Cov kws tshawb fawb tau txheeb xyuas ntau dua 4,000 cov ntxhia nyob rau hauv lub ntiaj teb crust. A ntxhia yog crystalline khoom tsim los ntawm cov txheej txheem ntuj. A ntxhia tuaj yeem yog cov khoom lossis cov khoom sib xyaw, tab sis nws muaj cov tshuaj lom neeg tshwj xeeb thiab lub cev muaj zog uas txawv ntawm lwm yam cov ntxhia.
Yog li ntawd, dab tsi yog ib tug mineral scientific txhais?
"A ntxhia yog ib qho khoom siv lossis tshuaj lom neeg uas ib txwm muaj crystalline thiab tau tsim los ntawm cov txheej txheem geological" (Nickel, E. H., 1995). " Cov ntxhia yog ib txwm tshwm sim-tshwm sim inorganic tshuaj nrog ib tug meej thiab kwv yees tshuaj muaj pes tsawg leeg thiab lub cev muaj zog." (O' Donoghue, 1990).
Cov piv txwv ntawm cov zaub mov yog dab tsi? Piv txwv ntawm cov zaub mov yog feldspar, quartz, mica, halite, calcite, thiab amphibole.
Dab tsi yog cov ntxhia yooj yim txhais?
Cov ntxhia yog cov khoom uas raug tsim nyob rau hauv lub ntiaj teb. Cov ntxhia feem ntau yog cov khoom, inorganic, muaj cov qauv siv lead ua, thiab tsim los ntawm cov txheej txheem geological. Kev kawm ntawm cov ntxhia hu ua mineralogy. A ntxhia tuaj yeem ua los ntawm cov khoom siv tshuaj ib leeg lossis ntau dua ib qho kev sib xyaw.
Dab tsi yog qhov zoo tshaj plaws txhais ntawm cov ntxhia?
ib txwm tshwm sim, inorganic, khoom nrog kev sib koom ua ke ntawm cov atoms, thiab cov tshuaj muaj pes tsawg leeg.

Dab tsi yog txhais los ntawm lo lus inorganic hauv lub ntsiab lus ntawm cov ntxhia?
Ib txwm tshwm sim, homogeneous inorganic khoom muaj cov tshuaj muaj pes tsawg leeg thiab cov yam ntxwv crystalline qauv, xim, thiab hardness. Ib qho khoom siv tsis zoo, xws li calcium, hlau, potassium, sodium, lossis zinc, uas yog qhov tseem ceeb rau kev noj haus ntawm tib neeg, tsiaj txhu, thiab nroj tsuag
Dab tsi yog cov ntxhia ntau tshaj plaws hauv lithosphere?
Rau tus neeg nruab nrab, txawm tias qhov nruab nrab rockhound, feldspar zoo nkauj npaum li qub txawm nws ntog nyob rau qhov twg. Tsis tas li ntawd, xav txog tias cov pob zeb ntawm ntug hiav txwv dej, dej hiav txwv crust, yuav luag tsis muaj quartz txhua, tab sis muaj ntau ntawm feldspar. Yog li nyob rau hauv lub ntiaj teb crust, feldspar yog cov ntxhia tshaj plaws
Dab tsi yog lub hauv paus ntawm feem ntau yaj cov ntxhia hauv dej hiav txwv?
Dissolved los ntawm kev xyaum tag nrho cov khib nyiab thiab pob zeb, tab sis tshwj xeeb tshaj yog los ntawm limestone, dolomite, thiab gypsum, calcium (Ca) thiab magnesium (Mg) muaj nyob rau hauv ntau ntau nyob rau hauv ib co brines.Magnesium yog tam sim no nyob rau hauv loj ntau nyob rau hauv dej hiav txwv dej. Nws ua rau feem ntau ntawm hardness thiab scale-forming zog ntawm dej
Dab tsi yog ib qho kev qhia uas muaj tsawg kawg yog ib qho kev sib txawv?
Algebraic qhia ?: Cov lus lej suav nrog tsawg kawg ib qho sib txawv thiab qee zaum tus lej thiab cov cim ua haujlwm
Dab tsi yog ib qho reactant thiab khoom hauv science?
Reactants thiab cov khoom lag luam hauv tshuaj lom neeg. Ina tshuaj tiv thaiv, tshuaj (cov ntsiab lus thiab / los yog cov tebchaw) hu ua reactants raug hloov mus rau lwm yam khoom (compoundsand / los yog cov khoom) hu ua cov khoom. Koj tsis tuaj yeem hloov ib qho mus rau lwm qhov hauv cov tshuaj tiv thaiv tshuaj - uas tshwm sim innuclear cov tshuaj tiv thaiv
