Igneous, Sedimentary, thiab Metamorphic. Igneous pob zeb yog tsim los ntawm cov pob zeb yaj hauv qhov tob hauv ntiaj teb. Cov pob zeb sedimentary yog tsim los ntawm txheej ntawm cov xuab zeb, silt, cov nroj tsuag tuag, thiab cov pob txha tsiaj. Cov pob zeb metamorphic tsim los ntawm lwm cov pob zeb uas hloov los ntawm tshav kub thiab siab hauv av.
3 pob zeb yog dab tsi thiab lawv tsim li cas?
Muaj peb hom pob zeb: igneous, sedimentary, thiab metamorphic. Igneous pob zeb tsim thaum molten pob zeb (magma los yog lava) txias thiab solidifies. Cov pob zeb sedimentary originates thaum hais tawm ntawm dej los yog huab cua, los yog los ntawm nag lossis daus ntawm minerals los ntawm dej. Lawv sib sau ua ke.
Dab tsi yog qhov igneous metamorphic thiab sedimentary pob zeb muab piv txwv ntawm lawv?
Piv txwv suav nrog sandstone, thee thiab chalk. Qee cov pob zeb sedimentary muaj cov pob txha (cov pob txha lossis cov plhaub ntawm cov khoom muaj sia uas tau faus ntev dhau los thiab tau tig mus rau pob zeb). Cov pob zeb metamorphic yog tsim thaum lwm cov pob zeb hloov pauv vim yog cua sov lossis siab. Piv txwv suav nrog slate thiab marble.
Yuav ua li cas yog cov yam ntxwv ntawm igneous sedimentary thiab metamorphic pob zeb?
Igneous - lawv tsim los ntawm qhov txias ntawm magma tob rau hauv lub ntiaj teb. Lawv feem ntau muaj cov muaju loj (koj tuaj yeem pom lawv ntawm qhov muag liab qab). Metamorphic - lawv yog tsim los ntawm kev hloov pauv (metamorphosis) ntawm cov pob zeb tsis zoo thiab cov pob zeb sedimentary. Lawv tuaj yeem tsim hauv av thiab hauvnto.
3 hom pob zeb tseem ceeb yog dab tsi?
Thaum molten rock , los yog melted rock , solidifies, igneous rocks yog tsim. Muaj ob yam hom pob zeb igneous : intrusive thiab extrusive.
- andesite.
- bas alt.
- dacite.
- obsidian.
- pumice.
