This process, which began in the Triassic, continued throughout the Jurassic and led to the formation of the modern continents. Here's why this event is considered major:

* Formation of new oceans: The splitting of Pangaea created vast new ocean basins, such as the Atlantic Ocean.

* Volcanic activity: The breakup of continents caused extensive volcanic activity, contributing to significant changes in the Earth's climate and atmosphere.

* Changes in ocean currents: The formation of new oceans and the movement of continents altered ocean currents, leading to changes in the distribution of marine life.

* Evolutionary diversification: The breakup of Pangaea isolated populations of organisms, leading to the diversification of plant and animal life.

The Jurassic Period was a time of significant tectonic activity and dramatic landscape changes. The breakup of Pangaea had a profound impact on Earth's geology, climate, and the evolution of life.
