Question

alfred wegeners idea of continental drift was not immediately accepted by the scientific world. after wegeners death, scientists built on his work to explain how continents could move over time. which process did scientists determine to be reason for plate tectonic activity? a. mountain building b. magnetic reversals c. superposition d. convection currents

Explanation:

Convection currents in the mantle are the driving force behind plate tectonic activity. Heat from the Earth's interior causes the mantle material to move in a circular - like motion, which in turn moves the tectonic plates. Mountain building is a result of plate - plate interactions, magnetic reversals are related to the Earth's magnetic field, and superposition is a principle in geology related to rock layers, not the cause of plate tectonic activity.

Answer:

D. convection currents
