Volcanic pob zeb yog pob zeb tsim thaum lavacools thiab solidifies ntawm lub ntiaj teb nto. Volcanic pob zeb tseem hu ua 'extrusive igneous pob zeb ' vim lawv tsim los ntawm 'extrusion,' los yog tawg, ntawm lava ab roob hluav taws . Plutonic pob zeb yog pob zeb tsim thaum magma txias thiab solidifies hauv qab lub ntiaj teb nto.
Ib sab ntawm no, koj yuav qhia li cas yog pob zeb yog volcanic lossis plutonic?
Plutonic pob zeb tseem coarser grained, yog ua los ntawm loj interlocking crystals whereas pob zeb volcanic yog zoo-grained. Volcanic pob zeb kuj tsim heev heev whereas lub tsim ntawm plutonic pob zeb yog qeeb dua.
Ib yam li ntawd, cov pob zeb plutonic tau mus rau saum npoo li cas? Plutonic pob zeb yog tsim thaum magma cools andsolidifies underground. Volcanic pob zeb yog tsim los ntawm lavathat ntws ntawm lub nto ntawm lub ntiaj teb thiab lwm cov ntiaj chaw thiab ces txias thiab solidifies. Kev ntxhib los mos ntawm ib qho igneous pob zeb nyob ntawm qhov luaj li cas ntawm cov muaju nyob rau hauv lub pob zeb.
Tsis tas li ntawd nug, dab tsi yog thawj txoj hauv kev kom paub qhov txawv volcanic thiab plutonic pob zeb?
Volcanic pob zeb yog nplua-grained thiab pom nyob rau hauv lub ntiaj teb no planetary lub cev nyob rau hauv peb lub hnub ci system. PLUTONICROCKS : Plutonic pob zeb yog igneous pob zeb uas tsim los ntawm subterranean chambers ntawm molten pob zeb lub magma. Plutonic pob zeb ua lub hauv paus ntawm continental crust li wellas oceanic crust.
Dab tsi yog 4 hom plutons?
Hauv kev xyaum lub sij hawm pluton feem ntau txhais tau hais tias anon-tabular igneous intrusive lub cev. Qhov feem ntau pob zeb hom hauv plutons yog granite, granite, tonalite, monzonite, thiab quartz diorite.

Dab tsi yog qhov txawv ntawm cov pob zeb tsis foliated thiab foliated metamorphic pob zeb?
Foliated metamorphic pob zeb xws li gneiss, phyllite, schist, thiab slate muaj ib txheej txheej los yog banded zoo li uas yog tsim los ntawm raug tshav kub thiab qhia siab. Non-foliated metamorphic pob zeb xws li hornfels, marble, quartzite, thiab novaculite tsis muaj txheej txheej lossis banded zoo li
Dab tsi yog qhov txawv ntawm pob zeb volcanic thiab plutonic?
Qhov no yog vim hais tias plutonic pob zeb yog pob zeb tsim thaum magma txias thiab solidifies hauv qab lub ntiaj teb nto, thiab volcanic pob zeb yog pob zeb tsim thaum lava txias thiab solidifies ntawm lub ntiaj teb nto
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi tuaj yeem sib txawv ntawm cov pob zeb sedimentary qhia geologists txog qhov chaw?
Ib qho outcrop uas muaj ob peb kab rov tav sedimentary pob zeb txheej sawv cev rau lub sij hawm ntsug-series ntawm geological txheej xwm. Cov textures ntawm txhua txheej sedimentary qhia peb txog ib puag ncig uas muaj nyob rau ntawm qhov chaw ntawd thaum txheej txheej tsim
Koj puas tuaj yeem muab cov pob zeb tso rau hauv pob zeb tumbler?
Feem ntau hom pob zeb tsis ua haujlwm zoo hauv pob zeb tumbler. Yog tias koj sib tov zoo tumbling ntxhib nrog pob zeb uas qis dua qib qis, cov khoom, cov npoo ntse thiab tawg ntawm cov khoom hauv qab-tumbling-qib tej zaum yuav ua rau cov polish ntawm txhua lub pob zeb hauv lub thoob
