buu hodan u yihiin. Fir, geed tirsah ah, qoryo beroosh ah, thuja (kedar ah cas) waa wakiilada caadiga ah iyaga ka mid ah. conifer Dhererka waa 80 mitir. Dhexdoodana ficil ahaan waa maya undergrowth Woody. Si kastaba ha ahaatee, noocyo kala duwan oo ku xoortay geedihii halkan koraan oo faro badan. Badan oo cover dhulka ee Muuse iyo ferns ah. In kaymaha dhilka halka u dhaqaaqo koonfurta bilaabaan inay dhici geed sonkorta, beroosh ah oo cad, geed huruud ah. Evergreen sequoia muuqataa koonfurta dheeraad ah. Sida qallayl ee 42 ° koonfureed. w., ku xoortay geedihii bedeli kaynta. Waxay geed rotem la yidhaahdo, Heather, iyo height inta badan aan ka badnayn laba mitir. Halkan waxa aad mararka qaarkood ka heli kartaa nooc oo kala duwan oo geedkii canbaha. cimilada huurka ee dhulka gudaha ah ee Cordillera ka hoos. Dadkaas iyaga ah mid caan ku ah kaymaha qalalan, iyo sidoo kale meelaha cidlada halophytic iyo sagebrush. Qaadashada dalcadaha roobka buuraha waa la daboolay si height a of 1200 kaymaha m canbaha.

Xayawaanka ee ku nool buuraha reer Cordillera ah

Halkee buuraha Cordillera ku yaalaan, waxaad ka heli kartaa a brown orso noolashooda - ilaashadaan badan oo qaarada Waqooyiga America. Dhali orso American madow, isagoo dhogorta madow dheer, deggan koonfur-galbeed ee nidaamka this. Isagu wuu wada baabbi'iyaa xoolihii iyo alaabtii boolida la goosanayo. Sidoo kale, waxaa jira dad badan oo lynxes, Dawacooyinku oo yeey. In qaybaha koonfureed ee buuraha waxaa badanaa laga helaa cayayaanka, mulacyada, masaska. Intaa waxaa dheer, waxaa deggan gila - legless qorratada laalaaday kaliya. xoolo badan oo meelaha dadku ku nool yihiin, ama la dilay, ama waa naadir. Qoraafiga iyo pronghorn (biciidka dhif dhaca) ku badbaadi oo keliya xoog ee barnaamijyada qaranka North American. Kaliya ee kaydka laga dheehan karo maanta duur badan.
