The Americas, which are sometimes collectively called America, are a landmass comprising the totality of North and South America. The Americas make up most of the land in Earth’s Western Hemisphere and comprise the New World. Along with their associated islands, the Americas cover 8% of Earth’s total surface area and 28.4% of its land area. The topography is dominated by the American Cordillera, a long chain of mountains that runs the length of the west coast. The flatter eastern side of the Americas is dominated by large river basins, such as the Amazon, St. Lawrence River–Great Lakes basin, Mississippi, and La Plata. Since the Americas extend 14,000 km (8,700 mi) from north to south, the climate and ecology vary widely, from the arctic tundra of Northern Canada, Greenland, and Alaska, to the tropical rain forests in Central America and South America.

NORTHERN AMERICA
Northern America is the northernmost subregion of North America. The boundaries may be drawn slightly differently. In one definition, it lies directly north of Middle America (including the Caribbean, Central America, and Mexico). Northern America’s land frontier with the rest of North America then coincides with the Mexico–United States border. Geopolitically, according to the United Nations’ scheme of geographic regions and subregions, Northern America consists of Bermuda, Canada, Greenland, Saint Pierre and Miquelon, and the United States (the contiguous United States and Alaska only, excluding Hawaii, Navassa Island, Puerto Rico, the United States Virgin Islands, and other minor U.S. Pacific territories).

CENTRAL AMERICA
Central America is a region of the Americas. It is bordered by Mexico to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America consists of seven countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. Their combined population is estimated at 44.53 million (2016).

LATIN AMERICA
Latin America is the cultural region of the Americas comprising multiple nation-states where Romance languages—languages that derived from Latin, i.e., Spanish, Portuguese, and French are predominantly spoken. The term does not have a precise definition, but it is “commonly used to describe South America, Central America, and Mexico, and the islands of the Caribbean.” A short definition of the region is Spanish America and Brazil, that is Portuguese America. The term is relatively recent, coined in the nineteenth century, used to refer to regions in the Americas that were ruled by the Spanish, Portuguese, and French empires. The term “Latin America” is broader than categories such as Hispanic America, which specifically refers to Spanish-speaking countries; and Ibero-America, which specifically refers to both Spanish and Portuguese-speaking countries.
