How do volcanoes form along the mid-ocean ridge?

because two major plates meet there and the contact between both of them (imagine how big they might be) cause the huge mountain ranges in many cases with volcanoes.How do volcanoes form along the mid-ocean ridge?
Since it is located at a divergent or lateral plate boundary, magma from the mantle flows out to the Earth's surface through a crack found on the Earth's crust. The magma cools and solidifies upon reaching the Earth's surface, forming a new landform made of magma or igneous rocks( derived from solidified magma) such as a volcano, or sometimes, a volcanic island, such as Hawaii. This usually occurs at ocean basins.
