Lithosphere yog tsim los ntawm lub ntiaj teb txheej txheej sab nraud, lub crust, thiab qhov saum toj kawg nkaus ntawm lub mantle. Hauv kev sib piv, lub asthenosphere yog lub sab sauv ntawm lub ntiaj teb lub mantle (uas kuj yog nruab nrab txheej ntawm lub ntiaj teb). Cov asthenosphere yog ntau ntom thiab viscous piv rau cov lithosphere.
Ua raws li qhov no hauv kev xav, dab tsi yog qhov txawv ntawm lithosphere thiab asthenosphere?
Hauv cov ntsiab lus ntawm tshuaj muaj pes tsawg leeg, tsis muaj qhov sib txawv ntawm sab sauv ntawm tus asthenosphere thiab qhov qis ntawm lithosphere . Cov lithosphere yog ua los ntawm crust ntxiv rau lub sab sauv heev ntawm lub mantle, whereas lub asthenosphere tsuas yog cov khoom siv sab saud xwb.
Tsis tas li ntawd, qhov ceev ntawm asthenosphere yog dab tsi? - Asthenosphere - txhais tau tias ceev txog 3.3 g / cc.
Ib yam li ntawd, nws yog nug, dab tsi yog qhov ceev ntawm lithosphere thiab asthenosphere?
Teb thiab piav qhia: Muaj ob hom lithosphere : dej hiav txwv thiab continental. Oceanin lithosphere yog hais txog 2.9g / cm3 c m 3 nyob rau hauv ceev thiab continental lithosphere yog hais txog 2.7g / cm3 c m 3 in ceev . Cov asthenosphere yog ntom, kwv yees li ntawm 3.3g / cm3 c m 3.
Dab tsi yog qhov txawv ntawm lithosphere thiab asthenosphere quizlet?
Cov lithosphere yog lub phaj tectonic thiab muaj crust (continental thiab dej hiav txwv), Moho kab, Upper Mantle Rigid. Cov asthenosphere yog qhov chaw convection tam sim no tsav cov phaj sib nrug thiab muaj cov Upper Mantle ntws. Oceanic crust yog tuab thiab nyias. Continental crust yog tuab tab sis tsawg ntom.

Dab tsi yog cov yam ntxwv ntawm asthenosphere?
Lub asthenosphere (los ntawm Greek? Σ θ ε ν ή ς asthen? S 'tsis muaj zog' + 'kheej') yog mas khov, mechanically tsis muaj zog thiab ductilelydeforming cheeb tsam ntawm lub sab sauv mantle ntawm lub ntiaj teb. Nws nyob hauv qab lithosphere, ntawm qhov tob ntawm kwv yees li 80 thiab 200 km (50 thiab 120 mais) hauv qab ntawm qhov chaw
Dab tsi yog asthenosphere luv?
Lub asthenosphere yog qhov khov heev, mechanically tsis muaj zog thiab ductile cheeb tsam ntawm lub sab sauv mantle ntawm lub ntiaj teb. Nws nyob hauv qab lithosphere, ntawm qhov tob ntawm kwv yees li 80 thiab 200 km (50 thiab 120 mais) hauv qab ntawm qhov chaw
Ib qho piv txwv ntawm asthenosphere yog dab tsi?
Asthenosphere. Txhais: Cov txheej mos ntawm lub mantle hauv qab lithosphere. Piv txwv li: Lower Mantle
Dab tsi yog qhov txawv ntawm mantle thiab asthenosphere?
Lub lithosphere muaj mantle uas yog khoom, zoo li lub crust, whereas asthenosphere tsuas yog mantle uas kub txaus,> 1280C, tso cai rau convection tam sim no tshwm sim. Lub mantle yog tag nrho cov txheej ntawm pob zeb ntawm lub crust thiab core, whereas lub asthenosphere yog ib tug tsis muaj zog txheej ntawm lub Upper mantle uas muaj peev xwm mus convect
Nws txhais li cas rau ib yam dab tsi kom denser?
Npe. Lub ntsiab txhais ntawm denser yog ib yam dab tsi uas tau ntim ntau nruj los yog muaj neeg coob coob. Ib qho piv txwv ntawm denser yog ib lub tsheb subway uas twb tau ntim lawm tom qab lwm tsib tus neeg tau mus. YourDictionary txhais thiab siv piv txwv
