Crater Morphologies and Mechanics Can you answer these questions now? What are the morphologic differences between simple and complex craters? What happens during the contact, excavation, and modification stages of crater formation? How do multi-ring basins form? How do the various crater morphologies scale with crater size and with planetary gravity field? How does the transient cavity differ from the final crater? What portions of the target are ejected, melted, or otherwise modified, and how are they distributed in and around the final crater? What other kinds of modifications are seen in huge lunar craters?

and Planetary Geologic Mapping Questions for this lecture How are crater populations described? How can these populations be used to tell relative time? What is an equilibrium population, and why is its recognition important? How can crater density measurements be converted into absolute time? How are stratigraphic principles applied to planetary geologic mapping? Who first demonstrated this? How do impact craters and crater counts relate to planetary
