Clash of the ContinentsRating: 1 likes, 0 dislikes
This is a science fiction presentation. There is very little science, and what is there is distorted by the story line of a time traveler.
Pangea is discussed, with a projection 250 million years into the future showing the formation of another supercontinent.
In order to 'punch up' the drama there is no discussion of geologic time. The Siberian Traps (vast deposits of lava) are mentioned as a cause of extinctions in Permian time. However, it took about a million years for these lavas to accumulate. It took hundreds of millions of years for Pangea to come into existence by the bumping together of continents into a supercontinent. As soon as Pangea formed it began to break apart.
The future supercontinent is proposed to be surrounded by enormous mountain ranges, the interior of the continent is supposed to be a vast desert. That doesn't match up with what really happens in the formation of a supercontinent.
Continents move with plate tectonics; plates and continents collide, and form mountains like those of the Himalayas. India bumped into Asia, the mountains are the result. The Himalayas are the earliest beginnings of the formation of a new supercontinent. They are not on the edges of the supercontinents, but in the interior. The Ural Mountains are remnants of the welding of two different continents (Europe and Asia) together to create one half of the northern part of ancient Pangea.
Clash of the Continents should be rewritten and released as a science fiction DVD.
