The Mid-Atlantic Ridge (MAR) is known as a mid-ocean ridge, an underwater mountain system formed by plate tectonics. It is the result of a divergent plate boundary that runs from 87° N – about 333 km (207 mi) south of the North Pole – to 54 °S, just north of the coast of Antarctica. Like other ocean ridge systems, the MAR developed as a consequence...
As noted, the ridge (while mainly underwater) does have islands and island groups that were created by volcanic activity. In the Northern Hemisphere, these include Jan Mayen Island and Iceland (Norway), and the Azores (Portugal). In the Southern Hemisphere, MAR features include Ascension Island, St. Helena, Tristan da Cunha, Gough Island (all UK te...
The ridge was initially discovered in 1872 during the expedition of the HMS Challenger. In the course of investigating the Atlantic for the sake of laying the transatlantic telegraph cable, the crew discovered a large rise in the middle of the ocean floor. By 1925, its existence was confirmed thanks to the invention of sonar. By the 1960s, scientis...
Definition. The Mid-Atlantic Ridge is a continuous mountain range that runs down the center of the Atlantic Ocean, formed by the tectonic activity of divergent plate boundaries.
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.
Definition. The Mid-Atlantic Ridge is a mostly underwater mountain range that runs down the center of the Atlantic Ocean, marking the boundary between the Eurasian and North American tectonic plates in the north, and the African and South American plates in the south.
Mid-Atlantic Ridge. The North American and Eurasian Plates are moving away from each other along the line of the Mid Atlantic Ridge. The Ridge extends into the South Atlantic Ocean between the South American and African Plates.

The Mid-Atlantic Ridge is part of the global mid ocean ridge system. It is a divergent plate boundary where continental plates are moving apart. As the plates separate they are creating the Mid-Atlantic Ridge that separates the two continents.
