7. The dividing line between North America and South America: Panama Canal? The boundary between South America and Antarctica: Drake Strait

The dividing line between the four oceans?

(1) the Pacific Ocean and Arctic Ocean? The narrowest part of the Bering Strait starts from Cape Jakounyov in northeast Russia in the west, passes through Great Britain and Little Diomid in the Bering Strait, and reaches Cape Prince of Wales in Seward Peninsula at the western end of Alaska, USA. ?

② Pacific Ocean and Indian Ocean? It starts from the northern mouth of the Straits of Malacca in the north, along the west coast of Sumatra and the south coast of Java, passes through the Arafura Sea and the Tuozeus Strait, then along the east coast of Australia, and reaches the Antarctic continent via the southeast corner of Tasmania at east longitude 146. ?

(3) the Pacific Ocean and Atlantic Ocean? In the Drake Strait, it is roughly bounded by 67 west longitude passing through Cape Horn at the southern tip of South America. ?

(4) the Atlantic Ocean and the Arctic Ocean? It starts from the east entrance of Hudson Bay in the west, passes through davis strait, Danish Strait, Iceland-Faroe Threshold, Wavell-Thomson Ridge and markel-Frug Island in shetland islands, and reaches the first-line tasting point on the southwest coast of Norway. ? (5) the Atlantic Ocean and Indian Ocean? From the 20 east longitude line passing through Cape Aguilar at the southern tip of the African continent to the Antarctic continent.

Asia is a vast country. For the sake of understanding, Asia is divided into six regions: East Asia, Southeast Asia, South Asia, West Asia, Central Asia and North Asia. The natural environment and human activities in these areas have their own characteristics.

East Asia refers to the east of Asia. Include China, North Korea, South Korea, Mongolia and Japan. The area is about 1 1.7 million square kilometers. The population exceeds 65.438+0.7 billion. The terrain is high in the west and low in the east, and it is divided into four levels. The Qinghai-Tibet Plateau is known as the "roof of the world" in the southwest of China, with an average elevation of more than 4,000 meters. The southeast half is monsoon region, which belongs to temperate broad-leaved forest climate and subtropical forest climate; Northwest China belongs to continental temperate grassland with desert climate; Southwest is a mountainous plateau climate.

65438+ 10 May-June, the eastern coast was affected by typhoon. Coal, iron, petroleum, copper, antimony, tungsten, molybdenum, gold, magnesite and graphite are the most abundant mineral resources. East Asia is the origin of cultivated plants such as rice, yam, millet, buckwheat, soybean, ramie, tea, tung tree, lacquer tree, citrus, longan, litchi and ginseng. The rice produced accounts for more than 40% of the world's total rice production, tea accounts for more than 25% of the world's total rice production, and soybeans account for 20%. The output of cotton, peanuts, corn, sugarcane, sesame, rapeseed and silk occupies an important position in the world.
