Magma thiab lwm yam roob hluav taws cov ntaub ntawv raug xa mus rau qhov chaw uas lawv raug tshem tawm los ntawm kev tawg lossis qhov. Lub ntsiab qhov chaw ntawm lub roob hluav taws suav nrog magma chamber, conduits, vents, craters thiab slopes. Muaj peb hom roob hluav taws : cinder cones, stratovolcanoes thiab ntaub thaiv npog roob hluav taws.
Ua li no, lub hauv qab ntawm lub roob hluav taws hu ua dab tsi?
Ib txhia roob hluav taws muaj ib yam dab tsi hu ua ib caldera. Lub caldera tsim thaum a roob hluav taws tau txais hollow thiab ces collapses rau nws tus kheej. Ib tug caldera yuav zoo li ib tug loj indentation nyob rau sab ntawm lub roob hluav taws los yog nws tuaj yeem tshwm sim ntawm qhov kawg.
Tsis tas li ntawd, koj yuav sau lub roob hluav taws li cas? Sau lub Volcano
- Tshauv, Chav, thiab Gas - huab uas raug thawb tawm ntawm lub roob hluav taws.
- Secondary Cone - lub khob hliav qab uas tsim nyob ib ncig ntawm cov vents.
- Secondary Vent - qhov chaw uas magma nce mus txog saum npoo yam tsis tau hla lub qhov cua loj.
- Crater? - ncig kev nyuaj siab nyob rau sab saum toj ntawm lub roob hluav taws.
Tsuas yog li ntawd, dab tsi yog qhov tseem ceeb ntawm lub roob hluav taws?
Daim duab hauv qab no qhia txog qhov cov yam ntxwv tseem ceeb ntawm lub roob hluav taws . Lub magma chamber yog lub pas dej loj hauv av ntawm magma. Nyob rau hauv lub siab lub magma nyob rau hauv lub chamber yuav sawv li lub ntsiab vent uas yog lub hauv paus raj ntawm lub roob hluav taws . Volcanoes feem ntau muaj ib lub tais zoo li lub tais rau saum lub roob hluav taws , hu ua crater.
Lub roob hluav taws tsim li cas?
Volcanoes yog tsim Thaum magma los ntawm hauv lub ntiaj teb sab sauv mantle ua haujlwm rau saum npoo. Nyob rau saum npoo, nws erupts tsim lava ntws thiab tshauv deposits. Sijhawm dhau los ua tus roob hluav taws txuas ntxiv mus, nws yuav loj dua thiab loj dua.
