Answer : Option B
Explanation :
The movement of these tectonic plates is likely caused by convection currents in the molten rock in Earth's mantle below the crust. Earthquakes are the short-term results of this tectonic movement. The long-term result of plate tectonics is the movement of entire continents over millions of years.
