  • Obsidian. Obsidian, tseem hu ua volcanic iav, cov ntaub ntawv thaum silica-nplua nuj magma txias yuav luag tam sim, feem ntau vim yog kev sib cuag nrog dej.
  • Andesite.
  • Dacite.
  • Rhyolite.
  • Pumice.
  • Scoria.
  • Komatiite.

Ua ke, cov qauv dab tsi tuaj yeem tsim los ntawm extrusive igneous pob zeb?

Extrusive igneous pob zeb tawg mus rau hauv nto , qhov chaw uas lawv txias sai heev los tsim cov muaju me me. Qee qhov txias sai sai uas lawv tsim lub iav amorphous. Cov pob zeb no muaj xws li andesite, basalt, dacite, obsidian, pumice, rhyolite, scoria, thiab tuff.

Ib tug kuj yuav nug, dab tsi yog cov khoom ntawm extrusive igneous pob zeb? Igneous pob zeb uas tsim los ntawm crystallization ntawm magma nyob rau saum npoo ntawm lub ntiaj teb hu ua extrusive pob zeb . Lawv yog cov yam ntxwv los ntawm cov nplua-grained textures vim tias lawv cov cua txias ceev ntawm lossis ze ntawm qhov chaw tsis muaj sijhawm txaus rau cov muaju loj loj tuaj.

Nyob rau hauv no hais txog, uas yog ib tug extrusive igneous pob zeb?

Extrusive igneous pob zeb daim ntawv thaum magma nce mus txog lub ntiaj teb nto volcano thiab txias sai sai. Feem ntau extrusive (volcanic) pob zeb muaj me me crystals. Piv txwv li basalt, rhyolite, andesite, thiab obsidian.

Dab tsi yog plaub hom pob zeb igneous?
