- Important information regarding the Pacific Ring of Fire
- The Circum-Pacific Belt, often known as the Ring of Fire, is a line along the Pacific Ocean characterized by active volcanoes and frequent earthquakes.
- It follows the tectonic plate boundaries of the Pacific, Juan de Fuca, Cocos, Indian-Australian, Nazca, North American, and Philippine Plates.
Q. The Ring of Fire, a horseshoe-shaped zone encircling the Pacific Ocean, is known for its intense geological activity, including earthquakes and volcanic eruptions. Discuss the geological processes that led to the formation of the Ring of Fire and the implications of this region's dynamic nature on the countries it encompasses.
