A lodestone yog ib tug lawm magnetized daim ntawm cov ntxhia magnetite . Lawv yog ib txwm tshwm sim hlau nplaum, uas tuaj yeem nyiam hlau. Magnetite yog xim av los yog xim av-dub, nrog ib tug hlau luster, ib tug Mohs hardness ntawm 5.5-6.5 thiab ib tug dub streak.
Hais txog qhov no, vim li cas magnetite hu ua Lodestone?
Magnetite raws li " Lodestone "Qhov no daim ntawv ntawm magnetite , lub npe hu ua " lodestone , " yog txiv neej thawj zaug ntsib nrog cov cuab yeej ntawm hlau nplaum. Lodestone yog yooj yim txheeb xyuas vim hais tias nws yog feem ntau them nrog me me hais ntawm magnetite thiab lwm yam khoom siv hlau nplaum (saib daim duab).
magnetite tsim li cas? Yog hais tias mafic magma cools qeeb txaus, ntom magnetite crystals yuav nyob twj ywm raws li lawv crystallize, tsim loj magnetite ore lub cev nrog ib tug muaj zog magnetic cim. Magnetite kuj tuaj yeem tsim thaum sib cuag metamorphism ntawm impure hlau - nplua nuj limestone, thiab nyob rau hauv high kub hydrothermal sulfide leeg deposits.
Ntawm no, qhov twg magnetite feem ntau pom?
Magnetite yog qee zaum pom nyob rau hauv qhov ntau ntawm cov xuab zeb puam. Xws li cov xuab zeb dub (mineral sands lossis hlau sands) yog pom nyob rau ntau qhov chaw, xws li Lung Kwu Tan ntawm Hong Kong; California, Tebchaws Asmeskas; thiab sab hnub poob ntug dej hiav txwv ntawm North Island of New Zealand.
Dab tsi yog magnetite siv hauv?
Magnetite yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob zoo li nws yog siv rau tsim hluav taws xob. Magnetite , vim nws cov khoom sib nqus, yog dav siv hauv compasss thiab lwm yam khoom siv navigation.

Puas yog liverwurst thiab daim siab cheese yog tib yam?
Tsis zoo li liverwurst, uas yog puag ncig, daim siab cheese yog square, thiab me ntsis muaj zog-tasting. Cov nqaij feem yog surrounded los ntawm ib tug nqaim band ntawm lard. Cov khoom xyaw tseem ceeb yog nqaij npuas siab, nqaij npuas, nqaij npuas rog, ntsev thiab dos rov ua dua
Puas yog kev xaiv ntuj yog tib yam li evolution?
Evolution thiab ' ciaj sia taus ntawm qhov fittest' tsis yog tib yam. Evolution yog hais txog cov kev hloov pauv hauv cov pejxeem lossis hom los ntawm lub sijhawm. 'Siv txoj sia nyob ntawm qhov fittest' yog ib lo lus nrov uas hais txog cov txheej txheem ntawm kev xaiv ntuj, ib qho kev hloov pauv hloov pauv hloov pauv
Puas yog lub zog gravitational ntawm ob yam khoom txaus nyiam los yog ob qho tib si?
Txij li thaum lub zog gravitational yog inversely proportional rau lub square ntawm kev sib cais nyob deb ntawm ob tug interacting khoom, ntau sib nrug deb yuav ua rau cov tsis muaj zog gravitational zog. Yog li thaum ob yam khoom sib cais los ntawm ib leeg, lub zog ntawm gravitational attraction ntawm lawv kuj txo
Puas yog cytosol thiab cytoplasm yog tib yam?
Lub cytoplasm yog tsim los ntawm cytosol thiab insoluble suspended hais. Lub cytosol hais txog cov dej thiab txhua yam uas yog soluble thiab yaj hauv nws xws li ions thiab soluble proteins. Cov insoluble suspended hais tuaj yeem yog yam zoo li ribosomes. Ua ke, lawv tsim cov cytoplasm
Puas yog qhov ntim thiab qhov chaw saum npoo yog tib yam?
Qhov txawv ntawm qhov chaw thiab ntim yog dab tsi? Qhov chaw saum npoo yog qhov sib npaug ntawm thaj chaw ntawm txhua lub ntsej muag ntawm daim duab khoom. Nws yog ntsuas nyob rau hauv square units. Volume yog tus naj npawb ntawm cubic units uas ua kom muaj ib daim duab
