2. Location: Pangaea straddled the equator and extended from north to south, with the North Pole at one end and the South Pole at the other.
3. Climate: Pangaea had a wide range of climatic conditions due to its vast size. The interior regions were hot and dry, while the coastal areas experienced more moderate climates.
Panthalassa:
1. Ocean: Panthalassa was the vast global ocean that surrounded Pangaea. It covered more than 70% of the Earth's surface and was the largest ocean in Earth's history.
2. Location: Panthalassa encircled Pangaea, covering most of the Earth's surface.
3. Marine Life: Panthalassa was teeming with marine life. It was home to a diverse range of marine organisms, including ancient fish, reptiles, and other aquatic species.
In summary, Pangaea was the supercontinent that existed during the late Paleozoic and early Mesozoic eras, while Panthalassa was the global ocean that surrounded Pangaea. Pangaea was characterized by its vast size and diverse climates, while Panthalassa was the largest and most expansive ocean in Earth's history.
