iceland is a belt of volcanoes/hotspots along the mid ocean ridge, it isn't just mostly volcanoes, it is a volcano itself
The Atlantic Ocean surrounds Iceland.
No, most of the volcanoes along the mid-ocean ridge do not rise above the ocean's surface. These submarine volcanoes are typically under the water and form part of the continuous volcanic activity that occurs along the ocean ridges. Only a few volcanoes along the mid-ocean ridge, such as Iceland, rise above the ocean's surface.
Iceland, an exposed area along the mid-ocean ridge would consist largely of the extrusive igneous rock basalt.
Spreading center volcanism occurs along mid-ocean ridges where tectonic plates are moving apart. The process involves the upwelling of hot magma from the mantle, which creates new oceanic crust as it solidifies upon cooling. This type of volcanism is an important mechanism for plate tectonics and plays a key role in shaping the Earth's lithosphere.
Iceland is an island entirely in the North Atlantic Ocean. The most northerly part of Iceland almost reaches the Arctic Ocean, which is separated from the Atlantic Ocean by the Arctic Circle. Atlantic Ocean

It is a place where volcanism or hot water heated by the underlying magma erupts on the ocean floor.
