Planetotta tartiban qoqodaman akka Planet kenya kessatti, lithospheriin fesashi gara kessa argamu irra nana'a. Demma fesashi irra (convection) akkatta plastic deformationniin kan baqaa-hin-ta'in, gubba mantle fi asthenosphere irra qabatulle, lithospheriin tectonic plate demma qabanitti caccabe argama. Crustiin bishaan jalatti argamu, crustii lafa irra gargari gora. Crust bishan jalla (sima) kunin furdinana 5 hanga 10 km yoo ta'u, kan ofii kessa bayyinan qabu immo basalt dha. Crust lafa irra (sial) immo dhoqan (furdinan) 20 hanga 70 km yoo ta'u, kan ofii kessa qabus cabbi (dhaka) bayye walitti hin qabamne akka granite ofii kessa qaba. Temprecherii crust temprechera qillensa fi hanga 900 °C (gubba mantlet) jiddutti argama. Volumii planeta kenya kessa crustiin planet kenya persentii 1% qofa qabata.
