Life-stifling conditions on the surface of Venus are attributable to its thick, 97% CO2 atmosphere. The bulk composition of Earth & Venus is broadly similar, but most of Venus's CO2 content is atmosphere-resident. Heat accumulation has ensured loss of liquid water. On Earth, under subduction its volatiles CO2 and H2O are continuously recycled within the mantle, hence resident there, in sedimentary rocks, and in the world ocean, itself an important CO2 "getter". In a mobile lithosphere subduction is intrinsic. In contrast, Venus is characterized by the existence of a lithosphere static for 300 Ma. The possibility is explored that the contrast in tectonic regimes between similar planets is associated with the fundamental differences in rotation [1]. Venus rotates very slowly and is devoid of a Moon. Its minor atmospheric 'tide' rotates in direction counter to the slow solar gravity wave. Contrasting with this and with the classical tidal models of GH Darwin and AEH Love, M2 and S2 pass continuously around the Earth as 40 cm waves, in consequence of Earth's rapid rotation relative to the external gravity field. Jointly with convection, by inducing cumulative vorticity the bodily waves promote lithosphere mobility (plate tectonics), entailing subduction. -- [1] Bostrom, R.C., 1998.
