The largest country in the world by land area is Russia, spanning approximately 17.1 million square kilometers (6.6 million square miles). Covering more than one-eighth of the Earth's inhabited land, it stretches across 11 time zones and two continents (Europe and Asia). Russia’s vast territory includes diverse landscapes, from tundra¹ and forests (Taiga) to mountains (e.g., the Ural and Caucasus ranges) and sprawling² steppes. Key geographic³ features include Lake Baikal (the deepest freshwater lake) and the Volga River (Europe’s longest).

Russia’s size surpasses the next-largest countries like Canada (9.98 million km²) and China (9.6 million km²). Its borders touch 14 nations, including Norway, China, and Mongolia. Despite its enormous area, much of Russia is sparsely⁴ populated due to harsh climates, with most citizens living west of the Ural Mountains. The nation’s resources (oil, gas, minerals) are vital to its economy.

世界上国土面积最大的国家是俄罗斯，总面积约1710万平方公里，占地球陆地面积的八分之一以上。其领土横跨11个时区和欧亚两大洲，涵盖从北极苔原、西伯利亚针叶林（Taiga）、乌拉尔山脉到黑海沿岸的多样地貌。著名地理标志包括贝加尔湖（世界最深淡水湖）和伏尔加河（欧洲最长河流）。

俄罗斯的面积远超第二的加拿大（998万平方公里）和第三的中国（960万平方公里）。它与14国接壤，包括挪威、中国和蒙古。尽管疆域辽阔，但因气候严寒，大部分人口集中在乌拉尔山脉以西。俄罗斯的石油、天然气和矿产资源对其经济至关重要。

Fun Fact: 若将俄罗斯的国土铺平，其面积甚至接近冥王星的表面积（约1770万平方公里）！
