Spheroidal thiab spindle-puab foob pob muaj ntau ntawm cinder cones . Tsis zoo li qhov hnyav heev tawg uas tsim loj stratovolcanoes, cinder cones form thaum qis- viscosity lava nrog ntau cov roj erupts, feem ntau raws li cov dej ntws. Lava tej zaum yuav spewed pua pua ntawm cov huab cua.
Xav txog qhov no, puas cinder cone volcanoes muaj viscosity siab?
Siab viscosity magmas tsim cinder cones thiab stratovolcanos, uas muaj Sab sab vim lawv cov extrusives solidify sai sai thaum lawv ncav cuag qhov chaw thiab txav deb ntawm lawv qhov chaw nruab nrab. Xws li volcanos muaj siab Kev phom sij tawg vim cov pa roj hauv lawv tsis tuaj yeem khiav ntawm cov nplaum magma yooj yim.
Tsis tas li ntawd, qhov viscosity ntawm lub roob hluav taws sib xyaw yog dab tsi? Lub lava ntws los ntawm stratovolcanoes feem ntau txias thiab hardens ua ntej kis mus deb, vim yog siab. viscosity . Lub magma tsim cov lava no feem ntau yog felsic, muaj cov qib siab-rau-nruab nrab ntawm silica (xws li hauv rhyolite, dacite, lossis andesite), nrog cov nqi tsawg dua- khov mav mag.
Tsis tas li ntawd, dab tsi yog hom eruption ntawm cinder cone volcano?
Cinder cones yog qhov yooj yim tshaj plaws hom ntawm roob hluav taws . tawg tawg tshwm sim los ntawm cov pa sai nthuav thiab khiav tawm ntawm molten lava tsim cinders uas poob rov qab nyob ib ncig ntawm lub qhov cua, tsim lub khob khob mus rau qhov siab ntawm 1,200 feet. Qhov kawg tawg tawg sab laug ib tug funnel-shaped crater nyob rau sab saum toj ntawm lub khob khob.
Puas yog cinder cone volcanoes tawg?
Composite cone volcanoes tuaj yeem loj hlob mus rau qhov siab ntawm 8,000 ko taw lossis ntau dua thiab muaj tawg tawg. Shield volcano eruptions tsawg dua tawg tshaj kev sib xyaw roob hluav taws . Cinder cone volcanoes yog ntxhab, khob khob -zoo li roob hluav taws ua los ntawm lava fragments hu ua ' cinders.

Cov ntaub ntawv dab tsi ua rau lub cinder cone volcano?
Tshuaj muaj pes tsawg leeg. Feem ntau cov cinder cones tsim los ntawm kev tawg ntawm lava ntawm basaltic muaj pes tsawg leeg, txawm tias qee daim ntawv los ntawm lava. Basaltic magmas crystallize los tsim cov pob zeb tsaus nti uas muaj cov zaub mov uas muaj hlau, magnesium thiab calcuim tab sis tsawg hauv potassium thiab sodium
Dab tsi yog cinder cone volcanoes magma chemistry?
Chemical Composition Feem ntau cov cinder cones tsim los ntawm kev tawg ntawm lava ntawm basaltic muaj pes tsawg leeg, txawm tias qee daim ntawv los ntawm lava. Basaltic magmas crystallize los tsim cov pob zeb tsaus nti uas muaj cov zaub mov uas muaj hlau, magnesium thiab calcuim tab sis tsawg hauv potassium thiab sodium
Lub cinder cone volcano tsim li cas?
Cinder cones yog hom kab hluav taws xob yooj yim tshaj plaws. Lawv yog tsim los ntawm hais thiab blobs ntawm congealed lava ejected los ntawm ib tug vent. Raws li cov roj-them lava tau tshuab ua rau huab cua hnyav, nws tawg mus rau hauv cov khoom me me uas ua kom khov thiab poob zoo li cinders nyob ib ncig ntawm lub qhov cua los ua ib lub voj voog lossis oval cone
Qhov loj ntawm lub cinder cone volcano yog dab tsi?
Cinder cone volcanoes yog me me, feem ntau tsuas yog hais txog 300 feet (91 meters) siab thiab tsis nce siab tshaj 1,200 feet (366 meters). Lawv tuaj yeem tsim nyob rau lub sijhawm luv luv ntawm ob peb lub hlis lossis xyoo
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
