5. Describe Pangaea. When did Pangaea form?

Pangaea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It was a massive landmass that consisted of all the continents joined together, forming a single landmass. Pangaea began to form around 335 million years ago and existed until about 175 million years ago.During the time when Pangaea existed, the continents were all connected, and there was no ocean separating them. This allowed for the exchange of plants, animals, and other organisms between the different landmasses. The formation of Pangaea had a significant impact on the climate and geography of the Earth, as it resulted in the creation of large deserts and the formation of mountain ranges.The concept of Pangaea is important in the study of plate tectonics, which is the theory that explains the movement of the Earth's lithospheric plates. The movement of these plates over millions of years led to the breakup of Pangaea and the formation of the continents as we know them today.
