North America is divided into several main parts that help us understand its geography and cultures. One way to split the continent is into Middle America (Mexico, Central America, and the Caribbean) and Northern America (Canada, the United States, and Greenland). People also talk about Anglo-America, where English is common, and Latin America, where Spanish and Portuguese are common.
Within countries there are smaller regions. For example, Canada has areas like Atlantic Canada and the Prairies, and the United States has regions like New England and the Pacific states. Some regions, like the Great Lakes or the Pacific Northwest, cross the border between the U.S. and Canada. Trade and history help shape these regions, too.
