Examples of volcanoes found along divergent plate boundaries include Krafla Volcano in Iceland, as well as Erta Ale and Oldoinyo Lengai in Africa. The process of volcanic formation along divergent boundaries is called spreading center volcanism.Know More
Plate boundaries are classified according to the type of plate movement that occurs in these areas. Divergent plate boundaries are regions where two adjacent plates move apart. The most prominent divergent boundaries are the Mid-Atlantic Ridge and the East African Rift Zone.
Krafla Volcano is situated in the northern section of Iceland, a volcanic country that traverses the Mid-Atlantic Ridge. Erta Ale and Oldoinyo Lengai are located within the East African Rift Zone. These volcanoes are created due to rifting, where faults along the surface continue to widen and spread out. The magma that rises to fill the cracks erupt, which results to volcanic formation.Learn more about Volcanoes
Based upon the number of large explosions over the past 10,000 years, the most active explosive volcanoes are, in order: Shiveluch in Russia, Pel?e in Martinique, Cotopaxi in Ecuador, Katla in Iceland, Arenal in Costa Rica, Hekla in Iceland, Ibusuki Volcanic Field in Japan, Taupo in New Zealand, Vesuvius in Italy and Avachinsky in Kamchatka. Shiveluch has erupted the most, 43 times, compared to 22 times for Pel?e.Full Answer >
The three types of plate boundaries are divergent plate boundaries, convergent plate boundaries and transform plate boundaries. Divergent plate boundaries occur in places where two plates are moving away from each other. When two plates are being forced together, they are called convergent plate boundaries. Finally, transform plate boundaries occur in places where two plates are moving in opposite directions and rubbing against each other.Full Answer >
Most of the world's volcanoes are located around the edges of the Ring of Fire. Even though the Ring of Fire includes three continents, the volcanoes in Asia tend to be the most active.Full Answer >
Volcanic vents allow the Earth to release built up gases from the heat and pressure emanating from its core. Magma rises towards the surface, and as the pressure builds the magma seeks outlets through which to flow. The higher the pressure build-up, the greater the volcanic explosion.Full Answer >
