Answer:
The force that drives earthquake activity is plate tectonics.
Step-by-step explanation:
Plate tectonics is scientifically proven theory and explains the mechanism of earthquakes, volcanisms, formation of islands and so on. Earthquake is driven by the force due to the movement of plates. Earthquakes formed in all plate margins such as Constructive plate boundary, destructive plate boundary, and conservative plate boundary. Constructive plate boundary caused by the two forces acted in opposite direction, destructive plate boundary caused by the two forces acted in same direction.
