The deepest point of the Indian Ocean is located in Sunda Trench some time known as Java Trench. The maximum depth in the Sunda Trench is 7450 meters deep. This trench is also part of the Pacific Ring of Fire and one of the rings of oceanic trenches. This is the reason that some of the most active volcanoes are present here. The 2004 earthquake of Sumatra, Java, and Andaman Nicobar Islands are some of the examples which prove the same.

Warmest Ocean in the world

The Indian ocean has its climatic zone. Because its northern zone is surrounded by Asian countries so the average temperature remains 24 degrees Celsius and the warmest one is 28 degrees Celsius because of the presence of Equator.

Marine life is struggling here

Due to the monsoon winds, the Indian Ocean hosts the world’s largest concentration of the phytoplankton. Increasing global warming and water pollution caused a large reduction of fishes and marine products in the Indian Ocean area. Although its 80% area is open, somehow animals like Dugong, Green sea Turtle, Fin whale, Indo- Pacific humpback, and many more are considered as the endangered species. Because of the low oxygen level and high temperature, the Indian Ocean has limited sea life.

It has the largest mangrove in the world

Nearly half of the total Mangrove area is located along with the Indian Ocean coasts. The area covers 80984 square kilometers. Among this area, the largest one comes under Indonesia with 42500 square kilometers.

Receives the highest volume of drainage water

It receives 6000 kilometers of river runoff, especially from the Ganges- Brahmaputra, Indus, Jubba river.

Numerous Marginal seas, coasts, shelves, rivers, and sea basins located along with the Indian Ocean region. Among them Bay of Bengal, the Arabian Sea, Andaman sea, Great Australian Bight, Red Sea.

One of the highest numbers of oil production happens

The Indian Ocean contributes worlds 40% of the total oil production. India, Arabian countries are involved in this production on a large scale.

There is a submerged continent

Around 130 billion years ago a microcontinent named Kerguelen Plateau has broken away from Gondwana Land(a supercontinent). Located in the southern part of the Indian Ocean, Kerguelen Plateau is 3000 kilometers southeast of Australia and larger than Japan. From north to west and east to south the plateau covers 220 kilometers and the whole part of that plateau lies under the water.

The Ocean is divided by a mid-ocean ridge

5000 kilometers long the Ninety East Ridge divides the Indian Ocean into East and West.

It is located in the southward of Bay of Bengal towards somewhere near another mid-ocean ridge called South East Asian Ridge.

Connects three different plates

In the southern Indian Ocean bed, there is a point that connects three tectonic plates – African plate, Indo Australian Plate, and the Antarctic Plate. This R-R-R type junction point is known as Rodrigues triple junction Point additionally called Central Indian Triple Junction.
