The deepest point in the Atlantic is the Puerto Rico Trench, not the Mid-Atlantic Ridge, which is a mountain range rising above the abyssal plain.

The Mid-Atlantic Ridge is a divergent boundary, not convergent. Plates move apart there, creating new crust, rather than colliding and subducting.

The Mid-Atlantic Ridge has a prominent central rift valley along its crest, formed by the spreading of tectonic plates, so it is not a smooth continuous range.

The Mid-Atlantic Ridge is a divergent plate boundary where the North American and Eurasian plates move apart, allowing magma to rise and form new oceanic crust.

The Mid-Atlantic Ridge was discovered by oceanographic expeditions in the 19th century, long before space travel. It is not visible from space without mapping technology.

The German Meteor expedition (1925–1927) used echo sounding to produce the first detailed bathymetric map of the Mid-Atlantic Ridge, revealing its rugged topography.

Marie Tharp and Bruce Heezen produced the first detailed map of the Atlantic ocean floor in the 1950s, revealing the full extent of the Mid-Atlantic Ridge.
