THE HADAL ZONE IN THE TRENCHES

The Trenches

    The Trenches are the home to many strange creatures.  None of these creatures are very big.  Most of them have no coloration or eyes.  Most of the creatures are bacteria. The trenches are the deepest part of the ocean. They are also very long. Some trenches are located in Japan and The Phillipenes. The deepest trench in the world is the Mariana trench. Most trenches are found between continental crust and oceanic crust. Some trenches are created as a result of erosion by rivers. On average, a trench is 2.5 miles below the ocean floor. Only bacteria and microscopic organisms live in these trenches.

Hadalpelagic Zone - Beyond the abyssopelagic zone lies the forbidding hadalpelagic zone. This layer extends from 6000 meters (19,686 feet) to the bottom of the deepest parts of the ocean. These areas are mostly found in deep water trenches and canyons. The deepest point in the ocean is located in the Mariana Trench off the coast of Japan at 35,797 feet (10,911 meters). The temperature of the water is just above freezing, and the pressure is an incredible eight tons per square inch. That is approximately the weight of 48 Boeing 747 jets. In spite of the pressure and temperature, life can still be found here. Invertebrates such as starfish and tube worms can thrive at these depths.
