Question 26: Geography

In which one of the following oceans is Diamantina Trench situated?

aPacific Ocean
bAtlantic Ocean
cIndian Ocean
dArctic Ocean

AnswerThe answer is (c).

The Diamantina Trench (also called the Diamantina Fracture Zone) lies in the south-eastern Indian Ocean, to the south-west of Australia. It is an Indian Ocean feature, and should not be confused with the better-known Pacific trenches such as the Mariana, Tonga and Kermadec, or with the Puerto Rico Trench in the Atlantic. For ocean-feature questions, learn the ocean for each famous trench and deep.

Why each option is right or wrong
  • (a) The Mariana, Tonga and Kermadec trenches are in the Pacific; Diamantina is not.
  • (b) The Puerto Rico Trench is the Atlantic's deep; Diamantina is elsewhere.
  • (c) Correct: the Diamantina Trench is in the south-eastern Indian Ocean.
  • (d) The Arctic Ocean has no major trench like this.
