Ocean Ridges are underwater physical features formed along the two divergent boundaries. When two divergent boundaries are adjacent to each other and they keep diverging, ocean ridges form as a result of increasing gap between them which ultimately results in the volcanic eruption which later spreads, cools down and forms as ridges under the oceanic surface while repetition of this process leads to the formation of large oceanic ridges.
It is often noticed that, the age of the ridges keeps on increasing as one moves from top to bottom.
A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.
A submarine canyon is a steep-sided valley that is cut into the bed's of the continental slopes and is an extension of the continental shelf and gains a height of 5 meters. The submarine canyons are found on the active margins and active margins and turbidity are denser and their erosion is triggered by the underwater landslides.
