Lawv ob leeg convergent tsam, tab sis thaum ib dej hiav txwv phaj converges nrog a teb chaws Europe plate, ua dej hiav txwv phaj yog yuam hauv qab lub teb chaws Europe pla vim dej hiav txwv crust yog thinner thiab denser dua teb chaws Europe pob zeb.
Yog li ntawd, dab tsi txawv ntawm Oceanic Oceanic convergent phaj ciam teb ntawm dej hiav txwv continental convergent ciam teb?
Thaum ib daim phiaj dej hiav txwv ntsib a continental phaj ntawm a convergent ciam teb tus daim phiaj dej hiav txwv raug yuam hauv qab continental phaj thiab rhuav tshem. Cov convergent ciam teb nruab nrab dej hiav txwv thiab daim hlau continental tsim subduction thaj chaw. Cov daim phiaj dej hiav txwv raug thawb hauv qab continental phaj thiab yaj.
Tsis tas li ntawd, qhov twg yog thaj av hiav txwv continental convergent ciam teb? 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).
Dab tsi yog dej hiav txwv oceanic convergent ciam teb tsim?
Oceanic Convergent Boundaries . Thaum ob dej hiav txwv daim hlau sib tsoo, cov laus denser phaj subducts. Cov txiaj ntsig ntawm no tectonic kev sib tsoo yog zoo ib yam li cov koom nrog dej hiav txwv thiab continental daim hlau. Ib qhov tob tob yog tsim rau ntawm ntug hiav txwv.
Muaj pes tsawg daim phiaj dej hiav txwv muaj?
Major thiab Minor Tectonic Daim phiaj Lub xya loj daim hlau suav nrog African, Antarctic, Eurasian, North American, South American, India-Australian, thiab Pacific daim hlau . Qee tus menyuam yaus daim hlau suav nrog Arabian, Caribbean, Nazca, thiab Scotia daim hlau.

Puas yog ob txoj kab sib luag zoo sib xws lossis tsis sib xws?
Yog tias ob qhov sib npaug piav txog kab sib luag, thiab yog li cov kab uas tsis sib tshuam, qhov system yog ywj siab thiab tsis sib haum. Yog hais tias ob qhov sib npaug piav txog tib kab, thiab yog li cov kab uas hla tus lej tsis kawg, lub kaw lus yog nyob ntawm thiab sib xws
Koj tuaj yeem ua pov thawj li cas 2 daim duab peb sab zoo sib xws siv lub kaum sab xis sab SAS zoo sib xws postulate?
SAS Similarity Theorem hais tias yog ob sab hauv ib daim duab peb sab yog proportional rau ob sab hauv lwm daim duab peb sab thiab lub kaum sab xis nyob rau hauv ob qho tib si congruent, ces ob daim duab peb sab zoo ib yam. Ib qho kev hloov pauv zoo sib xws yog ib lossis ntau qhov kev hloov pauv tsis tu ncua ua raws li kev dilation
Yuav ua li cas peb hom convergent ciam teb sib txawv ntawm ib leeg?
Peb hom phaj ciam teb yog Convergent, Divergent thiab Transform. Ib qho dej hiav txwv-dej hiav txwv convergent: Ntawm no lub phaj denser mus rau hauv qab ntawm lwm yam nyob rau hauv ib tug subduction cheeb tsam. Continental-continental convergent: Thiab nyob rau hauv cov ntaub ntawv no lub thickness ntawm lub crust doubles raws li lub convergent ua rau roob
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
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
