Peb cov lus qhia cleavage: yog lawv sib tshuam ntawm 90˚ = cubic cleavage; yog tias 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).
Ib yam li ntawd, tej zaum koj yuav nug, dab tsi ntxhia cleaves nyob rau hauv plaub cov lus qhia?
Ob lub dav hlau cleavage hauv gypsum sib tshuam ntawm 90 °, qhov thib peb tsis. Cov ntxhia nrog plaub los yog rau cleavage cov lus qhia tsis muaj ntau. Plaub cleavage dav hlau tuaj yeem hla los ua ib daim duab yim sab hu ua octahedron (Daim duab 12). Fluorite yog feem ntau ntxhia nrog octahedral cleavage.
Yuav ua li cas minerals tsim cleavage? Hauv ntxhia cov ntsiab lus, cleavage piav qhia txog yuav ua li cas lub pob zeb tawg thaum muaj kev ntxhov siab ntawm ib lub dav hlau tshwj xeeb. Yog hais tias ib feem ntawm cov siv lead ua tawg vim muaj kev ntxhov siab thiab cov khoom tawg tau khaws lub dav hlau du lossis siv lead ua zoo li qub, lub ntxhia muaj cleavage.
Khaws qhov no hauv kev xav, dab tsi yog qhov cleavage ntawm cov ntxhia?
Cleavage yog qhov nyiam ntawm a ntxhia txhawm rau ua kom cov dav hlau du sib npaug mus rau thaj chaw ntawm kev sib txuas tsis muaj zog. Fracture yog qhov nyiam ntawm a ntxhia kom tawg raws nkhaus nto yam tsis muaj cov duab meej. Cov no cov ntxhia tsis muaj cov dav hlau tsis muaj zog thiab tawg irregularly.
Dab tsi mineral muaj hardness ntawm 7?
quartz

Lub ntsiab lus ntawm lub hauv paus lo lus meter nyob rau hauv lo lus tus pas ntsuas kub yog dab tsi?
Lub hauv paus chiv keeb ntawm lo lus 'Thermometer' Qhov thib ob ntawm lo lus, 'meter', los ntawm Fabkis -mètre (uas muaj nws cov hauv paus hauv lub post-classical Latin: -meter, -metrumand lub ancient Greek, -Μέτρο ν, lossis metron, uas txhais tau tias ntsuas qee yam, xws li qhov ntev, qhov hnyav, lossis dav)
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
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
Qhov twg ntawm cov plaub hau plaub hau yog ib txwm plaub hau plaub hau?
square Tsis tas li ntawd nug, qhov ntsuas ntawm ib lub quadrilateral tsis tu ncua yog dab tsi? Yog, sab hauv lub kaum sab xis ntawm txhua lub ces kaum ntawm ib lub quadrilateral tsis tu ncua yog txhua 90 degrees (360 degrees / 4 fab).
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)
