Volcanoes and lava flows
Earth's surface has been renewed over the eons by plate tectonics, volcanism and other processes. But Venus does not appear to have tectonic plate activity. What is certain is that the surface of Venus has been shaped by deformation of the crust and volcanic activity. Venus volcanism indicates that, at least in the past, the crust was laying on a liquid mantle, as on Earth. The key question is, are volcanoes still active on Venus today?ESApod audio programme
