This process happens on all the terrestrial planets, though less frequently today than in the distant past. The surfaces of the moon and Mercury show the most craters today, because there has been little other geological activity there to erase the craters, even over billions of years. Thus, mountains wear down and valleys get filled in. These processes obviously require an atmosphere, so they do not occur on the moon or Mercury. There is wind erosion on Venus and Mars, though less than on earth because Venus is less windy and Mars has such a thin atmosphere.
Erosion is most important on earth, because earth also has liquid water which causes much erosion.
The atmosphere of Venus, which is very dense and composed mostly of carbon dioxide, is highly opaque to infrared light. Sunlight penetrates relatively far down into the atmophere, heating the lower layers. These layers then give off infrared light which is trapped by the upper layers. Because it is so hard for heat to escape from the lower atmosphere, it becomes very hot, heating the surface as well. Volcanic activity is caused by heat, below the surface, trying to escape.
