3 which force powers plate tectonics? a ocean tides b volcanic eruptions c erosion of rock d convection…

Brief Explanations:

Plate tectonics is powered by convection currents in the Earth's mantle. Ocean tides are caused by gravitational forces of the moon and sun. Volcanic eruptions are a result of plate - tectonic activity rather than its power source. Erosion of rock is a surface - level process not related to powering plate tectonics.

Answer:

D. Convection currents
