Solution

Ejecta

The ejecta of a smaller crater often consists of fragmented material that has been expelled during the impact event. This material can range from fine ash to larger boulders. The texture of the ejecta is typically rough and granular, showing signs of abrasion from the high-velocity impact. It may also display variations in size and composition, with different layers reflecting the dynamics of the explosion.

Rim

The rim of a smaller crater is characterized by its raised, often steep edges. The texture is generally rugged and can show signs of mass wasting, with loose particles and debris accumulating at the base. This region may have a rough, jagged appearance due to the uplift of underlying material and the fracturing caused by the impact.

Floor

The floor of the smaller crater typically features a smoother texture compared to the rim. It may be covered with fine dust or sediments that settled post-impact. This area can also exhibit layered deposits or impact-melt materials, with various textures ranging from smooth, glassy surfaces to more irregular, rocky patches.

Central Peak

In smaller craters, a pronounced central peak is less common than in larger craters, but if present, it may display a more intricate texture. The central peak often features a rugged surface with exposed rock formations, which can be characterized by fractures and folds as a result of the structural rebound following the impact. The texture may vary from coarse to fine, depending on the composition of the underlying geology.

Overall, each feature in a smaller crater exhibits a distinct textural profile influenced by the impact dynamics and subsequent geological processes.
