Definitions for "Mid-ocean ridge"
Continuous, median, seismic mountain range on the ocean floor, running through the North and South Atlantic oceans, the Indian Ocean, and the South Pacific Ocean.
A continuous, volcanically active mountain range extending through the North and South Atlantic Oceans, the Arctic Ocean, the Indian Ocean, and the South Pacific Ocean. It is a broad, fractured swell with a central rift valley, and usually extremely rugged topography. It is 1-3 km in elevation, about 1500 km in width, and over 84,000 km in length. According to the theory of sea-floor spreading, new oceanic crust is created by volcanic eruptions at the mid-ocean ridge.
mountain range that runs along the ocean bottom formed at the boundaries of oceanic plates. The base is in very deep water and the top may break through the ocean surface to form oceanic islands, such as the Western Azores.
