The Mariana Trench is one of the least Visited places on Earth. Deep enough to swallow Mt. Everest, the Mariana Trench was first pinpointed in 1951 by the British Survey ship Challenger II. Known since as Challenger Deep, it was not visit for nearly ten years. The trench was first sounded during the Challenger expedition in 1875 using a weighted rope, which recorded depth of 4,475 fathoms ( 26,850 feet).
Geography Of Mariana Trench
The Mariana Trench in the Earth’s crust is more than 1,500 miles (2,550 kilometers) long and accordingly on the average, 43 miles . It is situated in the western Pacific, east of the Philippines and, on average, around 124 miles (200 kilometers) to the east of the Mariana Islands.
Nearly 7 miles separate the ocean’s surface from the Challenger Deep, the trench’s deepest point, which is located roughly 200 miles (322 kilometers) southwest of the U.S. island of Guam (11 kilometers). The peak of Mount Everest would still be submerge for more than a mile (1.6 kilometers) if it were lower into the Mariana Trench.
Formation Of Mariana Trench
Subduction is the mechanism that created the Mariana Trench. The crust of the Earth is compose of relatively thin plates that “float” top Of the planet’s mantle’s molten rock. These plates progressively clash with one another while floating on the mantle, and occasionally they even come together head-on.
Comparing Mariana Trench & Mount Everest
At 11,034 meters, it is more than seven miles deep (36,201 feet). Tell your children that if you placed the peak of Mount Everest at the deepest point of the Mariana Trench, it would still be 2,133 meters (7,000 feet) below sea level.
Facts About Mariana Trench
He continued that the western Pacific contains some of the world’s oldest seafloor, which is roughly 180 million years old, and that this is one reason the Mariana Trench is so deep. The Mariana Trench is named after the nearby Mariana Islands, which are named Las Marianas in honor of Spanish Queen Mariana of Austria, widow of Philip IV of Spain.
Temperature Of Mariana Trench
Water cools much more slowly below this threshold. The water temperature in the Mariana Trench both spellings are prevalent) ranges from 34 to 39 degrees F. (1-4 degrees C). The aphotic zone is follow by total darkness. No sunshine breaks through the blackness until you reach the sea floor, and also which is 1,000 meters below the surface.
The Mariana snailfish’s CT scan. In the snailfish’s gut, the green object is a tiny crustacean. University of Washington’s Unexpectedly many creatures exist in the trench likewise despite its hostile, acidic environment and lack of light. Crustaceans and amphipods are among the more than 200 identified microbes and small animals that call it home. It’s practically a given that more species will be found in the trench as further missions finally study it. In the trench, a novel species of snailfish was discovered.
Since no sunlight can penetrate the Mariana Trench likewise you may anticipate its waters to be quite cold. You’d be correct, too. There, the water typically has a temperature between 34 and 39 degrees Fahrenheit. What is startling, though, is how hot the water may also get. The trench is filled with hydrothermal vents.
At 700 F the water emerges from vents would be hot enough to scorch especially but don’t worry anyone not in a strong vessel would be crushed by the intense pressure first.
10 Strange Animals in the Mariana Trench
Dumbo Octopus
In comparison to other octopods, the dumbo octopus is small, with an average length of 20 to 30 centimeters. The Dumbo octopus was identified in 1883, the specimen was not observed until the 1990s, with the development of the deep-sea boats.
Angler Fish
The angler fish is known as marine creature. The females usually grow to around 8 inches long, and the males to only an inch in length. The males fuse themselves the females.
Frilled Shark
Species is more than 80 million years old. The shark has an body that’s dark brown to grey and Their teeth are widely spaced between 19 and 28 in the upper jaw and 21 to 29 in the lower.
Goblin Shark
Still unclear what the unusual snout is for. They can grow to be around 10-13 feet in length and are rarely seen by human beings.
Telescope Octopus
The telescope octopus is a eight-armed octopus and it is colorless. Their arms are the identical size, and they are the only octopus to have tubular eyes.
Zombie Worms
The Zombie worms, also known as Osedax, The word “Osedax” means “bone-eater” in Latin and refers to the worm’s ability to bore into and eat bones from whale carcasses.
Barreleye Fish
It is transparent skull to see predators above it. They are directed upwards in order to allow the fish to detect prey more easily.
Deep-sea Dragonfish
The Dragonfish, also known as the scaleless dragonfish, is a deep-sea predator with large teeth.
Sea Cucumber
Make up the vast majority of sea life on the deep-sea floor, and breathe through their anus. They are marina animals with leather-textured skin. Their bodies are long and found on the seafloor.
Snailfish
An incredibly deep-sea fish that is scaleless that would implode if goes to the surface. Snailfish is an unusual species that live in the Arctic Oceans.
