Valles Marineris, the largest canyon system on Mars, shown in a composite of images taken by the Viking 1 and 2 orbiters. The system extends east-west for about 4,000 km (2,500 miles); individual canyons are typically 200 km (125 miles) across.

What is the longest valley in the world?
Answer. Rift valley is the longest valley in the world.
How long is Rift Valley?
East African Rift System, also called Afro-Arabian Rift Valley, one of the most extensive rifts on Earth’s surface, extending from Jordan in southwestern Asia southward through eastern Africa to Mozambique. The system is some 4,000 miles (6,400 km) long and averages 30–40 miles (48–64 km) wide.
Which is the longest rift valley of the world which lakes are formed here?
Western or Albertine Rift Valley lakes
The lakes of the Western or Albertine Rift, with Lake Victoria, include the largest, deepest, and oldest of the Rift Valley Lakes. They are also referred to as the Central African lakes.
Which rift is the second largest in the world?
Lake Tanganyika is the world’s second-deepest and second-biggest (by volume of freshwater) lake in the world. Only Lake Baikal is deeper and holds more water. Like many freshwater Rift Valley lakes, Lake Tanganyika is home to hundreds of endemic species of cichlid fish.
Which location is on a major rift valley?
The most well-known rift valley on Earth is probably the so-called “Great Rift Valley System” which stretches from the Middle East in the north to Mozambique in the south. The area is geologically active, and features volcanoes, hot springs, geysers, and frequent earthquakes.
What is the famous Valley?
Yosemite Valley (United States)
Stretching approximately 7.5 miles, Yosemite Valley is located in the Sierra Nevada mountain range of Central California. Formed by glaciers over thirty million years ago, it is most famous for its sheer granite cliffs.
What is the biggest valley in the US?
The Central Valley is a flat valley that dominates the interior of California. It is 40 to 60 miles (60 to 100 km) wide and stretches approximately 450 miles (720 km) from north-northwest to south-southeast, inland from and parallel with the Pacific coast.

Which planet in our solar system has the longest valley discovered to date?
Introducing: Mercury’s Great Valley. The vast scar on the surface of the planet closest to the sun is 250 miles wide, 600 miles long and 2 miles deep, making it the largest valley on the planet, according to a press release from the American Geophysical Union.
Why is Great Rift Valley important?
The system of rift valleys that characterizes the African continent represents a perfect environment to understand the evolution of mankind; for the important paleoanthropological discoveries in Ethiopia, Kenya, Tanzania, Uganda and Zaire, the African rift valleys are indeed considered the “cradle of mankind”, that is …
Why Rift Valley is found between two block mountains?
A rift valley is a linear shaped lowland between several highlands or mountain ranges created by the action of a geologic rift or fault. A rift valley is formed on a divergent plate boundary, a crustal extension or spreading apart of the surface, which is subsequently further deepened by the forces of erosion.
Who lives in the Great Rift Valley?
An estimated 1,000 to 1,500 Hadza live in the central Great Rift Valley and the surrounding plains in north-central Tanzania, where they subsist almost entirely off the land: hunting animals, foraging for roots and fruit, gathering honey.
Why most Rift Valley lakes are salty?
The rains chemically interact with rift terrains, which are dominated with natrocarbonatitic volcanic materials, thus transporting dissolved salts to the lakes. In addition, hot springs around the shores of these lakes carry significant salinity loads into the lakes.
Which is the deepest lake in East Africa?
the deepest of all African lakes and the second deepest lake in the world; and.

Why are Rift Valley lakes rising?
The recent rises, though, are directly associated with above-average rainfall. The lakes have been even higher in the past, and with rainfall in the Rift Valley Basin being on a rising rainfall trend, higher lake levels can be expected in the future.
