Why are North America and South America separate continents?
North America and South America are separate continents, the connecting isthmus being largely the result of volcanism from relatively recent subduction tectonics.
When did America split into two continents?
Roughly 1.1 billion years ago, America tried to rip itself in half. The Midcontinental Rift System nearly created a continent far different than the one we know today. A nearly 2,000 mile gash in the Earth undercut the Great Lakes. This could have been the seed for a new ocean.
What is the dividing line between North America and South America?

Is America split into 2 continents?
Americas, also called America, the two continents, North and South America, of the Western Hemisphere. The climatic zones of the two continents are quite different. In North America, subarctic climate prevails in the north, gradually warming southward and finally becoming tropical near the southern isthmus.
Who proved that America is a separate continent?
Amerigo Vespucci

When did north and South split?
about 3 million years ago
By about 3 million years ago, an isthmus had formed between North and South America. (An “isthmus” is a narrow strip of land, with water on either side, that connects two larger bodies of land.)
How were the continents divided?
Today, we know that the continents rest on massive slabs of rock called tectonic plates. The North American and Eurasian tectonic plates, for example, are separated by the Mid-Atlantic Ridge. The two continents are moving away from each other at the rate of about 2.5 centimeters (1 inch) per year.
Which countries belong to two continents?
