Landforms: Mountains and Plateaus.

East Asia stretches from the western provinces of China to the eastern coast of Japan. Mongolia, Taiwan, North Korea, and South Korea are the other countries in the region. East Asia includes high mountains, vast deserts, cold climates, and Pacific waters. The mostly rugged terrain was formed by the collision of tectonic plates. One result of these natural barriers was to limit people's movement and increase their isolation.
