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, ... More »

When tectonic plates collide and form a convergent boundary, their interaction can produce earthquakes, volcanic activity, underwater trenches and mountain formations. Any resulting geologic events on the Earth's surface... More »

A convergent plate boundary occurs when a collision of tectonic plates causes one plate to slide over the top of another. There are three examples of convergent plate boundaries that occur as the result of continental an... More »

Plate boundaries are the weakest points in the Earth's crust, which leads to cracks that allow magma to seep through and develop volcanoes, according to NEWTON. These areas are called "subduction zones." Subduction zones... More »

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 sp... More »

Volcanic arcs are formed when an oceanic plate is forced under a continental plate and the water-soaked crust melts as it's forced below the ocean floor, creating magma that feeds volcanoes on the continental side of the... More »

There are three types of plate boundaries: convergent, when tectonic plates come together; divergent, when tectonic plates are moving away from each other; and transform, when two plates are sliding past one another. Eac... More »
