| These "cow pie" volcanoes are common on Venus. They are a few kilometers wide with a tiny crater in the top. Similar volcanoes occur on the deep ocean floors of Earth. Where external pressures are too great for explosive volcanism, small volcanoes seem to form domes rather than cones. |

| The "crater farm", a cluster of three young craters. The dense atmosphere of Venus has little effect on objects big enough to form craters tens of kilometers across. The ejecta forms distinct lobes, probably as a result of dense debris flows in the thick atmosphere. There are also other flows around the craters, more faintly visible. These are apparently flows of impact melt, which probably remained molten a long time due to the high temperatures on Venus. |
