Practice FRQ
Plate-tectonic theory states that the Earth’s lithosphere is broken into very slowly moving pieces or plates. Plate movements over vast stretches of time have led to the current orientation of our continents and oceans. Individual events along plate boundaries, such as earthquakes and volcanic eruptions, pose periodic threats to human activity and ecosystems. The “Ring of Fire” is a term that describes the location of increased seismic and volcanic activity around the margins of the Pacific Ocean basin. On the map, each dot represents a volcano or an earthquake.

Japan, Indonesia, and the Philippines are examples of volcanic island chains that have formed along subduction zones between plates in the western Pacific.- Describe what happens when two tectonic plates collide along a subduction zone.
- Explain how subduction leads to volcanic activity.
