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

Yuav nrhiav pom pob zeb nyob qhov twg?

Ntawm Igneous Rocks Found. Lub tob hiav txwv (cov dej hiav txwv crust) yog ua los ntawm cov pob zeb bas altic, nrog peridotite hauv qab hauv lub mantle. Bas alts kuj tau tawg nyob rau saum lub ntiaj teb qhov zoo subduction zones, txawm nyob rau hauv volcanic kob arcs los yog raws ntug ntawm continents.

pob zeb igneous feem ntau yog dab tsi thiab lawv feem ntau pom nyob qhov twg?
