Vim li cas qhov piv txwv tseem ceeb hauv kev lag luam zaub mov?
Kev kuaj cov zaub mov yog txheej txheem siv los xyuas tias cov khoom noj muaj kev nyab xeeb thiab tsis muaj cov kab mob phem, lossis nws tsuas muaj cov tshuaj ntxiv uas tau tso cai ntawm qib uas tau txais, lossis tias nws muaj cov qib zoo ntawm cov khoom xyaw tseem ceeb thiab nws cov ntawv tshaj tawm yog raug, los yog kom paub cov qib ntawm cov as-ham tam sim no
Dab tsi yog qhov tseem ceeb ntawm kev siv cov zaub mov?
Kev siv cov zaub mov. Cov ntxhia zoo li tooj liab yog siv hauv cov khoom siv hluav taws xob vim nws yog cov khoom siv hluav taws xob zoo. Av nplaum yog siv los ua cov cement thiab lwm yam uas pab tsim txoj kev. Fiberglass, tshuaj ntxuav yog tsim los ntawm borax
Puas yog hlau ua los ntawm cov zaub mov?
Cov hlau yog inorganic thiab feem ntau muaj cov qauv crystalline thiab yog cov khoom. Txhua yam koj xav tau yog rau cov hlau ntawd tshwm sim ntawm nws tus kheej daim ntawv rau nws ua ib qho ntxhia. Txawm li cas los xij, muaj cov xwm txheej uas cov hlau, ib txwm muaj hlau tau pom, feem ntau hauv cov meteorites, yog li Hlau yog cov ntxhia
Cov khoom siv tshuaj lom neeg ntawm cov zaub mov yog dab tsi?
Cov khoom uas pab geologists txheeb xyuas cov pob zeb hauv pob zeb yog: xim, hardness, luster, crystal forms, ntom, thiab cleavage. Crystal form, cleavage, thiab hardness yog txiav txim siab feem ntau los ntawm cov qauv siv lead ua ntawm qib atomic. Xim thiab ntom yog txiav txim siab feem ntau los ntawm cov tshuaj muaj pes tsawg leeg
Dab tsi yog qhov txawv ntawm lub cev thiab tshuaj lom neeg ntawm cov zaub mov?
Minerals raug cais raws li lawv cov tshuaj muaj pes tsawg leeg, uas tau qhia hauv lawv lub cev. Cov qauv no, qhov thib ob hauv cov kab hauv cov ntxhia, piav qhia txog lub cev lub zog uas feem ntau siv los txheeb xyuas cov zaub mov. Cov no muaj xws li xim, crystal form, hardness, ntom, luster, thiab cleavage
