Rift
In geology, a rift is a linear zone where the lithosphere is being pulled apart and is an example of extensional tectonics. Typical rift features are a central linear downfaulted depression, called a graben, or more commonly a half-graben with normal faulting and rift-flank uplifts mainly on one side. Where rifts remain above sea level they form a rift valley, which may be filled by water forming a rift lake. The axis of the rift area may contain volcanic rocks, and active volcanism is a part of many, but not all, active rift systems. Major rifts occur along the central axis of most mid-ocean ridges, where new oceanic crust and lithosphere is created along a divergent boundary between two tectonic plates. ''Failed rifts'' are the result of continental rifting that failed to continue to the point of break-up. Typically the transition from rifting to spreading develops at a triple junction where three converging rifts meet over a hotspot. Two of these evolve to th ...

Colca Canyon
The Colca Canyon is a canyon of the Colca River in southern Peru, located about northwest of Arequipa. With a depth of about 1000 - 2000 m (3300 - 6600 ft) (whereas bottom is at cca 2000 m and edges are at 3000 - 4000 metres above the sea level), it is one of the deepest canyons in the world. Its length is about . The Colca Valley is a colorful Andean valley with pre-Inca rooted inhabitants, and towns founded in Spanish colonial times, still inhabited by people of the Collagua and the Cabana cultures. The local people maintain their ancestral traditions and continue to cultivate the pre-Inca stepped terraces, called andenes. It is Peru's third most-visited tourist destination with about 120,000 visitors annually. History The Quechua-speaking Cabanas, probably descended from the Wari culture, and the Aymara-speaking Colleagues, who moved to the area from the Lake Titicaca region, inhabited the valley in the pre-Inca era. The Inca probably arrived in the Colca Valley ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saturnalia Fossa
Saturnalia Fossa is the largest of the series of parallel Veneneian troughs in the northern hemisphere of the giant asteroid 4 Vesta. It is estimated to be approx. wide and is at least ; as of early 2012, one end disappeared in shadow and its total length was thus unknown. It is thought to be a shock fractures resulting from the impact that created Veneneia crater, which it is concentric with.

Rheasilvia
Rheasilvia is the most prominent surface feature on the asteroid Vesta and is thought to be an impact crater. It is in diameter, which is 90% the diameter of Vesta itself, and is 95% the mean diameter of Vesta, . However, the mean is affected by the crater itself. It is 89% the mean equatorial diameter of , making it one of the largest craters in the Solar System, and at 75°S latitude, covers most of the southern hemisphere. The peak in the center of the crater is in diameter, and rises from its base, making it one of the tallest mountains known in the Solar System. Discovery Rheasilvia was discovered in Hubble Space Telescope images in 1997, but was not named until the arrival of the ''Dawn'' spacecraft in 2011. It is named after Rhea Silvia, a mythological vestal virgin and mother of the founders of Rome, Romulus and Remus.(NASA coordinates) Characteristics The crater partially obscures an earlier crater, named Veneneia, that at is almost as large.

Divalia Fossa
Divalia Fossa is the largest of the series of parallel Rheasilvian equatorial troughs on the giant asteroid 4 Vesta. It is approximately wide (estimated at its widest point) and encircles "most" of Vesta's equator, or for at least , and is about deep. It is thought to be a compression fracture resulting from the impact that created Rheasilvia crater. It is one of the longer chasms in the Solar System, and is named after the Roman festival of Divalia. (NASA coordinates) See also *Saturnalia Fossa

4 Vesta
Vesta ( minor-planet designation: 4 Vesta) is one of the largest objects in the asteroid belt, with a mean diameter of . It was discovered by the German astronomer Heinrich Wilhelm Matthias Olbers on 29 March 1807 and is named after Vesta, the virgin goddess of home and hearth from Roman mythology. Vesta is thought to be the second-largest asteroid, both by mass and by volume, after the dwarf planet Ceres, though in volume it overlaps with the uncertainty in the measurements of 2 Pallas.Marsset, M., Brož, M., Vernazza, P. et al.

Ares Vallis
Ares Vallis is an outflow channel on Mars, named after the Greek name for Mars: Ares, the god of war; it appears to have been carved by fluids, perhaps water. The valley 'flows' northwest out of the hilly Margaritifer Terra, where the Iani Chaos depression long and wide) is connected to the beginning of Ares Vallis by a wide transition zone centered on 342.5° East (17.5 West) and 3° North. It then continues through the ancient Xanthe Terra highlands, and ends in a delta-like region of Chryse Planitia. Ares Vallis was the landing site of NASA's ''Mars Pathfinder'' spacecraft, which studied a region of the valley near the border with Chryse in 1997. Ares Vallis is in the Oxia Palus quadrangle of Mars. It has been argued that Uzboi, Ladon, Margaritifer and Ares valles, although now separated by large craters, once comprised a single outflow channel, flowing north into Chryse Planitia. The source of this outflow has been suggested as overflow from the Argyre Crater, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tiu Valles
The Tiu Valles are an outflow channel system in the Oxia Palus quadrangle of Mars, centered at 16.23° North and 34.86° West. They are long and were named after the word for "Mars" in Old English (West Germanic).

Kasei Valles
The Kasei Valles are a giant system of canyons in Mare Acidalium and Lunae Palus quadrangles on Mars, centered at 24.6° north latitude and 65.0° west longitude. They are long and were named for the word for "Mars" in Japanese. This is one of the largest outflow channel systems on Mars. Geography This huge system is 300 miles wide in some places. In contrast, Earth's Grand Canyon is only 18 miles wide. It is one of the longest continuous outflow channel systems on Mars. The Kasei Valles system begins in Echus Chasma, near Valles Marineris. It runs initially northward, then turns eastward and appears to empty into Chryse Planitia, not far from where Viking 1 landed. At around 20° north latitude the system splits into two channels, called Kasei Vallis Canyon and North Kasei Channel. These branches recombine at around 63° west longitude, forming a large island between the channels known as Sacra Mensa. Some parts of the Kasei Valles are 2–3 km deep. Like ...

Valles Marineris
Valles Marineris (; Latin for '' Mariner Valleys'', named after the ''Mariner 9'' Mars orbiter of 1971–72 which discovered it) is a system of canyons that runs along the Martian surface east of the Tharsis region. At more than long, wide and up to deep, Valles Marineris is one of the largest canyons of the Solar System, surpassed in length only by the rift valleys of the mid-ocean ridge system of Earth. Valles Marineris is located along the equator of Mars, on the east side of the Tharsis Bulge, and stretches for nearly a quarter of the planet's circumference. The canyon system starts in the west with Noctis Labyrinthus; proceeding to the east are Tithonium and Ius chasmata, then Melas, Candor and Ophir chasmata, then Coprates Chasma, then Ganges, Capri and Eos chasmata; finally it empties into an outflow channel region containing chaotic terrain that ends in the basin of Chryse Planitia. It has been recently suggested that Valles Marineris is a large tectonic "crack" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vallis Rheita
Vallis Rheita is a linear valley on the near side of the Moon. It is located in the southeastern quadrant, and is oriented radially to Mare Nectaris. This valley appears to share a common origin with the Vallis Snellius to the northeast, as both are oriented radially with Mare Nectaris. The center of the valley lies at selenographic coordinates , and it has a length of 445 km. At its maximum extent this valley has a width of about 30 km, but it narrows to 10 km at the southeastern extreme. It is the second longest such valley on the near side of the Moon, being exceeded only by Vallis Snellius. Vallis Rheita has been eroded by a series of impacts, and several notable craters lie along the length of this valley. Near the northwestern end is the crater Rheita, for which this formation was named. Further to the southeast is the crater Young, nearly centered across the valley. Next to Young is Young D, also lying across the valley but less distorted by the rift. Further southeast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
