More Information

The Ring of Fire is primarily formed by convergent plate boundaries, particularly subduction zones, where one plate moves under another causing volcanic activity. The focus is the point where an earthquake starts beneath the surface, and magma refers to the molten rock beneath the Earth's crust. Surface waves, which travel across the Earth's surface, cause the most damage during an earthquake due to their larger amplitude. Pangea was the supercontinent that existed millions of years ago, and divergent boundaries are where plates move apart, leading to new crust formation.

Tips

Confusing the epicenter with the focus is common. The epicenter is the point directly above the focus on the Earth's surface.
