Which explains earthquakes and volcanic eruptions?

global positioning theory
lithospheric theory
plate tectonics theory
nebular theory

C. Plate tectonics theory

Explanation:

According to the plate tectonics theory outer layer of earth is divided into seven major and some minor plates. And these plates form convergent,divergent and transverse boundaries. So the Pacific ring of fire, subduction zone, continental drift are evidences of plate tectonics theory. Earthquakes and volcanic eruption are also explained by plate tectonics theory.
