Venus surface is similar to Earth and Mars – few impact craters, volcanoes, and evidence of tectonics activities. But no plate tectonics. The volcanoes of Venus is most likely still active today few impact craters, sulfuric acid cloud (the volcanoes are still outgasing). However, there is no sign of erosion, no liquid water, no wind, due to its slow rotation (243 Earth days per rotation). Venus and Earth are near-twins in size, mass, composition, and conditions when they formed.
