GEOGRAPHY!

America is the second largest land mass of the planet, after Asia.Tiene an area of approximately 42,262,209 square kilometers. It stretches from north to south from Cape Columbia (58 ° N, Canada) in the Arctic Ocean to the Islands Diego Ramirez (56 º S, Chile), located in the Drake Passage that separates the American continent of Antarctica. Its easternmost point corresponds to Cabo Branco in Brazil (34 ° 47'W), while the westernmost corresponds to the island Attu in the Aleutian Islands (173 ° 11'E), near the Bering Strait that separates Alaska from the mainland Asia. Is composed of three subcontinents: North America and South America, Central America. According to the theories of continental drift and plate tectonics, both land masses have remained apart over millions of years. After the division of Gondwana and Laurasia subcontinents both allegedly traveled to their current positions by being united Central America, a land bridge emerged between them by the action of plate tectonics, which was first an island arc and later became continuous land . The thinnest point of this union is the Isthmus of Panama formed 3 million years ago. Another island arc, the West Indies, is a second connection between the subcontinents.
