Is it possible for a tectonic plate to break in half?

The main tectonic plates are enormous. What's stopping them from snapping in the middle to form two or three smaller plates?

Plates can and do get broken up, such as through the formation and widening of rifts. That's how the Pangea supercontinent was broken up into several new continets/tectonic plates. That's how Africa will eventually split off into two separate continents (the main part of Africa which will eventually drive into Europe and the Easternmost part of Africa which will drift farther into the Indian ocean).
