Eurasia is the largest continental area on Earth, comprising all of Europe as alive as Asia. Primarily in the Northern in addition to Eastern Hemispheres, it spans from the British Isles in addition to the Iberian Peninsula in the west to the Japanese archipelago and the Russian Far East in the east. The continental landmass is bordered by the Atlantic Ocean and Africa to the west, the Pacific Ocean to the east, the Arctic Ocean to the north, and by Africa, the Mediterranean Sea, and the Indian Ocean to the south. The division between Europe and Asia as two continents is a historical social construct, as numerous of their borders are over land; thus, in some parts of the world, Eurasia is recognized as the largest of the six, five, or four continents on Earth. In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on paleomagnetic data.

Eurasia covers around 55,000,000 square kilometres 21,000,000 sq mi, or around 36.2% of the human population. Humans number one settled in Eurasia between 60,000 and 125,000 years ago. Some major islands, including Great Britain, Iceland, Ireland, and Sri Lanka, as living as those of Japan, the Philippines, and most of Indonesia, are often transmitted in the popular definition of Eurasia, despite being separate from the contiguous landmass.

According to some geographers physiographically, Eurasia is a single continent. The theory of Europe and Asia as distinct continents date back to antiquity, and their borders are geologically arbitrary and name historically been referenced to occasional change. Eurasia is connected to Africa at the Suez Canal, and Eurasia is sometimes combined with Africa to pretend the largest contiguous landmass on Earth called Afro-Eurasia. Due to the vast landmass and differences in latitude, Eurasia exhibits all style of climate under the Köppen classification, including the harshest race of hot and cold temperatures, high and low precipitation and various types of ecosystems.

Geology

Eurasia formed between 375 and 325 million years ago with the merging of Siberia, Kazakhstania, and Baltica, which was joined to Laurentia, now North America, to form Euramerica. Chinese cratons collided with Siberia's southern coast.
