Question
Plate tectonics js one of the most important and fundamental theories in earth science. We know today that plate boundaries are defined primarily by_______1______

The resultant zone of seismic activity in the subducted plate is known as a _________3_______ zone. Some earthquake and volcanic activity can be found within tectonic plates. Such phenomena may be attributed to rising plumes of mantle material known as_______4_______. One of the simplest and earliest mechanisms to explain the movement of the plates is______5______in the mantle.
