Cape Murchison, nyob rau ntawm ceg av qab teb, yog qhov chaw sab qaum teb ntawm Canadian av loj thiab, raws li, North America. Qhov no yog ib qho ntawm cov ntsiab lus sab qaum teb ntawm lub ntiaj teb. Qhov deb ntawm qhov chaw no mus rau sab qaum teb yog 64 kilometers.
Nyob rau hauv tsab xov xwm koj tuaj yeem paub luv luv txog qhov xwm txheej hnyav hnyav no thiab kawm txog qhov twg Butia Peninsula nyob thiab nws yog dab tsi.
Canadian Arctic Archipelago
Cov Islands tuaj loj tshaj plaws uas tsim cov archipelago:
- Baffin Island nrog thaj tsam ntawm 476 txhiab square meters. kilometers,
- Ellesmere Island (thaj tsam 203 txhiab sq. km),
- Victoria Island (ntau dua 213 txhiab sq. km).
Cov cheeb tsam suav nrog ob thaj av me me ntxiv uas nyob deb mus rau sab qaum teb - Boothia thiab Melville. Nyob rau hauv nruab nrab ib feem ntawm lub Arctic archipelago, nyob rau hauv cov kob ntawm Bathurst, ib tug ntawm ob lub ntsiab terrestrial sib nqus ncej nyob.
keeb kwm me ntsis
cheeb tsam no tau tshawb pom los ntawm tus kws tshaj lij navigator, tus neeg tshawb nrhiav British polar John Ross thaum lub sijhawmTxoj kev taug kev mus rau qhov tseem ceeb ntawm 1829-1833. Lub npe tau muab rau kev hwm ntawm Felix Bout (brewer), uas tau los ua tus txhawb nqa ntawm txoj kev mus ntev no.
Nyob rau sab hnub poob ntawm Boothia ceg av qab teb, tus tub xeeb ntxwv ntawm James Ross nrhiav pom North Sib Nqus Ncej. Roald Amundsen (tus neeg tshawb nrhiav nto moo los ntawm Norway) hauv xyoo 1909 tau taug kev raws ntug dej hiav txwv sab hnub poob ntawm Butia ntawm lub sledge. Lwm tus neeg taug kev, Canadian Henry Larsen (Arctic explorer), tau tshawb nrhiav tag nrho thaj chaw ntawm ceg av qab teb xyoo 1940 thaum mus ncig ua si los ntawm Northwest Passage los ntawm 1940 txog 1942.
Qhov chaw
Lub Boothia Peninsula nyob hauv North America. Nws yog Ameslikas hu ua Butia Felix.
Qhov chaw no yog Canadian Arctic sab qab teb ntawm Somerset Island. Cov ceg av qab teb nto moo rau Cape Murchison. Cov kob yog cais los ntawm lub mainland ntawm Canada los ntawm ib tug saw ntawm cov pas dej loj, thiab los ntawm Somerset los ntawm lub Bello Strait, qhov ntev ntawm uas yog hais txog ob kilometers. Ntawm nws thaj chaw yog lub zos me me ntawm Talloyoak, nto moo rau qhov tsuas yog kev sib hais haum nyob rau sab qaum teb latitudes.
piav qhia txog ceg av qab teb thiab ib puag ncig
Lub nyem ntawm Boothia Peninsula (Canada) yog lub roob toj siab, qhov siab uas ncav cuag ntau tshaj 500 meters, thiab nyob ib puag ncig los ntawm ntug hiav txwv dav dav. Thaj chaw ntawm cov kob yog 32,300 sq. kilometers.
Cov ceg av qab teb txuas mus rau thaj av loj los ntawm isthmus,xyaum torn sib sib zog nqus ntawm cov pas dej loj loj thiab ob lub bays loj. Cov ceg av qab teb raug ntxuav los ntawm cov dej ntawm Boothia Bay thiab Franklin Strait. Qhov thib ob cais cov ceg av qab teb ntawm sab qab teb sab hnub tuaj ntawm Prince of Wales Island, kuj yog ib feem ntawm Canadian Arctic Archipelago. Nyob rau sab hnub tuaj, hla lub Bay ntawm Butia, yog cov kob loj tshaj plaws hauv cov koog pov txwv, Baffin Island.
Nws yuav tsum tau muab sau tseg tias cov dej kub ntawm Arctic hiav txwv nyob rau saum npoo ntawm Butia Bay (ntev 518 kilometers, dav 220 kilometers) nyob rau hauv lub yim hli ntuj yog mus txog 1 ° C. Tag nrho lub xyoo nws yog them nrog dej khov, rarefied tsuas yog nyob rau hauv lub caij ntuj sov lub hli tas los. Cov nroj tsuag ntawm ceg av qab teb yog tundra.
me ntsis txog cov ntsiab lus siab heev
Canada occupies yuav luag ib nrab ntawm lub mainland North America. Cov ntsiab lus tseem ceeb tshaj plaws ntawm thaj chaw ntawm lub xeev no thiab thaj av loj coincide ob leeg nyob rau sab hnub tuaj thiab sab qaum teb. Sab hnub tuaj yog Cape St. Charles (52 degrees 24 feeb sab qaum teb latitude, 55 degrees 40 feeb sab hnub poob longitude). Nws nyob ze lub nroog Toronto thiab yog ib qho chaw ntawm Labrador Peninsula.
Tsis txhob yuam kev cov ntsiab lus siab ntawm Canada thiab, raws li, North America nrog cov ntsiab lus zoo sib xws hauv Tebchaws Meskas. Lub ntsiab lus tseem ceeb sab qaum teb ntawm thaj av loj yog Cape Murchison, nyob hauv Arctic. Nws belongs rau thaj chaw ntawm Canada thiab yog ib qho ntawm cov ntsiab lus tseem ceeb ntawm lub ntiaj teb ntiaj teb, tsis suav Greenland.
Cape Murchison
Lub cape belongs rau Canadian cheeb tsam ntawm Kitikmeot. Nws yog sab qab teb ntug dej hiav txwv ntawm Belleau, nyob nruab nrab ntawm Somerset Island thiabPeninsula ntawm Butia. Lub strait muaj npe tom qab Yauxej Rene Murchison, uas thawj zaug tshawb xyuas cov ceg av qab teb. Kev tshawb nrhiav cov cim ntawm John Franklin, uas ploj lawm hauv Arctic, ua rau tus neeg tshawb nrhiav Fabkis-tus neeg taug kev mus kawm cov chaw no hauv xyoo 1852.
Qhov chaw hnyav no yog ib puag ncig permafrost yuav luag txhua xyoo puag ncig. Cape tswj - 71 degrees. 50 feeb sab qaum teb latitude, 94 degrees. 45 feeb sab hnub poob.
Talyoak
Lub nroog me me no nyob rau sab qab teb ntawm Butia Peninsula, 128 km sab hnub poob ntawm lub nroog Nunavut. Koj tuaj yeem mus rau lub zos los ntawm dav hlau los ntawm tshav dav hlau ntawm tib lub npe, nyob ntawm qhov deb ntawm tsuas yog ib mais sab hnub poob ntawm Taloyoak. Thaum kawg ntawm lub caij ntuj sov, tsis pub dhau ob peb lub lis piam, koj tuaj yeem hla dej mus rau cov nroog ze ntawm Kugaaruk thiab Gjoa Haven. Tsis muaj txoj kev mus rau kev sib hais haum.
Lub zos hu ua Spence Bay mus txog thaum nruab nrab lub caij ntuj sov 1992. Cov pejxeem yog 809 (raws li xyoo 2006).
North of Taloyoak muaj pob zeb loj loj piv rau cov pob zeb nto moo Uluru hauv Australia.
In xaus, me ntsis txog xwm
Qhov twg Butia Peninsula (Ntiaj Teb Sab Qab Teb) nyob, thaj chaw yog thaj chaw loj ntawm Arctic suab puam, uas, thaum koj tsiv mus rau sab qab teb, tau hloov los ntawm tundra, pib ntawm ntug ntawm cov daus nyob mus ib txhis.
Nyob rau hauv cov huab cua hnyav li no, ntawm cov av khi los ntawm permafrost, tsuas yog meagerCov nroj tsuag tundra sawv cev los ntawm cov tshuaj ntsuab txhua xyoo thiab cov nroj tsuag.
