China has a diverse landscape that includes mountains, deserts, plains, and rivers. Mountains cover one-third of the country and include the high-altitude Plateau of Tibet. Deserts like the Taklamakan and Gobi are very hot and dry. Plains along the coast are fertile and home to most of China's large population. Major rivers include the Yellow River, known as "China's Sorrow" due to its destructive flooding, and the Yangtze River, where a massive new dam is being constructed to control floods. Climate varies widely due to geography but is influenced by monsoons along coastal areas.
