A bathymetric map of the Mid-Atlantic Ridge (shown in light blue in the middle of the Atlantic Ocean) 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.

The Mid-Atlantic Ridge is located at the juncture of crustal plates that form the floor of the Atlantic Ocean; it is considered a "slow-spreading" ridge by earth scientists. Running along the crest of the ridge is a long valley that is about 50 to 75 miles (80 to 120 km) wide.

Two well-studied mid-ocean ridges within the global system are the Mid-Atlantic Ridge and the East Pacific Rise. The Mid-Atlantic Ridge runs down the center of the Atlantic Ocean, slowly spreading at a rate of 2 to 5 centimeters (0.8 to 2 inches) per year and forming a rift valley that is about the depth and width of the Grand Canyon.

There are more ridges whose names don't fit: The Galápagos Ridge runs from the East Pacific Rise to Cntral America, and the northern continuation of the Mid-Atlantic Ridge is called Reykjanes Ridge south of Iceland, Mohns Ridge ...

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.

The Mid-Atlantic Ridge, which stretches for thousands of miles in the Atlantic Ocean, is the longest mountain chain on Earth. Understanding the geologic processes at the ridge, mapped here using satellite data, was crucial as scientists developed the theory of plate tectonics.

Mid-Atlantic Ridge: This prominent ridge runs down the center of the Atlantic Ocean, separating the Eurasian and North American plates in the north, and the African and South American plates in the south. It is a slow-spreading ridge, characterized by a …

The first discovered mid-ocean ridge was the Mid-Atlantic Ridge, which is a spreading center that bisects the North and South Atlantic basins; hence the origin of the name 'mid-ocean ridge'. Most oceanic spreading centers are not in the middle of their hosting ocean basis but regardless, are traditionally called mid-ocean ridges.
