Сибирь, or Siberia, is a vast region in Russia, covering about 5 million square miles. It stretches from the Ural Mountains in the west to the Pacific Ocean in the east. Known for its harsh climate, Siberia experiences long, cold winters and short, warm summers. The region is rich in natural resources, including oil, natural gas, and minerals. Siberia is home to diverse landscapes, such as taiga forests, tundra, and mountain ranges. It also hosts several major rivers, including the Ob and Lena. The population is sparse, with cities like Novosibirsk and Irkutsk serving as key urban centers.
