Nyob ntawm lawv qhov kev siv thiab lub sijhawm, volcanic tawg tuaj yeem tsim calderas ntau li 100 mais (62 mais) dav. A caldera - ua rau tawg yog hom volcanic uas phem tshaj plaws tawg . Nws hloov pauv ib puag ncig ntawm thaj chaw ib puag ncig. A caldera tsis yog tib yam li qhov crater.
Raws li, calderas puas txaus ntshai?
Tab sis a caldera Lub cev qhuav dej tuaj yeem ua rau muaj kev tso pa tawm sai sai, uas tuaj yeem tawg mus rau sab nraud, raws li pom hauv kev tawg loj hauv keeb kwm kaw. Thiab qhov loj tshaj txaus ntshai tsuas yog tias lub roob poob rau ntawm nws tus kheej, uas tuaj yeem ua rau muaj av loj lossis tawg tag nrho cov cheeb tsam.
Ib yam li ntawd, qhov piv txwv ntawm lub roob hluav taws kub caldera yog dab tsi? A roob hluav taws caldera yog kev nyuaj siab nyob rau hauv av tsim los ntawm lub cev qhuav dej tom qab a roob hluav taws tawg. Qee zaum, cov caldera yog tsim maj mam, thaum av sink down tom qab ib tug magma chamber yog emptied. Lwm tus piv txwv ntawm a volcanic caldera yog Yellowstone Caldera , uas tau tawg 640,000 xyoo dhau los.
Ntawm no, yuav ua li cas calderas tsim?
A caldera yog ib lub roob hluav taws uas tsim los ntawm kev tawg ntawm lub roob hluav taws rau hauv nws tus kheej, ua rau nws loj, tshwj xeeb daim ntawv ntawm volcanic crater. A caldera Lub cev qhuav dej feem ntau tshwm sim los ntawm qhov khoob ntawm lub magma chamber hauv qab lub roob hluav taws, vim yog qhov tshwm sim ntawm lub roob hluav taws loj.
Qhov twg calderas tshwm sim?
Ib lub qhov tsua tuaj yeem tshwm sim hauv a caldera , zoo li ntawm Taal Lake hauv Philippines, tab sis tsis yog qhov thim rov qab. Calderas yog feem ntau cuam tshuam nrog kev tawg loj (cov uas tsim cov ntim ntawm 10 cubic km [2.4 cubic mais] lossis ntau dua) ntawm dacitic lossis rhyolitic magma uas tsim pyroclastic plateaus. Calderas kuj tshwm sim ntawm daim ntaub thaiv volcanoes.

Puas yog Dolomite muaj kev tawg lossis tawg?
Dolomite tsis tshua pom muaj nyob rau hauv ib puag ncig niaj hnub sedimentary, tab sis dolostones muaj ntau heev hauv cov ntaub ntawv pob zeb. Lub cev muaj zog ntawm Dolomite Chemical Classification Carbonate Diaphaneity Transparent to translucent Cleavage Perfect, rhombohedral, peb cov lus qhia Mohs Hardness 3.5 txog 4
Puas yog cinder cones tawg?
Cinder cones yog hom kab hluav taws xob yooj yim tshaj plaws. Cov tawg tawg tawg tau tshwm sim los ntawm cov roj tau nthuav dav sai thiab khiav tawm los ntawm cov lava molten tsim cinders uas poob rov qab nyob ib ncig ntawm lub qhov cua, tsim lub khob rau qhov siab ntawm 1,200 ko taw. Qhov kawg tawg tawg tau tso ib tug funnel-zoo li tus crater nyob rau sab saum toj ntawm lub khob hliav qab
Puas yog Mt Pinatubo yuav tawg dua?
20 Xyoo Tom Qab Pinatubo: Yuav Ua Li Cas Volcanoes tuaj yeem hloov pauv huab cua. Tom qab ntawd, thaum Lub Rau Hli 15, lub roob hluav taws tau tawg nws sab saum toj hauv qhov thib ob loj tshaj plaws volcanic eruption ntawm lub xyoo pua. Cov roob hluav taws no tsis yog metronomes; lawv nyiam sib txawv ntawm ib lub ntsiab lus. Txawm hais tias peb tsis cia siab tias yuav pom ib zaug ntxiv hauv peb lub neej, nws tsis yog ua tsis tau.'
Puas yog supernova tawg tawg?
Ib tug supernova (/ˌsuːp?rˈno?v?/ plural: supernovae /ˌsuːp?rˈno?viː/ los yog supernovas, cov ntawv luv: SN thiab SNe) yog qhov muaj zog thiab lub hnub qub tawg tawg. Qhov kev tshwm sim astronomical no tshwm sim thaum lub sij hawm kawg evolutionary theem ntawm lub hnub qub loj heev los yog thaum ib tug dawb dwarf tau tshwm sim rau hauv khiav tawm nuclear fusion
Dab tsi ua rau tawg tawg?
Nyob rau hauv volcanology, ib qho tawg tawg yog ib qho hluav taws kub tawg ntawm hom kev ua phem tshaj plaws. Xws li eruptions tshwm sim thaum muaj roj txaus tau yaj nyob rau hauv lub siab nyob rau hauv ib tug viscous magma xws li uas tshem tawm lava hnyav froths rau hauv volcanic tshauv thaum siab dheev txo qis ntawm lub qhov cua
