What is the name of the supercontinent that encompassed almost all the landmasses on Earth?

The name of the supercontinent that encompassed nearly all the landmasses on Earth is Pangaea. This massive landmass existed during the late Paleozoic and early Mesozoic eras, approximately 335 to 175 million years ago. Pangaea is significant because it represents a time when the continents were joined together, creating a vast single land area surrounded by a global ocean called Panthalassa.

The formation of Pangaea had profound implications for the Earth's climate, biodiversity, and the geological processes that shaped the planet. It began to break apart during the Mesozoic era, leading to the formation of the continents as we know them today. This process of continental drift plays a crucial role in understanding the history of Earth's geology and the evolution of life on our planet.

In contrast, Gondwana, Laurasia, and Rodinia refer to different supercontinents from various geological periods. Gondwana was primarily made up of the southern continents, Laurasia comprised the northern continents, and Rodinia is older and formed before Pangaea. Thus, it is Pangaea that is recognized for hosting almost all of Earth’s landmasses at its peak.
