Dej hiav txwv trenches, volcanoes, kob arcs, submarine roob ranges, thiab kab txhaum yog piv txwv ntawm cov yam ntxwv uas ua tau form ua phaj tectonic ciam teb . Thaum tshav kub kub nyob rau hauv lub asthenosphere tsim convection tam sim no ua rau tectonic daim hlau txav mus rau ob peb centimeters ib xyoos twg txheeb ze txhua lwm yam.
Xav txog qhov no, yuav ua li cas tshwm sim ntawm txhua lub phaj ciam teb?
Ib divergent ciam teb tshwm sim thaum ob tectonic daim hlau txav deb ntawm txhua lwm yam. Ib tug saw ntawm volcanoes feem ntau tsim parallel rau convergent phaj ciam teb thiab muaj zog av qeeg nyob ib ncig ntawm cov no ciam teb . Hauv convergent phaj ciam teb , dej hiav txwv crust feem ntau raug yuam mus rau hauv lub mantle uas nws pib yaj.
Qhov thib ob, 3 hom convergent ciam teb yog dab tsi thiab lawv ua dab tsi? Muaj peb hom convergent ciam teb txhua nrog nws tus kheej lub txim.
- Oceanic-Continental Convergence. Thawj hom convergent ciam teb yog Oceanic-Continetal Convergence.
- Oceanic-Oceanic Convergence. Lwm hom yog Oceanic-Oceanic Convergence.
- Continental-Continental Convergence.
Ua li no, lub phaj ciam txhais li cas?
Phaj ciam teb yog ntug qhov twg ob daim hlau ntsib. Feem ntau cov dej num geological, suav nrog volcanoes, av qeeg, thiab roob tsev, muaj nyob rau ntawm phaj ciam teb . Divergent phaj ciam teb :ob ua daim hlau txav deb ntawm ib leeg.
Dab tsi yog 4 daim ntawv ciam teb?
Phaj Ciam Ciam: Convergent, Divergent, Hloov
- Divergent: extensional; daim phiaj sib nrug. Spreading ridges, phiab-range.
- Convergent: compressional; daim phiaj txav mus rau ib leeg. Xws li: Subduction zones thiab roob tsev.
- Hloov: shearing; daim hlau swb dhau ib leeg. Strike-slip motion.
Pom zoo:
Dab tsi ntawm daim phiaj ciam teb yog Philippines?
Philippine Sea Phaj. Lub Philippine Sea phaj yog tectonically txawv nyob rau hauv uas yuav luag tag nrho cov ciam teb yog convergent. Lub phaj Pacific yog subducting hauv qab Philippine Hiav Txwv Phaj mus rau sab hnub tuaj thaum sab hnub poob / qaum teb sab hnub poob ntawm Philippine Sea phaj yog subducting hauv qab lub continental Eurasian phaj
Dab tsi ntawm daim phiaj ciam teb ua av qeeg tob tshaj plaws tshwm sim?
Feem ntau, cov av qeeg tob tshaj plaws thiab muaj zog tshaj plaws tshwm sim ntawm cov phaj sib tsoo (lossis subduction) ib cheeb tsam ntawm convergent phaj ciam teb
Dab tsi ntawm daim phiaj ciam teb ua rau muaj av qeeg hauv San Francisco xyoo 1906?
Pacific Phaj (nyob rau sab hnub poob) swb kab rov tav qaum teb sab hnub poob txheeb ze rau North American Phaj (nyob rau sab hnub tuaj), ua rau av qeeg raws San Andreas thiab muaj feem cuam tshuam. Lub San Andreas txhaum yog ib qho kev hloov pauv ntawm ciam teb, ua kom haum rau kab rov tav cov lus tsa suab
Dab tsi ntawm daim phiaj ciam teb yog av qeeg Kobe?
Av qeeg uas ntaus Kobe thaum lub caij ntuj no xyoo 1995 ntsuas qhov loj 7.2 ntawm Richter nplai (lossis 6.9 ntawm qhov ntsuas tam sim no ntau dua). Ntawm daim phiaj no, lub phaj Pacific tau raug thawb hauv qab Eurasian phaj, kev ntxhov siab tsim thiab thaum lawv tso lub ntiaj teb co co
Dab tsi ntawm daim phiaj ciam teb yog Yellowstone?
Lub North American Phaj yog rifting tsim magma plume ua rau geysers. Qee lub sij hawm lub ntiaj teb lub pob zeb tawg thiab cov kab nrib pleb hauv lub nplhaib qauv yuav ncav cuag lub magma reservoir tso siab thiab lub roob hluav taws yuav tawg. Yellowstone nyob nrog lub phaj tectonic tsis yog phaj ciam teb
