Question

Explain what happens in a subduction zone.

Answer 1

Answer:

Subduction zones circle the Pacific Ocean, forming the Ring of Fire. A subduction zone is the biggest crash scene on Earth. These boundaries mark the collision between two of the planet's tectonic plates. ... At a subduction zone, the oceanic crust usually sinks into the mantle beneath lighter continental crust. Subduction zones are plate tectonic boundaries where two plates converge, and one plate is thrust beneath the other. This process results in geohazards, such as earthquakes and volcanoes.Volcanoes, earthquakes, tsunamis, mountain ranges, mid ocean ridges, rifts, trenches, and island arcs would cease to exist. There would be no magma from oceanic-continental subduction zones to form volcanoes, and most already existing features would be eroded away.There are three types of plate boundaries: convergent, divergent and transform. Convergent boundaries are where two plates are moving towards each other, and this is where subduction zones can be created. A subduction zone is where two plates collide and become sandwiched on top of each other. Subduction zone is a place where the Earth's crust is broken down and consumes part of the oceanic crust or oceanic plate, which underscores (subduction) under a continent or island arc.

Answer 2

Answer:

A subduction region is shaped at a convergent plate boundary whilst one or each of the tectonic plates consists of oceanic crust. The denser plate, fabricated from oceanic crust, is subducted beneath the much less dense plate, which may be both continental or oceanic crust.

• Tectonic plates are portions of the Earth’s inflexible outer layer that slowly circulate throughout the planet's floor over tens of thousands and thousands of years, in keeping with NOAA.

• This is the primary guideline of plate tectonics, the principle that quantities of Earth's shell waft over the decreased mantle, taking continents with them.
• That outer layer, called the lithosphere, includes the Earth’s crust and the higher phase of the mantle, a dense, warm layer under the crust, in keeping with the U.S. Geological Survey(USGS).
• When two tectonic plates meet at a subduction sector and one slides below the other, this lithosphere cloth curves down into the recent mantle.

• This subduction system often takes place due to the 2 one-of-a-kind forms of lithosphere that make up tectonic plates: Continental and oceanic.
• Because the oceanic cloth is denser than the continental lithosphere, while the 2 collide at a subduction sector, the oceanic component sinks into the mantle under the extra buoyant continental lithosphere, in keeping with NOAA.
