Lub zog uas tsav Plate Tectonics suav nrog: Convection Nyob rau hauv lub Mantle (tsav cua sov) Ridge thawb (gravitational quab yuam ntawm lub kis ridges) Slab rub (gravitational quab yuam nyob rau hauv subduction aav)
Kuj paub, dab tsi yog lub zog tsav ntawm phaj tectonics quizlet?
Tectonic phaj txav yog tsav los ntawm gravitational rog txuam nrog ntau ntom lithosphere floating nyob rau ntawm qhov tsawg ntom asthenosphere. b. Tectonic phaj txav yog los ntawm convection nyob rau hauv lub mantle, qhov twg daim hlau yog passive rafts.
Tom qab ntawd, lo lus nug yog, vim li cas qhov ntom ntom suav tias yog lub zog tsav ntawm phaj tectonics? Qhov ntau dua ntawm qhov qub lithosphere txheeb ze rau lub hauv paus asthenosphere tso cai rau nws nkag mus rau hauv qhov sib sib zog nqus mantle ntawm subduction aav , muab feem ntau ntawm kev tsav tsheb rau phaj txav. Qhov tsis muaj zog ntawm asthenosphere tso cai rau cov phiaj xwm tectonic txav tau yooj yim mus rau thaj tsam subduction.
Ua raws li qhov xav tau, peb lub zog tsav ntawm phaj tectonics yog dab tsi?
Mantle convection currents, ridge laub thiab slab rub yog peb ntawm zog uas tau raug npaj ua lub ntsiab tsav tsheb ntawm phaj txav (raws li Dab tsi tsav lub daim hlau ? Pete Loader).
Qhov teeb meem cuam tshuam li cas hauv phaj tectonics?
Txoj kev xav ntawm phaj tectonics hais tias lub ntiaj teb cov khoom sab nrauv, lub lithosphere, tau muab cais ua daim hlau uas txav hla lub asthenosphere, molten sab sauv ntawm lub mantle. Oceanic thiab continental daim hlau tuaj ua ke, sib nrug, thiab sib cuam tshuam ntawm ciam teb thoob plaws ntiaj teb.

Dab tsi yog lub zog tsav ntawm kev sib sib zog nqus dej hiav txwv ncig?
Hauv dej hiav txwv sib sib zog nqus, qhov tseem ceeb ntawm kev tsav tsheb yog qhov sib txawv ntawm qhov ntom ntom, tshwm sim los ntawm salinity thiab kub variations (nce salinity thiab txo qhov kub ntawm cov kua ob qho tib si nce nws ntom). Muaj feem ntau tsis meej pem txog cov khoom ntawm cov kev ncig uas yog cua thiab ceev tsav
Yuav ua li cas convection nyob rau hauv lub mantle tsav phaj tectonics?
Convection tam sim no nyob rau hauv magma tsav phaj tectonics. Loj convection tam sim no nyob rau hauv lub aesthenosphere hloov tshav kub mus rau saum npoo, qhov twg plumes ntawm tsawg ntom magma tawg sib nrug ntawm daim hlau ntawm cov chaw sib kis, tsim divergent phaj ciam teb
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog qhov txawv ntawm lub zog siv zog thiab lub zog thauj khoom?
Raws li nrog cov dav hlau inclined, cov khoom yuav tsum tau txav mus los yog lub zog muaj zog los yog thauj khoom thiab kev siv zog yog lub zog muab tso rau hauv kev txav mus los ntawm lwm qhov kawg ntawm lub fulcrum
Dab tsi yog lub zog tsav phaj tectonics?
Lub zog uas tsav Plate Tectonics muaj xws li: Convection hauv Mantle (tsav cua sov) Ridge push (gravitational force at the spreading ridges) Slab rub (gravitational force in subduction zones)
