Eurasia / is a combined
continental landmass of
 The term is a
portmanteau of its constituent continents (Europe and Asia). Located primarily in the
Eastern Hemispheres, it is bordered by the
Atlantic Ocean to the west, the
Pacific Ocean to the east, the
Arctic Ocean to the north, and by
Mediterranean Sea, and the
Indian Ocean to the south.
 The division between Europe and Asia as two different continents is a historical
social construct, with no clear physical separation between them; thus, in some parts of the world, Eurasia is recognized as the largest of five or six continents.
 In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on
Eurasia covers around 55,000,000 square kilometres (21,000,000 sq mi), or around 36.2% of the
Earth's total land area. The landmass contains around 5.0 billion people, equating to approximately 70% of the
human population. Humans first settled in Eurasia between 60,000 and 125,000 years ago. Some major islands, including
Ireland, and those of
Indonesia, are often included under the popular definition of Eurasia, in spite of being separate from the contiguous landmass.
Physiographically, Eurasia is a single continent.
 The concepts of
Asia as distinct continents date back to
antiquity and their borders are geologically arbitrary. In ancient times the
Black Sea and the
Sea of Marmara, along with their associated straits, were seen as separating the continents, but today the
Caucasus ranges are more seen as the main delimiters between the two. Eurasia is connected to
Africa at the
Suez Canal, and Eurasia is sometimes combined with Africa to make the largest contiguous landmass on Earth called
 Due to the vast landmass and differences in latitude, Eurasia exhibits all types of climate under the
Köppen classification, including the harshest types of hot and cold temperatures, high and low precipitation and various types of
