PDE Q25

0. Where are most of the earth's active volcanoes concentrated?

  • Option : B
  • Explanation :

    Most of the Earth's active volcanoes are concentrated around the Pacific Ocean, in a region famously known as the "Ring of Fire."

    • This is a horseshoe-shaped zone that follows the edges of the Pacific tectonic plate.

    • It contains about 75% of the world’s active and dormant volcanoes.

    • It is also a zone of frequent earthquakes and tectonic activity.

    • Option A: Europe – Has a few volcanoes (e.g., Mount Etna, Vesuvius), but not the largest concentration.

    • Option B: Pacific Ocean – Correct. The “Ring of Fire” surrounds this ocean and holds the majority of active volcanoes.

    • Option C: Africa – Home to some volcanoes (e.g., Mount Kilimanjaro, Nyiragongo), but fewer in number.

    • Option D: South America – Has volcanoes in the Andes (e.g., Cotopaxi, Ojos del Salado), part of the Ring of Fire, but not the majority concentration.
