How do the tectonic plates move?

What is the type of movement for diagram A?

What is the type of movement for diagram B?

This type of movement causes orogenesis.

This type of movement leads to the formation of underwater mountain ranges (mid-oceanic ridges) and new oceanic crust. It can also cause earthquakes.

This type of movement causes earthquakes, but it's not usually associated with volcanic activity.
