Mid Atlantic Ridge (total length of about 60000 km)
... tectonic plates meet at a divergent boundary. There are two processes, ridge-push and slab-pull. Ridge-push occurs when the weight of the ridge pushes the rest of the tectonic plate away from the ridge, often towards a subduction zone. At the subduction zone, "slab-pull" comes into effect. This is s ...
