Key points about Pacific Ring of Fire

• It also known as the Circum-Pacific Beltis a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes.
• Its length is approximately 40,000 kilometres.
• It traces boundaries between several tectonic plates—including the Pacific, Juan de Fuca, Cocos, Indian-Australian, Nazca, North American, and Philippine Plates.

Q1) What is the subduction zone?

A subduction zone is a geological boundary where two tectonic plates converge, and one plate is forced beneath the other into the Earth’s mantle. Subduction zones are some of the most geologically active and dynamic regions on the planet and are associated with various geological phenomena, including earthquakes, volcanic activity.
