Question

What is the name of the oceanic trench in the Indian Ocean with a maximum depth of 23,560 feet?

A.

Tonga Trench

B.

Amirante Trench

C.

Java Trench

D.

Diamantina Trench

Correct option is C

The correct answer is (c) Java Trench.

The Java Trench (also known as the Sunda Trench) is the oceanic trench located in the Indian Ocean and has a maximum depth of around 23,560 feet (7,258 meters). It lies off the southern coast of the islands of Java and Sumatra in Indonesia and is the deepest point in the Indian Ocean.

  • The trench is the result of the subduction of the Indo-Australian Plate beneath the Eurasian Plate, leading to high seismic and volcanic activity in the region.
  • It is also closely associated with the Ring of Fire, an area known for frequent earthquakes and volcanic eruptions.

Information Booster:

  • Java Trench: Stretches approximately 2,600 kilometers, and is one of the most prominent features of the Indian Ocean floor.
  • Oceanic Trenches: These are long, narrow depressions on the ocean floor, typically formed by the process of subduction, where one tectonic plate moves beneath another.
  • Amirante Trench: Located in the Indian Ocean near the Seychelles but not as deep as the Java Trench.
  • Tonga Trench: Found in the South Pacific Ocean, with depths exceeding the Java Trench, but it is not located in the Indian Ocean.
  • Diamantina Trench: Also located in the Indian Ocean, near the southwest coast of Australia, but it is not as deep as the Java Trench.
