- The Mid-Atlantic Ridge includes a deep rift valley that runs along the axis of the ridge for nearly its entire length. This rift marks the actual boundary between adjacent tectonic plates, where magma from the mantle reaches the seafloor, erupting as lava and producing new crustal material for the plates.

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.
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 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.

Landforms at a divergent plate boundary include ocean ridges, eg the Mid-Atlantic ridge (where the Eurasian plate and the North Atlantic plate are moving apart from each other under...
Apr 17, 2017 · Description: 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...
Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundaries. When two plates come together, it is known as a convergent boundary.
One of Tharp’s most stunning finds was the Mid-Atlantic Ridge, a gigantic mountain range that spans the Atlantic Ocean. We now know that this ridge marks the boundary where multiple pairs of tectonic plates pull away from one another at a few centimeters per year.
