Physical features of China include deserts, plateaus, grasslands, tropics, mountains and rivers, with the majority of the land being mountainous, high and hilly. The elevation is high in the west and lowers dramatically toward the east of the country.
The highest, most mountainous part of China is the southwestern border at India and Nepal. This area, which includes the Himalayas, is the highest location on the planet and the home of Mount Everest. The Himalayas gradually make way for other mountain ranges. The Kunlun Mountains are in the center west area and the Tiahang Mountains are in the center north area. Greater Hinggan Mountains lie in the northeast while the Hengduan Mountains in the southeast. The Qinling Mountains act as a barrier between the north and the south of the country. Other than mountains, China has tropics in the south, desert plateaus to the west and grasslands to the north.
Rivers are another important physical feature in China. The largest river is the Yangtze River, which flows from Tibet to the East China Sea along a staggering 4,000-mile route. The Yellow River flows through northern China to the Bohai Sea, and the Black Dragon River marks the border between Russia and China.
