North and South Korea combined form a peninsula, which is a landform that is surrounded by water on three sides. Specifically, the Korean Peninsula is located in East Asia and extends southward from the mainland of the Asian continent, bordered by the Sea of Japan to the east, the Yellow Sea to the west, and the Korea Strait to the south.
The peninsula has a varied topography, including high mountains, deep valleys, and coastal plains. The highest peak in North Korea is Mount Paektu, which stands at 2,750 meters (9,022 feet) above sea level, while the highest peak in South Korea is Mount Hallasan, which rises to 1,950 meters (6,398 feet) above sea level.
