Top 10 Deepest Parts of the Oceans

deepest part of the oceansThe wonders of the world do not end in what is visible to us. There are also activities which takes place deep under the oceans and seas. There are many amazing facts which are hidden under the calm ocean. It won’t be wrong to say that even under the deep blue ocean there are certain places which are much deeper than the average depth of the oceans and seas. These zones are known as deep sea trenches and are characterized by complete darkness and unimaginable pressures. To know in detail about them, scroll further through the chart of top 10 deepest parts of the oceans.

Top Ten Deepest Parts of the Oceans

Are you really aware of the deepest parts of the oceans across the world? No? Then read through the given piece of article to know more about them.

1. Mariana Trench

Located in the Western Pacific Ocean at Challenger Deep, Mariana Trench or the Marianas Trench is the deepest parts of the oceans in the world. The trench is about 2,550 kilometers long and has an average width of 69 kilometers  At Challenger point it has a depth of 10.994 km. The Mariana Trench is part of the Izu-Bonin-Mariana Arc convergent boundary system that forms the boundary between two tectonic plates.

2. Tonga Trench

Second in the list of top 10 deepest parts of the oceans is Tonga Trench with a depth of 10,882 m below sea level. The Tonga Trench is a convergent plate boundary situated in the South Pacific Ocean. The Trench extends north-northeast from the Kermadec Islands north of the North Island of New Zealand. The trench turns west north of the Tonga Plate and becomes a transform fault zone. The edge of the trench is dotted with volcanoes and in 2007 it was reported that Massive underwater volcanoes were slipping into a highly active fault line in the Tonga Trench.

3. Kuril – Kamchatka Trench

The Kuril–Kamchatka Trench or Kuril Trench is an oceanic trench in the northwest of Pacific Ocean that lies off the southeast coast of Kamchatka and parallels the Kuril Island chain to meet the Japan Trench. It is about 2,000 km long, and its width ranges from 20 to 60 km which was formed due to the sub-duction zone. This narrow deep depression is also responsible for a number of ocean bed volcanic activities.

4. Philippine Trench

A submarine trench to the east of the Philippines, Philippine Trench’s deepest point has a depth of 34,600 feet. The trench was formed as a result of the collision between the Philippine Sea plate and the Eurasian plate. The submarine trench is located to the east of the Philippines.

5. Kermadec Trench

Formed by the subduction of the Pacific plate under the Indo-Australian Plate, Kermadec Trench is the fifth deepest part of the oceans with a depth of 10,047 m. The Trench is noted for its very abrupt slope and the volcanic islands around it are the only uninhabited islands in that hemisphere. In 2012, scientist discovered a super-giant- a type of amphipod in the Kermadec Trench.

6. Puerto Rico Trench

With a depth of 8,800 m and a length of over 800 kilometer, Puerto Rico Trench is in the sixth position in the list of top ten deepest parts of the oceans. It is located on the boundary between the Caribbean Sea and the Atlantic Ocean and according to scientific report an earthquake occurring along this fault zone could generate a significant Tsunami. The island of Puerto Rico lies next to the south of the fault zone and the trench.

7. South Sandwich Trench

South Sandwich Trench is 965 km long and has a maximum depth of 8,428 meters below sea level and is situated west of the Mid-Atlantic Ridge between South America and Antarctica. The South Sandwich Islands full of glaciers and volcanoes surround the trench. South Sandwich Trench is a tectonic plate under the Scotia Sea near Antarctica.

8. Romanche Trench

Also popular as the Romanche Furrow or Romanche Gap, Romanche Trench is known to have a depth of 7,760 m and runs 300 km long, close to the equator. Geologically, it is at the seam of the South American Plate to the west and the African Plate to the east. The trench is covered by debris of course, fragmented rocks resulting from gravitational sliding and slumping. The depth makes this place an ideal habitation for the deep water fish.

9. Java Trench

Java Trench is also called as Sunda Trench and is situated in the north-eastern Indian Ocean with a maximum depth of 7,725 m and a length of 2,600 km. It is a part of the Pacific ring of fire and a ring of oceanic trenches around the northern edges of the Australian Plate. The trench is divided into two parallel troughs by an underwater ridge and much of the trench is at least partially filled with sediments.

10. Eurasian Trench

This trench lies at a depth of 5,450 m and runs for about 350 kilometers under the frozen waters of Arctic Ocean. It is the deepest part of the Arctic Ocean and has the geographic North Pole located over its floor. The Eurasia Basin was formed by seafloor spreading along the axis of the Nansen-Gakkel Ridge.

    hey good research. but wonder why this topic? So dark….. could have been the beautiful oceans……..top ten…something like that.
