Ask the master to solve a few high school geography questions

17.A is a fault, (the rock layer arches upwards as an anticline), so B is an anticline, and C is an anticline. Select B18Because the anticline is a good oil storage structure, choose B

19.Choose C

20.The North China Plain is a typical alluvial plain. The main rivers shaping the North China Plain are the Yellow River, the Huai River and the Hai River, so it is also called the Huang-Huai-Hai Plain.

So it is formed by the deposition of flowing water. Karst landforms are formed by wind erosion. The ravines of the Loess Plateau are formed by the erosion of flowing water due to the scarcity of vegetation.

The Great Rift Valley was formed by geological processes. Pick D

ps: I'm sorry... The... 21 questions·· Due to the prevalence of crustal uplift, the wind is difficult to reach the leeward slope, resulting in drought and little rain on the leeward slope, so the trees die, and the destruction of human causes, so the root cause is the rise of the earth's crust. (I'm sorry if I'm wrong...) I'm too careless... Sorry·· ）

17b A is a fault, B is an anticline, (the bottom layer arches upward) C is an anticline.

The 18b anticline is a good oil and gas storage structure.

19c Water flow slows down sediment formation.

20d The North China Plain, also known as the Huang-Huai-Hai Plain, was formed by the impact of the Yellow River, Haihe and Huai River.

21a The increase in land height from left to right in the three maps is due to the rise of the earth's crust and the leeward slope in the east, so by the time of the third map, a desert had been formed.

The changes in the natural zone caused by the 22-day elevation of the terrain are interrelated and mutually influential, so they are holistic.

17 is b, because A is the intersection of two different terrains; The stratum is facing away from ground B; Because the formation is bent towards C.

18 is b, because the anticline is a good oil storage structure.

19 is c, and the deposition of flowing water is the cause of the estuarine delta.

20 is d, because the North China Plain is a typical alluvial plain.

21 is B because B has the greatest environmental impact.

22 is d.

Don't talk about anything else, the last question c

10 solution: Because it is from the spring equinox to the summer solstice, Qi Tan thinks that no matter whether the O point is the South Pole or the North Pole, the Tan Tsai rotten MN is far away from the O point, so choose C.

11 Solution: Because m

The dot is the morning and dusk line.

The upper latitude is the highest leakage point, and Mn is the dusk line, that is, m, o, and the sun are on the same line, so the sun is due north of the m point.

1. Madrid and Santiago are cities located in the northern hemisphere, and Rio de Janeiro in the southern hemisphere. From the conditions given in the title, it can be seen that this is the summer half of the northern hemisphere and the winter half of the southern hemisphere, so it is not suitable for Antarctic scientific research, Madrid has long days and short nights, and Santiago has a Mediterranean climate, so the summer is hot and dry. Rio de Janeiro has a savannah climate with little precipitation in winter, so option D is correct.

2. D It is impossible to determine whether the northern hemisphere is a summer or winter half, so it is discussed separately in two cases. Finally, from the solar altitude angle, we can know that the solar altitude angle of m may be 5 degrees or 30 degrees.

3. B can't tell whether the northern hemisphere is a summer or winter half a year at this time, and option A has two cases, wrong. At this time, London is still in the second half of the night, there is no sun, and option C is wrong.

1.Option D, the polar and subtropical regions are controlled by high pressure, and downdrafts prevail. So A, C is wrong.

The subpolar regions and the equator are controlled by low pressure and prevail updrafts, but the higher equatorial temperatures are more conducive to the upward airflow. So B is wrong, D is correct.

2.The windless zone includes the equatorial windless zone, the subtropical windless zone, and the polar windless zone.

1d The equatorial region is said to have a high temperature and rising airflow, which is an important part of the atmospheric circulation.

2 The equatorial low-pressure zone, also known as the equatorial windless zone, prevails with updrafts and no prevailing winds. the subtropical high-pressure zone, where downdrafts prevail; The subpolar low-pressure zone prevails with updrafts.

As long as you think that Beijing is the capital, Jinan is the provincial capital, and Beijing is higher in terms of level, then naturally Beijing has a greater influence on the surrounding areas and even the whole country. This is purely a theoretical geography problem, as long as you follow the theory memorized in the textbook, you will not be wrong.

A provincial capital city has been formed for a long time, so the service functions that the city should be able to provide should be basically complete, but there are differences in service quality.

The higher the level of the city, the higher the level of services provided and the greater the scope of services.

b a a,,, why there are fewer drawings.

The first question is to see that there is no Tropic of Cancer, only Europe.

The second question, there is no picture, I can only use the elimination method, the day length in Beijing is shorter than that in Guangzhou, which means that it should be in winter.

Season. c The water in the northern Indian Ocean flows in a clockwise direction, indicating that the Indian Ocean is a southwest monsoon, i.e.

Summertime. d The Tarim River is in the season of abundant water, and the Tarim River is an inland river, with little precipitation and runoff in the basin.

It mainly depends on the melting water of alpine ice and snow, so it should be summer. As for b the earth moves near aphelion, summer.

Season, there is no need to talk about it.

Third, it can be seen from the way that neither the north and south poles are polar day or polar night, but the global day and night are equinox, which should be.

At the equinox, b Arbor Day in our country is coming soon, Arbor Day, 12 March. It's over. c m point.

The length of the day and the short of the night, the m point is now the equinox of day and night. d At this time, the direct point of the sun passes from the northern hemisphere to the southern hemisphere.

Because it is not specific what day it is, it cannot be said in this way.

10 questions, choose Europe, of which the southern part of Asia is obviously in the tropics, the American state of Hawaii in North America is in the tropics, and the three archipelagos of Oceania are in the tropics.

Question 1, this kind of question does not need to look at the picture, it is the second half of the Northern Hemisphere, and A is the opposite.

Question 2, A, Arbor Day has to be postponed.

Chip production is a technology-oriented enterprise.

Because chip production is a technology-oriented enterprise, the quality of workers is high, China's labor force is rich and cheap, but the quality of workers is not high, for the transfer of such enterprises, is to look at China's huge market (many Chinese, consumer demand).

This is common sense in the UK, just remember it.

Both cities are located at transportation hubs.

DBC (the highest level of industrialization in the United States, not sure) B

Manufacturing outsourcing is actually to reduce production costs and process some aspects of products abroad, such as Apple in the United States to contract the production of Apple machines to Foxconn in China. a, because manufacturing is placed abroad, which does not increase employment opportunities in the country; b. False, not to strengthen the link between R&D and production; c Correct, the purpose of the enterprise is to make a profit (remember), so the choice of most enterprises is to reduce production costs as much as possible and obtain more profits; The origin is placed abroad, which is conducive to expanding the international market of products. dNot necessarily, some product outsourcing may be to be close to the origin of raw materials and reduce the cost of raw material transportation; But some are taking advantage of cheap labor abroad; Taking a step back, even if you reduce the cost of transporting raw materials, you will increase the cost of transporting the product.

a: I can't see the data clearly. But I can tell you: the contour lines on both sides of the river have equal values; Rivers flow from high to low.

So just count the value of the third contour line on the left according to the data. Subtracting 72 meters from this value is the highest possible elevation of the lake's water level. b False, due to the erosion of flowing water, the mud and rocks under the waterfall are gradually carried away by the erosion of the water, and the position of the waterfall will be pushed upstream.

C false, China's dike-pond agriculture is mainly in the Pearl River Delta, which has greater requirements for terrain and moisture. The area shown in the picture is relatively high, which is not conducive to the development of dike-pond agriculture. D correct q should be mountainous, suitable for the development of forestry.

According to the concept, if the inflow is exactly equal to the outflow, then the water surplus rate is 1. That is to say:

If the value is greater than 1, the inflow is greater than the outflow, and the water level rises; If the value is less than 1, the outflow is greater than the inflow, and the water level drops. According to the figure, it can be found that from about September until March of the following year, the amount of water has been more inflow than outflow, that is, the water level has been rising; From March to September, the water level has been dropping, so of course it is the highest water level in March.

Feel free to ask.
