Chapter VI Asia, the continent where we live.

Section 1 Natural environment

First, the largest continent in the world.

1. Ball position: Most of Asia is located in the Eastern Hemisphere and the Northern Hemisphere.

2. Close to the ocean: the Arctic Ocean in northern Asia, the Pacific Ocean in the east and the Indian Ocean in the south.

3. Continent and dividing line: Northwest Asia is bounded by Ural Mountain, ural river, Caspian Sea, Caucasus Mountain, Black Sea, Turkish Strait and Europe; Southwest Asia is bounded by Suez Canal and Africa; South faces Oceania across the sea; The northeast faces North America across the Bering Strait.

4. Asia is the largest continent in the world, with the widest latitude and the farthest distance from east to west.

5. Asia Division: Asia is divided into East Asia, Southeast Asia, South Asia, West Asia, Central Asia and North Asia according to geographical location.

China is located in East Asia, which also includes North Korea, South Korea, Japan and Mongolia.

7. China borders North Asia to the north, West Asia and Central Asia to the west, South Asia to the southwest and Southeast Asia to the south.

Second, topography and rivers.

1, Asian topographic features: the ground is undulating, high in the middle and low around; The terrain is complex and diverse, mainly plateaus and mountains.

2. Main topographic areas: The Qinghai-Tibet Plateau is located in central Asia, with an altitude of over 3,000 meters, and some areas are higher than 5,000 meters, which is called the "roof of the world"; The western Siberian plain ~ ~ is located in the north of Asia, with an altitude of 0~200 meters, and is the largest plain in Asia. North China Plain ~ ~ is distributed in eastern Asia, with an altitude of 0~200 meters; Indus plain ~ ~ is distributed in southern Asia, with an altitude of 0~200 meters; Deccan Plateau is distributed in southern Asia, with an altitude of 200~ 1000 meters. Iranian plateau ~ ~ is distributed in western Asia, with an altitude of 1000~3000 meters; The mountains in central Siberia are distributed in northern Asia.

3. Major rivers and oceans: ob river, Yenisei River and Lena River flow into the Arctic Ocean; The Yellow River, the Yangtze River and the Meigong River flow into the Pacific Ocean, and the Ganges River flows into the Indian Ocean.

4. Distribution characteristics of rivers: Most rivers originate from the mountains and plateaus in the middle and flow radially to the surrounding oceans. The reason is that the terrain in Asia is high in the middle and low around.

5. Lake: Caspian Sea ~ ~ The largest lake in the world, saltwater lake; Lake Baikal ~ ~ the deepest freshwater lake with the largest storage capacity in the world; Dead sea ~ ~ the lowest point of the world land.

Third, the complex climate.

1. Climate characteristics: complex and diverse, with remarkable monsoon climate and the widest continental climate distribution.

2. Climate influencing factors: latitude factors ~ ~ Asia spans tropical, temperate and cold zones, and the higher the latitude, the lower the temperature; Land and sea factors ~ ~ Asia is close to the ocean on three sides, with more precipitation in the east and south and less precipitation in the central and western regions; Topographic factors ~ ~ Qinghai-Tibet Plateau and Pamirs have high altitude, resulting in plateau mountain climate.

3. Main climate types: tropical rain forest climate, tropical monsoon climate, subtropical monsoon climate, temperate monsoon climate, temperate continental climate, tropical subtropical desert climate, Mediterranean climate, plateau mountain climate and cold zone climate.

4. temperate continental climate: it is the most widely distributed climate type in Asia, covering central and western Asia. Its climate is characterized by long and cold winters, short and warm summers, and scarce precipitation throughout the year.

5. Monsoon climate: It is mainly distributed in the east and south of Asia, and is characterized by large seasonal changes in wind direction and seasonal changes in precipitation throughout the year. The disadvantage is that it is prone to droughts and floods.

6. Characteristics of climate distribution in Africa: with the equator as the center, the climate types are symmetrically distributed in the north and south; The tropical climate is dominant, and the tropical rain forest and savanna climate are widely distributed.

Section 2 Human environment

First, the most populous continent.

In 2000, the total population of the world was 6.055 billion, and the population of Asia was about 3.68 billion, accounting for 665.438+0% of the total population, making it the most populous continent.

5. The net population of the world is 6.055 billion×1.3% = 78710,000. The net population of Asia is 3.68 billion×1.4% = 51.52 million.

6. Asia has a large population, which puts great pressure on resources and environment.

Second, diverse regional culture.

1. There are about 1000 ethnic groups in Asia, accounting for about half of the total ethnic groups in the world. Among them, the Han nationality is the most populous nation in the world.

2. The three cradles of human civilization in Asia: the Yellow River and the middle and lower reaches of the Yangtze River; Indus valley area; Mesopotamia Plain (two river basins). Reason: Suitable for temperate (or tropical) climate; Abundant water sources; Fertile land.

3. Ethnic groups in different regions show different cultural and artistic styles and different national customs in terms of architecture, costumes, music and dance, etiquette, etc.

5. Every country has its own unique cultural customs, and understanding and respecting the cultures of other regions is the basis for realizing friendly exchanges with other countries. Therefore, before going abroad, people should understand the customs of the country they are going to and respect their cultural differences.

Second, differences in economic development.

1, Asia's economic development is unbalanced; A few countries belong to developed countries, and most countries belong to developing countries.

2. Countries with per capita GNP exceeding 10000 USD: Japan, Israel and Singapore; Countries with per capita GNP below $500 are: Vietnam, Mongolia, Nepal, Bangladesh and India; Japan's per capita GNP is about 145 times that of Nepal.

Russian industry is dominated by heavy industry, and the development of light industry is slow, and the main industrial areas are concentrated in Europe. In contrast, the Asian part is relatively weak, resulting in uneven distribution of light and heavy industries. The characteristics of industry are closely related to its resource conditions. Russia's oil, natural gas, iron ore and other resources are rich and widely distributed, which is conducive to the development of heavy industry.

Third, developed transportation.

Eurasian land bridge

Some railway networks in Russia and Europe are obviously dense, while some railway networks in Asia are relatively single. Trans-siberian railway, built in the southern mountainous area, is more convenient for economic development, mainly considering the climatic reasons and its proximity to neighboring countries.

Passenger transport is mainly by railway and highway; Goods are transported by rail and pipeline, among which pipeline transportation accounts for the largest proportion.

Moscow is the largest city and St. Petersburg is the second largest city.
