Geography Questions: Ask for advice Geography questions, ask the great god to answer

1. A summer solstice, B autumn equinox, C winter solstice, D spring equinox.

2. Point C turns the fastest, because it is winter in the Northern Hemisphere, and the Earth is closer to the Sun (according to the physical Kepler formula, close to the focus and fast).

3. The Tropic of Cancer and the area north of the Tropic of Capricorn.

4. Counterclockwise.

5. Winter solstice (December 22), autumn equinox (September 23), winter solstice (December 22), c

By the way, upstairs misunderstanding)

1.The solar terms shown at 4 points in the figure: a b c d 2

The Earth's revolution at point b in the diagram is faster because the radius is 3When the Earth is at point a, the largest region of the year when the global midday sun is high is the equator

4.Draw the direction of the Earth's revolution in the diagram. (Drawn on the track) is pretty much downward.

5.The day is shortest and the night is longest in the Northern Hemisphere on December 22, and the polar night begins in the Arctic Circle on December 22

The time of the highest noon solar height in the area south of the Tropic of Capricorn is December 22, when the direction of movement of the direct point of the sun turns from south to north.

The time from south to north is d fill in the code) The diagram and the title do not match???

1. A summer solstice, B autumn equinox, C winter solstice, D spring equinox.

2. A is the fastest turn, because the time is the same, and A is the longest.

3. The Tropic of Cancer and the area north of the Tropic of Capricorn.

4. From A to B, B to C, C to D, D to A

December 22, December 22, December 22, c

When the global date range is equally divided, the 0 degree meridian is exactly 0 o'clock, and the corresponding point in the East 8 region is 8 o'clock, 8:00-4:50 = 3:10

Therefore, choose B for question 14Milan is in the south of Paris, and at this time it is in the winter half, and the days are longer, so the apex becomes higher and the opening is larger.

Milan is on the east side of Paris, so the local time at 12 o'clock of course comes earlier, and the axis of symmetry shifts to the left.

Therefore, D is selected for question 15

The information in this question can be copied and seen to be plagiarized.

The circulation in the valley area, so no matter how you look at the isotherms, it will not be flat, 2 direct pass (there is a temperature difference before there is air flow, the isotherms are flat, what kind of wind does it blow, if it is only in the air, it may be flat, but the isotherms are connected to the ground!) There are 2 situations in the valley, first of all, during the day, the wind direction blows from the valley bottom to the top of the mountain so 1 is correct, the high pressure blows the low pressure so 4 is correct, and 3 should go down. Looking at the night, the wind direction blows from the top of the mountain to the valley then 1 is wrong, 4 is low pressure is wrong, and 3 is correct.

In summary, the diagram is a nocturnal circulation diagram of a valley, so only 3 of the first question is correct.

Look at the second question again, the question is about the night rain, the three places are all on the slopes, and the night wind direction blows from the top of the mountain to the valley, so naturally there is no windward slope, where does the downdraft come from, only the first place is a low-pressure updraft to produce rainfall, so the night rain in the first place is the most.

The correct one in the picture above is copy 2. Explanation: If the place where the first bai is located is the center of high pressure, then the root zhi

According to the flow of air pressure, the other is the flow from high pressure to low pressure, and the isobar line is convex upward, then Figure 134 above is correct, and there is only one correct principle. Then it can be ruled out. Then on the contrary, A is the center of low pressure, according to the principle of high pressure flowing to low pressure, the arrows of 1 and 3 should be reversed, and the isobar of 4 should be convex downward, so 134 is false, so the remaining answer 2 is correct.

First of all, A and D do not have the conditions to form rain, and the rain must have the convergence of cold and warm air currents. The temperature of A is high at night, which is controlled by a single low pressure, and the temperature of Ding is low, which is controlled by a single high pressure, so there is no rain, and the place where the rain is formed is in two places, B and C, and the terrain is steep, and the air flow sinks directly, which is not conducive to the formation of rain, so it is B.

1 pair, 4 pairs (daytime valley blowing wind) sink in the air at 4 places to form high pressure, which does not match the question, and 2 must be wrong.

3 pairs are not correct, which is consistent with the meaning of the question, and 4 pairs are 1 pair, which is also inconsistent with the question.

The second question is Adi. The air flow rises in the valley at night, and there is a lot of convective rain.

There is a lot of rain at night at point A, and due to the influence of the sinking of the cold air mass of the mountain night source, the warm and humid atmosphere at the valley floor rises to form night rain. Du and the first question zhi analysis to see the isobar upward convex words, dao right, that is to say, there is a situation of the same pair, the title says that only one is right, then only 3 is right. The isobar, on the other hand, will not be straight due to the topography.

3. If it is correct, it should also occur at night, when the temperature on the hillside drops rapidly, and the cold air mass sinks and forces the warm air mass at the bottom of the valley to rise.

1 is correct, if A is high pressure, at least 4 to 3 pairs this does not meet the topic, if A is low pressure are wrong, 1 pair. 2 It's not easy to eliminate, the test is the valley wind, and it should be the valley wind. There is a lot of precipitation in C, the terrain slope in C-land becomes larger, the air rises violently, and the terrain is abundant.

(1) Marseille The days are short and the nights are long.

2) Gradually accelerate: the days are shorter and the nights are longer, the days become shorter, and the nights become longer, (3) Warm and humid all year round, affected by westerly winds.

4) Flow erosion V-shaped valley Flowwater accumulation U-shaped valley or trough valley (5)d

6) rising sea levels and inundation of coastal lowlands; affect temperature and precipitation; Affects the water cycle.

456 questions are not all too much to do.

Question 7 Option A, Congo's economy is relatively backward, with rich mineral resources, mainly agriculture and mining.

Question 8 choose C, the Congolese country is economically backward, and the region is in a state of balanced development at a low level.

The summer has the lowest levels of heavy metals.

--The data shows that the turbidity is highest in summer (flood season) [top], and the lower the figure shows that the higher the turbidity, the lower the heavy metal content. The reason for this phenomenon should be that the release of heavy metal pollution sources is relatively stable, and the heavy metal pollutants are diluted in the summer when water is abundant.
