Where are deep ocean trenches found?

Trenches are found on the floor of the sea; however, their common name is deep ocean trenches because they are more often found in the deepest areas of the ocean. Trenches are formed in subduction zones where tectonic plates collide. There are many known trenches that scientists continue to study.

Where are deep ocean trenches located mostly?

Deep-sea trenches generally lie seaward of and parallel to adjacent island arcs or mountain ranges of the continental margins. They are closely associated with and found in subduction zones—that is, locations where a lithospheric plate bearing oceanic crust slides down into the upper mantle under the force of gravity.

Where are deep ocean trenches found quizlet?

What are deep-ocean trenches? Long, narrow creases in the seafloor representing the deepest parts of the ocean floor. Most are located along the margins of the Pacific Ocean, with only two being located in the Atlantic.

Why are trenches the deepest part of the ocean?

“In order for this to sink back into the earth, it has to bend downward, and these are very gentle bends.” One reason the Mariana Trench is so deep, he added, is because the western Pacific is home to some of the oldest seafloor in the world—about 180 million years old. Seafloor is formed as lava at mid-ocean ridges.

What was found in the Mariana Trench?

The organisms discovered in the Mariana Trench include bacteria, crustaceans, sea cucumbers, octopuses and fishes. In 2014, the deepest living fish, at the depth of 8000 meters, Mariana snailfish was discovered near Guam.

Is Megalodon in the Mariana Trench?

Quote from video:Trench reports of megalodon sightings can be found on many different websites. Science tells us that megalodon sharks are extinct.

Is there a monster in the Mariana Trench?

Recent expeditions have found myriad creatures living out their lives at the bottom of the sea-floor. Xenophyophores, amphipods, and holothurians (not the names of alien species, I promise) all call the trench home.

What sharks live in the Mariana Trench?

Goblin sharks are considered to be living fossils, meaning they’ve roamed deep ocean trenches like the Mariana for millions of years unchanged from an evolutionary standpoint.

Is the megalodon still alive?

Megalodon is NOT alive today, it went extinct around 3.5 million years ago. Go to the Megalodon Shark Page to learn the real facts about the largest shark to ever live, including the actual research about it’s extinction.

Have we explored the bottom of the Mariana Trench?

It sits 36,070 feet below sea level, making it the point most distant from the water’s surface and the deepest part of the Trench. While the number of people that have climbed to the top of Mount Everest, the Earth’s highest point, holds somewhere in the thousands, only 3 divers have ever explored the Challenger Deep.

What lives in the bottom of the Mariana Trench?

The organisms discovered in the Mariana Trench include bacteria, crustaceans, sea cucumbers, octopuses and fishes. In 2014, the deepest living fish, at the depth of 8000 meters, Mariana snailfish was discovered near Guam.

How deep can humans go in the ocean?

How deep in the ocean can the human body go? That means that most people can dive up to a maximum of 60 feet safely. For most swimmers, a depth of 20 feet (6.09 metres) is the most they will free dive. Experienced divers can safely dive to a depth of 40 feet (12.19 metres) when exploring underwater reefs.

What did Victor Vescovo find in the Mariana Trench?

More disturbingly, at the bottom of the Pacific Ocean’s Mariana Trench, Vescovo spotted what he said was a plastic bag and candy wrappers, proving even the deepest depths of the world’s ocean aren’t exempt from manmade interference.

What did James Cameron discover?

Editor’s note: On March 26, 2012, James Cameron made a record-breaking solo dive to the Earth’s deepest point, successfully piloting the DEEPSEA CHALLENGER nearly 7 seven miles (11 kilometers) to the Challenger Deep in the Mariana Trench.

Can you dive the Mariana Trench?

Quote from video:You would never make it to the bottom of the ocean without any equipment. Because you would run out of oxygen. And your body would be shut down by the pressure underwater.

Is there anything deeper than the Mariana Trench?

The deepest place in the Atlantic is in the Puerto Rico Trench, a place called Brownson Deep at 8,378m. The expedition also confirmed the second deepest location in the Pacific, behind the Challenger Deep in the Mariana Trench. This runner-up is the Horizon Deep in the Tonga Trench with a depth of 10,816m.

What’s the deepest place on Earth?

The Mariana Trench

The Mariana Trench, in the Pacific Ocean, is the deepest location on Earth.

What if we drained the Mariana Trench?

Quote from video:Well Vargas said you know I don't know if I said your name right but you said if you drained it you would most likely find a Megalodon.

What surprise did they find at the bottom of the trench?

Unwelcome find: While Vescovo potentially discovered four new species, he also found a plastic bag and candy wrappers. It’s not the first time plastic has been found at the bottom of the sea, but it’s a reminder of the scale of the problem.

Did James Cameron get to the bottom of the ocean?

On , film-maker and explorer James Cameron made a record-breaking solo dive 10,908 metres (35,787 feet) below the surface of the Pacific Ocean in the DEEPSEA CHALLENGER submersible vessel to reach the world’s deepest frontier.

Have we found the deepest part of the ocean?

The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 10,935 meters (35,876 feet) deep.

How long to get to the bottom of the Mariana Trench?

Pre-expedition estimates put the Challenger Deep descent at about 90 minutes. (Animation: Cameron’s Mariana Trench dive compressed into one minute.) By contrast, some current remotely operated vehicles, or ROVs, descend at about 40 meters (130 feet) a minute, added Stern, who isn’t part of the expedition.

What country is closest to the Mariana Trench?

Guam is the closest land mass to the Mariana Trench, which dips down about 6.8 miles (11 kilometers) below sea level — the deepest point on the planet’s surface.

Who discovered the Mariana Trench?

Everest, the Mariana Trench was first pinpointed in 1951 by the British Survey ship Challenger II. Known since as Challenger Deep, it was not visited for nearly ten years. Jacques Piccard and Don Walsh descended in a submersible called the Trieste, which could withstand over 16,000 pounds of pressure per square inch.
