Ask a few questions about physical geography in high school

First of all, to the west of him, there is a mountain in Jia**. The tall mountains block the water vapor from the Pacific Ocean, and the second is that its land area is not large, and the difference in the thermal properties of the sea and land is not obvious. There is also a plateau, with high altitude and relatively low temperature, and the difference in thermal properties between sea and land is not obvious.

Warm grass is formed.

Because its land area is not particularly large, the difference between the thermal properties of land and sea is not obvious, and the monsoon is not strong, its precipitation is not as much as that of the Asian monsoon climate, so it forms a grassland landscape.

First of all, make sure that this is an economic geography question. Then carefully analyze the figure of its processing and manufacturing added value is the lowest and other links with high added value, the middle part is determined to be labor-intensive, which can be linked to the actual electronic assembly, automobile assembly, garment processing and other industries, at both ends of the high added value there are developed countries to develop and develop markets, and the low value-added processing raw materials lack part of outsourcing to labor and resource-rich countries and regions for OEM, often these primary processing will bring many environmental problems to underdeveloped areas, This is the industrial transfer under economic globalization, and it is obvious from the figure that globalization is used in the whole activity to minimize production costs and maximize profits!

3 can be excluded first, followed by 4, hey, in fact, you shouldn't give the answer, let me guess!

Study hard!

Hey. Did you know that this diagram is called the smile curve? It means that the added value obtained by processing and manufacturing is very low, and only by independent research and development and sales can we improve the added value of our country!

And China is currently in the processing and manufacturing of the smile curve. In order to increase the added value, what we need to do is to vigorously develop and create.

So exclude. Again, this place is a capital-intensive industry, so the dominant factor cannot be labor-oriented, only electronic assembly factories and garment factories will lead to labor shortages. Any industry, no matter what, will have a shortage of resources to a certain extent.

It can be concluded from the fact that the added value of product design, technology research and development and marketing services is high, while the added value of processing and manufacturing is low.

The resource utilization rate is low, and product design, technology R&D and marketing services are the backbone of the industry, so it will not make profits fall.

There will be no labor shortage.

First, the production process of the product focuses on product design, technology research and development, sales and service, and does not pay much attention to processing and manufacturing (the added value of the ordinate can be seen), so there will naturally be no labor shortage. Second,.This sector of economic activity focuses on design and research, which means that it is a technology-intensive industry, so it is natural that there will be no problem of declining profits.

It can be seen from the added value of the product production link in the figure: the added value generated by product design and after-sales service is much higher than the added value generated by the intermediate link (processing and manufacturing), it can be seen that this is transnational production under the influence of globalization, this global production makes the resources between different countries be effectively allocated, developed countries use cheap labor in our developing countries for production, such as: Nike brand sneaker manufacturing, developed countries have product technology design and brand research and development, And China has cheap labor, so the developed countries have carried out the transfer of production, so that their profits have increased, so it is impossible for the manufacture of such products to have a decrease in profits, excluding 3

On the other hand, globalization has solved the problem of a small and expensive labour force in developed countries, which itself has a large number of labour in developing countries. So exclude 4

Make a list of the 25 questions together so that we can judge.

16.The answer is C

First, only relative heights can be estimated by visual inspection, but not absolute heights (because sea level cannot be seen), so a and d are wrong.

Secondly, the slope of the hillside on the ground side is characterized by a gentle rise and a steep descent, and the summit cannot be seen from the foot of the mountain (the light travels in a straight line), so it is impossible to estimate the relative height. Therefore, B is wrong.

The slope of the valley on the ground side is characterized by a steep rise and a gentle bottom, and the valley floor can be seen (also because the light travels in a straight line), so that the relative height can be estimated.

17.The answer is C

The geomorphological landscape of the northwestern region is the Hengduan Mountains (belonging to the folded mountains) in the western part of Sichuan Province, and the dominant factor is crustal movement.

16 b The relative height of the mountain can be estimated at the location.

c It is impossible to estimate the relative depth of the valley from a location - the bottom of the valley cannot be seen visually, and the relative depth of the valley cannot be estimated.

17 A Weathering.

The dominant factor of the landform landscape in Northwest China is the action of external forces, the movement of the earth's crust is naturally wrong due to the action of internal forces, and the climate of Northwest China is dry and water-deficient, and the dominant factors are weathering and wind erosion due to the action of external forces.

16 questions, choose BC. The relative height can be estimated visually, because the location is the ground, and the relative height is the height difference; The altitude can only be measured with the help of instruments and equipment.

Question 17, c. The northwest area in the map should be the upper left corner of the map, with obvious ups and downs, and showing regularity, which should be the folded mountain terrain caused by crustal movement.

What is the visual estimation method?I estimate that the altitude should be undetectable visually.

If the fold in the northwest of Chengdu is closer, it should be formed by fluvial sedimentation, and if it is farther away, it is formed by crustal movement.

b Location: Relative height of the mountain can be estimated.

c Crustal movements.

First of all, we must have a deep understanding of two key concepts: starting from the South Pole, the South Pole is a very special position on the earth's surface, it is one of the two points on the earth that has no direction (the other point is the North Pole), standing on the South Pole, the three directions of east, west and south are completely meaningless, and there is only one direction in the north; At the South Pole, the sun only rises and sets once a year, the sun never sets for half a year, it is all daytime, the sun revolves around the South Pole in a place not high from the horizon, and it never sets, also known as "polar day", there is no sun for half a year, it is all night, also known as "polar night".

Then learn what an ice sheet is: Ice sheets are not tied to geographical features, such as not necessarily at the top of a mountain, but their dome is generally centered on the highest point of a hill. The ice will move from its highest point towards the edges. This phenomenon is called ice divide.

Next, to answer your questions: the South Pole is covered with ice and snow all year round, with a thickness of 2,000 meters and an altitude of 3,800 meters; The climate is extremely harsh, with an average annual temperature of minus 49 degrees, an average temperature of minus 32 degrees in summer, an average temperature of minus 78 degrees in winter, a minimum temperature of minus 89 degrees, and an average annual precipitation of 3 mm. The South Pole is not the highest point of the Antarctic ice sheet, and the snow and ice covering the South Pole move at a rate of about 10 meters per year, so scientists have to re-mark the latest position of the South Pole once a year to set a benchmark.

Is it okay to explain it that way?

It is the highest point of the ice sheet, that is to say, it is ice, and the stability of the ice sheet is much worse than that of the continent, for example, in summer, it may become lower with the melting of some ice and snow, and it may increase in winter, especially this year, the global temperature has risen, and the ice sheet of Antarctica has been greatly affected

A is wrong.

South Pole: There are 3 poles at the southern tip of the earth, one of which is the geographical south pole at 90°, which is the intersection of the earth's axis of rotation and the earth's surface. The second is the south magnetic latitude of 90°, which is called the geomagnetic south pole.

The angle between the poles is 11°33' and the distance is about 1280 km. The third is the South Magnetic Pole located in the area of 140°E longitude and 65°S latitude, which moves at an annual speed of about 5-6 kilometers and becomes a magnetic pole drift. The distance between the geomagnetic south pole and the magnetic south pole is about 1350 km.

b。The highest point of the Antarctic continent is Vincennes Peak.

cd。The Antarctic wind is strong, it blows, it blows, the snow and ice move, the accumulation site will naturally move, and the height will naturally change.

The highest point of the Antarctic ice sheet is located at about 80°s, 77°E, while the latitude of the South Pole is 90°s, so a is false;

The highest point of the ice sheet is not the highest point of Antarctica, the highest point of the Antarctic continent is Mount Vincennes, with an altitude of 5140m, so b is wrong;

The highest point of the ice sheet is not set in stone and will move. For example, if only half a meter of snow falls at the current highest point, and it is very thick in another place, it may exceed the current highest point and become the current highest point. In addition, the ice sheet itself is not immobile.

So the C answer is correct;

As I have just analyzed, since it will move, the altitude will naturally change, such as the amount of precipitation, global warming, the movement of glaciers, and so on. So d answer is correct.

To answer these two questions, start with the question, "North Africa Five Countries Green Project" as far as I understand it should be a project such as afforestation, then look at the first question, according to the topic to observe the distribution of green projects, you can find that its distribution area is basically consistent with the Sahara Desert and its northern regions, and then think about the purpose of "green projects" should generally be afforestation, water conservation, prevention and control of land desertification, just corresponding. Therefore, the distribution factors of "green engineering" should be approximately equivalent to the distribution factors of deserts, and the most important thing is naturally the water conditions.

In the second question, the geographical distribution law mainly includes latitude zonality, longitude zonality, vertical zonality and non-zonality, which correspond to the four options of ABCD. In order to prevent desertification, the direction of green projects is determined by the distribution of deserts. The distribution of deserts is due to the distribution of desert zones in the natural zone, so it is the zonal law of latitude, so a is chosen.

Because I like geography very much, so as soon as I saw the geography topic, I was enthusiastic and wrote so much, hehe I haven't looked at geography much for a year after college, and I understand it from memory, and it may not be completely accurate, I hope it can help you.

The first is because of the amount of evaporation due to topography and regional differences, and the second is because only a is consistent with the direction of the project in the diagram.

The first is because green projects can only be distributed along the coast, and to the south is the Sahara Desert.

The second green project is an east-west extension, and the differentiation from the equator to the poles is an east-west extension and a north-south change.

B: These five countries in the south of the green project are basically tropical desert climate, the climate is arid all year round, precipitation is scarce, the desert is widely spread, and the desert is invaded in the north, while the north of the green project is close to the Mediterranean Sea, belongs to the Mediterranean climate, the winter is mild and rainy, the climate conditions are better, the economy is more developed, and the population is more dense, so there needs to be such a project to protect the north!

a: The regional differentiation from the equator to the poles extends in the east-west direction, which is determined by heat, and the higher the latitude, the lower the temperature; The regional differentiation from the coast to the inland is determined by water, so it is north-south, and the farther away from the ocean, the less water; The vertical regional differentiation of mountains is determined by heat, and the higher the altitude, the lower the temperature.

1.Let's put it in layman's terms: drought is when the sky does not rain and the air is dry, so it is counted in the atmosphere; Storm surge is when a typhoon blows seawater onto land, and although a typhoon is an atmospheric movement, it is the seawater that causes the disaster, so it is a matter of the hydrosphere.

2.It is certainly not wrong to write about sustainable development in terms of policy. As for controlling large cities, there will be many problems brought about by large cities, such as traffic congestion, high employment pressure, housing shortage, and intensified social contradictions, ......Therefore, the development of satellite towns (the construction of small towns around large cities to alleviate the problems mentioned above) is now advocated.

3.The Yellow River is second in terms of length, but its water volume is not large, the Pearl River and the Brahmaputra River are larger than him, and the analysis of the size of a river is dominant.

1.Drought is atmospheric, and the hydrosphere doesn't care about drought.

3. The second largest river is the Brahmaputra River, and the Yellow River is the second longest river.

First, the amount of flood water in spring is small.

II. 1Underlying Surface Factors:

The northwest inland of China is far away from the ocean, and there is rarely a surface with sufficient moisture, and deserts account for most of it. The specific heat capacity of water is larger than that of sand, soil, etc., so the temperature difference between day and night in the northwest inland of China is large in summer, the sky above the ocean is small, and the area close to the ocean is also small.

2.Radiation and Radiation Absorption of Clouds:

During the day, the northwest inland receives solar radiation energy, and the rent temperature rises sharply (here, because the specific heat is small, the temperature rises quickly); At night, there are fewer clouds in the sky, and the clouds can absorb the earth's long-wave radiation, which is an important factor in maintaining the earth's temperature from being too low, and the northwest inland has fewer clouds, and the ability to absorb long-wave radiation is weak, resulting in a sharp drop in temperature at night (this can be compared with the phenomenon on the moon: because there is no atmosphere on the moon, the temperature is very high during the day; At night there are no clouds to block the heat loss, and the temperature is as low as sub-freezing, resulting in a very large temperature difference between day and night).

3.Topography and environmental factors:

The special topography of three mountains and two basins belongs to the temperate continental climate.

Three pairs A cold wave is a cold snap.

Dry cold through sandstorms to cool down.

4b The bottom of the lake is widely distributed, and the water quality is good or not The bottom of the lake is excavated with mud.

c There are few big dances in the lake area, and the birds care about whether they have food or not.

d. The lake is affected by human activities, and the fish in Xiaopoyang Lake have been fished and cleaned.

a The beach area is large, and the water is shallow, and birds are easy to hunt and rest.
