Older, colder, more dense oceanic crust is being subducted into the mantle.
In areas where a trench is formed, the ground is dug out to create a deep, narrow channel. Trenches are commonly used in construction, agriculture, and military applications for purposes such as laying pipes, irrigation, or providing defensive barriers. They can also be a habitat for some wildlife species.
The Kermadec Trench is an oceanic trench that has a depth of 32,963 feet. This trench region is located between the North Island of New Zealand and an island called Tonga.
The Mariana Trench is a convergent plate boundary.
The Marianas (or Mariana) Trench is formed by the subduction of the Pacific Plate as it is forced under the smaller Mariana Plate at the bottom of the ocean between Japan and New Guinea.
The South Sandwich Trench was formed by the process of subduction, where one tectonic plate is forced under another. In this case, the South American Plate is subducting beneath the South Sandwich Plate, creating a deep trench in the ocean floor. Subduction zones like the South Sandwich Trench are common around the Pacific Ring of Fire, where many of the Earth's earthquakes and volcanic activity occur.
Subduction
Trench
A trench happens when one plate submerges under another.
When an oceanic to oceanic happens, two oceanic plates converge and one of the plates subducts into a trench. The subducted plate sinks down into the mantle and begins to melt. Molten rock from the plate rises toward the surface and forms a chain of volcanic islands, also called a volcanic island arc, behind the trench in the ocean.
A trench stretch is a long system of trench.
