Question 1
Briefly explain how magnetic patterns on the seafloor support Plate Tectonic theory.
Question 2

◦ otherwise they would have earthquakes all the time
◦ elastic rebound occurs on faults
◦ high confining pressure increases friction on the fault
◦ earthquakes only form when the rocks are free to move
◦ major faults occur at plate boundaries that only move occasionally
