Amerika Te Tai Tokerau: te manawa me ona āhuatanga

Terrain Minerals Te Tai Tokerau America - ako katoa i roto i te kura i tenei ra i roto i te mau haapiiraa geography. He tika Knowledge o enei take mo te whakamātautau e kore anake, engari ano hoki mo te whanaketanga whānui. I muri i te katoa, me matau ia o tatou e ko te mata o te ao i runga i nei e ora tatou.

Amerika Te Tai Tokerau, te tanga o nei tatou e aparau i roto i tenei tuhinga rite te momo o te tuakitanga poutū Tonga Amerika. whitiki mano o nga maunga Cordillera hora haere te tai hauāuru ki te 7000 km. Pai io, ko te flat ko te hawhe te rawhiti o te tuawhenua. tenei katoa fokotu'u e te awhina o nga Amerika kua he pakuwha kaha. Heoi, i reira e nui ngā rerekētanga i waenganui i enei fenua. I roto i ngā, rite te pūnaha maunga Cordillera he nui whānui me te hanganga matatini atu Andes (i huaina ano hoki o'Anitesí Cordillera). ngā ratou o nga awhe pūnaha katoa, he motuhake rerekē hanganga nekeneke, me te arowhenua.

rohe rawhiti

kitea mārama tata katoa i runga i te Cordillera 5 orotektonicheskih roa rohe. Ko te tuatahi o enei, te rawhiti - Laramide Hanganga Maunga tupuke: Maunga Mackenzie, Brooks Range, Ridge Eastern Sierra Madre, Rocky Mountains. Ko te whakamutunga taea te wehea rite ki nga peculiarities o orography ki e rua nga wahi: te raki me te tonga. I waenganui ia ratou tu ki waho Yellowstone Plateau. puka straightness pū he kanapa āhuatanga orographic.

Front Range o te mau Mou'a Ofa'i

Front Range o te mau Mou'a Ofa'i (Amerika Te Tai Tokerau) he te manawa e whai ake nei: hora reira tata 2000 km i roto i te rārangi tika, e pa ana te haere tonutanga, tapatahi, me te taurite o tona hanganga arowhenua. Ridge mārama, karaunatia tihi teitei pari, te teitei o e tae 4000 m. Reira āta heke i roto i te rawhiti ki te Great Plains. Range mua ki te hauauru i te tetahi he nekeneke i roto i te wahi raki. I roto i te waenganui o te maunga iti. whiti ratou te awa Pis, i te mea tetahi o nga puna o te awa Mackenzie. Range mua i roto i te wahi tonga o whakawhänui. Kei te wehea te reira ki awhe motuhake, he nui te tiketike o nei: Lewis, Caribou, Selkirk. I roto i tenei wahi i reira ko nga tihi nui Front Range. Robson Ko te maunga (tairanga 3954 m) ko Maunga Columbia (3747 m). momo tipu o Amerika Te Tai Tokerau mahere whenua angamaheni o te Range mua. Kei te hoki āhuatanga ia i te glaciation tiketike, me te nui.

Rocky Mountains i roto i te wahi tonga

e kore e kotahi Rockies hiwi hanga i roto i te wahi tonga. Tenei e tito ratou o ngā huānga takitahi, i ētahi wā tawhiti, ka wehea e "pāka" - peihana whanui, e tohu ana i te wāhanga mania-rite e hono ki te poka wai nui Great Plains. Wāhanga o te tupuke (Sangre de Cristo, Wasatch) totoro tata i te raki ki te tonga. Ētahi atu (hei tauira, Uinta Mountains) - i roto i te ahunga te hauauru-rawhiti hāngai ki a ratou. utua teitei nui, me te whanui o tenei whitiki maunga e te kore o te tonu. Ko te rohe ki waenganui i nga Plains Great te rawa mārama whakahuatia me nga Rocky Mountains: te taiepa pari - te taha o te maunga. wāhanga tonga - he epiplatform angamaheni maunga e i hanga e i muri i te faaitoitoraa o te mata o tetahi o nga tüäpapa onamata enei.

Belt mania ā-me mania

Next - whitiki mania ā-me mania i hanga i roto i nevadiyskuyu whakakopa i runga i te tuawhenua o Amerika Te Tai Tokerau. Te tanga e āhuatanga e takai hanganga nevadiyskimi kanohi peniplenami. I roto i tenei rohe i reira ko te mania, e kua herea ki "whatiwhatinga" o te tūāpapa tawhito American Te Tai Tokerau, me te whakauria Cordillera (Northern Mass, Colorado Plateau). Ko te nui rawa mania he ◊Otumo◊unga Fraser, Yukon, te Afaa Rahi, Colombia, Te Tai Tokerau ko Central Mass, Colorado.

Basin Great

Basin Great - denudation mania, te nui rawa i roto i te rohe. Tenei rohe, nei whānui kei runga ki te 800 km, i roto i te whānui, ko te whakarerekētanga o papa flat, me te maunga ki te predominance o te mua. I te 1500m toharite whakaarahia mata mania. Heoi, rerekē nui i roto i te wahi tiketike. whakawhiti Plateau tupuke whakarara ki tiketike o e pā ana ki 3 km (Wheeler tihi - 3982 m). depressions hohonu, ka karanga Bolson, takoto i waenganui ia ratou. Kei te āhua-kopakia ana te reira, ka karapoti mai peihana, i te mea he wāhi o te pana i te wai ā-. Mate Valley - tetahi o ratou (-85 m).

Kei te maha kitea tihi Tuhinga (tae atu ki ngā mahuetanga o ngā puia).

Colorado Plateau me te Grand Canyon

Colorado Plateau - ko tetahi o tino ahurei nga koki o to tatou paraneta, mohiotia nei mo Amerika Te Tai Tokerau. Ko te tino ataahua tōna te tauturu. E ai ki tona hanganga arowhenua (poari whakapae toka parataiao maunga ratou wenua o reanga rerekē - i tahito ki te verhnepaleoziyskih takoto i runga i te whawhe tioata) ko te mania rite ki te tüäpapa American Te Tai Tokerau. Ko tōna mata - pukepuke mania, e tae te teitei o 3860 m.

Attraction o te mania ko te Grand Canyon (Te Tai Tokerau Amerika). E ngā mātauranga mahere whenua me te āhuarangi ki maha tūruhi tenei wahi. Grand Canyon (whakaahua i raro nei) i hanga e i te awa Colorado, i roto i te waenganui o tona akoranga. tae te reira i te hohonu o 1800 m, he whanui o 8 ki te 25 km i te mania, me te ki 1km i te taumata raro. titahatanga pari e ngā, āhuatanga rerekē o te Grand Canyon. puta ratou i te tukanga o te kino erosive me HUARERE. Ko te turanga, tioata o tāmau awhiowhio te teihana kuiti.

whitiki maunga i roto

Ko te rohe tuatoru - te maunga i roto - i te whitiki nevadiyskih awhe: Coast Mountains, te Range Alaska, te Mountains Cascade, te Sierra Nevada, me te Tāpae Puia Sierra Madre Occidental. rerekētanga te tika i waenganui i enei tupuke. toka ngiha mua roa i roto i to ratou hanganga. Cascade Mountains - batholith ki puia, tarona ki runga ki taua mea. Ko te hiwi o te Sierra Nevada ko te hangarite batholith karaihe nui ki te piki pari Aharoto hauauru, me te rawhiti.

whitiki synclinoria

Ko te tuawha rohe ko te synclinoria rohe. Tenei e tukupu ana o te rohe, i i hanga e i roto i te Neogene. Wāhanga o reira e māngai tēnei wā e ngā moana whanga, kuiti. I te whenua ko reira te raorao o te mate, te nui Central Valley, te wahapū o te awa o Colorado.

rohe tawhiti Te Hau-ā-uru

E rima nga wa - te uru tino. Ko te whitiki takutai o tupuke tipu te takai rite Aleut (i reira e 25 puia kaha), Kenai Peninsula, Island Ridge ki Victoria Peak (teitei - 2200 m), Chugachsky Ridge Peninsula Victoria, Tai maunga, Range Sierra Madre del Sur. He reo-tiketike katoa o ratou, ko te tihi tino nui i runga 2 km.

Tei runga i te whānuitanga o glaciation, te pakeke o ngā rohe ahopou orographic, tuaki nekeneke me erosional, kua wehea te Cordillera ki 4 rohe morphostructural: Cordillera o Mexico, te United States Cordillera Cordillera Cordillera o Canada me Alaska.

Ko te wahi ki te rawhiti o te fenua

He aha te tanga ki Amerika Te Tai Tokerau i roto i te rawhiti? Tatou i te reira. Ka rite ki te mea kua tuhia e matou, i whai ahua ai he tikanga flat i roto i te wahi ki te rawhiti o te fenua te mahere whenua American Te Tai Tokerau. Fele ko reira hanahana (Central, Laurentian) me mania teitei. Ko raorao haere te takutai: Primeksikanskaya, rohe Atlantic, Prigudzonskaya ko Mississippi i roto i nga taha o raro o taua te awa.

whitiki maunga Appalachian

I roto i Amerika Te Tai Tokerau, i roto i te rerekē ki te tonga, hora tetahi whitiki maunga haere te rohe ki te rawhiti - Appalachian. Tenei pae maunga pūnaha, i te Gulf o St. nga tikanga. Lawrence ki pā ana ki 33-32 ⁰ s. m., e ko tata 2,300 kiromita. Ko te motu o Newfoundland ko te hononga te raki. Appalachian - epiplatform reira maunga teitei. Ko te rerekētanga faufaa i waenganui i nga wahi te tonga, me te raki o te whānuitanga maunga meinga āhuatanga nekeneke, me te hanganga arowhenua. Graben Hudson Ko te rohe i waenganui i te raki, me te tonga Appalachian. Appalachians Northern rite te katoa - he mea mania tāwakawaka. Kei te nuinga te reira e pae maunga takitahi pae maunga ranei. Northern Appalachian Inaki te glaciation Quaternary. Na reira, ko te āhua o maunga inaianei - flat, ko nga tihi teitei anake circuses ki taiepa pari.

Southern Appalachians

Whakarerekētanga o te roa raorao whakarara me tupuke o rerekē Appalachians Southern. Mai i te rawhiti me te hauauru whakawhānui haere te waewae o te mania. Te reira i Piedmont i roto i te uru - he mania papatahi o denudation, i hanga nei e Early nga toka tioata Cambrian. Mai i te putanga mai te reira steeply ki te mekameka hauauru o pae maunga, tata tonu (Kohut, Unakite, Black, ae, nui, puru, me ētahi atu), Teitei - 1-1.5 km. Tenei "maunga tawhito" - otaota mātotoru Caledonide, te denudation rite.

tupuke whitiki me awaawa

Ko tētahi o nga wāhi tino faahiahia o te maunga Appalachian te kei ki te hauauru o ratou. Tenei pera-ka karanga Young Mountain, whitiki o tupuke me awaawa ranei. Here te tahi āhuatanga ngā o te tanga o Amerika Te Tai Tokerau. toka parataiao o te wā Paleozoic titoa te o te rohe katoa: awhe - shales me sandstones o te raorao - dolomites me limestones. Totoro hoki rau o kiromita ki te tonga-uru ki te raki-rawhiti o te totoro raina o maunga, whānui raorao kē ki flat-tihi heru ranei ki tupuke kuiti. I te teitei o 500-600 mita, te raro o awaawa. tupuke tihi tae 1-1.2 km. Valley tectonically tohu anticlinoria me tupuke he synclinoria. Ko te, i tenei wāhi te mārama kitea momo ōritengakore o te hanganga nekeneke o te puka hou, e kua he tanga konei i roto i Amerika Te Tai Tokerau. aroaro Photos o Appalachia te raro nei.

Ko te tauira o te tohanga, momo koaro o te tauturu ranei tenei. Kei te kitea te reira i roto i te maunga, ko te āhua onge, me te tino anaana i roto i te Appalachians. timata tenei momo o te tauturu i te rārangi e huaina ki "te tauturu Appalachian." Belt "maunga taitamariki" i roto i te uru whakapōnānā ana te Appalachian Plateau (Cumberland, Allegheny). Ko te protrusion tona tiketike ko 300-400 m. he mania tino teitei Piedmont tenei. takoto Ko tōna mata mata te rawhiti i te teitei o e pā ana ki 1.2 km, me te hauauru - 500 m wahi Plateau hohonu dissected awaawa ngā awa (take awaawa ki Aharoto kuiti, me te pari) ..

Well, i teie nei e i arotakehia poto te tanga o Amerika Te Tai Tokerau i roto i tenei tuhinga, tumanako tatou ka mama ki a ia mo te hanga i tona whakaaturanga.
