Along the diverging plate boundary, what are the little slips that occur called?
Transform faults
What is the reason for the long linear lines along the mid-atlantic ridge?
The plates rotate in other directions too
Why are the transform faults named so?

What influences how fast a plate moves, and why is the Pacific plate moving faster than others?
Both the convection and the subduction, and because it is bigger and more active
What causes earthquakes and volcanic eruptions along the Pacific Ocean, and why are these regions prone to them?
The subduction of the Pacific plate, and because it is the most active
