List of plana

In planetology, a planum (plural plana) is a flat, horizontal and elevated surface, in other words a high plateau or an elevated plain, most often of volcanic or cryovolcanic origin. This type of formation is therefore opposed to the low plains of the planitia type. The word is borrowed from Latin ("flat surface").

List of serpentes

Serpens (plural serpentes) is a Latin term, from the original meaning of "snake", used in the field of exogeology to indicate a superficial feature in which sinuous-trending features follow each other with positive height and negative height relative to the surrounding environment. From a geological point of view, it is thought that this type of formation was the bottom of a river or lava channel where various erosion or cementification phenomena occurred. The first structure officially classified as serpens was the Aeolis Serpens of Mars.

List of sulci

Sulcus (plural sulci is a word of Latin origin designating a furrow, a ditch, a fold or a wrinkle. It is used on Mars, on the satellite Ganymede of Jupiter, on the satellite Enceladus of Saturn, on the satellite Miranda of Uranus and on the satellite Triton of Neptune to describe more or less parallel furrows and wrinkles that appear on folded terrain.
