Section 1 "Land of Sunrise"-Asia-Asia

Asia: the land of sunrise in the east; Europa: the place of sunset in the west.

Why is Asia the largest continent?

1) the largest area 2) the widest latitude 3) the longest distance from east to west.

1. Geographical location of Asia:

(1) Asia is located in the Eastern Hemisphere, bordering the Pacific Ocean in the east, the Indian Ocean in the south, the Arctic Ocean in the north and the Mediterranean Sea in the west. Asia spans about 90 degrees latitude and 164 degrees longitude.

(2) The western part of Asia is bounded by the Urals, the Turkish Strait and Europe, the southwestern part is connected with Africa through the Suez Canal, and the eastern part faces North America through the Bering Strait.

(3) Asia covers an area of 4.4 million square kilometers, which is 4.8 times that of Oceania and is the largest continent in the world.

The seven continents are Asia, Africa, North and South America, Antarctica and Europe.

2. Asia's complex and diverse natural environment:

(1) With an average elevation of 950m, Asia is the continent with the biggest ups and downs and the smallest disparity in the world. It has the "roof of the world"-the Qinghai-Tibet Plateau, the vast lowland-the West Siberian Plain, the "top of the world"-Mount Everest, and the lowest point in the world-the Dead Sea.

(2) Mount Everest (8844 meters above sea level) and the Dead Sea (-400 meters above sea level).

③ Western Siberia Plain, the largest plain in Asia.

(4) The topography of Asia is dominated by plateaus and mountains, with the central part towering and the surrounding areas low. Affected by the terrain, the river flows radially.

3. Climate in Asia:

(1) Asia is dominated by temperate continental climate with typical monsoon climate (temperate monsoon climate, subtropical monsoon climate and tropical monsoon climate). (Figure 7.6 on page 6 of the textbook)

(2) Asia is influenced by topographic factors, with more precipitation near the ocean and less inland.

(3) Southeast Asia is the largest rice producer in the world, which is closely related to the summer monsoon.

(4) The influence of the change of prevailing wind direction in Shanghai in winter and summer on the climate:

Northwest wind prevails in winter, and the climate is cold and dry.

Southeast winds prevail in summer, and the climate is hot and rainy.

4. Division of Asia: Asia is divided into East Asia, Southeast Asia, South Asia, Central Asia, West Asia and North Asia (the Asian part of Russia) according to geographical location, natural and human geographical elements.

5. Population of Asia: It is the most populous continent in the world, with a total of over 3.5 billion, accounting for about 60.5% of the world's total population. Among the 1 0 countries with a population of more than 100 million in the world, there are 6 countries in Asia (East Asia-China, Japanese; South Asia-India, Pakistan, Bangladesh; Southeast Asia-Indonesia).

6. The huge population has intensified the pressure on the natural environment and natural resources, which has become a heavy social and economic burden for some Asian countries. Controlling population and improving population quality are issues that many countries in Asia must attach importance to.

Main agricultural belt

Reasons for the formation of agricultural belt

Dairy belt is located in the north, with a cold and humid climate, which is suitable for pasture growth. Moreover, this is the manufacturing belt of the United States, with dense urban and population distribution, so animal husbandry is very developed.

Corn belt belongs to temperate zone, with low and flat terrain, fertile soil and high temperature in spring and summer, which is suitable for corn growth.

The cotton belt was originally a cotton belt, but due to the decline of soil fertility and other reasons, cotton planting has declined. Now it has become a variety of crop areas dominated by animal husbandry.

Wheat belt has low terrain, good soil quality, cold and long winter, which is suitable for the growth of wheat with strong cold tolerance. The Mississippi River provides good conditions for irrigation.

Animal husbandry irrigation belt The terrain here is plateau and high mountain, with large relief and little precipitation, which is suitable for developing animal husbandry and irrigated agriculture.

The subtropical crop belt is located along the Gulf of Mexico, with subtropical monsoon climate, high temperature and rainy all the year round, which is suitable for the growth of subtropical crops.
