Intrusive igneous pob zeb crystallize hauv qab lub ntiaj teb saum npoo, thiab qhov txias qeeb uas tshwm sim muaj tso cai rau cov muaju loj tsim. Piv txwv ntawm intrusive igneous pob zeb yog diorite , gabbro ua , granite, pegmatite, thiab peridotite . Extrusive igneous pob zeb tawg mus rau saum npoo, qhov chaw uas lawv txias sai sai rau cov pob zeb me me.

Tsis tas li ntawd, qhov twg yog pob zeb tsis muaj pob zeb?

Feem ntau hom pob zeb igneous yog:

  • andesite.
  • basalt.
  • dacite.
  • dolerite (tseem hu ua diabase)
  • gabbro ua.
  • diorite.
  • peridotite.
  • neej.

Tsis tas li ntawd, igneous rock luv teb yog dab tsi? Igneous pob zeb yog pob zeb tsim los ntawm molten magma. Cov khoom yog ua kua los ntawm tshav kub nyob rau hauv lub ntiaj teb lub mantle. Thaum magma tawm mus rau saum npoo ntawm lub ntiaj teb, nws hu ua lava. Lava txias mus rau hauv daim ntawv pob zeb xws li tuff thiab basalt.

Kuv yuav nrhiav tau pob zeb uas tsis muaj zog nyob qhov twg?

Igneous pob zeb daim ntawv thaum magma (molten pob zeb ) cools thiab crystallizes, txawm nyob rau ntawm volcanoes nyob rau saum npoo ntawm lub ntiaj teb los yog thaum lub melted pob zeb tseem nyob rau hauv lub crust. Tag nrho cov magma tsim nyob rau hauv av, nyob rau hauv qis crust los yog sab sauv mantle, vim hais tias ntawm lub kub kub nyob rau ntawd.

Dab tsi yog 2 hom pob zeb igneous?

Igneous pob zeb yog tsim los ntawm lava los yog magma. Magma yog molten pob zeb uas yog underground thiab lava yog molten pob zeb uas erupts tawm ntawm qhov chaw. Cov ob lub ntsiab hom pob zeb igneous yog plutonic pob zeb thiab pob zeb volcanic . Plutonic pob zeb yog tsim thaum magma txias thiab solidifies underground.
