How to tectonic plates move?

Tectonic plates shift in diffrent ways

Explanation:

Transform--where plates essentially grind past each other with no subduction.

Convergent--where plates collide. Oceanic plate to oceanic plate convergence will result in the more dense plate subducting under the less dense plate.

Divergent--where plates move apart. The major diverging plates are located at the mid-ocean ridge system where melting material from the asthenosphere fills in the separating plate zone, creating new crust.

There you go.
