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
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 >
There are more than 550 active volcanoes in the world, almost all of which are located at convergent tectonic plate boundaries. This includes all of the volcanoes in the Pacific Ring of Fire, such as Japan's Mount Fuji, as well as Mount Saint Helens, Popocafepetl in Mexico and Azul in the Andes Range.Full Answer >
No two volcanoes are exactly the same, as they all have differences in dimensions of their mountains and craters, as well as their relative frequency and type of eruption. Volcanoes come in cinder cone, shield and stratovolcano varieties.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 >
