How do volcanoes form along mid ocean ridges

WebBasalts found at oceanic islands are geochemically distinct from those found at mid-ocean ridges and volcanoes associated with subduction zones (island arc basalts). " Ocean island basalt " is also similar to basalts found throughout the oceans on both small and large seamounts (thought to be formed by eruptions on the sea floor that did not ... WebThe majority of volcanism in Iceland occurs along volcanic rift zones that cut through the centre of the island. At constructive plate boundaries, also known as divergent boundaries, tectonic plates move away from one another to produce volcanoes.
