Landforms

Over the next few days, I've had a few opportunities to experience the natural beauty of the country. South Korea is a peninsula, and is surrounded by the Yellow Sea and  the Sea of Japan. 70% of the country is covered by hills and mountains; most of the latter are located in the T'aebaeksan range. Mr. Paektusan, as it is called, is the highest mountain, reaching an elevation of 2,744 meters, which is approximately 9,002 feet.

Mountains are formed at convergent boundaries, where plates meet. The plates are forced together through convection, which in turn is caused by heating inside the earth. South Korea is located near the borders of the Eurasian and Philippine Plates. This location may increase the amount of plate activity.
