Motions of Venus' Lithosphere
A thick lithosphere would supress motions of the surface of Venus. It is not yet clear whether the lithosphere of Venus is thick or thin. The shape of the volcanoes of Venus suggests that over its history, Venus has built a thick lithosphere, like that of Mars.
On the other hand, features found on the surface, listed below, are all evidence that a planet's surface may be in motion. For Venus, these features are present but sparse, suggesting that the lithosphere does not move with the same speed, or in the same way, as that of the Earth, but is in motion nonetheless.
