tectonic movement
Earth's plates drifting
Tectonic movement is the large-scale motion of plates in Earth's crust—the slow shifting, colliding, and separating that builds mountains, opens oceans, and triggers earthquakes.
The term extends to any massive structural shift: tectonic movements in global politics, tectonic changes in the industry.
The metaphor emphasizes fundamental, ground-level transformation rather than surface adjustments.
