The book is divided into two volumes, and they are edited by the Science Education Department of the Beijing Museum of Natural History. In the first volume we will learn about the earth, China, the Tibetan Plateau, the northwest region, the northeast region, and in the second volume we will see the North China, Central China, Southeast China, Southwest China, and the sea frontier.
About our planet.
In the 20th century, people saw the whole picture of the earth through satellites, and it was also verified that the earth is a sphere. The average radius of the Earth is 6,371 km, the maximum circumference is about 40,000 km, and the surface area is about 5100 million square kilometers, about 3 4 of the Earth's surface is covered by water, so it is a beautiful blue planet.
For our country, the complex and diverse climate makes us have different temperature zones. China has a vast territory, complex and diverse climate, and a significant monsoon climate.
The temperate continental climate is characterized by cold winters and hot summers, large annual and diurnal temperature ranges, and low rainfall. Mainly because these areas are too far from the sea to get enough moisture, such as Turpan in Xinjiang.
The temperate monsoon climate has four distinct seasons, with cold and dry winters and hot and rainy summers. When it's cold, the temperature will be below 0, and when it's hot, you will sweat profusely even if you wear half sleeves, such as the capital Beijing.
*The monsoon climate is characterized by high temperatures and rain in summer, and mild and rainy winters. "Mild" means that the temperature here in winter is generally above 0, and the river does not freeze, as in Shanghai.
The tropical monsoon climate is characterized by high temperatures throughout the year, with the average temperature in the coldest months often above 15. There is no obvious distinction between winter and summer, but there can be a clear dry season and rainy season, such as Sanya, Hainan.
The plateau mountain climate is formed by the influence of the high altitude of the Qinghai-Tibet Plateau, which is a natural barrier that blocks the cold air flow in the north and the humid air in the south, so the climate between the north and the south is very different, and the precipitation is mainly concentrated in the southern Himalayas. Later in the book, we will learn about the Chinese division.
Administrative division. China's land area of more than 9.6 million square kilometers is divided into 34 provincial-level administrative regions, including 23 provinces, 5 autonomous regions, 4 municipalities directly under the Central Government and 2 special administrative regions. Among them, the Xinjiang Uygur Autonomous Region has the largest area, the Inner Mongolia Autonomous Region has the widest longitude, the Guangdong Province has the largest permanent population, and Yunnan Province has the largest number of ethnic minorities.
Geographically regional.
In geographical research, China is divided into three natural regions according to landforms, monsoons and rainfalls, including the Qinghai-Tibet alpine region, the northwest arid and semi-arid region, and the eastern monsoon region. The Qinling-Huaihe River line is the dividing line between the north and south of China, so the monsoon area is divided into the northern region and the southern region.
Even so, these areas are still large, so they are subdivided according to a range of factors such as climate, soil, and organisms. For example, the northern region is divided into North China and Northeast China, and the southern region is divided into Central, Southwest and Southeast China. With the addition of China's maritime borders and islands, China is divided into eight distinct regions, which will be introduced in the book later.
The book is also in the form of comic dialogues and ** illustrations. It shows the characteristics of different regions, and in the book we can have a comprehensive understanding of our country's geographical knowledge and understand natural science. Popular science knowledge points. You can learn both geography and humanities, learn about the interesting living environment, and feel the good times given by nature.
