Kaw calderas daim ntawv thaum a loj magmachamber yog emptied los ntawm a roob hluav taws eruption los yog subsurfacemagma txav. Lub pob zeb unsupported ntawd daim ntawv lub ru tsev ntawm lub magma chamber ces collapses mus daim ntawv ib tus dej loj.

Tsis tas li ntawd, cov ntaub ntawv twg nyob rau hauv lub crater ntawm lub roob hluav taws loj apex?

Ib tug caldera yog ib roob hluav taws feature tsim los ntawm lub cev qhuav dej ntawm a roob hluav taws nyob rau hauv nws tus kheej, ua nws ib loj , tshwj xeeb daim ntawv ntawm volcanic crater . Acaldera vau feem ntau yog tshwm sim los ntawm qhov khoob ntawm lub magmachamber hauv qab roob hluav taws , raws li qhov tshwm sim ntawm a loj volcanic eruption.

Ib yam li ntawd, cov craters tsim los ntawm volcanoes li cas? Craters tuaj nyob rau hauv ob yam: cov uas tsis yog tshwm sim los ntawm asteroids los yog comets, cuam tshuam cov qhov tsua , yog tsim los ntawm lub zog roob hluav taws tawg. Xws li kev tawg tuaj yeem ua rau muaj kev kub ntxhov txaus uas thaum qhov hluav taws kub dhau lawm, qhov roob hluav taws collapses nyob rau hauv nws qhov khoob khoob magma chamber thiab tsim ib caldera, los yog volcanic crater.

Ib yam li ntawd, lub crater nyob rau sab saum toj ntawm lub roob hluav taws hu ua dab tsi?

Nyob ntawm saum ntawm roob hluav taws , ntawm nws qhov siab tshaj plaws, yog a qhov hluav taws kub . Ib txhia roob hluav taws muaj ib yam dab tsi hu ua ib caldera. Lub caldera tsim thaum a roob hluav taws getshollow thiab ces collapses rau nws tus kheej. Ib tug caldera yuav zoo li alarge indentation nyob rau sab ntawm lub roob hluav taws los yog nws yuav tshwm sim ntawm lub heev saum.

Dab tsi yog 6 qhov tseem ceeb ntawm lub roob hluav taws?

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. Cov qhov tseem ceeb 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.
