which process describes one tectonic plate moving beneath another plate?\n\nsubduction\nweathering\nsmelting\…

Brief Explanations:

Subduction is a geological process that occurs at convergent boundaries where two tectonic plates collide. During this process, the denser plate (usually oceanic lithosphere) is forced downward into the Earth's mantle beneath a less dense plate (either continental or younger oceanic lithosphere). This process is responsible for the formation of deep-ocean trenches, volcanic arcs, and seismic activity. The other options provided—weathering, smelting, and soil creep—refer to surface rock breakdown, metal extraction, and slow downslope soil movement, respectively.

Answer:

Subduction
