Ib yam li ntawd, hom volcanic eruption piav qhia txog dab tsi?
Muaj ob hom ntawm tawg nyob rau hauv cov nqe lus ntawm kev ua si, tawg tawg thiab effusive tawg . tawg tawg yog tus yam ntxwv los ntawm cov pa hluav taws xob tawg uas propels magma thiab tephra. Effusive tawg , meanwhile, yog characterized los ntawm outpouring ntawm lava tsis muaj qhov tseem ceeb tawg tawg.
Ib yam li ntawd, hom volcanic eruption feem ntau yog dab tsi? Cov feem ntau hom volcanic eruption tshwm sim thaum magma (lub sij hawm rau lava thaum nws nyob hauv qab lub ntiaj teb nto) raug tso tawm los ntawm a roob hluav taws qhov cua. Kev tawg tuaj yeem ua tau effusive, qhov twg lava ntws zoo li cov kua tuab, nplaum, lossis tawg, qhov chaw tawg ntawm lava tawg tawm ntawm lub qhov cua.
Ib yam li ntawd, plaub yam loj ntawm volcanic eruptions yog dab tsi?
Lub npe plaub hom loj ntawm volcanic eruption

Dab tsi yog hom kev phom sij tshaj plaws ntawm volcanic eruption?
Tsis xav tsis thoob, supervolcanoes yog cov yam txaus ntshai tshaj plaws ntawm lub roob hluav taws . Supervolcanoes yog ib lub tswv yim tshiab hauv volcanology. Qhov tseeb ua rau supervolcano tawg tseem tab tom sib cav, txawm li cas los xij, cov kws tshawb fawb xav tias lub magma chamber loj heev tawg tag nrho hauv ib qho kev puas tsuaj loj heev.

Dab tsi ua rau qee qhov volcanic eruptions ua rau tawg?
Kev tawg tawg tshwm sim qhov chaw txias dua, magmas ntau dua (xws li andesite) ncav cuag qhov chaw. Cov pa hluav taws xob tawg tsis tuaj yeem khiav tawm tau yooj yim, yog li lub siab tuaj yeem tsim kom txog thaum cov pa tawg tawg tawg pob zeb thiab lava tawg rau saum huab cua! Lava ntws yog ntau tuab thiab nplaum, yog li tsis txhob ntws downhill li yooj yim
Dab tsi ntxiv roj yog Lake Kivu ua rau Limnic eruptions muaj kev phom sij tshwj xeeb?
Lake Kivu txawv ntawm lwm lub pas dej tawg thiab muaj ntau cov methane hauv nws cov dej kem - 55 billion m3 thiab tseem nce ntxiv. Methane yog qhov tawg heev thiab tuaj yeem ua rau muaj kev tso tawm carbon dioxide ntxiv ib zaug
Dab tsi yog junk DNA thiab nws lub hom phiaj yog dab tsi?
Hauv cov noob caj noob ces, lo lus khib nyiab DNA hais txog thaj tsam ntawm DNA uas tsis yog coding. Qee qhov DNA noncoding no yog siv los tsim cov khoom tsis yog RNA xws li hloov RNA, tswj RNA thiab ribosomal RNA
Yuav ua li cas volcanic eruptions cuam tshuam rau tib neeg?
Cov lava nrawm nrawm tuaj yeem tua tib neeg thiab cov tshauv poob tuaj yeem ua rau lawv ua tsis taus pa. Lawv kuj tuaj yeem tuag los ntawm kev tshaib kev nqhis, hluav taws kub thiab av qeeg uas tuaj yeem cuam tshuam nrog cov roob hluav taws. Tib neeg tuaj yeem plam lawv cov khoom raws li lub roob hluav taws tuaj yeem rhuav tshem tsev, txoj kev thiab teb. Lava tuaj yeem tua cov nroj tsuag thiab tsiaj txhu
Dab tsi txaus ntshai cuam tshuam nrog volcanic eruptions?
