North America consist the northern portion of the island generally called as the New World, the Western Hemisphere, the Americas, or simply America. North America’s only territory contact to South America is at the Isthmus of Panama. The continent is circled on the southeast by most geographers at the Darién divide along the Colombia-Panama border, placing all of Panama within North America. On the other hand, less ordinary views would end North America at the artificial Panama Canal, and some geologists physiographic locate its southern limit at the Isthmus of Tehuantepec, Mexico, with Central America broaden southeastward to South America from this point. The Caribbean islands, or West Indies, are measure part of North America.
Before the Central American cape was move up, the state had been underwater. The islands of the West Indies set down a waterlogged former land bridge which had associated North America and South America via what are at the present Florida and Venezuela. The continental shoreline is extensive and asymmetrical. The Gulf of Mexico is the major bodies of water indent the continent, subsequently Hudson Bay. Others incorporate the Gulf of Saint Lawrence and the Gulf of California.
There are copious islands off the continent’s coasts, mainly, the Arctic Archipelago, the Bahamas, Turks & Caicos, the superior and minor Antilles, the Aleutian Islands, the Alexander Archipelago, the numerous thousand islands of the British Columbia Coast, and Newfoundland. Greenland, an autonomous Danish island, and the world’s biggest, is on the identical tectonic plate and is part of North America geographically. In a geologic intelligence, Bermuda is not part of the Americas, but an oceanic island which was shaped on the split of the Mid-Atlantic Ridge over 100 million years before. The adjoining landmass to it is Cape Hatteras, North Carolina. However, Bermuda is repeatedly consideration of as part of North America, particularly given its historical, political and cultural ties to Virginia and other parts of the continent.
The huge mainstream of North America is on the North American Plate. Division of California and western Mexico form the biased edge of the Pacific Plate, with the two plates gathering along the San Andreas Fault. The southernmost section of the continent and much of the West Indies recline on the Caribbean Plate, whereas the Juan de Fuca and Cocos plates limit the North American Plate on its western frontier.
