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").

Laputa Regio | Phobos | Regio | 0.00 | 265.00 | 14.00 | Fictional flying island in Jonathan Swift's Gulliver's Travels. |
There is only one regio (plural plural regiones) on Phobos as described in the nomenclature but there are still eight areas named "regio" on Mars. They are all albedo features.

Rupes (plural rupēs) is a word of Latin origin for a rock or cliff. It is used to describe a linear escarpment or the face of a relatively straight cliff, as opposed to scopulus.

Scopulus (plural scopuli) is a word of Latin origin that refers to a rock or cliff. This term is used in exogeology to describe a lobed or irregular cliff or escarpment as opposed to the relatively straight cliffs of rupes type.

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.

Strictly speaking, there are no sinūs (small plains) on Mars as described in the nomenclature, but there are seven areas named "sinus". They are all albedo features.

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.
Latitudes and longitudes in white are planetocentric. Those in orange use the older planetographic system.
