What is the general relationship between global earthquake activity and plate boundaries?

The correct answer is that "Earth is considered to be an active planet. Its surface consists of many individual plates that passes and engaging one another, constantly changing and reshaping Earth's outer layer. Volcanoes and earthquakes each end result from the motion of tectonic plates."

The given answer was based on the plate tectonics theory, wherein Earth is composed of many individual plates that interact , which shapes and changes the Earth's Outer Layer.
