Kev daws teeb meem (Los ntawm Pab Pawg Examveda) Calderas yog qee qhov zoo nkauj tshaj plaws hauv ntiaj teb. Lawv yog cov volcanic craters loj uas tsim los ntawm ob txoj kev sib txawv: ib qho tawg volcanic eruption; los yog, tawg ntawm pob zeb saum npoo mus rau hauv qhov khoob magma chamber.
Cov khoom ntawm Volcanicity yog dab tsi?
Cov khoom tseem ceeb ntawm volcanic eruptions yuav muab faib ua ntau pawg raws li hom khoom ejected thiab nws hom kev thauj mus los ntawm lub vents mus rau nws qhov chaw ntawm deposition: ash, ntog, pyroclastics ntws., lava ntws thiab roj emission.
Calderas tuaj yeem tawg?
Nyob ntawm lawv qhov kev siv zog thiab lub sijhawm, hluav taws xob tawg tuaj yeem tsim calderas ntau li 100 mais (62 mais) dav. Ib qho caldera-ua rau tawg yog qhov kev puas tsuaj loj tshaj plaws ntawm volcanic eruption.
Puas neeg nyob hauv Calderas?
Ib lub tsev so tau teeb tsa lub khw hauv caldera thiab lwm yam kev lag luam uas tau tshoov siab rau kev ncig ua si tau tshwm sim, nees ranches thiab ntau niaj hnub ua liaj ua teb organic. Cov pej xeem puv sijhawm tau poob qis mus rau mere 15 tus neeg nyob, raws li NPR, thiab feem ntau yog cov neeg laus.
Peb hom Calderas yog dab tsi?
Variations nyob rau hauv daim ntawv thiab genesis cia calderas muab faib ua peb hom:
- Crater-Lake hom calderas cuam tshuam nrog lub cev qhuav dej ntawm stratovolcanoes.
- Bas alticcalderas txuam nrog qhov ua siab tshaj qhov tawg ntawm daim thaiv hluav taws xob.
- Resurgent calderas uas tsis muaj kev koom tes nrog ib qho chaw hauv nruab nrab.
