Ask for a geography master and a data emperor!! A puzzle!!

The linear velocity of rotation at the Earth's equator is 465 meter seconds.

Taking off from Beijing, it flew around the earth in the opposite direction for 3h20m, or about 93,000 meters.

For example, the main transport aircraft Boeing 737 300 400 500 700 800, and Airbus 319 320 321 basically cruise at a speed of 700km h and 1000km h, flying 3h20m, about 330000 meters.

This distance is definitely too short, it is impossible to fly to Amsterdam, but you have to pay attention to the difference between Beijing and Amsterdam 9 time zones, the time difference is 9 hours, and the stock is right, when you come, you have to subtract 9 hours from the retrograde, and you have to add 9 hours when you will go forward, so it's almost the same.

Flight KL898 flew from Beijing (116°E) to Amsterdam (4°E) for 3 hours and 20 minutes, that is, the Earth rotated from west to east for 3 hours and 20 minutes (3 hours and 20 minutes * 15° hours = 50°) - the actual flight of flight KL898: 116-4-50 = 62°, which is equivalent to the distance of 4 time zones (about one-sixth of the Earth).

Flight KL3811 flew east from Amsterdam to Beijing along the same route, taking 16 hours and 45 minutes, that is, the earth rotated from west to east for 16 hours and 45 minutes (16 hours and 45 minutes * 15° hours 251°) - the actual flight of flight KL3811 is 116-4 + 251 = 365 °, which is equivalent to more than one circle around the earth.

The first question A is located at the junction of the subduction of the oceanic plate to the continental plate, which is the boundary of plate extinction and should be a trench.

Ridges are the boundaries of plate growth.

Barriers and grabens are tectonic landforms on the surface, not seabed terrain.

In the second question, the example in the textbook is that the Eurasian plate collides with the Pacific plate, and the land plate is on the west side of the ocean plate and the east side of the oceanic plate, which is in the opposite direction from the figure in the figure. The same goes for the African plate and the Indian Ocean plate. The Eurasian and American plates are both terrestrial plates.

The ground is concave.

ABCD 4 options, only B and D are concave. Note that A is below sea level, so the first question can only be B

Note that the diagram shows the continental and oceanic plates. Of the 4 options, only B and C match.

In the figure, the oceanic plate subducts to the land, which is the extinction boundary, and c is the expansion boundary.

Therefore, the second question is also b

What I am best at is the knowledge of geography, and if you show the questions, you will definitely be given a satisfactory answer.

Let's take flight KL898 first.

The arrival time of the flight is 15:15 local time. It can be converted to Beijing time, that is, 22:15 (because Amsterdam is located in the East 1st District, and China is located in the East 8th District), and it was 11:55 when taking off from Beijing, so the flight flew for 11 hours.

Then count the KL3811 flight:

It was 14 the next day when I arrived in Beijing; 10.It can be converted to the local time of Amsterdam, which is 7; 10.So the flight took 9 hours and 45 minutes.

Therefore, it can be seen that in fact, there is not much difference. So why is there a little difference in the time of the round-trip flight, mainly because the round-trip flight route may be different, and the influence of the wind. There is the influence of a tailwind and a headwind!!

Criticism is welcome!!

Amsterdam is the capital of the Netherlands, and is located in the 1st district of the east according to its location, west of Beijing, a difference of 7 hours. When the plane arrived in Amsterdam from Beijing, it was 15:15 local time on February 28, and Beijing time was 22:00 at this time

15。The actual flight of the aircraft is 22:15.

When flying back to Beijing from Amsterdam, the Netherlands, the arrival time in Beijing is 14:10, and the time in Amsterdam is 07:10. The actual flight time of the plane is 07:10 the day before) 9h45m.

When we calculate the time of flight of the aircraft, we should calculate it by the time difference in the same place.

There is a 7-hour time difference between the Netherlands and China (winter) at 11:55 Beijing time and 15:15 local time (22:00 Beijing time).

15), the total time is 10 hours and 20 minutes, and the arrival time is 14:25 at 21:25 local time (3:25 Beijing time the next day) when returning from the Netherlands

10 minutes, total time 10 hours 45 minutes.

I haven't done the math carefully, and if you don't do well in the transfer, you won't understand it if you tell you. First of all, the plane flies from Beijing to Amsterdam is using the inferior arc positioning method, which means that it flies less, flying from low latitude to high latitude, affected by the earth's rotation deflection force, with Beijing as the origin, Amsterdam is in the northwest direction of China, so it goes less; Taking Amsterdam as the origin in the positioning, Beijing is in the southeast of Amsterdam, so it is a lot of walking, at the beginning it is to go to the eastern hemisphere, and when you come back, you will go to the western hemisphere, which is the question of how much longitude you cross, you can understand it by looking at the map. If you don't understand, you can continue to ask me!

I went, and when I was in high school, I was most annoyed by this kind of question

The first question is actually you can look at your atlas, which has detailed maps on it.

The same is true for the second question.

There are many topics in geography that you can understand by looking at the atlas, and you don't need to force them to explain.

The first question is also explained, and it can be seen at a glance that the upward arch must be the continent and the continental plate.

The second question, then I have to read the book, it has been too long, and I am not impressed.

1. The collision of continental plates with continental plates forms mountains [the arrow refers to the collision and extrusion of plates].

2. The Alps are mountains formed by the collision of continental plates and continental plates [Eurasian plate and African plate].

Look at the picture, the continent is flat high, and if it's a continent and an oceanic plate, it's a collision of one high and one low.

I think it's better to start with the basics like textbooks and memorize the basics that you should memorize.

Of course, the map has to memorize a lot of key locations, such as mountains, rivers, the topography of major cities, and so on. It is also necessary to understand and keep in mind the more common places.

Geography is a very scientific subject in the liberal arts, not only to memorize things but also to learn how to analyze and apply them, such as counting those times or something. If you want to catch up, you have to come step by step, master the basic knowledge, and then improve by doing questions. Memorizing maps is also essential.

1.Find a good reference book and go through the textbook according to the body of knowledge.

2.You should have a good atlas and try to form figures with the knowledge that can be written down with diagrams.

3.Finally, I have to get the college entrance examination questions and mock questions in recent years. (It's not about memorizing, it's about really figuring it out).

I'm also going to take the college entrance examination, and I've scored 16 points in geography, and now geography can sometimes take the first place in our class.

Geography is the three major blocks, physical geography, human geography, and regional geography.

Physical geography is the most important, running through the main line of geography learning, the content is difficult, are the focus, which determines whether you can open the gap with others, often people who do not learn physical geography well have no confidence to learn. It is impossible to learn geography quickly, and there are many knowledge points and it is very complicated.

Don't be afraid, listen carefully, it will change!

Regional geography is the basis for determining you, I don't know what to do, so you have to look at the map more. The economy is strong, distinctive, large, and so on. You can memorize it first, American, Indian and the like. Don't be fast.

The best thing to get points is human geography, just memorize more and remember more, it is recommended that you pick up geography from here is complementary to each other, and it is difficult to forget it.

Remember, you have a picture in your heart, don't die reading, do more questions.

Not at all, and as long as you pass, you can only memorize the knowledge points in the book. Enough is enough. When I took the college entrance examination, I got the first score in the city, and in my opinion, books are the foundation, and all the rules and regulations are ** and the knowledge of books.

Keep these in mind, there are no shortcuts.

If you have memorized the basic knowledge points but still do not do well in the test, it is that there is something wrong with the way you do the questions. That's when we think about combing knowledge. Regarding sorting out knowledge, a few people upstairs answered almost the same.

People pay special attention to what they are interested in, and they learn the fastest, "interest is their best teacher", you have to experience the fun of learning geography in the process. I have two suggestions here, first, find a way to experience the fun of learning in the process; Second, if you still don't think you can do it, look at the first one.

Question 1 is selected b

Question 2 Option C In the first question, the A in Figure A is located in the Northern Hemisphere, and the direction of rotation is counterclockwise, so it is on the morning line, in the early morning; Figure B is the Southern Hemisphere, and the direction of rotation is clockwise, so B is on the dusk line, at dusk; In Figure C, c is located in the Northern Hemisphere, and the direction of rotation is also counterclockwise, and on the morning line, it is early morning; The middle D of Tuding is located on the morning line, which is early in the morning.

In the second question, map A is the summer solstice in the northern hemisphere, map B is the summer solstice in the southern hemisphere, and map C and map D are both spring or autumn equinoxes, so option A is correct; D o'clock is on the morning line, so local time is 6 o'clock; The angular velocity of rotation in A, B, C, and D is 15 degrees per hour, and the linear velocity of the north and south poles is 0. The direction of motion in option c is from east to west.

According to the figure, it can be seen that Figure B is a top view of the South Pole, where each point in the South Pole moves clockwise around the South Pole, and point B will enter the night along the direction of rotation, so it is at dusk. Therefore, the answer to the previous question should be B. Question 2:

The morning and dusk lines in Figure C and Figure D both pass through the poles, so they are both vernal or autumn equinox days; In the Ding diagram, point d will enter the daylight and be on the morning line at 6 o'clock local time in the equinox, so the local time at point d is 6 o'clock local time. The direction of rotation of the earth is from west to east, so the direction of rotation of the morning and dusk line on the ground should be opposite to the direction of rotation, so the statement of c is incorrect, so option c is chosen; The four points of ABCD are not at the poles, so the angular velocity of the rotation is the same, while the two points of ns are at the two poles, and the linear velocity of the rotation is 0 (i.e., equal).

b c

Judging method: the east-west time zone is the ** meridian of the 0 time zone with the prime meridian, that is, the 0 degree meridian, each time zone is 15 degrees, from the 0 time zone to the east is the east time zone from 1 to 12 time zones, and to the west is the west 1 to 12 time zones.

From night to day, it is the morning line, and vice versa.

1, b (on the dusk line), 2, c (from east to west).

The answer is b c

Do you have a globe? If you have one, you can imitate it with a globe.

The Arctic Circle of Figure A is the polar day, which means that it is the summer solstice, and the day and night are equal to the night in Figure C, so it is either the spring equinox or the autumn equinox. You can understand that.
