Which is the deepest valley in the world?
Kali Gandaki has a reputation of the deepest valley in the world. By the village Larjung (at an altitude of about 2550m asl) is valley nearly a kilometer-wide and doesn´t look like the canyon. But directly above him, however, rises eight-thousand Dhaulagiri which it exceeds about 5.5 km.

Why is Valles Marineris so big?
The most agreed upon theory today is that Valles Marineris was formed by rift faults like the East African Rift, later made bigger by erosion and collapsing of the rift walls. It has also been proposed that Valles Marineris was formed by flowing lava.
How long is the Great Rift Valley?
The system is some 4,000 miles (6,400 km) long and averages 30–40 miles (48–64 km) wide. Lake Kivu, located in the western branch of the East African Rift System.

What is the biggest ravine in the world?
The deepest ravine on earth is the Mariana Trench, which is found underwater below the Philippine Plate. The underwater gorge descends 35,827 feet. However, it is still easier to witness the splendor of the Grand Canyon any day than trying to explore the Mariana Trench.
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.
Why 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.
What two planets have no moons?
The answer is no moons at all. That’s right, Venus (and the planet Mercury) are the only two planets that don’t have a single natural moon orbiting them. Figuring out why is one question keeping astronomers busy as they study the Solar System.
What is the big scar on Mars?
A ragged geological scar crosses the belly of Mars. Long enough to reach from New York City to Los Angeles, this great rift in the martian crust is named Valles Marineris, or Mariner Valley. It was discovered in 1972 by the Mariner 9 spacecraft.
How long was Viking 1 on Mars?
The Viking mission was planned to continue for 90 days after landing. Each orbiter and lander operated far beyond its design lifetime. Viking Orbiter 1 continued for four years and 1,489 orbits of Mars, concluding its mission August 7, 1980, while Viking Orbiter 2 functioned until July 25, 1978.
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 …
What will eventually happen if a Rift Valley continues to pull apart?
Earth’s rift valleys
In these instances, not only the crust but entire tectonic plates are in the process of breaking apart to create new plates. If they continue, continental rifts will eventually become oceanic rifts.
Who Discovered the Great Rift Valley?
The Great Rift was discovered almost hundred years ago by an intrepid geologist. John “Jack” Walter Gregory was born in London in 1864.
