The alternative view—in geology and geography—that Eurasia is a single continent results in a six-continent view of the world. North America and South America are separate continents, the connecting isthmus being largely the result of volcanism from relatively recent subduction tectonics. A small inset map above the main map explicitly showed for the first time the Americas being east of Asia and separated from Asia by an ocean, as opposed to just placing the Americas on the left end of the map and Asia on the right end. A craton typically consists of a continental shield surrounded by a continental platform. Some of these are fragments of Gondwana or other ancient cratonic continents: Zealandia,[85] which includes New Zealand and New Caledonia; Madagascar; the northern Mascarene Plateau, which includes the Seychelles. Apart from the current continents, the scope and meaning of the term continent includes past geological ones. However, Europe is widely considered a continent with its comparatively large land area of 10,180,000 square kilometres (3,930,000 sq mi), while South Asia, with less than half that area, is considered a subcontinent. The movement of plates has caused the formation and break-up of continents over time, including occasional formation of a supercontinent that contains most or all of the continents. Maps of this time though, still showed North America connected to Asia and showed South America as a separate land.[67].

Covering remaining 2/3rd of the plant’s surface are five oceans which formed from the super ocean, Panthalassa. This accounts for the great age of the rocks comprising the continental cratons. 6: Mêmes types de roches sur les deux continents, mêmes types (analogies) de faunes et de flores, traces de la glaciation sur les continents actuels … 7: 1960 – 1912 = 48 ans !!
