Topography of South Korea

Seoraksan mountain in Gangwondo.

South Korea occupies the southern portion of the Korean Peninsula, which extends some 680 miles (1,100 km) from the Asian mainland. This mountainous peninsula is flanked by the Yellow Sea to the west, and the Sea of Japan (East Sea) to the east. Its southern tip lies on the Korea Straitand the East China Sea.

The country's total area is 38,622.57 square miles (100,032.00 km²).

South Korea can be divided into four general regions: an eastern region of high mountain ranges and narrow coastal plains; a western region of broad coastal plains, river basins, and rolling hills; a southwestern region of mountains and valleys; and a southeastern region dominated by the broad basin of the Nakdong River.

South Korea's terrain is mostly mountainous, most of which is not arable. Lowlands, located primarily in the west and southeast, constitute only 30% of the total land area.

About three thousand islands, mostly small and uninhabited, lie off the western and southern coasts of South Korea. Jeju-do is located about 100 kilometers (about 60 mi) off the southern coast of South Korea. It is the country's largest island, with an area of 1,845 square kilometres (712 sq mi). Jeju is also the site of South Korea's highest point: Hallasan, an extinct volcano, reaches 1,950 metres (6,398 ft) above sea level. The most eastern islands of South Korea include Ulleungdo and Dokdo, while Marado and Ieodo are the southernmost islands of South Korea.

Climate

Cheonggyecheon flowing through Seoul.

South Korea has a humid continental climate andhumid subtropical climate. and is affected by theEast Asian monsoon, with precipitation heavier in summer during a short rainy season called jangma(장마), and winters that can be bitterly cold. InSeoul, the average January temperature range is -7 °C to 1 °C (19 °F to 33 °F), and the average July temperature range is 22 °C to 29 °C (71 °F to 83 °F). Winter temperatures are higher along the southern coast and considerably lower in the mountainous interior. Rainfall is concentrated in the summer months of June through September. The southern coast is subject to late summer typhoons that bring strong winds and heavy rains. The average annual precipitation varies from 1,370 millimeters (54 inches) in Seoul to 1,470 millimeters (58 inches) in Busan. There are occasional typhoons that bring high winds and floods. The government is concerned of the impact of global warming on the natural disasters.

Environment

In the past, urban areas such as Seoul had minor problems associated with air pollution and water pollution. However, the Mayor of Seoul has been working hard to restore the flow of clean water in South Korea, by recovering the flow of Cheonggyecheon in central Seoul, for example. South Korea is a member of numerous international environmental organizations with specific regards to Antarctic-Environmental Protocol, Antarctic Treaty, Biodiversity, Climate Change, Desertification, Endangered Species, Environmental Modification, Hazardous Wastes, Law of the Sea, Marine Dumping, Nuclear Test Ban, Ozone Layer Protection, Ship Pollution (MARPOL 73/78), Tropical Timber 83, Tropical Timber 94, Wetlands, and Whaling.

The South Korean government's July 2008 decision to boost investment into renewable energy to reduce its reliance on foreign oil imports may provide a boost to conglomerates' solar plans. The Ministry of Knowledge and Economy said the country intends to spend 194.4 billion won ($193 million) on technologies and projects, including solar, wind and biofuels, in 2008r.
