Question

The deepest point of the ocean is _____ in the Pacific Ocean near Philippine islands.
A. Tonga trench
B. Kuril trench
C. Challenger deep
D. None of these

Answer 1

Hint: The Pacific Ocean is the deepest and the largest Oceans on Earth. It has a surface area of 165,250,000 sq. km and an average depth of 4,280 m and a maximum depth of 10,911 m. It is larger than all of the Earth’s land area combined.

Complete answer: - Option A: Tonga Trench is located in the south-west Pacific Ocean and is the second deepest trench on Earth and the deepest trench of the Southern Hemisphere. The Horizon Deep is the deepest point of the Tonga Trench. Hence, this is an incorrect option.
- Option B: Kuril Trench is a trench in the northwest Pacific Ocean. It is near Russian mainland and parallels the Kuril island chains. Hence, this is an incorrect option.
- Option C: Challenger Deep is a part of the Mariana Trench which is located in the western Pacific Ocean 200 km east of the Mariana Islands. It is the deepest oceanic trench on Earth. Challenger Deep is the deepest point of the Mariana Trench making it the deepest known point on the Earth’s seabed. It is at a depth of 10,911 m. If Mount Everest is placed in the trench the peak would still be underwater by more than two km. Only 13 people have reached the Challenger Deep. Hence, this is the correct option.

Hence, The correct answer is Option C.

Note: The deepest trench in the world is Mariana Trench and it is located in the western Pacific Ocean, 200 km east of the Mariana Islands. The deepest point of the ocean is also located in this trench.
