Intrusive igneous pob zeb txias los ntawm magma maj mam vim tias lawv tau faus rau hauv qab ntawm qhov chaw, yog li lawv muaj cov muaju loj. Extrusive igneous pob zeb txias los ntawm lava sai heev vim lawv tsim ntawm qhov chaw, yog li lawv muaj cov muaju me me.
Ntxiv mus, dab tsi yog qhov intrusive igneous pob zeb?
Intrusive pob zeb , kuj hu ua plutonic pob zeb , igneous pob zeb tsim los ntawm magma yuam mus rau hauv cov laus pob zeb nyob rau hauv qhov tob hauv lub ntiaj teb lub crust, uas tom qab ntawd maj mam solidifies hauv qab lub ntiaj teb saum npoo, txawm tias tom qab ntawd nws yuav tshwm sim los ntawm kev yaig. Igneous intrusion tsim ntau yam pob zeb hom. Saib kuj extrusive pob zeb.
Ib sab saum toj no, lub pob zeb igneous zoo li cas? Igneous pob zeb yog tuab heev thiab nyuaj. Tej zaum lawv yuav muaj lub ntsej muag iav. Metamorphic pob zeb kuj tuaj yeem muaj qhov zoo li iav. Koj tuaj yeem paub qhov txawv ntawm cov no los ntawm igneous pob zeb raws li qhov tseeb tias metamorphic pob zeb zoo li nkig, hnav, thiab xim dub opaque.
Nyob rau hauv no, yuav ua li cas intrusive igneous pob zeb?
Intrusive igneous pob zeb ua rau feem ntau ntawm igneous pob zeb thiab yog tsim los ntawm magma uas txias thiab solidifies nyob rau hauv lub crust ntawm lub ntiaj chaw (lub npe hu ua plutons), surrounded los ntawm pre-existing. pob zeb (hu ua lub teb chaws pob zeb ); cov magma txias maj mam thiab, vim li ntawd, cov no pob zeb yog coarse-grained.
Koj piav li cas txog cov pob zeb igneous?
Igneous yog siv rau piav pob zeb uas crystallize tawm ntawm kub molten khoom nyob rau hauv lub ntiaj teb hu ua magma. Thaum magma thawb los ntawm lub ntiaj teb lub pob zeb mus rau saum npoo, nws hu ua lava. Ob qho tib si magma thiab lava txias thiab tawv rau daim ntawv igneous pob zeb.
