What type of boundary occurs along the mid ocean ridge?
The mid-ocean ridge is formed along a divergent or constructive plate boundary between two plates of oceanic crust. A classic example is the Mid-Atlantic Ridge where the Eurasian and African Plates are moving away from the North and South American Plates.
What is the difference between a rift valley and a mid ocean ridge and what kinds of boundaries do they form at?
A subduction zone occurs at convergent plate margins where an oceanic plate is going underneath a continental plate or a less dense oceanic plate. A mid-ocean ridge is a divergent plate boundary on the ocean floor with a mountain range and a rift running through the center of it. Sea floor spreading also occurs at mid ocean ridges.
Most movement occurs along narrow zones between plates where the ... Plate boundary zones -- broad belts in which boundaries are not well ... Africa, is but one segment of the global mid-ocean ridge system that encircles the Earth. ... Some of these rifting events were accompanied by volcanic activity.
The tectonic process that takes place along mid-ocean ridges is called seafloor spreading. The mid-ocean ridge is formed when magma rises up to the surface at a divergent boundary. The oceanic plates on either side of the ridge are pushed apart as the magma flows in and this causes the seafloor to spread.
