Mariana trench

Mariana trench

It is crescent-shaped and measures about 5km (5mi) in length and km (mi) in width. Mariana Trench , also called Marianas Trench , deep-sea trench in the floor of the western North Pacific Ocean, the deepest such trench known on Earth, located mostly east as well as south of the Mariana Islands. Explore the Mariana Trench. Because of its extreme depth, the Mariana Trench is cloaked in perpetual darkness and the temperature is just a few degrees above freezing.


The water pressure at the bottom of the trench is a crushing eight tons per square inch—or about a thousand times the standard atmospheric pressure at sea level. Pressure increases with depth. Located in the Pacific Ocean, the Mariana Trench forms a large crescent-shaped depression in the sea bed in the vicinity of the Mariana Islands, after which the trench is named. Within the Mariana Trench is Challenger Deep, the world’s deepest point.


The Challenger Deep, in the southern end of the Mariana Trench (sometimes called the Marianas Trench ), is the deepest spot in the ocean.

In this system, the western edge of one plate, the Pacific Plate, is subducted (i.e., thrust) beneath the smaller Mariana Plate that lies to the west. of 6Records recording artists Marianas Trench.


Total length of the Mariana Trench is 5miles while its average width is miles. Mariana Trench is the deepest place in the world and it lies to the east of Mariana islands, in the western Pacific Ocean. Facts about Mariana Trench 8: a map about Mariana Trench.


It English, it means Deep map of the Great Ocean. The location of the sounding was called a Challenger Tief. The deepest part of the ocean is called the abyssal zone.

Angler Fish (see illustration), so called because it uses a bioluminescent (life light) protrusion to attract its prey. Learn more about the weird creatures from the Marinana Trench at HowStuffWorks. The MRis full-ocean-depth capable, and provides both bathymetry and sidescan data. The Mariana Trench is 5km (5miles) long and km (miles) wide. Since the trench is so far away from any rivers, it does not get filled with sediment like many other oceanic trenches.


This also contributes to its extreme depth. It also contains the deepest known point in any ocean. Due to the sheer extent of the Mariana Trench , no single photograph displays it in its entirety.

Here we present a sonar generated compilation image. It is also the deepest known location on Earth itself. It lies south and east of the Mariana Islands, and has a depth up to 19m. The western end of the trench is near Guam.


The trench is about 5kilometres (5miles) long but has a mean width of only kilometres (miles). Then they also have to deal with the pressure and the col which in effect “sets” the fat that forms the membranes of the body’s cells. Feeding at the Bottom of the Mariana Trench.


The absence of sunlight in the deepest reaches of the Mariana Trench means that there are no plants or algae to support the food chain. Deep-sea organisms have to rely on decaying matter from dead creatures from the upper regions of the ocean. In addition to exploring the Mariana Trench , the Challenger gathered important data on the features and species of the Pacific, Atlantic, and Indian oceans, covering nearly 130kilometers, (approx.


70nautical miles). Students locate the Mariana Trench on a map, discuss who has jurisdiction over it, and identify the challenges of exploring the deepest place on Earth. Rather, the abyss marks the location of a subduction zone.


Subduction zones occur where one part of the seabed—in this case the Pacific plate—dives beneath another, the Philippine plate.
