Hauv ntiaj teb kev kawm , kev tawg hais txog yuav ua li cas qee cov zaub mov tawg raws lub dav hlau tiaj tus thaum raug kev nyuaj siab, xws li raug ntaus rauj. Cleavage tsim du, tiaj tus nto uas qhia txog lub teeb. Minerals uas tawg nyob rau hauv tsis xwm yeem, jagged los yog splintered npoo yog hais tias muaj pob txha.
Ib yam li ntawd, tib neeg nug, dab tsi yog tawg thiab cleavage?
Cleavage yog qhov nyiam ntawm cov pob zeb hauv av kom tawg raws cov dav hlau du thaum uas tig mus rau thaj chaw ntawm kev sib txuas tsis muaj zog. Kev tawg yog qhov nyiam ntawm cov pob zeb hauv av kom tawg raws cov npoo nkhaus yam tsis muaj cov duab meej. Cov zaub mov no tsis muaj dav hlau tsis muaj zog thiab tawg tsis tu ncua.
Tsis tas li ntawd, koj yuav nrhiav tau cleavage li cas? Cleavage . Cleavage piav qhia txog yuav ua li cas cov pob zeb tawg rau hauv qhov chaw tiaj tus (feem ntau yog ib, ob, peb lossis plaub qhov chaw). Cleavage yog txiav txim los ntawm cov qauv siv lead ua ntawm cov ntxhia. Cubic: Thaum lub pob zeb tawg hauv peb cov lus qhia thiab cov kev tawg cov dav hlau tsim cov kaum sab xis (90 degrees rau ib leeg).
Ib yam li ntawd, 3 lub dav hlau cleavage yog dab tsi?
Hom cleavage
- Basal lossis pinacoidal cleavage tshwm sim thaum tsuas muaj ib lub dav hlau cleavage xwb.
- Cubic cleavage tshwm sim thaum muaj peb lub dav hlau cleavage sib tshuam ntawm 90 degrees.
- Octahedral cleavage tshwm sim thaum muaj plaub lub dav hlau cleavage hauv ib lub siv lead ua.
Dab tsi yog cleavage property?
Cleavage txhais tau hais tias txiav ib yam dab tsi hauv ob lossis ntau qhov tseem ceeb, yog li nws yog a vaj tse uas ua rau cov khib nyiab cuttable los yog tawg tau yooj yim daim.

Dab tsi yog qhov txawv ntawm kev siv science thiab natural science?
Natural sciences cuam tshuam nrog lub ntiaj teb lub cev thiab suav nrog astronomy, biology, chemistry, geology, thiab physics. Applied science yog cov txheej txheem ntawm kev siv cov kev paub txog kev tshawb fawb rau cov teeb meem, thiab siv rau hauv kev lag luam xws li engineering, kev saib xyuas kev noj qab haus huv, kev siv technology, thiab kev kawm thaum yau
Kev sib raug zoo ntawm science thiab social science yog dab tsi?
Kev tshawb fawb (tseem hu ua ntshiab, ntuj, lossis kev tshawb fawb lub cev) thiab kev tshawb fawb txog kev sib raug zoo yog ob hom kev tshawb fawb uas cuam tshuam nrog tib cov qauv kev tshawb fawb thiab cov khoom ntawm lawv tus kheej txoj cai lij choj. Kev tshawb fawb muaj kev txhawj xeeb ntau dua nrog kev kawm xwm, thaum kev tshawb fawb txog tib neeg kev coj cwj pwm thiab kev sib raug zoo
Dab tsi yog qhov ntxhia cleavage nyob rau hauv plaub cov lus qhia?
Peb cov lus qhia cleavage: yog lawv sib tshuam ntawm 90˚ = cubic cleavage; yog cov ces kaum tsis yog 90˚ = rhombohedral. Minerals nrog 4 lossis 6 cleavages tsis yog ntau. Plaub lub dav hlau cleavage tuaj yeem tsim 8-sided duab = octahedral cleavage (piv txwv li, fluorite)
Dab tsi yog qhov txawv ntawm kev txiav txim siab cleavage radial cleavage thiab indeterminate cleavage?
Dab tsi yog qhov txawv ntawm indertermate thiab txiav txim cleavage? Indeterminate cleavage = deuterostomes(peb). radially cleave perpendicular rau polar axis. hlwb txoj hmoo tsis tau txiav txim ntxov rau
Dab tsi yog qhov txawv ntawm pob zeb cleavage thiab ntxhia cleavage?
RhombohedralThaum ib lub pob zeb tawg nyob rau hauv peb cov lus qhia thiab cov dav hlau cleavage tsim cov ces kaum uas yog lwm yam tshaj li 90 degrees. Cov duab tsim yog hu ua rhombohedron. Thaum cov pob zeb tawg hauv ib qho kev taw qhia, tawm hauv ib qho chaw tiaj tus (cleavage dav hlau)
