Most mid-ocean ridges of the world are connected and form the Ocean Ridge, a global mid-oceanic ridge system that is part of every ocean, making it the longest mountain range in the world. The continuous mountain range is 65,000 km (40,400 mi) long (several times longer than the Andes , the longest continental mountain range), and the total ...
Undersea mountain ranges are mountain ranges that are mostly or entirely underwater, and specifically under the surface of an ocean. If originated from current tectonic forces, they are often referred to as a mid-ocean ridge. In contrast, if formed by past above-water volcanism, they are known as a seamount chain.
The Mid-Atlantic Ridge is a mid-ocean ridge (a divergent or constructive plate boundary) located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world. In the North Atlantic, the ridge separates the North American from the Eurasian plate and the African plate, north and south of the Azores triple junction.
The Andes range consist of hundreds of mountain peaks.. The world's longest above-water mountain range is the Andes, [1] about 7,000 km (4,300 mi) long. The range stretches from north to south through seven countries in South America, along the west coast of the continent: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina.
In 2015, researchers found that the volcano's structure bore patterns of magnetic striping on either side, indicating that the volcano is likely a hybrid of a mid-ocean ridge and a shield volcano. Geologic data also indicated that Tamu Massif formed at the junction of three mid-ocean ridges, which was a highly unusual occurrence. [14]
Viaud Ridge is an underwater mountain range in the Indian Ocean [1] located in the Laccadive Sea. [2] The neighbouring land masses are Sri Lanka, [1] [3] with the capital Colombo 650 kilometers to the north-north-east, [1] [4] [5] the southern tip of India to the north and the Maldives to the west, at the latitude of Addu Atoll.
The Gorringe Ridge is a seamount in the Atlantic Ocean. It is located about 130 miles (110 nmi; 210 km) west of Portugal , between the Azores and the Strait of Gibraltar along the Azores–Gibraltar fault zone .
The transverse ridge separates the present trench from an 800 km (500 mi)-long aseismic valley where the Romanche transform was located until about 10–8 Ma. This transform migration was preceded by a process 25–17 Ma during which the Miocene shallow-water platform mentioned above reached sea level as the transverse ridge was first uplifted ...
