Visions of Continental Drift on Fast Forward
Jan 12th
What would continental drift look like on extreme fast-forward. These video clips are partly based on science, partly imagination. The (pre)historical part of these videos are hopefully based on research by Geologists. The predictions beyond the present day can be no more than pure speculation (especially this one that envisages a pangaea (single land mass) once more … almost poetic …
This second one is confusing. Some good views of how continental drift might have looked, but then the predictions of the future seem to abandon continental drift altogether, as though that fundamental process stops altogether, and switches entirely to speculation of how today’s static continents would look if sea levels continue to rise to new, extreme levels. On that basis, the title ‘Earth 100 Million years From Now’ is disappointing – where’s the continental drift gone? Sea level fluctuations would most likely be cycling rapidly (in such a geological timescale) both up and back down. Misleading, therefore, but interesting for the early section …
