What geological event results from sudden movement of tectonic plates?

• A. Tsunamis
• B. Volcanoes
• C. Earthquakes
• D. Hurricanes

Answer: (C)

Movement of tectonic plates stores energy in rocks until they fracture and slip suddenly along faults. That abrupt rupture releases energy as seismic waves, shaking the ground and producing what we call an earthquake. This is the best choice because it directly describes the instantaneous energy release tied to plate motion. Tsunamis can be triggered by undersea earthquakes, but the initiating event is the earthquake itself. Volcanoes come from magma movement and pressure changes within the crust and mantle, not simply plate motion, and hurricanes are atmospheric storms, not geological processes.
