Explanation:

Subduction is the process where one tectonic plate (oceanic crust) sinks beneath another (continental crust). Seafloor spreading is about new oceanic crust formation. Erosion is about wearing - away of landforms. Convection currents are in the mantle and drive plate movement but not the specific sinking process described.

Answer:

Subduction
