WebJan 11, 2024 · Volcanoes erupt at mid-ocean ridges, such as the Mid-Atlantic ridge. Seafloor spreading creates new seafloor in the rift valleys. This type of volcanism makes all of the ocean floor! Where a hotspot is located along the ridge, such as at Iceland, volcanoes grow high enough to create islands ( Figure below).
WebJun 20, 2024 · Mid-ocean ridge volcanoes form where two plates are moving apart. As the plates move apart, cracks form in the crust. Magma from the mantle surges up these cracks, and erupts onto the surface, forming new crust. Mid-ocean ridges are very difficult to study because they are usually deep underwater. Where are volcanoes located? bke4life.comWebThe 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.
