North and South Korea, when combined, predominantly showcase a mountainous landform characterized by rugged terrain and high elevations. The Korean Peninsula is essentially a mountainous region, with a series of mountain ranges such as the Taebaek Mountains running down the eastern side and the Sobaek Mountains in the center.
This mountainous landscape is interspersed with valleys and plateaus, giving rise to a diverse range of climate conditions and ecosystems. The highest peak in the region is Mount Paektu, which stands at 2,744 meters (9,003 feet) and holds significant cultural importance in both North and South Korean history.
In addition to the mountains, the peninsula also features coastal plains and river valleys, especially on the western and southern coasts. These plains are crucial for agriculture and urban development, providing fertile land that contrasts with the surrounding highlands. Therefore, the overall landform of North and South Korea can be described as a mix of rugged mountains, rolling hills, and river valleys, shaped by geological processes over millions of years.
