Cov Eurasian Phaj yog tectonic phaj uas suav nrog feem ntau ntawm cov teb chaws ntawm Eurasia (ib thaj av muaj xws li kev cai teb chaws ntawm cov teb chaws Europe thiab Asia), nrog rau qhov tshwj xeeb tshwj xeeb ntawm Indian subcontinent, Arabian subcontinent, thiab thaj tsam sab hnub tuaj ntawm Chersky Range nyob rau sab hnub tuaj Siberia.
Ntawm no, puas yog Eurasian phaj convergent los yog divergent?
Eurasian tectonic phaj yog ib qho loj tshaj plaws nyob rau hauv lub ntiaj teb, hla tag nrho cov Asia thiab Europe. Txawm hais tias complex, lub active tectonics raws ciam teb ntawm lub phaj yuav roughly summarized los ntawm sib txawv ciam teb mus rau sab hnub poob / sab hnub poob, thiab convergent ciam teb rau sab hnub tuaj / sab hnub tuaj.
Kuj Paub, puas yog daim phiaj Eurasian ib thaj tsam sib koom ua ke? Sab qaum teb ntawm lub phaj yog a convergent ciam teb qhov twg African phaj yog subducting hauv qab no Eurasian phaj . Subduction zones yog convergent ciam teb , thiab qhov twg lawv sib tsoo, ib qho phaj dhia hauv qab lwm yam. Hauv qhov no, African phaj yog dhia dej hauv qab Eurasian phaj.
Tom qab ntawd, lo lus nug yog, hom phaj ciam teb yog Eurasian phaj?
Ib tug txheej txheem cej luam ntawm Eurasian Phaj Sab hnub poob qhia ib divergent phaj ciam teb nrog rau North American phaj . Sab qab teb ntawm Eurasian phaj nyob ze rau Arabian, Indian thiab Sunda daim phiaj. Nws straddles raws Iceland qhov twg nws kua muag lub teb chaws nyob rau hauv ob cais pieces ntawm tus nqi ntawm 2.5 mus rau 3 cm ib xyoo.
Txoj kev twg yog Eurasian phaj txav?
Cov Eurasian Phaj txav sab qaum teb ob centimeters txhua txhua xyoo. Cov Eurasian Phaj yog qhov thib peb qeeb tshaj plaws mov phaj , tom qab North American thiab South American tectonic daim hlau . Cov kev txav mus los ntawm Eurasian Phaj yog tsim los ntawm qhov ntws ntawm magma hauv qab lub ntiaj teb nto, los yog crust.

Dab tsi yog qhov txawv ntawm continental drift seafloor kis thiab phaj tectonics?
Continental drift txoj kev xav tau tsim los piav qhia tias kev sib kis hauv hiav txwv yuav tsum cuam tshuam li cas rau sab av loj. Phaj Tectonic txoj kev xav tau tsim los piav qhia qhov chaw ntawm dej hiav txwv trenches, volcanoes thiab qhov chaw ntawm ntau hom av qeeg
Puas yog Okhotsk phaj oceanic lossis continental?
Cov dej hiav txwv Pacific Plate subducts nyob rau hauv North American Phaj (tsim los ntawm ob sab av loj thiab dej hiav txwv) ua rau Aleutian Trench. Dej hiav txwv Pacific phaj subducts hauv qab lub teb chaws Okhotsk Phaj ntawm Nyiv Trench
Lub phaj Eurasian tuab npaum li cas?
Cov blocks raug tshem tawm feem ntau yog ntau pua kilometers dav, 50-100 km ntev, thiab tsuas yog ob peb kilometers tuab
Yuav ua li cas thaum lub Continental thiab Continental Phaj sib tsoo?
Yuav ua li cas thaum ob daim hlau continental sib tsoo? Hloov chaw, kev sib tsoo ntawm ob daim phiaj sab av loj crunches thiab folds lub pob zeb ntawm tus ciam teb, nqa nws thiab ua rau tsim cov roob thiab roob
Puas yog phaj tectonics thiab continental drift tib yam?
Continental drift piav qhia txog ib qho ntawm txoj kev ntxov tshaj plaws uas cov kws tshawb fawb xav tias cov teb chaws tsiv mus rau lub sijhawm. Niaj hnub no, txoj kev xav ntawm continental drift tau hloov los ntawm kev tshawb fawb ntawm phaj tectonics. Txoj kev xav ntawm kev sib tw hauv av feem ntau cuam tshuam nrog tus kws tshawb fawb Alfred Wegener
