Basalt . Basalt yog a Feem ntau cov pob zeb uas muaj xim daj-xim av uas muaj calcic plagioclase (feem ntau yog labradorite), clinopyroxene (augite) thiab hlau ore (titaniferous magnetite). Basalt kuj tseem muaj olivine, quartz, hornblende, nepheline, orthopyroxene, thiab lwm yam. Basalt yog a volcanic sib npaug ntawm gabbro.
Hais txog qhov no, dab tsi cov zaub mov muaj nyob hauv Basalt?
Lub mineralogy ntawm basalt yog yus muaj los ntawm ib tug preponderance ntawm calcic plagioclase feldspar thiab pyroxene . Olivine kuj tseem tuaj yeem yog qhov tseem ceeb. Accessory minerals tam sim no nyob rau hauv cov me me muaj xws li hlau oxides thiab hlau- titanium oxides, xws li magnetite, ulvöspinel, thiab ilmenite.
Ib yam li ntawd, puas yog Basalt ntawm lub rooj zaum? Strontium nyob rau hauv igneous pob zeb. Strontium (cim Sr, atomic naj npawb 38) occupies tib pab pawg nyob rau hauv lub Lub Sijhawm Sijhawm raws li qhov loj keeb Ca. Hauv feem ntau basalts , Sr cov ntsiab lus feem ntau yog li ntawm 100 txog 1000 ppm.
Ib yam li ntawd, basalt ua li cas?
Basalt yog ib qho extrusive igneous pob zeb uas yog xim dub heev. Basalt Cov ntaub ntawv thaum lava ncav cuag lub ntiaj teb saum npoo ntawm lub roob hluav taws lossis nruab nrab dej hiav txwv ridge. Lub lava yog nyob nruab nrab ntawm 1100 txog 1250 ° C thaum nws nkag mus rau saum npoo. Nws txias sai sai, tsis pub dhau ob peb hnub lossis ob peb lub lis piam, tsim cov pob zeb.
Cov ntsiab lus dab tsi ua magma?
99% ntawm cov magma muab los ntawm 10 lub ntsiab, suav nrog Silicon (Si), Titanium (Ti), Aluminium (Al), Hlau (Fe), Magnesium (Mg), Calcium (Ca), Sodium (Na), Potassium (K), Hydrogen (H) thiab Oxygen (O). Nyob rau hauv ib tug magma, lub ntuj lub xeev ntawm affairs yog rau tag nrho cov ntawm no hais kom muaj nyob rau hauv raws li hluav taws xob ions.

Dab tsi ua rau cov kab hauv emission spectrum rau cov ntsiab lus?
Cov kab hluav taws xob tshwm sim thaum cov hluav taws xob ntawm cov atom zoo siab, cov khoom lossis cov molecule txav ntawm qib zog, rov qab mus rau hauv av. Cov kab spectral ntawm ib lub caij tshwj xeeb lossis molecule ntawm so hauv chav kuaj ib txwm tshwm sim ntawm tib lub wavelengths
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 lub ntsiab lus ntawm kev hloov pauv lom neeg hauv cov ntsiab lus ntawm allele zaus?
Microevolution, los yog evolution ntawm ib tug me me, yog txhais raws li ib tug kev hloov nyob rau hauv lub zaus ntawm noob variants, alleles, nyob rau hauv ib tug pej xeem ntau tiam. Lub teb ntawm biology uas kawm txog allele frequencies nyob rau hauv cov pejxeem thiab yuav ua li cas lawv hloov lub sij hawm yog hu ua pej xeem noob caj noob ces
Vim li cas cov ntsiab lus thiab cov ntsiab lus yog cov tshuaj ntshiab?
Elements thiab compounds yog ob qho tib si piv txwv ntawm cov khoom ntshiab. Ib yam khoom uas tuaj yeem tawg mus rau hauv cov tshuaj lom neeg yooj yim dua (vim tias nws muaj ntau dua ib qho) yog ib qho khoom sib xyaw. Piv txwv li, dej yog acompound tsim los ntawm cov ntsiab lus hydrogen thiaboxygen
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
