Russia is a land of superlatives. By far the world’s largest country, it covers nearly twice the territory of Canada, the second largest. It extends across the whole of northern Asia and the eastern third of Europe, spanning 11 time zones and incorporating a great range of environments and landforms, from deserts to semiarid steppes to deep forests and Arctic tundra. Russia contains Europe’s longest river, the Volga, and its largest lake, Ladoga. Russia also is home to the world’s deepest lake, Baikal, and the country recorded the world’s lowest temperature outside the North and South poles.
