Professor P. Cavud at a conference in California, confirming the theory of the acceleration of the continental drift, talked about the history of the movement of the continents and the period of stability of the continental plates. It coincided with the time period of the existence of one continent, Rodinia. This is over 1.1 billion years ago.
For almost 400 million years, the movement stopped. The earth has cooled down and has reached a balance in the temperatures of the core and the external environment. The slow sinking of one continental plate under another led to drift and even its acceleration. The subduction zones that appeared gave rise to tectonic activity, which led to the disintegration of the continent, the release of new chemical elements into water and air, and, possibly, to the evolution of life on Earth.
After 300 million years, the Earth was divided by four continents:
- Part of modern Europe.
- Partial territory of North America.
- Angara – modern Asia.
- Gondwana is a complex of southern continents.
Further movement pushed the first two plates into Euro-America, which after 100 million years collided with the Angara. This is how Laurasia was formed. Having overcome the distance of the waters of the ancient sea of Tethys, the last two continents collided, forming one piece of land – Pangea.
It took less than 100 million years to record the first disintegration of Pangea and less than 180 million years before the complete disintegration and the formation of the present geographical position of the continents.
All collisions were accompanied by the heaving of rocks and the formation of mountain lines. Appalachian Mountains and Ural Mountains, mountains of Scotland. North America, etc. Careful study of their rocks, the coincidence in their composition, confirms the theory of collision of tectonic plates. Such a coincidence in the rocks in places of supposed continental ruptures plays into the hands of geologists and seekers who predict the presence of one rock on different continents.
