The Pacific Ocean's Ring of Fire contains a chain of volcanoes roughly 25,000 miles long, formed where the Pacific tectonic plate slides against or collides with surrounding plates.
Notes on verification
Confirmed by NOAA, Wikipedia, and Britannica with consistent figures on length (~25,000 miles/40,000 km) and tectonic plate interactions forming the belt.
