Pangea, a reputation derived from Greek, actually interprets to “all land.” It represents a pivotal interval in Earth’s geological historical past, when all continents had been fused right into a single, interconnected landmass. This supercontinent existed in the course of the late Paleozoic and early Mesozoic eras, roughly 335 million to 175 million years in the past.
Pangea’s formation resulted from the gradual convergence of Earth’s tectonic plates, pushed by the planet’s inner forces. As continents collided, they merged collectively, forming a colossal landmass that spanned from pole to pole. This supercontinent had a profound impression on Earth’s local weather, ecosystems, and geological processes.
To delve deeper into the intriguing world of Pangea, let’s discover its key traits, the forces that formed its formation and breakup, and the lasting legacy it left on our planet.
