The Ring of Fire is a chain of volcanoes and earthquake zones formed primarily where the Pacific tectonic plate converges with surrounding plates, driven mainly by subduction at convergent plate boundaries.
Notes on verification
Corrected 2026-09-06 verification pass F: original fact_text used imprecise 'slides against or collides with' framing. NOAA Ocean Explorer and USGS both describe the mechanism as convergent plate boundaries with subduction (heavier plate subducted under lighter, generating magma and deep trenches). Rewrote fact_text to match NOAA/USGS terminology. Primary source reassigned from NatGeo pacific-ocean (id=123, a generic Pacific Ocean article) to USGS Ring of Fire FAQ (id=2510, the authoritative government primary on the exact topic). NatGeo demoted to verification. Cleared aggregator_dropped_primary_exists flag. Independence score bumped 0.539 -> 0.900.
