Caldera tawg tshwm sim Thaum lub magma chamber sib sib zog nqus hauv qab lub roob hluav taws ntws tawm sai sai. Lub bedrock saum toj no pancakes cia rau hauv lub resulting void, tsim los yog sib sib zog nqus kev nyuaj siab nyob rau hauv lub roob hluav taws. Qhov tseeb series ntawm cov xwm txheej ntawm a vaum thiab ib qho kev tawg yog tseem raug txheeb tawm.
Ua raws li qhov no, yuav ua li cas thaum lub roob hluav taws tawg?
Ib tug caldera yog ib roob hluav taws feature tsim los ntawm cov vaum ntawm a roob hluav taws rau hauv nws tus kheej, ua rau nws loj, tshwj xeeb daim ntawv ntawm roob hluav taws qhov hluav taws kub. Ib caldera vaum feem ntau tshwm sim los ntawm qhov khoob ntawm magma chamber hauv qab roob hluav taws , raws li qhov tshwm sim ntawm ib tug loj roob hluav taws tawg.
Yuav ua li cas los tsim caldera? lub magma chamber empties, lub roob hluav taws tawg, a caldera daim ntawv. cov ntaub ntawv thaum magma pushes tab sis tau nkhaus thiab hardens, tsim roob. caldera . Ib lub qhov loj loj uas tshuav los ntawm qhov tawg ntawm lub roob hluav taws.
Ua li no, calderas tseem tuaj yeem tawg?
Crater-lake calderas tshwm sim los ntawm lub cev qhuav dej ntawm lub stratovolcano tom qab ib tug Plinian tawg , feem ntau tawg hom volcanic tawg . Plinian tawg tso tawm ntau cov lava, volcanic tshauv, thiab pob zeb. Tsis zoo li Mount Mazama, Deception volcano yog tseem nquag.
Muaj pes tsawg lub roob hluav taws Caldera?
Peb caldera -kev ua eruptions, feem, yog hais txog 2, 500, 280, thiab 1,000 lub sij hawm loj tshaj lub Tsib Hlis 18, 1980 eruption ntawm Mt.

Yuav ua li cas tshwm sim thaum magma txias thaum lub sij hawm lub pob zeb quizlet?
Raws li cov magma cools, loj thiab loj muaju tsim raws li lub pob zeb hardens. Yog tias magma tawm hauv lub ntiaj teb, lub pob zeb molten tam sim no hu ua lava. Thaum cov lava no txias rau ntawm lub ntiaj teb saum npoo, nws tsim cov pob zeb extrusive igneous. Lava txias sai heev, yog li cov pob zeb extrusive igneous tsis muaj crystals zoo
Yuav ua li cas cov thawj windings txuas thaum lub transformer yuav tsum tau ua nyob rau hauv ib tug 480 volt system?
Lub transformer muaj qhov polarity rho tawm thaum lub davhlau ya nyob twg H1 nyob ib sab ntawm lub davhlau ya nyob twg X1. Thaum lub 240/480 volt dual thawj tswj transformer yuav tsum tau ua los ntawm ib tug 240 volt system thawj winding yog kev cob cog rua nyob rau hauv parallel. Hauv Delta-connected transformer, theem thiab kab voltages sib npaug
Yuav ua li cas tshwm sim rau lub parallel phaj capacitor thaum lub dielectric muab tso rau ntawm daim hlau?
Thaum cov khoom siv dielectric tau qhia nruab nrab ntawm daim hlau Thiab thaum cov khoom siv dielectric muab tso rau nruab nrab ntawm daim hlau ntawm cov paib sib npaug ntawm cov phaj capacitor ces vim polarization ntawm cov nqi ntawm ob sab ntawm dielectric, nws tsim hluav taws xob teb ntawm nws tus kheej uas ua nyob rau hauv ib qho kev taw qhia opposite. rau lub teb vim
Yuav ua li cas tshwm sim rau lub zog binding thaum lub loj tus naj npawb nce?
Daim duab saum toj no qhia tau hais tias raws li cov atomic huab hwm coj nce, lub zog khi ntawm ib lub nucleon txo qis rau A> 60. Hauv lwm lo lus, BE / A tau txo qis. BE/A ntawm lub nucleus yog qhov qhia txog nws qhov kev ruaj ntseg. Feem ntau, cov nuclides ruaj khov muaj ntau dua BE / A dua li cov tsis ruaj khov
Thaum twg koj yuav tsum siv correlation thiab thaum twg koj yuav tsum siv yooj yim linear regression?
Regression feem ntau yog siv los tsim cov qauv / qhov sib npaug los kwv yees cov lus teb tseem ceeb, Y, los ntawm cov txheej txheem kwv yees (X) sib txawv. Kev sib raug zoo feem ntau yog siv los ua kom sai thiab ua kom luv luv cov kev taw qhia thiab lub zog ntawm kev sib raug zoo ntawm ib pawg ntawm 2 lossis ntau tus lej sib txawv
