Schematic cross section of a crater, with ejecta deposition at lower (left part) and higher (right part) elevations compared to flat terrain. Lower topography results in ejecta being emplaced farther from the crater, whereas higher topography intercepts the excavated ejecta closer to the crater. Note that this is a simplified representation, as ejection angles and launch positions evolve with crater formation time. Instead, ejecta are launched from progressively increasing radial distances within the transient crater during crater formation (e.g., E. M. Shoemaker 1960; D. E. Maxwell 1977; K. A. Holsapple & R. M. Schmidt 1987).
