Piv txwv ntawm 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).
Yog li ntawd, ua li cas cov ntaub ntawv ntawm ib tug continental oceanic convergent ciam teb?
Av qeeg muaj zog, volcanic roob lossis volcanic arc roob ranges yog dab tsi Convergent ciam teb daim ntawv ntawm qhov chaw thaum lub dab dej dej hiav txwv phaj melts. Lwm yam nta muaj xws li dej hiav txwv trenches, kob arcs, submarine roob ranges, thiab kab txhaum tag nrho daim ntawv nrog tectonic phaj ciam teb.
Ib yam li ntawd, dab tsi 3 yam tsim los ntawm Convergent ciam teb ntawm dej hiav txwv thiab dej hiav txwv crust? Peb muaj peev xwm yog dej hiav txwv crust rau dej hiav txwv crust , dej hiav txwv crust mus rau continental pob zeb , los yog continental pob zeb mus rau continental pob zeb . Yog tias tsawg kawg ib qho ntawm cov slabs ntawm lithosphere yog dej hiav txwv , uas dej hiav txwv lub phaj yuav plunge rau hauv lub trench thiab rov qab mus rau hauv lub mantle.
Ib yam li ntawd, yuav ua li cas tshwm sim ntawm oceanic continental convergent phaj ciam teb?
Thaum twg teb chaws Europe thiab daim phiaj dej hiav txwv sib tsoo, lub thinner thiab ntau ntom daim phiaj dej hiav txwv yog overridden los ntawm thicker thiab tsawg ntom continental phaj . Cov daim phiaj dej hiav txwv raug yuam mus rau hauv lub mantle hauv tus txheej txheem hu ua "subduction." Raws li cov daim phiaj dej hiav txwv nqis, nws raug yuam mus rau hauv qhov kub thiab txias ib puag ncig.
Qhov twg yog daim ntawv convergent ciam teb?
Convergent ciam teb tshwm sim ntawm oceanic-oceanic lithosphere, dej hiav txwv-continental lithosphere, thiab continental-continental lithosphere. Cov yam ntxwv geological cuam tshuam nrog convergent ciam teb sib txawv nyob ntawm seb hom crust. Phaj tectonics yog tsav los ntawm convection hlwb nyob rau hauv lub mantle.

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 yog txheej txheem hu ua uas tsim cov dej hiav txwv tshiab hauv pem teb los ntawm diverging daim hlau?
Seafloor kis tau tus txheej txheem uas tshwm sim nyob rau hauv nruab nrab ntug dej hiav txwv ridges, qhov twg tshiab dej hiav txwv crust yog tsim los ntawm volcanic kev ua si thiab maj mam txav deb ntawm lub ridge
Yuav ua li cas cov ntaub ntawv nyob rau hauv cov cheeb tsam uas oceanic daim hlau diverge thiab tshiab seafloor yog tsim abyssal plains continental txee continental txoj kab nqes mid hiav txwv ridge?
Lub continental txoj kab nqes thiab nce yog hloov pauv ntawm crustal hom, thiab lub abyssal plain yog underlain los ntawm mafic oceanic crust. Oceanic ridges yog diverging phaj ciam teb qhov twg dej hiav txwv lithosphere tshiab tsim thiab dej hiav txwv trenches yog converging phaj ciam teb uas dej hiav txwv lithosphere yog subducted
Lub ntiaj teb nyob rau hauv orbit nyob ib ncig ntawm lub hnub qub uas tsis yog peb lub hnub?
Cov Lus Teb luv luv: Cov ntiaj chaw uas nyob ib puag ncig lwm lub hnub qub hu ua exoplanets. Tag nrho cov ntiaj chaw nyob rau hauv peb lub hnub ci system orbit ncig lub hnub. Cov ntiaj chaw uas nyob ib ncig ntawm lwm lub hnub qub yog hu ua exoplanets. Exoplanets yog qhov nyuaj heev kom pom ncaj qha nrog telescopes
Qhov twg yog ib qho piv txwv ntawm ib tug dej hiav txwv continental convergent ciam teb?
Ib qho piv txwv ntawm hom dej hiav txwv-continental convergent ciam teb yog lub roob Andes ntawm sab hnub poob South America. Ntawm no Nazca phaj yog subducting hauv qab South American Phaj
