The oceans continue to hold secrets from the human race. The ocean trenches are huge underwater depressions. These cavities can measure more than 11 kilometers below sea level and in the world there are only a few distributed, mainly, by the Pacific Ocean.Normally, these oceanic trenches are usually found next to continental edges or next to arches of volcanic islands. The temperature in these cavities is usually between 2 and 0 degrees Celsius and, although it seems incredible, marine life also has a place in the most unknown depths of the ocean.In the Pacific Ocean there are six of the deepest on Earth, which they exceed 10 kilometers deep. Mariana Trench It is the deepest marine trench known on the planet. According to the experts who have been able to study this place, its maximum depth would be located at 11,000 meters, a place known as the Challenger Abyss. The length of the pit is estimated to be 2,550 kilometers, with a width of 69 kilometers. The pressure, as it occurs in sea trenches, is much lower in the depth of the ocean, being in the Marianas up to almost 1,000 times greater than at sea level. Tonga Trench It is the second deepest known trench. in the planet. Its location is at the point where the Pacific enters under the Tonga plate and the Indo-Australian plate. This trench has a maximum depth of 10,882 meters and is known as the ‘Deep Horizon’. Its situation has made this area one of the most active in the world with regard to earthworks.The tectonic movement advances at 24 centimeters per year, which is why many earthquakes occur in this place that can become tsunamis.Philippines Trench Discovered by German scientists in 1927, it is the third deepest trench on the planet reaching 10,540 meters deep and It is known as Galathea. It borders the coast of the islands of Mindanao, Simar and other adjacent islands that are concentrated in this area. According to experts, its length is 1,320 kilometers and it is about 30 kilometers wide. On a recent trip to this pit, researchers Deo Florence Onda and Víctor Vescovo discovered something that struck them at their deepest point. When they went to look for unknown marine animals, they came across something unexpected: a grave full of garbage.
