* Subduction Zones: This is the area where one tectonic plate (usually an oceanic plate) slides beneath another (either oceanic or continental). This process is driven by the movement of the Earth's mantle and results in:

* Volcanoes: Melting of the descending plate creates magma that rises to the surface.

* Earthquakes: Friction along the subduction zone releases energy in the form of earthquakes.

* Trenches: The downward bending of the subducting plate forms deep trenches in the ocean floor.

Let's look at the other options:

* Rift Valley: A rift valley forms when tectonic plates move apart (diverge), causing the Earth's crust to stretch and break.

* Ocean Basin: Ocean basins are large depressions on the Earth's surface filled with water. They form over long periods of time due to plate tectonics and the movement of continents.

* Ridge: A ridge is an underwater mountain range formed by the spreading of tectonic plates (divergence) at mid-ocean ridges.

In summary: The process of one oceanic plate being forced beneath another is specifically called subduction.
