Question

The Ring of Fire is found along the margins of the _____.
a)Pacific ocean
b)Atlantic ocean
c)Indian ocean
d)Mediterrenean ocean

Answer 1

Hint: Ring of Fire is a seismically active belt of earthquake epicentres, volcanoes and tectonic boundaries. It is a horseshoe shaped belt that follows the chains of island arcs such as Tonga and New Hebrides, the Indonesian archipelago, the Philippines, Japan, the Kuril Islands, and the Aleutians, as well as other arc-shaped geomorphic features, such as the western coast of North America and the Andes Mountains.

Complete answer: The Ring of fire is 40,000km in length and surrounds the boundaries of several tectonic plates including the Pacific, Juan de Fuca,Cocos,Indian-Australian, Nazca, North American, and Philippine Plates.
Let us look at the options given to us :
Option A- Pacific ocean is the correct answer as the Ring of Fire is also called the Circum Pacific belt. This belt goes around the Pacific basin. It is marked by volcanoes and earthquakes as most areas covered by the belt have convergent boundaries forming subduction zones. 75 percent of the world’s volcanoes occur within the Ring of Fire.
Option B- Atlantic ocean is the second largest ocean in the world. It has a S shaped basin with Europe and Africa on one side and North and South America on the other. The Ocean has the Mid Atlantic ridge which separates the North American plate from the Eurasian and the African plate. It is the longest mountain range in the world.
Option C- Indian ocean is the third largest ocean in the world and is surrounded by Asia to the North, Africa to the west , Australia to the East and Antarctica in the south. The Indian ocean has one of the largest volcanic plateaus in the world-the Kerguelean plateau.
Option D- Mediterrenean sea is a sea sandwiched between Southern Europe and Northern Africa and is linked to the Atlantic ocean. This sea also has some underwater volcanoes like the Marsili volcano of the Aeolian island volcanic arc.

Therefore the correct answer is option (A).

Note: Some major volcanoes on the Ring of Fire include Mount Tambora, Krakatoa, Novarupta, Mount Saint Helens, Mount Ruiz, and Mount Pinatubo. Devastating earthquakes like the Chile earthquake of 1960, Alaska earthquake of 1964 and Japan earthquake of 2011 happened around the Ring of Fire.
