Rov qab faults tshwm sim ntawm convergent phaj ciam teb, thaum ib txwm faults tshwm sim ntawm divergent phaj ciam teb. Av qeeg nrog kev tawm tsam-plam faults ntawm hloov Phaj ciam feem ntau tsis ua rau tsunami vim tias muaj me me lossis tsis muaj ntsug.
Kuj paub, dab tsi yog lub phaj ciam teb txhaum?
Tectonic Daim ntawv qhia nta. Hloov pauv Phaj Ciam yog qhov chaw uas ob daim hlau swb dhau ib leeg. Qhov tawg tsam uas tsim ib qho kev hloov pauv phaj ciam teb yog lub npe hu ua transform txhaum . Feem ntau hloov ua txhaum muaj nyob rau hauv dej hiav txwv phiab thiab txuas offsets nyob rau hauv nruab nrab-dej hiav txwv ridges.
Kuj Paub, dab tsi phaj ciam ua rau trench? Tshwj xeeb, dej hiav txwv trenches yog ib qho ntawm kev sib koom ua ke ntawm cov phaj ciam teb, qhov twg ob lossis ntau daim phiaj sib ntsib. Nyob rau hauv ntau qhov sib koom ua ke ciam teb, ntom lithosphere melts los yog swb hauv qab lithosphere tsawg-dense nyob rau hauv cov txheej txheem hu ua subduction , tsim lub trench.
Xav txog qhov no, lub phaj ciam teb twg ua rau av qeeg?
Phaj Ciam : Divergent, Convergent, thiab Transform. Kev txav mus rau hauv cov cheeb tsam nqaim nrog phaj ciam teb ua rau feem ntau av qeeg . Feem ntau seismic kev ua ub no tshwm sim ntawm peb hom phaj ciam teb -Divergent, convergent, thiab transform. Raws li cov daim hlau tsiv mus nyob ib leeg, qee zaum lawv tau ntes tau thiab muaj kev ntxhov siab.
Vim li cas kev txhaum feem ntau tshwm sim ntawm cov ciam teb phaj?
Ib qho kev so hauv lub cork ntawm crust qhov twg pob zeb nto plam ib leeg. Vim li cas ua txhaum feem ntau tshwm sim nrog phaj ciam teb ? Vim qhov no yog qhov twg lub zog ntawm phaj zog thawb los yog rub lub crust kom lub crust tawg.

Cov volcanoes twg nyob rau ntawm convergent phaj ciam teb?
Volcanoes ntawm convergent phaj ciam teb yog pom nyob rau hauv lub Pacific hiav txwv phiab, feem ntau nyob rau ntawm ntug dej hiav txwv Pacific, Cocos, thiab Nazca daim hlau. Trenches cim subduction zones. Cov Cascades yog cov saw hlau ntawm cov hluav taws kub ntawm ib thaj tsam sib koom ua ke qhov twg cov phaj dej hiav txwv yog subducting hauv qab daim phiaj av
Dab tsi phaj ciam ua daim ntaub thaiv volcanoes?
sib txawv Raws li txoj cai, qhov chaw thaiv hluav taws xob feem ntau tsim? Shield volcanoes muaj nyob thoob ntiaj teb. Lawv ua tau daim ntawv hla cov hotspots (cov ntsiab lus uas magma los ntawm hauv qab lub qhov dej ntws), xws li Hawaiian-Emperor seamount chain thiab Galápagos Islands, los yog ntau tshaj qhov chaw sib cais, xws li Icelandic daim thaiv thiab cov tiv thaiv volcanoes ntawm East Africa.
Yuav ua li cas faults thiab phaj ciam teb muaj feem xyuam nrog?
Phaj ciam yog ib txwm faults, tab sis tsis yog tag nrho cov faults yog phaj ciam teb. Kev txav ntawm daim phiaj txheeb ze rau ib leeg distors lub crust nyob rau hauv lub cheeb tsam ntawm cov ciam teb tsim systems ntawm av qeeg faults. Thaum lub nthwv dej no ncav cuag tus neeg soj ntsuam, qhov kev txav nrawm ntawm lub ntiaj teb tau txhais tias yog av qeeg
Dab tsi ntawm tectonic phaj ciam teb yog Mount Pinatubo rau?
Eurasian Hauv qhov no, hom phaj ciam teb yog Mount Pinatubo nyob rau? Mount Pinatubo nyob rau ntawm ib thaj tsam ntawm Continental Eurasian thiab Oceanic Philippine phaj . Lub Oceanic Philippine phaj tab tom raug thawb hauv qab lub teeb Continental Eurasian phaj .
Uas tsim nyob rau hauv lub hiav txwv continent convergent phaj ciam teb?
Piv txwv ntawm cov dej hiav txwv-convergent ciam teb yog subduction ntawm Nazca Phaj nyob rau hauv South America (uas tau tsim lub Andes Roob thiab lub Peru Trench) thiab subduction ntawm lub Juan de Fuca phaj nyob rau hauv North America (tsim lub Cascade Range)
