The Magellan mission to Venus confirmed that the surface of Venus is definitely volcanic. As shown in this picture, lava flows extend to hundreds of miles across the plains in the foreground.
The surface of Venus is an example of the fact that there are many different kinds of volcanism besides the building of volcanic cones such as those found on Earth. Among the different kinds of volcanism exhibited by Venus are:
