Q1. In which one of the following oceans Diamantina Trench is situated?
Explanation
The Diamantina Trench is a deep-sea trench located in the southeastern Indian Ocean, off the coast of Western Australia. It is part of the Diamantina Fracture Zone, a complex series of deep troughs and ridges. The trench was formed due to seafloor spreading and tectonic activity in the Indian Ocean basin. It is not associated with a subduction zone, unlike many other deep-sea trenches such as the Mariana Trench in the Pacific Ocean.
