Pahoehoe lava yog du thiab tuaj yeem muaj ropy, billowy tsos. Nws tsis tshua muaj viscosity, qhov ntsuas ntawm cov kua tuab, thiab feem ntau txav mus qeeb.
pahoehoe puas yog viscosity?
Viscosity yog cov kua dej tsis kam ntws. … Lwm hom bas altic ntws yog pahoehoe (hais tias pa-hoy-hoy). Pahoehoe thiab aa muaj cov tshuaj tib yam txawm hais tias pahoehoe tsawg dua(kua ntau dua) ces aa vim cov pa roj tseem tsis tau khiav tawm. Pahoehoe lava ntws tau du, ropy nto.
Puas yog pahoehoe kua heev?
Pahoehoe (lo lus yog Hawaiian rau ropy) lava yog lo lus rau txias textures ntawm cov kua dej, roj-them lava ntwsthiab tau qhia raws li cov lus qhia los ntawm Clarance Dutton, ib., 1883. Qhov saum npoo ntawm Pahoehoe lava feem ntau yog du, undulant, lossis ropy (Daim duab 1). Cov textures no yog tsim los ntawm deformation ntawm ntws.
Puas pahoehoe lava tuab?
Lava ntws mus rau hiav txwv los ntawm lub roob hluav taws Kilauea, Hawaii, siv ob hom kev paub: nrawm nrawm, ropy lava, hu ua pahoehoe, thiab tuab, blocky lava, hu ua aa.
Puas yog pahoehoe lava mafic lossis felsic?
Mafic lava, uas tsim ntau ntawm dej hiav txwv crust, muaj magnesium thiab hlau. Mafic lava yog lub luag haujlwm tseem ceeb rau kev tsim cov Islands tuaj Hawaii. Ob hom ntawm mafic lava ntws tau paub los ntawm lawv lub npe Hawaiian: pahoehoe thiab aa. Pahoehoe lava yog billowy lava uas feem ntau wrinkled thiab ropy nyob rau hauv tsos.

Puas yog viscosity yog rheological khoom?
Cov kev ntsuas rheological yog viscosity (cp), torque%, shear stress (dyne/cm 2 ) thiab shear rate (s - 1). Dab tsi yog qhov txawv ntawm rheology thiab viscosity? Qhov sib txawv tseem ceeb ntawm rheology thiab viscosity yog qhov rheology yog kev kawm txog qhov ntws ntawm cov teeb meem, whereas viscosity yog ib qho kev ntsuas ntawm nws qhov tsis kam mus deformation.
Cov concentration puas cuam tshuam rau viscosity?
Tus nqi viscosity ntawm qhov muab cov concentration ua raws H > A > G > E. Ib qho nce hauv cov kua dej ntau ntxiv yuav ua rau muaj qhov nce ntxiv, tsuas yog vim xav tau lub zog ntxiv los txhais lossis tig cov molecules hauv kev daws .
Puas tau them daim siab mob siab rau lub siab?
Compensated: Thaum koj tsis muaj cov tsos mob ntawm tus kab mob, koj raug txiav txim siab tias koj tau them nyiaj cirrhosis Decompensated: Thaum koj tus mob cirrhosis tau nce mus rau lub siab. tab tom muaj teeb meem ua haujlwm thiab koj pib muaj cov tsos mob ntawm tus kab mob, koj raug txiav txim siab tias muaj decompensated cirrhosis .
Puas thaiv hluav taws xob muaj viscosity siab?
Shield volcanoes yog tsim los ntawm yuav luag tag nrho cov lava uas nyias nyias ua los ntawm lub hauv paus qhov cua. Feem ntau cov ntaub thaiv npog tau tsim los ntawm qis viscosity bas alticmagma uas ntws yooj yim nqes nqes deb ntawm qhov ua siab tshaj qhov cua .
Puas viscosity nyob ntawm qhov siab?
Viscosity feem ntau yog ywj siab ntawm siab, tab sis cov kua dej nyob rau hauv siab heev feem ntau muaj kev nce hauv viscosity. Txij li thaum cov kua dej ib txwm tsis muaj kev sib txuas, qhov nce hauv siab tsis tshua coj cov molecules los ze zog ua ke .
