Pacific Ring of Fire
The Pacific Ring of Fire is a horseshoe-shaped region in the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur. This area is home to about 75% of the world's active and dormant volcanoes. The Ring of Fire is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and plate movements.
Causes of the Pacific Ring of Fire
The Pacific Ring of Fire is the result of plate tectonics and the movement of several tectonic plates along the edges of the Pacific Ocean. The majority of the world's earthquakes and volcanic eruptions occur as a result of the movement of these plates.
