Muaj peb yooj yim khob khob cov duab thiab rau eruption hom. Cov peb cone cov duab yog cinder cones , daim ntaub thaiv cones , thiab composite cones los yog stratovolcanoes. Lub rau lub eruption hom yog nyob rau hauv kev txiav txim los ntawm tsawg kawg nkaus tawg mus rau feem ntau tawg; Icelandic, Hawaiian, Strombolian, Vulcanian, Pelean, thiab Plinian.
Tsis tas li lo lus nug yog, dab tsi yog 3 hom volcanic cones?
Muaj peb hom volcano loj - sib xyaw los yog strato, ntaub thaiv npog thiab dome. Composite volcanoes , qee zaum hu ua strato volcanoes , yog steep sided cones tsim los ntawm txheej ntawm tshauv thiab [ lava ] ntws. Cov eruptions los ntawm cov volcanoes tej zaum yuav yog ib tug pyroclastic ntws es tsis yog ib tug ntws lava.
Tsis tas li ntawd, yuav ua li cas txhua hom volcanic cones tuaj yeem tsim tau? Lawv daim ntawv thaum txawv hom ntawm eruptions tso cov khoom sib txawv nyob ib ncig ntawm ib sab ntawm ib roob hluav taws . Alternating erruptions ntawm roob hluav taws ash thiab lava ua rau cov khaubncaws sab nraud povtseg daim ntawv . Nyob rau tib lub sijhawm, cov txheej txheem no tsim. Qhov tshwm sim yog a khob khob uas muaj ib tug maj mam nqes dua ib cinder cone tab sis yog steeper dua ib daim ntaub thaiv roob hluav taws.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog lub khob hliav qab nyob rau hauv lub roob hluav taws?
A volcanic cone yog daim duab peb sab-puab toj tsim los ntawm cov khoom siv volcanic eruptions pawg nyob ib ncig ntawm roob hluav taws vent, los yog qhib nyob rau hauv lub ntiaj teb crust. Feem ntau volcanic cones muaj ib roob hluav taws crater, los yog central depression, nyob rau saum toj.
Dab tsi yog qee qhov piv txwv ntawm cinder cone volcanoes?
Daim ntawv teev cov cinder cones
- Lava Butte, lub khob hliav qab hauv Newberry National Volcanic Monument, Oregon.
- Tseax Cone lava txaj npog nrog moss thiab lichen.
- Kostal Cone.
- Sab qab teb ntawm Cocoa Crater.
- Parícutin nyob rau hauv 1994.
- Amboy Crater, raws li tau pom los ntawm sab hnub tuaj.
- Schonchin Butte los ntawm Cave Loop Road.
- Mount Fox crater.

Dab tsi yog qhov txawv ntawm pob zeb volcanic thiab plutonic?
Qhov no yog vim hais tias plutonic pob zeb yog pob zeb tsim thaum magma txias thiab solidifies hauv qab lub ntiaj teb nto, thiab volcanic pob zeb yog pob zeb tsim thaum lava txias thiab solidifies ntawm lub ntiaj teb nto
5 hom volcanic eruptions yog dab tsi?
Rau hom eruptions Icelandic. Hawaiian. Strombolian. Vulcanian. Pelan. Plinian
Dab tsi yog qhov tsis zoo ntawm volcanic eruption?
Cov plua plav zoo ua rau lub ntsws tsis zoo thiab ua tsis taus pa. Lub roob hluav taws tso tawm cov foob pob lava uas tuaj yeem xuas lub qhov hauv nkoj, dav hlau thiab cov phab ntsa. Cov tshauv kub heev thiab hmoov av tuaj yeem npog thiab rhuav tshem tsheb, tsev, txawm tias tag nrho cov zos
Puas muaj qhov sib txawv ntawm txiv neej conifer cones thiab poj niam conifer cones?
Pine cones feem ntau xav tias yog ntoo thuv cones yog qhov loj dua poj niam ntoo thuv cones; txiv neej Pine cones tsis zoo li woody thiab muaj ntau me me. Poj niam Pine cones tuav cov noob thaum txiv neej Pine cones muaj cov paj ntoos. Feem ntau cov conifers, los yog cone- bearing ntoo, muaj poj niam thiab txiv neej Pine cones rau tib tsob ntoo
Dab tsi yog spatter cones?
Spatter cones yog ib qho tseem ceeb ntawm volcanic hom landforms. Lawv yog tsim los ntawm lava uas tau tawm los ntawm lub qhov cua. Cov spatter cones yog ib qho yooj yim kom paub qhov txawv tshwj xeeb tshaj yog thaum tawg. Tsis zoo li qee lub roob hluav taws uas tsim cov lava ntws thaum lub sijhawm tawg, qhov tawg ntawm cov pob zeb tawg zoo ib yam li tawg
