Plate Tectonics - English Definition & Meaning

Definition

Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle. These plates are like giant puzzle pieces floating on a sea of hot rock. 🧩 The movement of these plates causes earthquakes, volcanoes, mountain building, and the formation of oceanic trenches. It's the engine that drives many of Earth's geological processes. Plate tectonics explains why continents drift and why certain areas are prone to seismic activity. Unlike basic tectonics, it specifies the mechanism as 'plates'.

Etymology

The term "plate tectonics" combines "plate" (referring to the lithospheric plates) and "tectonics" (from the Greek "tektonikos," meaning "pertaining to building"). It literally describes the "building" or arrangement of Earth's crust through the movement of plates.
