what type of plate boundary is found in the middle of the atlantic ocean?
divergent boundary
the mid-atlantic ridge (mar) is a mid-ocean ridge, a divergent tectonic plate or constructive plate boundary located along the floor of the atlantic ocean, and part of the longest mountain range in the world. in the north atlantic, it separates the eurasian and north american plates, and in the south atlantic, it separates the african and south american plates. the ridge extends from a junction with the gakkel ridge (mid-arctic ridge) northeast of greenland southward to the bouvet triple junction in the south atlantic. although the mid-atlantic ridge is mostly an underwater feature, portions of it have enough elevation to extend above sea level. the section of the ridge that includes iceland is known as the reykjanes ridge. the ridge has an average spreading rate of about per year.

where plate boundaries occur within the continental lithosphere, deformation is spread out over a much larger area than the plate boundary itself. in the case of the san andreas fault continental transform, many earthquakes occur away from the plate boundary and are related to strains developed within the broader zone of deformation caused by major irregularities in the fault trace (e.g., the "big bend" region). the northridge earthquake was associated with movement on a blind thrust within such a zone. another example is the strongly oblique convergent plate boundary between the arabian and eurasian plates where it runs through the northwestern part of the zagros mountains. the deformation associated with this plate boundary is partitioned into nearly pure thrust sense movements perpendicular to the boundary over a wide zone to the southwest and nearly pure strike-slip motion along the main recent fault close to the actual plate boundary itself. this is demonstrated by earthquake focal mechanisms.
