Green Mountains of the Korean Peninsula38.3N 127.4E
The Korean Peninsula is a peninsula in East Asia that extends southwards for about 684 miles (1,100 km) from continental Asia into the Pacific Ocean. It is surrounded by the Sea of Japan (also called the East Sea) on the east, the East China Sea to the south, and the Yellow Sea to the west. The first two bodies of water are connected by the Korea Strait.
The northern boundaries for the Korean Peninsula are commonly taken to coincide with today’s political borders between North Korea and its northern neighbors, China (1,416 km along the provinces of Jilin and Liaoning) and Russia (19 km).
These borders are formed naturally by the rivers Yalu/Amnok and Tumen/Tuman/Duman. Taking this definition, the Korean Peninsula (including its islands) has an area of 220,847 km2 (85,270 sq mi).
Mountains cover 70 percent of the Korean Peninsula and arable plains are generally small and far in between the successive mountain ranges. The peninsula becomes more mountainous towards the north and the east, visible here by the dark green color of vegetation on the peaks.
