Qhov thickening no tshwm sim los ntawm conductive txias , uas hloov kub asthenosphere mus rau lithospheric mantle thiab ua rau dej hiav txwv lithosphere oceanic lithosphere Lub Oceanic crust yog the topmost txheej ntawm lub ib feem ntawm dej hiav txwv tectonic phaj. Nws yog tsim los ntawm sab sauv dej hiav txwv crust, nrog rau hauv ncoo lavas thiab ib tug dike complex, thiab nyob rau hauv lub sab dej hiav txwv crust, muaj li ntawm troctolite, gabbro thiab ultramafic cumulates. Lub crust overlies lub solidified thiab topmost txheej ntawm lub mantle. https://en.wikipedia.org › wiki › Oceanic_crust

ua kom tuab thiab ntom nrog hnub nyoog. Qhov tseeb, dej hiav txwv lithosphere yog txheej txheej thermal ciam teb rau cov convection hauv lub mantle.
Vim li cas cov lithosphere tuab?
Dej hiav txwv lithosphere thickens raws li nws muaj hnub nyoog thiab txav deb ntawmtus ntug dej hiav txwv nruab nrab. Qhov thickening no tshwm sim los ntawm kev ua kom txias, uas hloov cov kub asthenosphere mus rau hauv lub lithospheric mantle, thiab ua rau cov dej hiav txwv lithosphere nce zuj zus nrog hnub nyoog.
Dab tsi txiav txim siab tuab ntawm lithosphere?
Cratonic continental lithosphere tuaj yeem tuab dua 200 km thiab muaj sia nyob rau ntau txhiab xyoo. Qhov no feem ntau ascribed rau ntau dua buoyancy thiab lub zog ntawm cratonic lithospheric mantlepiv rau cov hluas lithosphere. … Lwm yam tseem ceeb rau lub rheology ntawm lub mantle yog cov ntsiab lus dej.
yog dab tsilithosphere Nws tuab npaum li cas thiab nws tsim los ntawm dab tsi?
Dej hiav txwv lithosphere feem ntau yog kwv yees li 50-100 km tuab (tab sis hauv qab cov ntug dej hiav txwv nruab nrab tsis tuab dua li cov crust), thaum lub teb chaws lithosphere yog li 150 km tuab, muaj 50 km ntawm crust thiab 100km los yog ntau tshaj ntawm lub uppermost mantle.
Nyob rau hauv uas ciam teb lithosphere yog thickened?
Lub asthenosphere yog ua los ntawm cov pob zeb yaj uas ua rau nws tuab, nplaum sib xws. Lub lithosphere-asthenosphere ciam teb (LAB) yog qhov chaw uas cov lithosphere khoom hloov mus rau asthenosphere. Qhov tob ntawm LAB tsis kho, tab sis hloov pauv ntawm qhov chaw mus rau qhov chaw. … Oceanic lithosphere yog me ntsis denser.

Puas pom qhov tseem ceeb yog vim li cas lossis vim li cas ho tsis?
Kev sib txuas lus pom kev pab cov neeg tuaj saib nkag siab cov ntaub ntawv. Nws ua rau kom nkag siab txog cov ntsiab lus. Hom duab ob sab uas pab kev sib txuas lus muaj xws li kos duab, kos duab kos duab, animation, kos npe, typography, graphic designs, thiab lwm yam.
Puas yog qhov sharecropping system zoo vim li cas lossis vim li cas ho tsis?
-Sharecropping raws li keeb kwm kev coj ua nyob rau hauv American Soutic yog ntawm cov tswv yim qhev, txawm tias tsawg dua li niaj hnub ua liaj ua teb. Vim li cas thiaj tau sharecropping tsis ua haujlwm? Sharecropping khaws cia dub neeg txom nyem thiab nyob rau hauv ib txoj hauj lwm uas lawv tau zoo nkauj npaum li cas lawv tau hais los ntawm tus tswv av lawv ua haujlwm.
Puas yog lub lithosphere nyob?
Lub lithosphere yog cov khoom, sab nraud ntawm lub ntiaj teb . Nws suav nrog cov nkig sab sauv ntawm lub mantle thiab crust, lub ntiaj teb txheej txheej sab nraud. Lub lithosphere nyob rau hauv qab ntawm cov huab cua thiab saum toj no asthenosphere asthenosphere Asthenosphere.
Lithosphere tsim li cas?
Tshiab dej hiav txwv lithosphere dej hiav txwv lithosphere Lub hiav txwv dej hiav txwv yog txheej saum toj kawg nkaus ntawm cov dej hiav txwv ntawm cov phaj tectonic. Nws yog tsim los ntawm sab sauv dej hiav txwv crust, nrog rau hauv ncoo lavas thiab ib tug dike complex, thiab nyob rau hauv lub sab dej hiav txwv crust, muaj li ntawm troctolite, gabbro thiab ultramafic cumulates.
Vim li cas lithosphere tseem ceeb?
Lithosphere muab peb hav zoov, nyom nyom rau thaj av rau kev ua liaj ua teb thiab tib neeg kev nyob sib haum xeeb thiab nplua nuj ntawm cov zaub mov. Lub lithosphere muaj ntau hom pob zeb xws li igneous, sedimentary thiab metamorphic pob zeb, nws pab muab cov as-ham tsim nyog rau cov nroj tsuag.
