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.

Cov kev cuam tshuam ntawm lub teeb-dependent siv lub teeb lub zog los ua ob lub molecules uas xav tau rau theem tom ntej ntawm photosynthesis: lub zog cia molecule ATP thiab txo cov khoom siv hluav taws xob NADPH. Nyob rau hauv cov nroj tsuag, lub teeb tshwm sim tshwm sim nyob rau hauv lub thylakoid daim nyias nyias ntawm organelles hu ua chloroplasts
Qhov txawv ntawm qhov loj ntawm ib tug proton thiab qhov loj ntawm ib tug electron yog dab tsi?
Protons thiab neutrons muaj kwv yees li qub, tab sis lawv yog ob qho tib si loj dua li cov hluav taws xob (kwv yees li 2,000 npaug loj li electron). Tus nqi zoo ntawm ib qho proton yog sib npaug hauv qhov loj rau qhov tsis zoo ntawm tus electron

Yog tias tus poj niam uas muaj lub zeem muag zoo li no (heterozygous rau qhov muag tsis pom xim) yuav ib tug txiv neej ib txwm muaj (XY), cov xeeb ceem hauv qab no tuaj yeem xav tau hauv F2 tiam: ntawm cov ntxhais, 50% yog ib txwm muaj thiab 50% yog cov neeg nqa khoom rau cov kab mob; ntawm cov tub, 50% yog xim dig muag thiab 50% yog qhov pom kev zoo
Lub ntiaj teb nyob rau hauv orbit nyob ib ncig ntawm lub hnub qub uas tsis yog peb lub hnub?
Cov Lus Teb luv luv: Cov ntiaj chaw uas nyob ib puag ncig lwm lub hnub qub hu ua exoplanets. Tag nrho cov ntiaj chaw nyob rau hauv peb lub hnub ci system orbit ncig lub hnub. Cov ntiaj chaw uas nyob ib ncig ntawm lwm lub hnub qub yog hu ua exoplanets. Exoplanets yog qhov nyuaj heev kom pom ncaj qha nrog telescopes
