List Of Valleys On Mars
Valles (singular Vallis (planetary geology), vallis) on Mars are similar to valleys on Earth. Some features that take this title may be better described as canyons or chasmata; see List of Chasmata on Mars. Coordinates are given as planetocentric latitude with east longitude. Large valles are named for the words for "Mars" or "star" in various languages, while small ones are named for rivers.

Vallis (planetary Geology)
''Vallis'' or ''valles'' (plural ''valles'' ) is the Latin word for ''valley''. It is used in planetary geology to name landform features on other planets. Scientists used ''vallis'' for old river valleys they discovered when they sent the first probes to Mars. The Viking Orbiters caused a revolution in our ideas about water on Mars; finding huge river valleys in many areas. Space craft cameras showed that floods of water broke through dams, carved deep valleys, eroded grooves into bedrock, and traveled thousands of kilometers. Some valles on Mars (Mangala Vallis, Athabasca Vallis, Granicus Vallis, and Tinjar Valles) clearly begin at graben. On the other hand, some of the large outflow channels begin in rubble-filled low areas, called chaos or chaotic terrain. It has been suggested that massive amounts of water were trapped under pressure beneath a thick cryosphere (layer of frozen ground), then the water was suddenly released, perhaps when the cryosphere was broken by a fault. ...

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, form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Quechua Language
Quechua (, ; ), usually called ("people's language") in Quechuan languages, is an Indigenous languages of the Americas, indigenous language family spoken by the Quechua peoples, primarily living in the Peruvian Andes. Derived from a common ancestral language, it is the most widely spoken Pre-Columbian era, pre-Columbian language family of the Americas, with an estimated 8–10 million speakers as of 2004.Adelaar 2004, pp. 167–168, 255. Approximately 25% (7.7 million) of Peruvians speak a Quechuan language. It is perhaps most widely known for being the main language family of the Inca Empire. The Spanish encouraged its use until the Peruvian War of Independence, Peruvian struggle for independence of the 1780s. As a result, Quechua variants are still widely spoken today, being the co-official language of many regions and the second most spoken language family in Peru. History Quechua had already expanded across wide ranges of the central Andes long before the expansion of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auqakuh Vallis
Auqakuh Vallis is an ancient river valley in the Syrtis Major quadrangle on Mars, located at 30.4° north latitude and 299.9° west longitude. It is 312 km long, and is named for the word for 'Mars' in Quechua (Inca). Buttes Many places on Mars have buttes that are similar to buttes on Earth, such as the famous ones in Monument Valley, Utah Utah ( , ) is a state in the Mountain West subregion of the Western United States. Utah is a landlocked U.S. state bordered to its east by Colorado, to its northeast by Wyoming, to its north by Idaho, to its south by Arizona, and to it .... Buttes are formed when most of a layer(s) of rocks are removed from an area. Buttes usually have a hard, erosion-resistant cap rock on the top. The cap rock causes the top of a butte to be flat. An example of a butte in the Syrtis Major quadrangle is shown in a picture on this page. References Valleys and canyons on Mars Syrtis Major quadrangle {{Mars-stub ...

Cerberus Fossae
The Cerberus Fossae are a series of semi-parallel fissures on Mars formed by faults which pulled the crust apart in the Cerberus region. They are 1235 km across and centered at 11.28 °N and 166.37 °E. Their northernmost latitude is 16.16 °N and their southernmost latitude 6.23 °N. Their easternmost and westernmost longitudes are 174.72 °E and 154.43 °E, respectively. They can be seen in the Elysium quadrangle. Ripples seen at the bottom of the faults are sand blown by the wind. Numerical modeling of the forces in the crust of Mars suggest that the underlying cause for the faulting is the deformation caused by the Tharsis volcanoes to the east. The faults are quite young, cutting through pre-existing features such as the hills of the Tartarus Montes and the lava apron southeast of Elysium Mons. The formation of the fossae was suspected to have released pressurized underground water, previously confined by the cryosphere, with flow rates up to 2 × 106 m3s−1, leadin ...

Athabasca River
The Athabasca River (French: ''Rivière Athabasca'') is a river in Alberta, Canada, which originates at the Columbia Icefield in Jasper National Park and flows more than before emptying into Lake Athabasca. Much of the land along its banks is protected in national and provincial parks, and the river is designated a Canadian Heritage River for its historical and cultural importance. The scenic Athabasca Falls is located about upstream from Jasper. Etymology The name ''Athabasca'' comes from the Woods Cree word , which means "herethere are plants one after another", likely a reference to the spotty vegetation along the river. Course The Athabasca River originates in Jasper National Park, in an unnamed lake at the toe of the Columbia Glacier within the Columbia Icefield, between Mount Columbia, Snow Dome, and the Winston Churchill Range, at an elevation of approximately . It travels before draining into the Peace-Athabasca Delta near Lake Athabasca south of Fort Chipewyan. Fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Athabasca Valles
The Athabasca Valles are a late Amazonian-period outflow channel system in the central Elysium Planitia region of Mars, located to the south of the Elysium Rise. They are part of a network of outflow channels in this region that are understood to emanate from large fissures in the Martian surface rather than the chaos terrains that source the circum- Chryse outflow channels. The Athabasca Valles in particular emanate from one of the Cerberus Fossae fissures and flow downstream to the southwest, constrained to the south by a wrinkle ridge for over 100 km, before debouching into the Cerberus Palus volcanic plain. The Athabasca Valles are widely understood to be the youngest outflow channel system on the planet. Although researchers generally agree that the valley was formed by the catastrophic outpouring from the southernmost Cerberus Fossae fissure, the scientific community has not reached a consensus on the precise formation mechanism behind the Athabasca Valles - both i ...

Asopus
Asopus (; grc, Ἀ̄σωπός ''Āsōpos'') is the name of four different rivers in Greece and one in Turkey. In Greek mythology, it was also the name of the gods of those rivers. Zeus carried off Aegina, Asopus' daughter, and Sisyphus, who had witnessed the act, told Asopus that he could reveal the identity of the person who had abducted Aegina, but in return Asopus would have to provide a perennial fountain of water at Corinth, Sisyphus' city. Accordingly, Asopus produced a fountain at Corinth, and pursued Zeus, but had to retreat for fear of Zeus' terrible thunderbolt. Rivers The rivers in Greece #Asopos (Boeotia), a river of Boeotia originating on Mt. Cithaeron and flowing through the district of Plataea into the Euripus Strait. #Asopos (Corinthia) or Phliasian Asopus, originating in Phliasian territory and flowing through Sicyonian territory into the Gulf of Corinth near Sicyon.

Arno River
The Arno is a river in the Tuscany region of Italy. It is the most important river of central Italy after the Tiber. Source and route The river originates on Monte Falterona in the Casentino area of the Apennines, and initially takes a southward curve. The river turns to the west near Arezzo passing through Florence, Empoli and Pisa, flowing into the Tyrrhenian Sea at Marina di Pisa. With a length of , it is the largest river in the region. It has many tributaries: Sieve at long, Bisenzio at , Ombrone Pistoiese at , and the Era, Elsa, Pesa, and Pescia. The drainage basin amounts to more than and drains the waters of the following subbasins: *The Casentino, in the province of Arezzo, formed by the upper course of the river until its confluence with the Maestro della Chiana channel. *The Val di Chiana, a plain drained in the 18th century, which until then had been a marshy area tributary of the Tiber. *The upper Valdarno, a long valley bordered on the east by t ...
