उत्तर
The Pacific Ring of Fire is a horseshoe-shaped zone surrounding the Pacific Ocean’s margins where there are frequent earthquakes and volcanic eruptions. It is known as the “Ring of Fire” because the region is home to numerous active volcanoes that frequently erupt, spilling lava, gases, and ash, giving the impression that the area is surrounded by fire.
