East Asia is home to long rivers, high plateaus, dry deserts, and rugged mountains. East Asia is similar to South Asia because rugged mountains and hazardous deserts create a deadly barrier to foreigners. For thousands of years, East Asian people were isolated from the rest of the world—this allowed them to develop their culture in a very unique way. Mountains dominate East Asia’s western landscape. The Himalaya Mountains are the southern border between China and India. The Plateau of Tibet is on the Chinese side of the Himalaya Mountains. Like the Himalaya Mountains, the Plateau of Tibet was also formed by the slow crash of the Indian subcontinent into Asia. Another Mountain range in western China is the Tian Shan. The name Tian Shan means “heavenly mountains”.
East Asia also has dry areas. The Gobi Desert is found along the border between Mongolia and China. The Gobi is the 5th largest desert in the world and is also the coldest. It is common to see frost or even snow on the sand and gravel dunes. Most of western China is very dry because of the rain shadow created by the Himalaya Mountains. A rain shadow is a dry area on the leeward (opposite of windward) side of a mountainous area. The mountains block rain-producing weather and cast a "shadow" of dryness behind them. The Taklimakan Desert is found in the dry west. It is framed by the Kunlun to the south and the Tian Shan to the north. There is very little water in the Taklimakan and crossing it is extremely hazardous. The mountains and deserts have played an important role in Asian history since they created natural barriers to outsiders.
Despite the dry and mountainous terrain of East Asia, there are some low plains suitable for early civilization. The North China Plain is an alluvial plain found along the Huang River on the east coast of China. Alluvial means its made of rich soil deposited by a flooding river. The North China Plain is the main area where farming is done in China. The main food grown in China is rice. Rice grows best in warm areas that have flooded fields—often called rice paddies. Since rice produces more food per acre than wheat, it can support a much higher population.
Heavy summer rains and snowmelt support 2 large river systems in East Asia. The Huang He or Yellow River is the 6th longest river in the world. It is called the Yellow River because the water picks up yellowish loess or silt from the western half of the river. The river is known for the amount of silt or small pieces of dirt it carries. Geographers estimate about 1.4 billion tons of silt flow into the Yellow Sea. Along the Huang in the North China Plain is where China’s early civilization began. The River is also called “China’s Sorrow” because of its deadly floods.
East Asia has many different climate types. Much of China has a Humid Subtropical climate. Another thing that effects the precipitation in East Asia is monsoon winds. Similar to South Asia, the summer monsoon brings heavy rain and the winter monsoon is very dry. More than two-thirds of China is covered in mountains and deserts. Arable land or land that can be farmed is an important resource. Only about 14 percent of China can be farmed. Many East Asian nations use terrace farming (pictured on right) by cutting “steps” into a mountain side and using the flat part of the “step” to grow rice.
