WebIceland is a 1 km high, 450x300 km basaltic shield on the mid-ocean ridge in the northeast Atlantic Ocean. It comprises over 100 active or extinct volcanoes and has been extensively studied by Earth scientists for several decades. Iceland must be understood in the context of the broader structure and tectonic history of the northeast Atlantic. WebWhile most volcanoes occur at mid-ocean ridges; however, there are some volcanoes that form on land. Some volcanoes form away from the point of tectonic contact, and are known as hotspots. They are formed from rising magma intrusions known as mantle plumes. Hotspots are magma chambers regions that are stationary under the Earth’s crust. laxative headache
