Shield volcanoes yog tsim los ntawm lava ntws tsawg viscosity - lava uas ntws yooj yim. Yog li ntawd, a roob hluav taws roob uas muaj qhov dav dav yog tsim los ntawm lub sijhawm ntws tom qab ntws ntawm cov kua dej basaltic lava tawm los ntawm vents los yog fissures ntawm qhov chaw ntawm lub roob hluav taws.
Kuj paub, hom lava erupts los ntawm cov ntaub thaiv npog volcanoes?
basalt
Tsis tas li ntawd, cov volcanoes puas muaj pyroclastic ntws? Shield volcanoes muaj me me ntawm pyroclastic cov ntaub ntawv, feem ntau ntawm cov uas accumulates nyob ze lub eruptive vents, tshwm sim los ntawm hluav taws kub fuming xwm txheej. Yog li, tiv thaiv volcanoes Feem ntau yog tsim los ntawm kev tawg tsis tawg ntawm cov viscosity basaltic magma tsawg.
Tsis tas li lo lus nug yog, yog vim li cas lub roob hluav taws kub hnyiab hu ua shield volcano?
A tiv thaiv volcano yog hom roob hluav taws feem ntau yuav luag tag nrho cov kua lava ntws. Nws yog npe rau nws qhov profile qis, zoo li tus tub rog daim ntaub thaiv pw hauv av.
Puas yog cov lava uas tsim cov volcanoes tiv thaiv tej zaum muaj ntau cov silica lossis dej hauv nws?
Piav koj cov lus teb. Silica vim cov lava yog heev khiav, thiab silica ua cov lava dej ntws.

Lub ntsiab txhais ntawm lo lus hluav taws xob hluav taws xob yog dab tsi?
Npe. Cov hluav taws xob hluav taws xob txhais tau tias yog hluav taws xob hluav taws xob uas tso cai rau kev ua haujlwm kom tiav. Ib qho piv txwv ntawm lub zog hluav taws xob yog lub zog los ntawm lub qhov hluav taws xob ntsaws. YourDictionary txhais thiab siv piv txwv
Lub teeb ntsuas hluav taws xob siv los kuaj xyuas hluav taws xob li cas?
Lub teeb ntsuas hluav taws xob siv lub teeb tuav hauv ib qho kev sojntsuam txuas nrog tus pas nrig taw tes nrog cov hlau txuas txuas. Qhov kev tsim no yog qhov zoo tshaj plaws rau kev tho cov hlau, kuaj lub fuse lossis kuaj xyuas qhov nqi ntawm lub roj teeb. Yog tias muaj hluav taws xob tam sim no, lub teeb yuav teeb pom tseeb tias lub voj voog muaj zog thiab ua haujlwm zoo
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
