Pangea

Pangea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras, about 335 to 175 million years ago. The name Pangea is derived from the Greek words "pan," meaning all, and "gea," meaning Earth. It was a massive landmass that consisted of most of the Earth's continents as we know them today.

Formation of Pangea

According to the theory of plate tectonics, Pangea formed through the process of continental drift. This theory suggests that Earth's outer shell is divided into several plates that move and interact with each other over time. About 300 million years ago, these plates began to converge, bringing the continents together to form Pangea.

Evidence of Pangea

There are several lines of evidence that support the existence of Pangea. Fossil evidence, such as similar plant and animal species found on continents that are now separated by oceans, suggests that these landmasses were once connected. Additionally, geological features, such as matching rock formations and mountain ranges on different continents, provide further evidence of Pangea's existence.

Breakup of Pangea

Pangea began to break apart around 175 million years ago, leading to the formation of the continents as we know them today. This breakup resulted in the formation of the Atlantic Ocean as the landmasses moved away from each other.
