It is mainly divided into three aspects:
1. The "thin end" between the two continents (the dividing line between North America and South America is the "Panama Canal", the dividing line between Asia and Africa The dividing line is the "Canal Suez”, and the dividing line between Asia and North America is the “Bering Strait”
2. two).North and South America and Europe (no) are the "Atlantic", the dividing line between Europe and Africa is the "Mediterranean Sea", the dividing line between the North and South America and Australia (Asia) is the "Pacific Ocean" and the dividing line between Australia and Africa is the "Indian Ocean");
3. Divided by mountains, climate, history and culture (Europe and Asia, Asia and Australia)
The division of Europe and Asia is determinede depending on the different natural conditions of the two places. The two continents are divided by the Ural Mountains, the Ural River, the Caspian Sea, the Caucasus Mountains, the Black Sea, the Bosphorus and the Dardanelles Strait.
The concept and scope of the name of the continent Oceania are more complicated than those of the other six continents on the planet. There is still no internationally recognized and unified explanation. Most Chinese geographers think that Oceania refers to the general name of Pacific islands that do not belong to other continents. It consists of 4 parts: Australasia, Melanesia, Micronesia and Polynesia. The name Oceania first appeared around 1812, named by the Danish geographer Malte Bronn. At that time, it only referred to the three main islands of Melanesia, Micronesia and Polynesia. This was Oceania in the narrow sense.
4. Antarctica is mainement divided into oceans and climates, and no one lives here, and no one has been active here for a long time (scientific researchers are conducting a short-term investigation). The name of Antarctica is Antarctica, which comes from the Greek anti (opposite), plus Arctic (North Pole), this means the opposite of the North Pole, that is, the South Pole. Because the continent is located at the southern tip of the earth, around Antarctica, it is called "Antarctica" in Chinese, which is a place name consistent with the geographical location. Antarctica was discovered by the Frenchman Bouvet in 1738. During his journey, he discovered an island near the Antarctic continent (today's Bouvet Island). The Englishman Cook visited many islands around the Antarctic continent from 172 to 1775. However, it is now generally accepted that Antarctica was discovered in the 19th century. Americans are said to have first sighted Antarctica in 1820.
