Rift valleys are well known on Earth, of course. For instance, in Africa they represent the breakup of that continent into two separate plates. There also is a remarkable rift valley on the planet Venus.
Rift valley- an elongated valley formed by the depression of a block of the planet's crust between two faults or groups of faults of approximately parallel strike

The perspective in cases like this is synthesized from radar data taken from different positions in orbit.
The Great Rift Valley is a name given in the late 19th century by British explorer John Walter Gregory to the continuous geographic trough, approximately in length, ...
Eistla Regio - Rift Valley
A portion of Western Eistla Regio is displayed in this three dimensional perspective view of the surface of Venus. The viewpoint is located 725 kilometers (450 miles) southeast of Gula Mons.
Three of the four inner planets (Venus, Earth and Mars) have substantial atmospheres; all have impact craters and tectonic surface features such as rift valleys and volcanoes.
The surface of Mars shows impact craters, like the Moon, mountains, rift valleys, ridges, hills plains and extinct volcanoes. There are signs that water existed on the surface at some earlier stage of the planet.
Volcanic activity was considerably higher than today, with numerous hot spots, rift valleys, and eruption of lavas including unusual types such as komatiite.
The next summer I worked on a team project concerning Rift Valley Fever. We used RVF statistics and risk maps to produce tools that could help governments create early action plans.
It is a moon with many long rift valleys, canyons, and craters. It has a diameter of 720 miles (1158 km) and orbits Uranus at a mean distance of 120,000 miles (190,930 km). It revolves around Uranus in 50.5 Earth hours. Its mass is 1.27x1021 kg.
Whilst there is no tectonic plate motion on Mars, surface features suggest motion in the mantle. Valles Marineris, a rift valley some 4000 km long and 600 km wide, exists as well as the Tharsis rise, ...
When a few of our ancestors stared up at our lone natural satellite, they never saw the mountains which exist on the Moon, nor the huge impact craters, or long rift valleys. But they did believe they saw one kind of formation similar to the Earth.
Much of the Martian surface is very old and cratered, but there are also much younger rift valleys, ridges, hills and plains.
They are broad fractured swells with a central rift valley and usually rugged topography. They are 1-3 km in elevation, about 1500 km in width, and over 84,000 km in length.
