Lub roob hauv Scandinavian Peninsula ntawm Northern Europe, nrog rau tag nrho ntev ntawm 1700 km thiab dav ntawm 1300 km, hu ua Scandinavian Toj siab. Lub sab hnub poob ntawm lub roob slopes mus rau sab qaum teb Hiav txwv, tsim sheer thiab ntxhab coasts, Peninsulas, capes, Islands tuaj. Txoj kev ntxhab thiab kev nkag tsis tau ntawm cov roob yog pov thawj los ntawm 178 qhov tunnels tso rau ntawm ntu ntawm Oslo-Bergen railway (Norway).

Sab hnub tuaj maj mam poob thiab hla mus rau Norland Plateau. Cov roob Scandinavian yog cov toj siab, uas muaj cov elongated ridges, toj siab, thiab intramountain depressions. Nyob rau hauv ntau qhov chaw muaj leveled nto, txiav los ntawm tob fjords thiab hav. Cov kev pab niaj hnub no tau tsim vim dej yaig, dej khov, cua thiab daus.

Lub roob roob tsim ntau heev fjords, uas tau tsim nyob rau hauv lub zog ntawm lub zog ntawm glaciers. Cov no yog hiav txwv bays, tob txiav mus rau hauv ib ncig ntawm lub teb chaws, nrog siabpob zeb ntug dej hiav txwv. Raws li txoj cai, qhov tob ntawm Scandinavian fjords ncav cuag ib mais.

Nws ntseeg tias cov roob Scandinavian qis. Qhov siab tshaj plaws ncov - Mount Galkhepiggen nrog qhov siab ntawm 2469 m - nyob rau sab qab teb txoj kab nqes ntawm lub roob, hauv Norway. Qhov siab tshaj plaws hauv Sweden - Mount Kebnekaise (2111 m) - nyob rau sab qaum teb ntawm ceg av qab teb. Lub roob ntawm Scandinavia yog npog nrog glaciers, uas yog suav tias yog qhov loj tshaj plaws nyob rau hauv cov teb chaws Europe. Kev nyab xeeb nyob rau hauv cov cheeb tsam no yog nruab nrab, tsuas yog nyob rau hauv lub strip ntawm sab qaum teb deb - subarctic.

Ntawm thaj chaw ntawm Sweden, hauv roob Scandinavian (hauv Lapland), muaj lub tebchaws loj "Sarek". Nws tau tsim muaj xyoo 1909 thiab npog thaj tsam ntawm 194,000 hectares. Ntawm thaj chaw no muaj ntau dua 90 lub roob siab nrog qhov siab ntawm 1800 meters. Ntawm lawv yog roob hav dej, dej tsaws tsag, gorges thiab 100 glaciers.

Cov roob Scandinavian tau nkag los ntawm cov dej ntws sib sib zog nqus, uas yog tsim los ntawm qhov tseem ceeb ntawm huab cua hauv hiav txwv ntub dej thiab kev sib tsoo ntawm cov roob siab. Rivers, raws li txoj cai, yog luv luv thiab puv-ntws, puv dej tsaws tsag thiab suav tsis txheeb. Lawv qhov siab tshaj plaws filling pib thaum lub caij nplooj ntoos hlav, feem ntau los ntawm cov daus yaj thiab nag hnyav, tsawg dua los ntawm cov dej khov. Vim qhov kev kub ceev ntawm tam sim no, dej khov tsis tsim ntawm cov dej hauv lub caij ntuj no. Cov roob hauv Europe no muaj ntau lub pas dej ntawm tectonic-glacial keeb kwm.

Qhov twg qhov siab ntawm lub roob nce mus txog 1000 meters nyob rau sab qab teb thiab mus txog 500 meters nyob rau sab qaum teb, cov slopes yog them nrog coniferous taiga hav zoov. Hav zoovwestern slopes alternate nrog shrub zaub thiab peat bogs. Hauv qhov no, pines thiab spruces predominate. Tshaj li qhov siab no, txoj siv sia ntawm birch sparse hav zoov txuas mus rau qhov siab ntawm 200 m, uas tau hloov los ntawm thaj tsam ntawm roob tundra. Cov neeg nyob hauv zos siv thaj chaw no rau tsiaj txhu thaum lub caij ntuj sov.

Nyob rau sab hnub tuaj ntawm cov roob, dav-leaved thiab mixed forests predominate. Lub fauna ntawm Scandinavian roob yog sawv cev los ntawm hares, hma, elk, reindeer, squirrels, roe mos lwj, ntsaws ruaj ruaj. Ntawm cov noog nyob rau hauv hav zoov muaj hazel grouse, dub grouse, capercaillie, ntawm ntug hiav txwv dej thiab pas dej - waterfowl. Muaj ntau ntses coj mus muag hauv hiav txwv thiab dej hiav txwv.

Lub roob Scandinavian yog nplua nuj nyob rau hauv deposits ntawm ores ntawm pyrites, tooj liab, hlau, txhuas thiab titanium. Muaj cov roj cia nyob rau sab qaum teb Hiav Txwv, sab ntug dej hiav txwv.
