Quizplus · Accepted Answer

The surface of Venus appears to have undergone a significant repaving event in the past billion years or so, erasing nearly all of the surface features that existed earlier. This is supported by the lack of large impact craters and the uniformity of the surface features observed by spacecraft. While the other events listed (eruption of a giant volcano, impact of a large asteroid, onset of mantle convection) may have had an impact on the planet, the repaving event appears to be the most significant based on the available evidence.
