The geography of Korea consists of two main regions: North Korea and South Korea. The Korean Peninsula is bordered by the Yellow Sea to the west, the Sea of Japan to the east, and the Korean Strait to the south. The landscape features mountains, valleys, and coastal plains, with the Taebaek Mountains running down the eastern side. North Korea is known for its rugged terrain, while South Korea has a mix of urban areas and natural parks. Major rivers, such as the Han River in the south, play a crucial role in agriculture and transportation. The climate varies from temperate to continental, influencing the region's biodiversity.
