Here's why:

* Subduction is the process where one tectonic plate moves underneath another.

* Zone implies a region or area.

So, a subduction zone is the region where one tectonic plate is being forced beneath another. This process often leads to:

* Volcanoes: As the descending plate melts, magma rises to the surface, forming volcanoes.

* Earthquakes: The movement and friction between the plates create earthquakes.

* Mountain Ranges: Subduction zones can contribute to the formation of mountain ranges.
