Constructive phaj ciam teb yog thaum muaj ob daim hlau txav deb ntawm ib leeg. Lawv hu ua daim hlau tsim vim thaum lawv sib ncaim, magma sawv hauv qhov sib txawv- qhov no tsim cov volcanoes thiab nws thiaj li tshiab crust. Kev puas tsuaj phaj ciam teb yog thaum dej hiav txwv thiab continental daim hlau txav mus ua ke.

Nyob rau hauv no txoj kev, dab tsi yog constructive phaj margin?

A tsim nyog (tensional) phaj ciam teb tshwm sim qhov twg daim hlau txav sib nrug. Feem ntau ntawm cov no phaj npoo nyob hauv qab dej hiav txwv. Raws li cov daim hlau txav sib nrug magma nce los ntawm lub mantle mus rau lub ntiaj teb nto. qhov nce magma daim ntaub thaiv volcanoes.

Qhov thib ob, qhov sib txawv ntawm kev puas tsuaj thiab kev sib tsoo phaj yog dab tsi? Oceanic rau dej hiav txwv thiab continental rau dej hiav txwv yog hu ua kev puas tsuaj daim ntawv ciam teb vim ib tug crust yog subducted nyob rau hauv lwm yam. Continental mus rau continental hu ua kev sib tsoo phaj ciam teb vim lawv yog ntawm tib qhov ceev thiab ob lub crusts tuaj yeem sib tsoo nrog rau ib leeg tsim fold roob.

Ib yam li ntawd, av qeeg tshwm sim li cas ntawm kev tsim phaj npoo?

Constructive phaj margins Ntawm a constructive phaj margin tus daim hlau txav deb ntawm ib leeg. Thaum qhov no tshwm sim lub magma los ntawm lub mantle nce mus ua (los yog tsim) av tshiab nyob rau hauv daim ntawv ntawm ib tug shield volcano. Lub zog ntawm lub daim hlau tshaj lub mantle tuaj yeem ua rau av qeeg.

Dab tsi yog 4 phaj margins?

Muaj peb hom phaj tectonic ciam teb : divergent, convergent, thiab transform phaj ciam teb . Daim duab no qhia txog peb yam tseem ceeb ntawm phaj ciam teb : divergent, convergent, thiab transform.
