Here's a breakdown:

* Pangaea was a supercontinent that existed about 335 to 175 million years ago.

* Tectonic plates are large sections of the Earth's crust that move slowly over time.

* The movement of these plates is driven by convection currents in the Earth's mantle.

* The separation of Pangaea was caused by these tectonic plates moving apart, driven by the convection currents. This process, called continental drift, led to the formation of the continents and oceans we see today.

So, the movement of tectonic plates was the primary force behind the breakup of Pangaea and the subsequent formation of the continents and oceans as we know them.
