Editing North America (section)

===Geography and extent===

North America occupies the northern portion of the landmass generally referred to as the New World, the Western Hemisphere, the Americas, or simply America. America is considered a single continent in Latin America, the Iberian Peninsula, Greece, some parts of Europe and by the Olympic Committee, while North America is considered a subcontinent. North America's only land connection is to South America at the Colombia-Panama border according to most authorities, or at the Panama Canal by some and even at the Isthmus of Tehuantepec, Mexico by a few who separate Central America which rests mostly on the Caribbean Plate. Before the Central American isthmus was raised, the region had been underwater. The islands of the West Indies delineate a submerged former land bridge, which had connected North America and South America via what are now Florida and Venezuela.

The continental coastline is long and irregular. The Gulf of Mexico is the largest body of water indenting the continent, followed by Hudson Bay. Others include the Gulf of Saint Lawrence and the Gulf of California.

There are numerous islands off the continent’s coasts: principally, the Arctic Archipelago, the Bahamas, Turks & Caicos, the Greater and Lesser Antilles, the Aleutian Islands, the Alexander Archipelago, the many thousand islands of the British Columbia Coast, Newfoundland and Greenland, a self-governing Danish island, and the world's largest, is on the same tectonic plate (the North American Plate) and is part of North America geographically. Bermuda is not part of the Americas, but is an oceanic island which was formed on the fissure of the Mid-Atlantic Ridge over 100 million years ago. The nearest landmass to it is Cape Hatteras, North Carolina, and it is often thought of as part of North America, especially given its historical, political and cultural ties to Virginia and other parts of the continent.
