Lub sij hawm los ntawm FEL rau feldspar (qhov no yog cov poov tshuaj-nplua nuj ntau yam) thiab SIC, uas qhia txog siab dua feem pua ntawm silica . Felsic cov ntxhia yog feem ntau lub teeb nyob rau hauv cov xim thiab muaj tshwj xeeb gravities tsawg dua 3.0. Feem ntau felsic Cov zaub mov muaj xws li quartz, muscovite mica, thiab orthoclase feldspars.
Tib neeg kuj nug, cov pob zeb mafic felsic puas muaj silica ntau dua?
Mafic lava tsim basalt thaum felsic lava tsim andesitic thiab rhyolite pob zeb . 5. Los ntawm kev piav qhia pob zeb lub lava, mafic txhais hais tias lub lava los yog pob zeb muaj tsawg silica thaum felsic implies tias lava los yog pob zeb muaj tus feem ntau silica.
Qhov thib ob, hom pob zeb uas tsis muaj zog yuav muaj cov silica ntau tshaj? Felsic igneous pob zeb
Ib yam li ntawd, lub pob zeb twg muaj pes tsawg leeg ntawm silica?
Compilations ntau pob zeb kev soj ntsuam qhia tias rhyolite thiab granite yog felsic, nrog rau qhov nruab nrab silica cov ntsiab lus ntawm kwv yees li 72 feem pua; syenite, diorite, thiab monzonite yog nruab nrab, nrog rau qhov nruab nrab silica cov ntsiab lus ntawm 59 feem pua; gabbro thiab basalt yog mafic, nrog rau qhov nruab nrab silica cov ntsiab lus ntawm 48 feem pua; thiab peridotite yog
Dab tsi yog felsic pob zeb siab?
Hauv geology, felsic yog ib qho kev piav qhia igneous pob zeb uas kuj nplua nuj nyob rau hauv cov ntsiab lus uas tsim feldspar thiab quartz. Nws yog contrasted nrog mafic pob zeb, uas kuj nplua nuj nyob rau hauv magnesium thiab hlau.

Dab tsi Magma muaj cov ntsiab lus silica siab tshaj?
MAGMA COMPOSITION THIAB ROCK HOM SiO2 COV NTAUB NTAWV MAGMA HOM VOLCANIC ROCK ~ 50% Mafic Basalt ~ 60% Intermediate Andesite ~ 65% Felsic (tsawg Si) Dacite ~ 70% Felsic (siab Si) Rhyolite
Puas muaj zog hauv paus muaj pH siab?
Zoo li muaj zog acids, lub hauv paus muaj zog dissociates yuav luag tag nrho hauv dej; Txawm li cas los xij, nws tso tawm hydroxide (OH-) ions ntau dua li H +. Cov hauv paus muaj zog muaj pH siab heev, feem ntau yog li 12 txog 14
Muaj pes tsawg guanine bases puas yog 50 lub hauv paus khub ob txoj hlua DNA 100 bases tag nrho muaj yog tias nws muaj 25 adenine bases?
Yog li, muaj tag nrho ntawm 25 + 25 = 50 adenine thiab thymine hauv tag nrho. Qhov ntawd tawm 100− 50 = 50 seem hauv paus. Nco ntsoov tias cytosine thiab guanine daim ntawv cog lus nrog ib leeg, thiab yog li lawv sib npaug ntawm cov nyiaj. Tam sim no peb tuaj yeem faib los ntawm 2 kom tau txais tus lej ntawm guanine lossis cytosine hauv paus
Hom pob zeb twg muaj cov ntsiab lus silica siab tshaj?
Felsic pob zeb, siab tshaj cov ntsiab lus ntawm silicon, nrog predominance ntawm quartz, alkali feldspar thiab / los yog feldspathoids: felsic minerals; Cov pob zeb no (piv txwv li, granite, rhyolite) feem ntau yog xim xim, thiab muaj qhov ntom ntom
Puas yog slant qhov siab tib yam li qhov siab?
Qhov siab ntsug (los yog qhov siab) uas yog qhov kev ncua deb ntawm sab saum toj mus rau hauv paus. Qhov siab slant uas yog qhov kev ncua deb ntawm sab saum toj, hauv qab, mus rau ib qho taw tes ntawm lub hauv paus ncig
