“Mid-ocean ridges are the topographic manifestation of where the Earth’s tectonic plates separate and spread apart and new oceanic crust is created. The Mid-Cayman Rise is an example of one of these ridges and forms part of the boundary between the North American and Caribbean tectonic plates.” Quoted from the Ocean Explorer website.
Profiles of Mt Dent on west of the Mid-Cayman Spreading Center (red) and Mt Everest (yellow) shown at the same scale. Mt Dent is clearly a big (undersea) mountain.

The Kane oceanic core complex from 23oN on the Mid-Atlantic Ridge. This is one of the most spectacular core complexes we’ve discovered with the smooth detachment fault surface clearly visible. The cross section shows what the crust is likely made of: green represents mantle peridotite; blue represents frozen mantle melts forming gabbro intrusion and magenta represents the basalt lavas and sheeted dikes that normally overly the gabbros.
