Lava yog molten pob zeb generated los ntawm geothermal zog thiab raug tshem tawm los ntawm tawg nyob rau hauv planetary crust los yog nyob rau hauv ib tug eruption, feem ntau ntawm kub ntawm 700 mus rau 1, 200 ° C (1, 292 mus rau 2, 192 ° F). Cov qauv tsim los ntawm kev ua kom khov thiab txias tom qab yog kuj qee zaum piav raws li lava.
Raws li, lava science txhais li cas?
Lava yog lub pob zeb ua kua kub uas ntws los ntawm lub roob hluav taws tawg. Nyob rau hauv lub ntiaj teb lub crust yog molten pob zeb hu ua magma, nrog rau cov pa tawg. Thaum magma nce mus txog saum npoo, nws ua lava.
lava tua koj? Lava yuav tsis tua koj yog nws luv luv kov koj . Koj yuav tau txais ib tug phem hlawv, tab sis tshwj tsis yog koj poob rau hauv thiab tsis tuaj yeem tawm, koj yuav tsis tuag. Cov neeg tau tua los ntawm kev txav ceev heev lava ntws. Ib qho piv txwv tsis ntev los no yog xyoo 1977 tawg ntawm Nyiragongo.
Kuj nug, magma txhais li cas hauv kev tshawb fawb?
Magma yog molten pob zeb pom hauv qab lub ntiaj teb nto. Qhov kub ntawm lub pob zeb melts yog cuam tshuam los ntawm nws cov muaj pes tsawg leeg, siab thiab dej. Kawm li cas magma cov ntaub ntawv thiab yuav ua li cas nws yog pub volcanoes los yog txias thiab crystallizes rau hauv pob zeb igneous.
Lava yog dab tsi thiab nws tsim li cas?
Lava yog molten pob zeb. Nws yog tsim tob hauv qab lub ntiaj teb saum npoo av (feem ntau 100 mais lossis ntau dua hauv av), qhov chaw kub kub txaus kom yaj pob zeb. Cov kws tshawb fawb hu qhov no molten pob zeb magma thaum nws nyob hauv av. Thaum magma tawg mus rau lub ntiaj teb nto thiab pib ntws, cov kws tshawb fawb ces hu nws lava.

Intrusion txhais li cas hauv science?
Kev ua los yog ib qho piv txwv ntawm intruding; ib qho tsis zoo siab tuaj ntsib, cuam tshuam, thiab lwm yam: kev nkag mus rau ntawm tus kheej ntiag tug. 2. (Geological Science) a. kev txav ntawm magma los ntawm hauv lub ntiaj teb lub pob zeb mus rau hauv qhov chaw nyob rau hauv lub overlying strata los tsim igneous pob zeb
Heterozygous txhais li cas hauv science?
Hauv cov kab mob diploid, heterozygous yog hais txog ib tus neeg uas muaj ob lub alleles sib txawv rau qhov tshwj xeeb. Ib qho allele yog cov qauv ntawm cov noob caj noob ces lossis cov DNA tshwj xeeb ntawm cov chromosome. Ib tsob nroj heterozygous yuav muaj cov alleles hauv qab no rau cov noob zoo: (Rr)
Lub atomic mass txhais li cas hauv science?
Ib qho atomic mass (cim: ma) yog qhov loj ntawm ib qho atom ntawm cov tshuaj lom neeg. Nws suav nrog cov pawg ntawm 3 subatomic particles uas ua rau lub atom: protons, neutrons thiab electrons. 1 atomic mass unit txhais tau tias yog 1/12 ntawm qhov loj ntawm ib qho carbon-12 atom
Combustion txhais li cas hauv science?
Combustion los yog kub hnyiab yog ib qho kev sib txuas ntawm cov tshuaj lom neeg ntawm cov roj thiab cov oxidant nrog rau kev tsim cov cua sov los yog ob qho tib si cua sov thiab lub teeb nyob rau hauv daim ntawv ntawm aglow los yog nplaim taws. Rapid combustion yog ib daim ntawv ntawm combustion uas loj npaum li cas ntawm tshav kub thiab lub teeb zog tawm
