Nyob qhov twg thiab yuav ua li cas lub roob hluav taws tsim? Raws li nws yog tsim volcanic uas?

Ib qho ntawm feem amazing thiab mysterious geological formations rau lub ntiaj teb yog volcanoes. Txawm li cas los, muaj ntau yam ntawm peb muaj rau lawv xwb ib tug ces dag to taub. Yuav ua li cas yog qhov ntawm volcanism? Nyob qhov twg thiab yuav ua li cas lub roob hluav taws tsim?

Yuav ua li cas yog lub roob hluav taws?

Ua ntej xav tias cov nqe lus nug ntawm yuav ua li cas lub roob hluav taws yog tsim, nws yog tsim nyog los delve rau hauv lub etymology thiab lub ntsiab lus ntawm lub sij hawm. Nyob rau hauv Roman mythology tus vaj tswv hais kws ntaus hlau npe hu Vulcan, uas nws lub tsev yog underground. Yog hais tias nws yog npau taws, lub ntiaj teb tau pib tshee, thiab thiaj tawg los ntawm lub depths ntawm cov pa luam yeeb thiab nplaim taws. Nws yog li no lub npe ntawm lub roob.

Lo lus "lub roob hluav taws" los ntawm lub Latin "vulcanus", uas lus txhais tau tias hluav taws kub. Volcanoes - geological formations, uas yuav tshwm sim ncaj qha saum toj no lub suab luag ua kiav txhab. Nws yog rau cov kab nrib pleb rau ntawm qhov chaw Dentistry lava tshauv, ib tug roj sib tov nrog chav thiab pob zeb. Txoj kev tshawb no ntawm no mysterious phenomenon koom nyob rau hauv science geomorphology thiab volcanology.

Classification thiab qauv

Tag nrho cov volcanoes nyob rau hauv cov xwm kev ua ub no yog muaj feem xyuam, dormant thiab tu noob. Thiab nyob rau qhov chaw - av, underwater thiab subglacial.

Yuav kom to taub li cas lub roob hluav taws yog tsim, nws yog tsim nyog ua ntej mus xav txog nyob rau hauv kom meej nws cov qauv. Txhua lub roob hluav taws yog muaj li ntawm cov nram qab no hais:

1. Muzzle (lub ntsiab channel nyob rau hauv nruab nrab ntawm lub geological tsim).
2. Dyke (s izvergsheysya lava channel).
3. Kev ua qab yias (qhov loj nyob rau saum toj ntawm lub tais).
4. Volcanic bombs (daim tawv magma izvergsheysya).
5. Volcanic chamber (feem hauv qab no tus nto qhov twg lub magma yog feeb meej).
6. Lub khob hliav qab (thiaj li hu ua "roob", tsim ntawm cov nuj nqis izvergshihsya lava tshauv).

Txawm tias muaj tseeb hais tias cov roob hluav taws zoo li ib tug lossis loj roob, nws underground ib feem ntawm ib tug loj npaum li cas ib tug uas yog nyob rau ntawm qhov chaw. Craters yog feem ntau lawm ua tus sau nrog dej.

Yog vim li cas volcanoes tsim?

Cov txheej txheem yuav pib nrog lub tsim ntawm volcanic magma chamber tsim underground. Maj mam, nws glows liab-kub kua magma, uas niamntiav siab rau lub kiav txhab ntawm hauv qab no. Nws yog vim li no, cov av pib keej. Los ntawm tej kab nrib pleb thiab pob txha lov cov magma Dentistry upward, thiab nyob rau hauv lub chav kawm ntawm nws txav nws yog yaj pob zeb thiab zoo heev nthuav lub keej. Yog li tsim volcanic kev ua qab yias. Raws li cov roob hluav taws tsim? Thaum lub sij hawm uas nyob rau hauv tus nto muaj ntau yam ntawm pob zeb, uas yog tom qab tso rau tus nqes hav, uas ib tug lub khob hliav qab yog tsim.

Qhov twg yog qhov Volcanoes?

Qhov twg volcanoes raug tsim? Cov geological formations yog faib heev unevenly nyob rau hauv lub ntiaj teb no. Yog hais tias peb tham txog cov qauv ntawm lawv tis, lub loj tus naj npawb ntawm lawv yog nyob ze ntawm lub ncaj. Nyob rau hauv lub yav qab teb Hemisphere, lawv muaj ntau tshaj nyob rau hauv sab qaum teb. Nyob rau hauv lub European ib feem ntawm Russia, Scandinavia, Australia thiab Brazil yog non-existent.

Tab sis yog hais tias peb tham txog Kamchatka, Iceland, lub Mediterranean, sab hnub poob ntug dej hiav txwv ntawm North thiab South America, lub Indian thiab cov Pacific, Central Asia thiab Central Africa, muaj ntau yam ntawm lawv. Lawv feem ntau nyob ze ntawm lub islands, archipelagos, nqaum aav ntawm continents. Feem ntau pom tau hais tias kev sib raug zoo ntawm cov kev ua ub thiab cov txheej txheem uas txuam nrog crustal taw.

Raws li nws yog tsim volcanic uas?

Nyob rau hauv dab tsi txoj kev thiab yog vim li cas volcanoes tuaj? Cov ua rau tus txheej txheem pw nyob rau hauv lub bowels ntawm lub ntiaj teb. Nyob rau hauv tus txheej txheem ntawm khaws cia ib tug loj npaum li cas ntawm magma thermal zog. Qhov kub ntawm magma yog siab txaus, tab sis nws yuav tsis yaj lub cov tub ntxhais ntawm lub ntiaj teb, vim hais tias nws pushes rau sab saum toj ua kiav txhab. Yog hais tias lub kiav txhab khaubncaws sab nraud povtseg yog pressed rau magma weaker incandescent magma yuav kua. Nws maj mam yuav noo nrog lub gases, nws melts nyob rau hauv nws txoj kev pob zeb thiab yog li prostilaet nws txoj kev mus rau qhov chaw.

Yog hais tias koj tau muaj volcanic cua khov thiab solidified lava, qhov uas yuav tsis tshwm sim raws li ntev raws li lub magma siab yog tsis txaus rau ntiab tawm no cork. Uas yog ib txwm nrog los ntawm ib tug av qeeg. Tshauv yuav ntiab tawm mus rau ib tug qhov siab ntawm ob peb kaum tawm kis lus mev.

Volcanoes sawv cev tsim, reminiscent ntawm ib lub roob, uas Dentistry los ntawm lub incandescent magma. Raws li cov roob hluav taws tsim? Nyob rau hauv lub xub ntiag ntawm cov pob txha lov nyob rau hauv lub ntiaj teb ua kiav txhab incandescent magma yog nrum rau ntawm qhov chaw nyob rau hauv siab. Slopes roob hluav taws tsim raws li ib tug tshwm sim ntawm subsidence ntawm cov pob zeb, lava, tshauv nyob ze ntawm lub cua.
