The name given to the single super-continent that existed 200 million years ago is Pangaea. Pangaea was a massive landmass that incorporated almost all of Earth's landmasses, forming one unified continent.

Pangaea, meaning "all lands" in Greek, was first proposed by Alfred Wegener, a German meteorologist and geophysicist, in the early 20th century. He proposed the theory of continental drift, suggesting that the continents were once joined together and have since drifted apart.

The formation of Pangaea occurred during the late Paleozoic and early Mesozoic eras and lasted for millions of years. It began to break apart around 175 million years ago, leading to the formation of the continents we know today. The breakup of Pangaea resulted in the formation of the current continents and the creation of the Atlantic Ocean.

During the time when Pangaea existed, the Earth looked drastically different. The super-continent was surrounded by a single vast ocean called Panthalassa. The climate on Pangaea varied from arid desert regions to lush tropical rainforests. The interior of Pangaea was mostly dry and arid, while the coastal regions experienced more moderate climates.

The separation of Pangaea had profound effects on the Earth's ecosystems. As the continents drifted apart, different species became isolated from one another, leading to the evolution of unique flora and fauna in different regions. The breakup of Pangaea also influenced the patterns of ocean currents and climate, shaping the Earth's climate system as we know it today.

Scientists have been able to reconstruct the existence of Pangaea through various lines of evidence, including matching coastlines, rock formations, and fossil records. The study of Pangaea and its breakup has greatly contributed to our understanding of Earth's geological history and the processes that shape our planet.

In conclusion, Pangaea was the name given to the single super-continent that existed 200 million years ago. Its formation and subsequent breakup had a profound impact on the Earth's geological history and the evolution of life on our planet.
