tectonic activity
Earth's plates shifting
Tectonic activity refers to the movements and interactions of large plates in Earth's crust—shifting, colliding, spreading apart, or sliding past one another.
These processes produce earthquakes, volcanic eruptions, and mountain formation.
The region's tectonic activity makes it prone to seismic events.
Figuratively, tectonic describes fundamental shifts: tectonic changes in the industry.
