Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the term for the process by which a heavier, denser plate slides under a less dense plate?
A
plate boundary
B
submersion
C
accretion
D
subduction
Explanation: 

Detailed explanation-1: -Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate, the heavier plate dives beneath the second plate and sinks into the mantle. A region where this process occurs is known as a subduction zone, and its surface expression is known as an arc-trench complex.

Detailed explanation-2: -This process, called “subduction, ” involves an older, denser tectonic plate being forced deep into the planet underneath a younger, less-dense tectonic plate. When this process occurs in the ocean, an trench">ocean trench can form.

Detailed explanation-3: -When these collisions occur, the more dense plate slides below the other, which is a process called subduction. So for oceanic-oceanic boundaries, the more dense oceanic plate sinks below the less dense oceanic plate.

Detailed explanation-4: -The denser plate sinks below the more buoyant plate in a process called subduction. The area where a denser plate descends into Earth along a convergent plate boundary is called a subduction zone.

Detailed explanation-5: -Subduction occurs when an oceanic plate runs into a continental plate and slides beneath it.
