| x Impact crater |
|
Oberth | Pedestal crater |
In the broadest sense, the term impact crater can be applied to any depression, natural or manmade, resulting from the high velocity impact of a projectile with a larger body. In most common usage, the term is used for the approximately circular...

| x Wrinkle-ridge |
|
A wrinkle ridge is a type of feature commonly found on lunar maria. These features are low, sinuous ridges formed on the mare surface that can extend for up to several hundred kilometers. Wrinkle ridges are tectonic features created when the...

| x Lunar mare |
|
Mare Anguis |
The lunar maria (pronounced /ˈmɑrɪə/; singular: mare, two syllables /ˈmɑreɪ/) are large, dark, basaltic plains on Earth's Moon, formed by ancient volcanic eruptions. They were dubbed maria, Latin for "seas", by early astronomers who mistook them for...

| x Escarpment |
|
In geomorphology, an escarpment is a transition zone between different physiogeographic provinces that involves a sharp, steep elevation differential, characterized by a cliff or steep slope.
Usually escarpment is used interchangeably with scarp ...

| x Rille |
|
Vallis Schröteri |
Rille (German for 'groove') is typically used to describe any of the long, narrow depressions in the lunar surface that resemble channels. Typically a rille can be up to several kilometers wide and hundreds of kilometers in length. However, the term...

| x Rock |
|
Tracy's Rock |
In geology, rock is a naturally occurring solid aggregate of minerals and/or mineraloids.
The Earth's outer solid layer, the lithosphere, is made of rock. In general rocks are of three types, namely, igneous, sedimentary, and metamorphic. The...

| x Volcanic plateau |
|
Tharsis |
A volcanic plateau is a plateau produced by volcanic activity. There are two main types: lava plateaus and pyroclastic plateaus.
Lava plateaus are formed by highly fluid (runny) basaltic lava during numerous successive eruptions through numerous...

| x Cryovolcano |
|
A cryovolcano (colloquially known as an ice volcano) is, literally, an icy volcano. Cryovolcanoes form on icy moons, and possibly on other low-temperature astronomical objects (e.g., Kuiper belt objects). Rather than molten rock, these volcanoes...

| x Arachnoid |
|
In astrogeology, an arachnoid is a large structure of unknown origin, and they have been found only on the surface of the planet Venus. Arachnoids get their name from their resemblance to spider webs. They appear as concentric ovals surrounded by a...

| x Chasma |
|
Tithonium Chasma |
Chasma is a term used in astrogeology to refer to "a deep, elongated, steep-sided depression". The plural is chasmata. An example is Eos Chasma on Mars. Below are images of some of the major Chasma of Mars. The map shows their relative locations....

| x Crater chain |
|
A crater chain is a line of craters along the surface of an astronomical body. The descriptor term for crater chains is catena (plural catenae), as specified by the International Astronomical Union's rules on planetary nomenclature.
These chains are...
|
|||
| x Secondary crater |
|
Secondary craters are impact craters formed by the ejecta that was thrown out of a larger crater. They sometimes form radial crater chains.
|
|||
| x Linea |
|
Linea (pronounced /ˈlɪniːə/) is Latin for 'line'. In planetary geology it is used to refer to any long marking, dark or bright, on a planet or moon's surface. The moons Dione, Rhea, and Europa have prominent lineae.
Neero
|
|||
| x Macula |
Macula (pl. maculae) is the Latin word for 'spot'. It is used in planetary geology to refer to unusually dark areas on the surface of a planet or moon. They are seen on the icy surfaces of Jupiter's moon Europa and Neptune's moon Triton. The term...
|
||||
| x Mensa |
In planetary geology, the word mensa (pl. mensae) is used to refer to a large mesa-like area of raised land.
|
||||
| x Pedestal crater |
|
Impact crater |
In planetary geology, a pedestal crater is a crater with its ejecta sitting above the surrounding terrain and thereby forming a raised platform. They form when an impact crater ejects material which forms an erosion resistant layer, thus causing the...
|
||
| x Rupes | Discovery Rupes |
Rupes is the Latin word for 'cliff'. It is used in planetary geology to refer to escarpments on other planets, such as Mercury, and moons, such as Luna, Earth's natural satellite.
How rupes are formed is, as of 2008, a matter of speculation....

| x Scalloped margin dome |
|
A scalloped margin dome is a volcanic dome that has experienced collapse and mass wasting such as landslides on its perimeter. The margins of these domes have arcuate headscarps or 'scallops' separated by ridges that are a consequence of adjoining...

|||
| x Tholus |
In planetary geology, a tholus (pl. tholi) is the term used to describe a small domical mountain or hill. Tholus or tholi are present on the surface of Mars. They are formed from pyroclastic (volcanic) activity. The size of a tholus can be 50 to 150...

Vallis Schrödinger |
Vallis (plural valles) is the Latin word for valley. It is used in planetary geology for the naming of landform features on other planets.
Vallis (plural valles) was used for old river valleys that were discovered on Mars, when we probes were first...
