What surface features are almost completely absent on the far side?

The far side of the Moon is characterized by a notable absence of large, flat maria (basaltic plains) that are prevalent on the near side. Instead, it features a more rugged terrain with a higher density of impact craters and mountainous regions. This difference is attributed to the thicker crust on the far side, which inhibited volcanic activity and the formation of maria. As a result, the far side presents a starkly different landscape compared to the near side.
