Thaum lub pob zeb molten tseem nyob sab hauv tus roob hluav taws , thiab sab hauv lub ntiaj teb crust, nws yog hu ua magma. Thaum lub magma los rau saum npoo thiab tawg los yog ntws tawm ntawm lub roob hluav taws , lub sij hawm rau nws yog lava.
Khaws qhov no rau hauv kev xav, dab tsi yog qhov txawv ntawm lub roob hluav taws?
Magma thiab lwm yam khoom siv hluav taws xob tau xa mus rau qhov chaw uas lawv raug tshem tawm los ntawm kev tawg lossis qhov. Qhov tseem ceeb ntawm lub roob hluav taws muaj xws li magma chamber, conduits, vents, craters thiab slopes. Muaj peb hom volcanoes: cinder cones, stratovolcanoes thiab shield volcanoes.
Ib yam li ntawd, volcanoes hu ua dab tsi? Volcanoes tau muab faib ua plaub hom: cinder cones, composite roob hluav taws , daim ntaub thaiv roob hluav taws thiab lava roob hluav taws . Cinder Cones. Cinder cones yog ncig los yog oval cones ua los ntawm cov tawg me me ntawm lava los ntawm ib lub qhov cua uas tau raug tshuab mus rau hauv huab cua, txias thiab poob ib ncig ntawm lub qhov cua.
Yog li ntawd, qhov nruab nrab ntawm lub roob hluav taws hu ua dab tsi?
Teb thiab piav qhia: Lub qhov chaw ntawm lub roob hluav taws yog hu ua qhov nruab nrab qhov cua. A roob hluav taws yog tsim thaum lub ntiaj teb tectonic daim hlau txav.
Lub hauv paus qauv ntawm lub roob hluav taws yog dab tsi?
Cov qauv ntawm lub Volcano . A roob hluav taws yog qhov qhib rau saum npoo ntawm lub ntiaj teb uas tso cai rau cov pob zeb kub, molten, tshauv, thiab gases kom khiav tawm hauv qab ntawm qhov chaw los ntawm cov yeeb nkab zoo li qhov hluav taws xob hu ua lub qhov cua. Cov eruptions no ua ib lub cone-shaped landform ua los ntawm cov ntaub ntawv no.

Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Lub co2 hluav taws tua hluav taws puas ua haujlwm ntawm hluav taws kub oxidizer?
Lub tshuab tua hluav taws xob carbon dioxide tsis yog qhov kev xaiv zoo rau kev tua hluav taws oxidizer vim nws ua haujlwm ntawm lub hauv paus ntsiab lus ntawm kev tsis suav nrog cov pa oxygen, thiab cov pa oxygen atmospheric tsis xav tau rau hluav taws kub oxidizer. Cov tshuaj tua hluav taws qhuav qhuav kuj tseem yuav siv tsis tau rau feem ntau
Dab tsi yog kev sib raug zoo ntawm sab nrauv thiab sab hauv lub kaum sab xis ntawm daim duab peb sab?
Cov kaum sab hauv yog hu ua Sab hauv cov ces kaum. Cov lej ntawm cov kaum sab hauv ntawm daim duab peb sab yog ib txwm 180 degrees. Lub kaum sab nrauv yog lub kaum sab xis ntawm ib sab ntawm ib qho duab, thiab ib txoj kab txuas ntxiv los ntawm sab tom ntej. Qhov sib npaug ntawm lub kaum sab nrauv thiab nws lub kaum sab hauv uas nyob ib sab kuj yog 180 degrees
