Old land

 When looking comprehensively to the model of the globe as a whole can easily note the great similarity in the form of edges and coastal areas of the continents of the seven components of the Earth, and the possibility of compatibility with each other and transform it into a continental one block and huge if they were collected with each other, and to compensate the gaps of missing ones, as exactly happens when collecting pieces puncture, and this principle, the scientists and biologists specialists interested in the affairs of the globe in the past and all of the newly swung hypothesis, which says that the earth was composed of an old flat one continental huge, in addition to the surrounding water from each side They also put several hypotheses to explain why the separation of this flat section of the continental mass to several continents, and looked for evidence and evidence that make sure the health of their words. The hypothesis of continental separation The scientists put more than one hypothesis to explain the separation of continents and their separation from each other and the separation of different bodies of water from the sea and the intertwined between them, Perhaps the most common and accepted assumptions is the impact of the Earth in ancient celestial bodies of huge size and was heading towards the Earth at high speed, which caused In the fracturing and separation of inland layers of land in several regions, known as the coastline of each continent, in addition to land in some areas, which contributed to the formation of small islands and continental islands, as is the case with Australia, Scientists believe that the extinction of dinosaurs from the Earth was due to this impact, and the evidence that confirms the validity of this theory and make them more acceptable are as follows. Rocky formation, scientists have been able to prove the similarity and congruence in composition and rocky structures of the edges of the continents that they believe were one part before the impact, as is the case with the eastern edges of the South American continent and the corresponding western edges of the African continent, as well as the edges of the Indian plateau and the western edges of the continent Australia, the edges of the British Isles and some areas of the European continent. Species dispersion, through the advanced studies of the origins of some types of animals, which confirmed the same origin and corresponding to some types of animals that cause continental separation in dispersion and away from each other, and other conditions of adaptation, which caused a slight change in some of their characteristics and characteristics. The species pool, which happened after the return of the two continents of the Americas to connect with each other after the huge continental separation, causing the return of some species of animals and objects to assemble together again.
