Cov av tuaj yeem ua los ntawm cov khoom siv organic (tsiaj thiab nroj tsuag), inorganic (grains of rock) Cheebtsam, thiab dej. Cov khoom siv pob zeb eroded tuaj yeem muab tso rau hauv cov khaubncaws sab nraud povtseg los tsim sedimentary pob zeb , xws li sandstone, limestone thiab av nkos.
Tsuas yog li ntawd, hom av twg muaj igneous pob zeb?
Muaj peb hom pob zeb hauv ntiaj teb thiab plaub hom av yooj yim
- Igneous. Igneous pob zeb tsim ncaj qha los ntawm cua txias ntawm magma los ntawm sab hauv lub ntiaj teb.
- Sedimentary. Sedimentary pob zeb yog suav tias yog "secondary" pob zeb vim lawv feem ntau yog ua los ntawm lwm cov pob zeb.
- Metamorphic.
- Xuab zeb.
- Av nplaum.
- Silt.
- Loam.
Ib yam li ntawd, qhov sib txawv ntawm cov av thiab pob zeb yog dab tsi? Av thiab pob zeb yog tsim los ntawm cov ntaub ntawv zoo sib xws, tab sis txawv ntawm lawv cov qauv. Pob zeb (hauv qhov piv txwv no loj loj bedrock lossis ntab pob zeb formations) muaj cov cuab yeej txhais los ntawm qhov uas twb muaj lawm tsis ua hauj lwm nto - xws li tawg hauv pob zeb tsim. Av , ntawm qhov tod tes, muaj weathered pob zeb cov khoom.
Ib sab saum toj no, puas yog av tsim los ntawm pob zeb?
Av yog txheej nyias ntawm cov ntaub ntawv npog lub ntiaj teb nto thiab yog tsim los ntawm huab cua ntawm pob zeb . Nws yog ua nce feem ntau ntawm cov ntxhia hais, cov khoom siv organic, huab cua, dej thiab cov kab mob muaj sia nyob - tag nrho cov uas cuam tshuam qeeb tsis tas li.
Kev kawm ntawm pob zeb thiab av yog dab tsi?

Dab tsi yog qhov txawv ntawm cov pob zeb tsis foliated thiab foliated metamorphic pob zeb?
Foliated metamorphic pob zeb xws li gneiss, phyllite, schist, thiab slate muaj ib txheej txheej los yog banded zoo li uas yog tsim los ntawm raug tshav kub thiab qhia siab. Non-foliated metamorphic pob zeb xws li hornfels, marble, quartzite, thiab novaculite tsis muaj txheej txheej lossis banded zoo li
Lub pob zeb twg loj dua pob zeb?
Sedimentary pob zeb tuaj yeem ua los ntawm cobbles. Cobbles yog pob zeb uas loj dua pebbles tab sis me dua pob zeb. Conglomerate thiab breccia yog
Koj puas tuaj yeem muab cov pob zeb tso rau hauv pob zeb tumbler?
Feem ntau hom pob zeb tsis ua haujlwm zoo hauv pob zeb tumbler. Yog tias koj sib tov zoo tumbling ntxhib nrog pob zeb uas qis dua qib qis, cov khoom, cov npoo ntse thiab tawg ntawm cov khoom hauv qab-tumbling-qib tej zaum yuav ua rau cov polish ntawm txhua lub pob zeb hauv lub thoob
Yuav ua li cas lub pob zeb sedimentary ua ib lub pob zeb metamorphic?
Sedimentary pob zeb ua metamorphic nyob rau hauv lub pob zeb voj voog thaum lawv raug tshav kub thiab siab los ntawm faus. Cov kub kub yog tsim thaum lub ntiaj teb daim hlau tectonic txav ib ncig, ua kom sov. Thiab thaum lawv sib tsoo, lawv tsim roob thiab metamorphose
Cov pob zeb hauv av twg tuaj yeem tsim cov pob zeb zoo li lub raum?
Hematite (los yog haematite) Kuj tseem muaj ntau hom hematite, qee yam yog: raum ore, ib qho loj, botryoidal (lumpy) lossis reniform (lub raum zoo li tus) daim ntawv; specularite, micaceous (flaky) daim ntawv; oolitic, ib daim ntawv sedimentary tsim los ntawm cov nplej me me; liab ochre, ib daim ntawv liab earthy
