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 ...
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.
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 largest and best known undersea mountain range is a mid-ocean ridge, the Mid-Atlantic Ridge. [1]
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 .
Physiographic world map with mountain ranges and highland areas in brown, pink, and gray. This is a list of mountain ranges on Earth and a few other astronomical bodies.First, the highest and longest mountain ranges on Earth are listed, followed by more comprehensive alphabetical lists organized by continent.
In 1960, the American geophysicist Harry H. Hess hypothesized that the seafloor was spreading from the mid-ocean ridge system. [6] With support from the maps of the sea floor, and the recently developed theory of plate tectonics and continental drift, Hess was able to prove that the Earth's mantle continuously released molten rock from the mid ...
The elements of an active and growing oceanic basin include an elevated mid-ocean ridge, flanking abyssal hills leading down to abyssal plains and an oceanic trench. Changes in biodiversity, floodings and other climate variations are linked to sea-level, and are reconstructed with different models and observations (e.g., age of oceanic crust ...
