Qhov sib txawv ntawm pob zeb thiab pob zeb

kev taw qhia

Lub ntiaj teb yog tsim los ntawm ntau hom khoom, xws li cov huab cua, dej, cov kab mob nyob, tab sis feem ntau ntawm lub ntiaj teb loj muaj pob zeb thiab minerals. Ob lo lus feem ntau siv sib hloov, tab sis lawv puas yog tib yam? Hauv tsab xov xwm no peb yuav piav qhia qhov sib txawv ntawm pob zeb thiab pob zeb.

Cov minerals yog dab tsi?

lub cov zaub mov Lawv yog cov khoom ntuj tsim los ntawm cov txheej txheem geological. Lawv muaj cov tshuaj muaj pes tsawg leeg, cov qauv crystalline thiab cov khoom siv lub cev tshwj xeeb, xws li hardness, ntom thiab xim. Qee cov qauv Cov zaub mov muaj xws li quartz, feldspar, calcite thiab gypsum.

Cov khoom muaj ntxhia

• Lub npe: ntsuas qhov tsis kam ntawm ib qho ntxhia kom raug khawb.
• xim: Nws txawv nyob ntawm seb cov tshuaj muaj pes tsawg leeg ntawm cov ntxhia.
• Qhov ceev: kev sib raug zoo ntawm huab hwm coj thiab ntim ntawm ib tug ntxhia.
• Pob tshab: muaj peev xwm ntawm cov pob zeb hauv av kom tso cai rau qhov kev pom ntawm lub teeb.

Dab tsi yog pob zeb?

lub pob zeb, ntawm qhov tod tes, yog ntuj aggregates ntawm cov zaub mov lossis lwm yam khoom siv geological. Lawv tuaj yeem tsim los ntawm ib qho ntxhia lossis ntau cov ntxhia sib txawv, thiab tsim los ntawm cov txheej txheem geological xws li solidification ntawm magma lossis sedimentation ntawm cov khoom. Qee qhov piv txwv ntawm cov pob zeb ntau yog granite, slate, thiab marble.

Pob zeb hom

• Igneous: Lawv tsim los ntawm qhov txias thiab solidification ntawm magma los yog lava.
• Sedimentary: Lawv yog tsim los ntawm tsub zuj zuj thiab cementation ntawm sediments.
• Metamorphic: Lawv raug tsim los ntawm kev hloov pauv ntawm cov pob zeb ua ntej uas twb muaj lawm vim qhov kub thiab txias.

SIB THAM

Txawm hais tias cov ntsiab lus pob zeb thiab pob zeb hauv av qee zaum siv sib hloov, lawv yog ob yam sib txawv. Minerals yog cov khoom, cov khoom ntuj tsim nrog cov tshuaj muaj pes tsawg leeg thiab cov yam ntxwv ntawm lub cev, thaum cov pob zeb yog cov khoom sib xyaw ntawm cov ntxhia thiab lwm yam khoom siv geological uas tsim los ntawm cov txheej txheem geological. Kev nkag siab txog qhov sib txawv ntawm pob zeb thiab cov ntxhia pob zeb yog qhov tseem ceeb rau kev nkag siab txog kev tshawb fawb los ntawm lub ntiaj teb thiab yuav ua li cas cov ntaub ntawv geological tsim.
