Txheej peridotites yog igneous sediments thiab daim ntawv los ntawm mechanical tsub zuj zuj ntawm ntom olivine crystals. Ib txhia peridotite Cov ntaub ntawv los ntawm nag lossis daus thiab sib sau ua ke ntawm olivine thiab pyroxene los ntawm mantle-derived magmas, xws li cov basalt muaj pes tsawg leeg.
Xav txog qhov no, dab tsi yog peridotite siv rau?
Peridotites yog cov pob zeb tseem ceeb ntawm kev lag luam vim lawv feem ntau muaj chromite - tsuas yog ore ntawm chromium; lawv tuaj yeem ua pob zeb rau pob zeb diamond; thiab, lawv muaj peev xwm ua tau siv li ib qho khoom siv rau kev nqus cov pa roj carbon dioxide.
Tom qab ntawd, lo lus nug yog, qhov peridotite zoo li cas? Peridotite yog ib tug heev ntom, coarse-grained, olivine-nplua nuj, ultra-mafic intrusive pob zeb. Nws tau sau tseg rau nws cov ntsiab lus silica tsawg, thiab muaj tsawg heev lossis tsis muaj feldspar (orthoclase, plagioclase).
Ib sab saum toj no, puas yog peridotite intrusive lossis extrusive?
Intrusive Cov pob zeb igneous crystallize hauv qab lub ntiaj teb saum npoo, thiab qhov txias qeeb uas tshwm sim muaj tso cai rau cov pob zeb loj tuaj. Piv txwv ntawm cuam tshuam Cov pob zeb igneous yog diorite, gabbro, granite, pegmatite, thiab peridotite . Extrusive igneous pob zeb tawg mus rau saum npoo, qhov chaw uas lawv txias sai sai los ua cov muaju me me.
Puas yog peridotite yog basaltic?
Nws yog lub hauv paus pob zeb ntawm basalt . Basaltic magma daim ntawv thaum peridotite yog ib nrab yaj. Basalt thiab peridotite txawv nyob rau hauv muaj pes tsawg leeg vim pob zeb yog mixs ntawm minerals, tab sis txhua pob zeb muaj nws tus kheej melting kub.

Dab tsi yog qhov cuab yeej tsim nyog ua ntej kev tshawb xav ntawm tes yuav tsim tau?
Lub microscope yog tsim nyog ua ntej qhov kev xav ntawm tes yuav tsim. Peb tus kws tshawb fawb twg tau txais qhab nia rau cov pov thawj ncaj qha ua rau txoj kev xav ntawm tes? Matthias Schleiden, Theodor Schwann, thiab Rudolph Virchow peb yog txhua tus kws tshawb fawb uas tau pab txhawb txoj kev xav ntawm tes
Yuav ua li cas compound yuav tsim yog Aluminium thiab oxygen tau ua ke?
Aluminium tuaj yeem hnov mob nrog cov pa oxygen los tsim cov txhuas oxide (Al_2O_3)
Lub chaw tsim hluav taws xob nuclear tsim tau li cas?
Nuclear fission tsim cua sov Reactors siv uranium rau nuclear roj. Cov uranium tau ua tiav rau hauv cov me me ceramic pellets thiab muab tso ua ke rau hauv cov raj hlau kaw hu ua roj rods. Lub tshav kub tsim los ntawm fission hloov cov dej mus rau hauv chav, uas tig lub turbine los tsim hluav taws xob tsis muaj carbon
Yuav ua li cas muaj pes tsawg tus tooj liab atoms koj yuav tsum tau kab ntawm ib sab los tsim ib kab 1'm ntev?
Los ntawm kev sib piv, lub ntiaj teb cov pej xeem tsuas yog hais txog 7? 109 neeg. Yog tias koj tuaj yeem ua kab 100,000,000 tooj liab atoms ib sab, lawv yuav tsim ib txoj kab ntev li 1 cm
Yuav ua li cas yuav tsum tshwm sim rau electrons los tsim spectral kab?
Thaum cov electrons txav los ntawm qib siab zog mus rau qis dua, photons raug tso tawm, thiab cov kab hluav taws xob tuaj yeem pom hauv spectrum. Cov kab nqus tau pom thaum electrons nqus photons thiab txav mus rau qib siab zog. Yog hais tias lub atom tau poob ib los yog ntau dua electrons, nws yog hu ua ion thiab hais tias yuav ionized
