Volcanoes form at two different types of boundaries between tectonic plates on the Earth's crust: subducting and constructive. Subducting boundaries appear where one plate slides beneath the surface of the other while co... More »

Volcanoes are found where the tectonic places that make up the Earth's surface are either pushing together or pulling apart. They are also found away from plate boundaries at "hot spots," where magma pushes through the E... More »

Commonly, volcanoes form at points where the Earth's crust is thinnest. This is normally near fault lines, but has been known to occur in the middle of tectonic plates or even in subduction zones, where one plate is push... 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 »

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 »

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 »
