3. The driving forces behind plate tectonics, a subject that plagued Wegener, continue to be a matter of debate today. Which of the following is NOT a possible cause of plate motion? a. convection b. earthquake activity c. gravity d. mantle upwelling The driving forces behind plate tectonics, a subject that plagued Wegener, continue to be a matter of debate today. Which of the following is NOT a possible cause of plate motion? 4. a. convection b. earthquake activity c. gravity d. mantle upwelling

Explanation / Answer

D) Earthquake activity  

Earthquake is an effect of plate tectonics where stress within a plate develops and when it is release the siesmic activities occurs.

gravity is the driving force behind movement of plate tectonics as denser and heavier plates are subucted and lighter ones are formed over it.

Also convection cell in the mantle and the mantle upwelling due to these convection cell help in plate movements,
