Eurasiaa
Eurasia is the largest continental region of Earth, comprising the contiguous landmasses of Europe and Asia. Geographically, the boundary between Europe and Asia is not universally defined, but a common convention places it along the Ural Mountains, the Ural River, the Caspian Sea, the Caucasus Mountains, and the Black Sea. This vast landmass encompasses a diverse range of climates, terrains, and ecosystems, from the Arctic tundra in the north to tropical rainforests in the south. Eurasia is home to the majority of the world's population and a significant portion of its biodiversity. Historically, Eurasia has been a cradle of civilization, with many of the world's earliest and most influential cultures developing within its boundaries. Its extensive land routes, such as the Silk Road, facilitated trade, cultural exchange, and the spread of ideas and technologies between different regions for millennia. Politically, Eurasia is comprised of numerous countries, each with its own distinct history, culture, and governmental systems. The sheer scale and diversity of Eurasia make it a region of immense importance in global affairs.
