Final answer:
The type of volcanism associated with the zone of active volcanoes called the Ring of Fire is subduction zone volcanism.
Step-by-step explanation:
The type of volcanism associated with the zone of active volcanoes called the Ring of Fire is subduction zone volcanism. The Ring of Fire is a region where the Pacific tectonic plate is subducting beneath other tectonic plates, causing volcanic activity and earthquakes. Subduction occurs when two tectonic plates collide, and the denser oceanic plate slides beneath the lighter continental plate.
One example of subduction zone volcanism in the Ring of Fire is the Cascadia Subduction Zone off the coast of the United States and Canada. Here, the Juan de Fuca Plate is being subducted beneath the North American Plate, leading to volcanic activity along the Cascade Range, including Mount St. Helens.
Other types of volcanism associated with the Ring of Fire include mid-ocean ridge volcanism and collision zone volcanism, which occur at different plate boundaries within the Ring of Fire.
