What type of boundary is the Mariana Trench on?

What type of boundary is the Mariana Trench on?

convergent boundary
In the case of a convergent boundary between two oceanic plates, one is usually subducted under the other, and in the process a trench is formed. “The Marianas Trench (paralleling the Mariana Islands), for example, marks where the fast-moving Pacific Plate converges against the slower moving Philippine Plate.

What type of trench is the Mariana Trench?

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.

How Marianas Trench was formed?

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.

Is the Mariana Trench a fault line?

Mariana outer rise bathymetry exhibits distinct faults, located closer than 100 km distance from the trench, with an onset at approximately the 6000 m bathymetric depth contour [Oakley et al., 2008; Gardner, 2010].

What type of boundary is made by the Mariana Trench transformation reformation?

Answer: The boundary between the Mariana and the Pacific Plate to the east is a subduction zone with the Pacific Plate subducting beneath the Mariana. This eastern subduction is divided into the Mariana Trench, which forms the southeastern boundary, and the Izu-Ogasawara Trench the northeastern boundary.

Is the Mariana Trench geologically active?

The active volcanoes of the Mariana Arc are mostly seamounts (underwater volcanoes), with summits that are only a few hundred meters (< 1,000 feet) below the ocean’s surface, and only nine are tall enough to form islands. Many are spaced out along a chain with the largest volcano situated farthest east.

Where is Mariana Trench?

the Pacific Ocean
The Mariana Trench in the Pacific Ocean is so deep your bones would literally dissolve. What’s down there in its black, crushing depths? Somewhere between Hawaii and the Philippines near the small island of Guam, far below the surface of the water, sits the Mariana Trench, the deepest spot in the ocean.

Is the Mariana Trench a divergent boundary?

The Mariana Plate is a micro tectonic plate located west of the Mariana Trench which forms the basement of the Mariana Islands which form part of the Izu–Bonin–Mariana Arc. It is separated from the Philippine Sea Plate to the west by a divergent boundary with numerous transform fault offsets.

What plate boundary creates a trench?

subduction
In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plates meet. At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench.

What is divergent and convergent boundaries?

Divergent boundaries — where new crust is generated as the plates pull away from each other. Convergent boundaries — where crust is destroyed as one plate dives under another.
