If Pangaea had never broken up, the Earth's processes, landforms, and environments would be vastly different than what they presently are. As the book states, "Everything living on Earth is affected by plate tectonics" (48). And without Pangaea's break up, these large-scale geologic processes might not occur.
As the plates move a few centimeters every year, so do the continents and ocean basins. This creates natural resource zones of oil, gas, and other minerals, and it also forms earthquakes and volcanoes. If Pangaea still existed, these zones might not exist or would be located in vastly different places, and perhaps there would be no earthquakes or volcanoes.
Along those lines, without the breakup of Pangaea, there wouldn't be the
