Question

According to the theory plate tectonics, the Earth's crust is broken into about 12 plates that float on hotter, softer rocks in the underlying mantle. These plates move about the Earth, just inches each year. These slight movements are responsible, in great part, for the earthquakes and volcanoes that happen on Earth. What is the source of energy that drives this plate movement?(1 point)
