It is thought to be the site of upwelling new ocean floor material from Earth's mantle, from which ocean floors are gradually spreading out laterally.The Atlantic ridge is the most striking bottom relief feature of the ATLANTIC OCEAN.. A German oceanographic vessel, Meteor, discovered the ridge. Educational coverage of an expedition to the Mid-Atlantic Ridge aboard the research vessel Atlantis and the submersible Alvin for teachers and students. The ridge has a deep rift valley along its crest between 1,000m and 3,000m deep, which for perspective, is similar in size to the Grand Canyon. The Mid Atlantic ridge is roughly equidistant from the continents of Europe, Africa and the Americas.

In contrast, the East Pacific Rise spreads fast, at rates of 6 to 16 centimeters (3 to 6 inches) per year. The Mid-Atlantic Ridge (MAR) is a mid-ocean ridge, a divergent tectonic plate boundary located along the floor of the Atlantic Ocean, and the longest mountain range in the world.

The Mid-Atlantic Ridge, which splits nearly the entire Atlantic Ocean north to south, is probably the best-known and most-studied example of a divergent-plate boundary. (Illustration adapted from the map This Dynamic Planet. The Mid-Atlantic Ridge is composed of discrete spreading segments that are tens of kilometers long, and offset by transform faults and nontransform offsets. The axis of the Mid-Atlantic Ridge is marked by a major rift valley 1 to 1.5 kilometers deep, a central floor 4 to 15 kilometers across, and ranges of crestal mountains on each side of the The Mid-Atlantic Ridge runs down the center of the Atlantic Ocean. It spread apart at rates of 2 to 5 cm per year, and at these relatively slow spreading rates, the ridge has a deep rift valley along its crest. The rift valley is 1 to 3 km deep, about the depth and width of the Grand Canyon.
