Americas, also called America, comprise the two continents, North and South America, of the Western Hemisphere.
North America: North America is ranked as the third largest continent. It is located to the north of the planet earth as its name suggests and it is bordered by the Pacific Ocean, the Atlantic Ocean, and the Arctic Ocean to the west, east and to the north respectively. It is made up of twenty-four countries with a total population of 579, 024,000 people, the United States is the most populated nation with a population of 321.2 million people. The indigenous North Americans are believed to be Asians who arrived in North America by crossing from North East Asia. Since then the population has grown dramatically making North America be the fourth most populated continent after Asia, Africa, and Europe.
South America: The most significant part of this continent lies in the Southern Hemisphere. Some geographers argue that South America is a subcontinent of the Americas, but this is disputed as South America is a planet of its own. It is bordered by the Pacific and the Atlantic Ocean to the south and west respectively. It is ranked as the fourth largest continent covering an approximate area of 15.53 million square kilometers, just a little bit smaller than North America. South America has a total population of 422, 500, 000 people, Brazil being the most populated country with an estimated population of 207.7 million people.
The Americas can be roughly divided into two major cultural regions: Latin America, which includes North America south of the Rio Grande, the islands of the West Indies, and all of South America; and Anglo-America, which includes Canada and the United States. The term Middle America is sometimes used to designate Mexico, Central America, and the West Indies collectively.
Although the two continents are all located in the western hemisphere, they cannot be described as being one continent due to various reasons. Despite the fact that they are both positioned in the western hemisphere, North America is situated to the Arctic (Northern) Hemisphere while South America is placed below the equator, i.e., to the Southern Hemisphere. The two continents are commonly referred to as the Americas and are separated by ocean waters, and North America is larger than South America.
The climatic zones of the two continents are quite different. In North America, subarctic climate prevails in the north, gradually warming southward and finally becoming tropical near the southern isthmus. In South America, the climate in the north is tropical, becoming cooler southward, and finally becoming a cold, marine climate at Cape Horn.
North America is the fourth most populated continent while South America is the fifth. The Paleo-Indians initially inhabited the two continents in the 18,000 BC. Although the same people previously occupied the two continents, they differ in the predominant languages spoken today. The languages that are common in North America include English, Spanish, and French while South Americans commonly speak Portuguese and Spanish.
About 400 million people in the Americas speak Spanish as their First Language. 247 million people speak English as their mother tongue, 204 million people speak Brazilian Portuguese, about 8 million people speak French or French Creole.
