How many parts of the United States? What's the full name? Where is the Panama Canal?

America is located in the western hemisphere, divided into North America, Central America and South America, with an area of 42.068 million square kilometers, accounting for 8.3% of the earth's surface area and 28.4% of the land area. For Native American Indians, America is not a new continent. They reached the American continent as early as 40,000 years ago, crossed the Bering Strait from Asia to America about 40,000 years ago, or crossed the frozen strait continental bridge. Columbus's arrival in America only had a great influence on the western world. Indians and westerners are both human beings, so it was Indians who first discovered the new continent, but their discovery had little impact. Whether Columbus or other westerners landed on the American continent, it was not the "first discovery". Before they came, there were not only tens of millions of residents here, but also Asians had already landed on American land before them. It's just that they Asians are not here to expand their sphere of influence and plunder colonies, but to find a place to live or avoid disasters, cultural exchanges or commercial trade. This is a peaceful migration or exploration, in sharp contrast with Columbus and later western colonists. [656] Columbus was not the first person to discover America, but he reached a "new world" that he thought he had never been to. The "New World" is just a "New World" for Columbus and westerners. Human geography divides it into Angles (mostly English) and Latin America (mostly Spanish and Portuguese). There are about 900 million residents in the United States, accounting for 13.5% of the total population. For the Indo-European civilization, America was unknown at first, but it was later arrived by the navigator Columbus in 1492, and was mistaken for India, so that today the locals are called Indians. It was named after the Italian explorer Amerigo Wesp, and it has been used ever since. Spain and Portugal first immigrated to the United States, and later the Netherlands, Britain and France also immigrated there. 1776, the United States was the first western colonial independent country-the United States.

America includes North America and South America, collectively known as America.

Name source

The name of America [2] is generally said to commemorate a famous Italian navigator named Amerigo Weiss Pucci, an Italian businessman and cartographer who explored the east coast of South America and the Caribbean, and he was the first person to draw a map of the new continent. His name is written in Latin: americus vespucius. Because the names used in other continents are all negative Latin. Therefore, Americus has become a feminine Latin word: America. 1499. Yamei named the New World after Amerigo.

Rico sailed from the sea to India with a fleet led by Portuguese ojeda. They sailed along the route taken by Columbus, overcame many difficulties and finally reached the American continent. Amerigo made a detailed investigation on the northeast coast of South America and compiled the latest map. 1507, his book Sea Travel Tales came out, which caused a sensation all over the world. In this book, the process of "discovering" the new continent is described in a fascinating way, and the mainland is described and rendered vividly. Amerigo announced the concept of the new continent to the world, and washed away the earth structure system formulated by the absolute authority of western geography in the Middle Ages. Therefore, several French scholars revised and supplemented Doremus's masterpiece Cosmology, and named the New World after Amerigo in recognition of his outstanding contribution to human understanding of the world. After the publication of the new book Cosmology, according to the materials in the book, a new continent, Amerigo, was added to the map. Later, according to the word formation form of other continents, "Amerigo" was changed to "Americana". At first, the name was just a guide to America, and through the Mercator map of 154 1, North America was also a part of America. Some people think: "In English, America and America are the same word' America', but the Chinese translation is different. The former refers to the whole America, and the latter refers to the United States. " This is completely wrong. If you have a little knowledge of logic and history, you should know that the word America existed before the birth of America. How can you say that Chinese translation is different? So the word America is used by Americans to address the whole United States after its birth. Americans often say that "God bless America" means God bless America, not God bless America. Americans mean Americans, including Canadians, Mexicans and Americans. But since the independence of the United States, it only refers to Americans now.

South America has a mild climate. Underground resources are very rich, and non-ferrous metals such as coal, iron, oil, copper and nickel all occupy an important position in the world. From the end of15th century, Spain, Portugal, Britain, France and other countries explored and colonized. 1776 The United States declared independence.
