The Korean Peninsula is a peninsula in East Asia. It extends southwards for about 684 miles (1,100 km) from the continental Asia into the Pacific Ocean and is surrounded by the Sea of Japan (East Sea) on the east, the East China Sea to the south, and the Yellow Sea to the west, the Korea Strait connecting the first two bodies of water.
Until the end of World War II, Korea was a single political entity whose territory roughly coincided with the Korean Peninsula. Since the cessation of the Korean War in 1953, the northern half has been occupied by North Korea, while the southern half has been occupied by South Korea. "Korean (or Korea) Peninsula", or "Korea", is sometimes used to refer to these two states together, though in South Korea, and in common discourse among many native English speakers, the word "Korea" refers specifically to the South. (This may be due to the perception of North Korea being a taboo subject in and of itself. Also, since North Koreans rarely travel outside of North Korea, the presumption is that any Korean one encounters is from the south).
The northern boundaries for the Korean Peninsula are commonly (and tacitly) taken to coincide with today's political borders between North Korea and her 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.
The peninsula is called Chosun Bando (Template:Hangul) in North Korea and Han Bando (Template:Hangul) in South Korea due to the different names for Korea.
Physical geography
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, with the highest mountains (including Baekdu Mountain which stands at 2,744 m) found in the north.
The peninsula has 8,460 kilometres of coastline, and the south and west coasts are highly irregular in particular; most of the 3,579 islands off the peninsula are found along the south and the west coasts.
Climate
The climate of the Korean Peninsula differs dramatically from north to south. The southern regions experience a relatively warm and wet climate similar to that of Japan, affected by warm ocean waters including the East Korea Warm Current. The northern regions experience a colder and to some extent more inland climate, in common with Manchuria. For example, the annual precipitation of the Yalu River valley (600 mm) is less than half of that on the south coast (1500 mm). [1] Likewise, there is a 20 °C difference in January temperature between the peninsula's southern and northern tips.
The entire peninsula, however, is affected by similar general patterns, including the East Asian monsoon in midsummer and the frequent incidence of typhoons in autumn. The majority of rainfall takes place during the summer months, with nearly half during the monsoon alone. Winters are cold, with January temperatures typically below freezing outside of Jeju Island. Winter precipitation is minimal, with little snow accumulation outside of mountainous areas.
Biology
Surveys of Korean flora have identified more than 3,000 species on the peninsula, of which more than 500 are endemic. The peninsula's floristic provinces are commonly divided between warm-temperate, temperate, and cold-temperate zones. The warm-temperate zone prevails over the southern coast and islands, including Jeju. It is typified by a large number of broad-leaved evergreens. The temperate zone covers the great majority of the peninsula, away from the southern coast and high mountains. It is dominated by the Korean pine and various broad-leaved deciduous trees. Cold-temperate vegetation is found along the peninsula's northern fringe and in the high mountains, including the upper reaches of Hallasan on Jeju. Evergreens in this area include larch and juniper. Much of this vegetation is shared with Manchuria.
Geology
The terrain of the Korean Peninsula is rumpled, covered with low mountains. Most rocks are of Precambrian origin, although isolated pockets of Paleozoic, Mesozoic, and Cenozoic rock can also be found.
There are no active volcanoes on the peninsula. However, Baekdu Mountain in the north and Hallasan in the south have crater lakes, indicating that they were active not long ago. Furthermore, hot springs indicative of low-level volcanic activity are widespread throughout the peninsula. Roughly two earthquakes are recorded per year, but few have any major impact.
