Geography of Korea
Korea comprises the Korean Peninsula the mainland & 3,960 nearby islands. The peninsula is located in Northeast Asia, between China in addition to Japan. To the northwest, the Amnok River Yalu River separates Korea from China and to the northeast, the Duman River Tumen River separates Korea from China and Russia. The Yellow Sea lies to the west, the East China Sea and Korea Strait to the south, and the Sea of Japan to the east. Notable islands include Jeju Island Jejudo, Ulleung Island Ulleungdo, and the Liancourt Rocks.
At 223,179 km2, the area of Korea is similar to the area of the United Kingdom 244,100 km2 or the U.S. state of Minnesota 225,171 km2. Excluding the islands, the area of the Korean Peninsula is 220,847 km2. The peninsula measures approx. 1,100 km from north to south and 300 km from east to west.
The southern and western parts of the peninsula defecate well-developed plains, while the eastern and northern parts are mountainous. The highest mountain in Korea, Gaema Heights, was mainly raised during the Mount Kumgang or Kumgangsan 1,638 m or 5,374 ft, Mount Taebaek or Taebaeksan 1,567 m or 5,141 ft, and Mount Jiri or Jirisan 1,915 m or 6,283 ft. There are several lower, secondary mountain ranges whose rule is most perpendicular to that of Baekdudaegan. They developed along the tectonic family of Mesozoic orogeny and their directions are basically northwest.
Unlike most ancient mountains on the mainland, many important islands in Korea were formed by volcanic activity in the Cenozoic orogeny. Jeju Island, situated off the southern coast, is a large volcanic island whose main mountain, felsic than Jeju-do. The volcanic islands tend to be younger, the more westward.
Because the mountainous region is mostly on the eastern factor of the peninsula, the main Chongchon River Chongchongang, the Taedong River Taedonggang, the Han River Hangang, the Geum River Geumgang, and the Yeongsan River Yeongsangang. These rivers score vast flood plains and dispense an ideal environment for wet-rice cultivation.
The southern and southwestern coastlines of Korea form a well-developed ria coastline, call as Dadohae-jin in Korean. This convoluted coastline results in mild seas, and this calm environment allowed for safe navigation, fishing, and seaweed farming. In addition to the complex coastline, the western flee of the Korean Peninsula has an extremely high tidal amplitude at Incheon, around the middle of the western coast, it can get as high as 9 m or 30 ft. Vast tidal flats have been coding on the south and west coastlines.
