What was the name of the supercontinent that existed before continents separated?

The supercontinent that existed before the separation of continents is known as Pangaea. Formed during the late Paleozoic and early Mesozoic eras, approximately 335 million years ago, Pangaea brought together most of the Earth's landmasses into a single, massive continent. This geological event significantly impacted global climate, sea levels, and the distribution of ecosystems.

The term "Pangaea" translates to "all lands," reflecting its vast extent. It began to break apart around 175 million years ago, leading to the formation of the modern continents we recognize today. The separation of Pangaea is a key concept in plate tectonics, illustrating how plates drift over time due to convection currents in the Earth's mantle, reshaping the planet's surface.

While Gondwana and Laurasia were indeed significant landmasses that existed during periods of geological history, they are not referred to as supercontinents in their own right in the same context as Pangaea. Atlantis, often considered a mythical place, has no basis in geological history. The recognition of Pangaea is crucial for understanding the processes of continental drift and the historical arrangement of Earth's landmasses.
