Crater morphology is the study of the physical characteristics and features of impact craters, which are circular depressions on the surface of a planet or moon that are formed by the impact of a meteoroid, asteroid, or comet. Researchers in this area study the size, shape, depth, and distribution of craters, as well as the processes that govern their formation and evolution. By analyzing the morphology of impact craters, scientists can learn about the history of a planetary surface, the frequency and intensity of impacts, and the geological processes at work on different celestial bodies. Crater morphology research can also provide valuable insights into the age and composition of planetary surfaces, as well as the potential for past or present habitability.
