The Ocean Floor Is Created Along Mid Ocean Ridges

Along the crest of mid ocean ridges.

The ocean floor is created along mid ocean ridges.

The majority of the system is underwater with an average water depth to the top of the ridge of 2 500 meters 8 200 feet. Terms in this set 56 a method of mapping the topography of the ocean floor along a strip up to 60 km wide. Mid ocean ridges occur along divergent plate boundaries where new ocean floor is created as the earth s tectonic plates spread apart. This feature is where seafloor spreading takes place along a divergent plate boundary.

The mid ocean ridge is the longest mountain range on earth. Because newly formed lithosphere is hotter and therefore less dense than the surrounding rocks which of the following is not part of an ophiolite complex. It typically has a depth of 2 600 meters and rises about two kilometers above the deepest portion of an ocean basin. Basalt the once molten rock that makes up most new oceanic crust is a fairly magnetic substance and scientists began using magnetometers to measure the magnetism of the ocean floor in the 1950s.

The correct order of seafloor features from the coast to the mid ocean ridge is. The global mid ocean ridge system is the largest single volcanic feature on the earth encircling it like the seams of a baseball. Shelf slope rise. The magnetism of mid ocean ridges helped scientists first identify the process of seafloor spreading in the early 20th century.

Why are mid ocean ridges elevated compared to the surrounding ocean floor. What would happen to earth if ocean floor were created at divergent boundaries at a faster rate than it is destroyed at convergent boundaries. As the plates separate molten rock rises to the seafloor producing enormous volcanic eruptions of basalt. The earth would increase in volume.

One of the proof is that its peaks are even higher than the alpine s peaks. New sea floor is formed along mid ocean ridges. Used to determine ocean structure beneath the sea floor. The abyssal plain stretched for miles deep below the surface of the ocean.

The total length of the ridge is as much as circling around the world to times. What they discovered was that the magnetism of the ocean floor around mid ocean ridges was divided into matching stripes on either side of the ridge. Residual unmelted crustal lithosphere. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the.

A mid ocean ridge or mid oceanic ridge is an underwater mountain range formed by plate tectonics. Older crust is recycled back into the mantle elsewhere on the globe typically where plates collide. Long narrow steep sided depression in the seafloor formed where one crustal plate sinks beneath another. Area where new ocean floor is formed when lava erupts through cracks in earth s crust.

Here the earth s crust is spreading creating new ocean floor and literally renewing the surface of our planet. The rate of seafloor spreading determines the morphology of the crest of the mid ocean ridge and its width in an ocean basin.
