What is Pangaea?

What is Pangaea?

• A. A small mineral deposit.
• B. The supercontinent that formed millions of years ago, about 542 mya at the end of the Paleozoic era.
• C. The name of a mountain range.
• D. A type of sediment.

Answer: (B)

Pangaea was a supercontinent—the idea that most of Earth's landmasses were joined into a single huge landmass. It formed during the late Paleozoic Era, roughly 335 to 300 million years ago, and began to break apart in the early Mesozoic, about 175 million years ago, eventually giving rise to the continents we know today. The concept comes from observations that coastlines fit together like puzzle pieces and that similar fossils and rock formations line up across distant continents, along with clues from ancient climates. Inside Pangaea, there were northern and southern regions known as Laurasia and Gondwana, which over tens of millions of years drifted apart to become the individual continents. This fits with plate tectonics, the idea that large lithospheric plates move and interact, reshaping Earth's surface over geologic time. For context, the date 542 million years ago is from the Cambrian period, not when Pangaea formed. Pangaea’s existence sits later in the geological timeline, during the late Paleozoic to early Mesozoic eras.
