subducted
Slid beneath another
Subducted is the past tense of subduct, a geological term for when one tectonic plate slides beneath another at a convergent boundary.
The subducted plate descends into the Earth's mantle: The oceanic crust subducted beneath the continental plate over millions of years.
The process, subduction, creates deep ocean trenches and volcanic activity.
