Top View Of The Ocean Floor Surrounding A Mid Ocean Ridge

The nearly continuous global mid ocean ridge system snakes across the earth s surface like the seams on a baseball.

Top view of the ocean floor surrounding a mid ocean ridge.

The average depth to the crest top of the ridge is 2500 m but it rises above sea level in iceland and is more than 4000 m deep in the cayman trough. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the. Bathymetric image of the east pacific rise a mid oceanic ridge located along the floor of the pacific ocean. Here the earth s crust is spreading creating new ocean floor and literally renewing the surface of our planet.

Much of the mid ocean ridge system remains unexplored because of the challenges involved in reaching these inhospitable zones. Mid ocean ridges are geologically important because they occur along the kind of plate boundary where new ocean floor is created as the plates spread apart. A mid ocean ridge mor is a seafloor mountain system formed by plate tectonics it typically has a depth of 2 600 meters 8 500 ft and rises about two kilometers above the deepest portion of an ocean basin this feature is where seafloor spreading takes place along a divergent plate boundary the rate of seafloor spreading determines the morphology of the crest of the mid ocean ridge and its. Across iceland all the way to the bottom of the atlantic near.

The mid ocean ridge is the most extensive chain of mountains on earth stretching nearly 65 000 kilometers 40 390 miles and with more than 90 percent of the mountain range lying in the deep ocean. Image courtesy of haymon et al noaa oe whoi the mid ocean ridge is a continuous range of undersea volcanic mountains that encircles the globe almost entirely underwater. Older crust is recycled back into the mantle elsewhere on the globe typically where plates collide. The mid oceanic ridge system is the longest mountain range in the world.

The global mid ocean ridge system is the largest single volcanic feature on the earth encircling it like the seams of a baseball. Thus the mid ocean ridge is also. A mid ocean ridge is made by a divergent boundary. Then 40 000 miles of ocean floor making the earth look like it has a series of zippers.

The mid ocean ridges of the world are connected and form a single global mid oceanic ridge system that is part of every ocean. It is a central feature of seafloor terrain that is more varied and more spectacular than almost anything found on dry land and includes a collection of volcanic ridges rifts fault zones and other geologic. All the world s oceans have a mid ocean ridge beneath them. A mid ocean ridge mor is a seafloor mountain system formed by plate tectonics it typically has a depth of 2 600 meters 8 500 ft and rises about two kilometers above the deepest portion of an ocean basin this feature is where seafloor spreading takes place along a divergent plate boundary the rate of seafloor spreading determines the morphology of the crest of the mid ocean ridge and its.
