The ancient continent that is said to be submerged is known as Pangaea. Pangaea, which means "all lands" in Greek, was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It is believed to have formed about 300 million years ago and began to break apart around 175 million years ago.

Pangaea was a massive landmass that encompassed almost all of Earth's current continental plates. It brought together what are now known as South America, Africa, North America, Europe, Asia, and Australia, forming a single, unified landmass. This supercontinent was surrounded by a vast ocean called Panthalassa.

The theory of Pangaea was proposed by German meteorologist and geophysicist Alfred Wegener in the early 20th century. Wegener noticed that the coastlines of South America and Africa seemed to fit together like puzzle pieces, and he began to speculate that these continents were once connected.

As more evidence emerged, scientists began to piece together the history of Pangaea. Fossil records showed similarities in plant and animal species that lived on opposite sides of the Atlantic Ocean, further supporting the theory of a once-unified landmass. Additionally, rock formations and mountain ranges aligned when the continents were brought together, providing further evidence of their former connection.

Over millions of years, Pangaea began to break apart due to tectonic plate movements. This process, known as continental drift, is driven by the movement of molten rock beneath Earth's surface. As the plates shifted, Pangaea split into smaller continents, which eventually formed the continents we know today.

Although Pangaea no longer exists as a single landmass, its legacy can still be seen in the geological features of Earth. The Atlantic Ocean, for example, is widening as North America moves away from Europe and South America drifts away from Africa. The remnants of Pangaea serve as a reminder of the ever-changing nature of our planet.
