WebThe mountains forming the ridge reach a width of 1,000 miles. These mountains sometimes reach above sea level, thus forming the islands or island groups of the Azores, Ascension, St. Helena, and Tristan da Cunha, among others. Running along the crest of the Mid-Atlantic Ridge is a long valley that is about 50 to 75 miles (80 to 120 km) wide. The ridge sits atop a geologic feature known as the Mid-Atlantic Rise, which is a progressive bulge that runs the length of the Atlantic Ocean, with the ridge resting on the highest point of this linear bulge.
