What features does the Mariana Trench have?
The region surrounding the trench is noteworthy for many unique environments. The Mariana Trench contains the deepest known points on Earth, vents bubbling up liquid sulfur and carbon dioxide, active mud volcanoes and marine life adapted to pressures 1,000 times that at sea level.
What is the Mariana Trench kids?
The Mariana, or Marianas, Trench is a deep-sea trench in the floor of the western North Pacific Ocean. It is located about 124 miles (200 kilometers) east of the Mariana Islands. It is the deepest such trench known on Earth and thus the deepest known point in the ocean.
Why Mariana Trench is so deep?
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. When it’s fresh, lava is comparatively warm and buoyant, riding high on the underlying mantle.
Is Mariana Trench the deepest?
The Mariana Trench, in the Pacific Ocean, is the deepest location on Earth. According to the Exclusive Economic Zone (EEZ), the United States has jurisdiction over the trench and its resources. Scientists use a variety of technologies to overcome the challenges of deep-sea exploration and explore the Trench.
What is the Mariana Trench made of?
The Mariana Trench was formed through a process called subduction. Earth’s crust is made up of comparably thin plates that “float” on the molten rock of the planet’s mantle. While floating on the mantle, the edges of these plates slowly bump into each other and sometimes even collide head-on.
Why is the Mariana Trench so dark?
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.
How old is the Mariana Trench?
about 180 million years old
“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.
How was the Mariana Trench made?
The Mariana Trench, in the South Pacific Ocean, is formed as the mighty Pacific plate subducts beneath the smaller, less-dense Philippine plate. In a subduction zone, some of the molten material—the former seafloor—can rise through volcanoes located near the trench.
Who owns Mariana Trench?

What is the deepest part of the Mariana Trench?
Victor Vescovo, a retired naval officer, made the unsettling discovery as he descended nearly 35,853ft (10,927 meters) to a point in the Pacific Ocean’s Mariana Trench that is the deepest place on Earth, his expedition said in a statement on Monday. His dive went 52ft (16 meters) lower than the previous deepest descent in the trench in 1960.
