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.
