THE Mid-Oceanic Ridge, a broad fractured arch more than 40,000 miles long, is the largest tectonic feature on the surface of the Earth. Associated with the centre of the ridge over much of its length is an axial fracture or rift which is the locus of shallow earthquakes. An extension of...

Oceanic crustHigh-resolution images covering large areas of the seafloor reveal numerous discontinuities along the mid-ocean ridge. These discontinuities occur at a range of scales (10–1,000 km) and define a fundamental segmentation of seafloor spreading centres. Some are transient; others persist ...
Sea Floor Spreading: The Mid-Oceanic Ridge The East Pacific Rise and the Mid-Atlantic Ridge are parts of the mid-ocean ridge, the longest mountain chain in the world. During the mid 1900’s, scientists mapped the mid-ocean ridge using sonar. Most of the mountains are below the surface of...
