摘要

Subduction zones, where Earth's lithospheric plates return to the deep mantle, are responsible for spectacular explosive volcanic eruptions, the planet's greatest earthquakes, and some of our most valuable concentrations of economic ores. Subduction's delivery of surficial materials to the mantle means that it plays a primary role in terrestrial element cycling. On a larger scale, subduction helps drive plate tectonics, as plate movement is chiefly driven by the downward pull of oceanic slabs sinking into the mantle.
