High School Geography Select One to Solve Question 2

You can draw a picture.

The low pressure trough has high air pressure at the southwest end, and the low pressure center is in the northeast.

This trough line is the left trough line of the low-pressure system, which can be known according to the principle of left cold and right warm.

The precipitation should gradually decrease, the air pressure should gradually decrease (from cold high to warm low), the temperature should gradually increase (cold air mass to warm air mass), and the wind speed should first become larger, then smaller, choose B.

d Analysis: Generally, the higher the latitude, the smaller the diurnal variation of the solar altitude angle and the smaller the diurnal range of temperature. The slope slope increases, the runoff velocity increases, the kinetic energy increases, and the erosion of the slope surface is enhanced. However, when the slope reaches a certain level, the slope flow decreases due to the decrease of the rainfall area of the slope, and the erosion of the slope is weakened.

From the equator to the Tropic of Capricorn, the maximum difference in the angle of solar elevation at noon is increasing, but the Tropic of Cancer to the pole does not change. From the winter solstice to the summer solstice in the northern hemisphere, the direct point of the sun moves northward, and the day length of Haikou becomes larger.

D Analysis: According to the existing conditions, it can be inferred that the curve is a cold front (the left low pressure trough of the frontal cyclone), the northwest side is a warm air mass, the southeast side is a cold air mass, the front moves to the northwest, from the southeast to the northwest, from the front to the front, the cold air mass to the warm air mass, and the precipitation decreases (the cold front precipitation is behind the front); The temperature is gradually rising; The speed of the Internet gradually decreases (the cold air mass is strong and the warm air mass is weak); The air pressure decreases and then rises (through a low-pressure trough).

Under the control of the equatorial low pressure throughout the year, the high temperature is high throughout the year, and the updraft prevails, which is prone to clouds to rain.

The Amazon River and its tributaries bring abundant water to the rainforest.

The terrain is open to the Atlantic Ocean, which ensures a constant flow of water vapor**.

The area is located in the equatorial low pressure zone, accompanied by precipitation, and belongs to the tropical rainforest climate.

The Amazon River is the largest river in the world, and the region is ideal for rainforests due to high temperatures and rainfall throughout the year.

1) The size of the settlement is related to the natural and human characteristics of the area, and the larger the scale, the greater the function within its scope, and the more people will be able to complete it, and the greater the travel expectation. For example, if I want to buy something that is not sold in a small town (small settlement), I can only go to a larger town (large settlement).

2) The construction of the actual traffic line should consider the actual passenger and freight flow, which is naturally related to travel expectations.

Question 1: AC is negatively correlated As you can see from the figure, the three large circles are close to each other, so the travel expectation is larger.

Needless to say, the second question will not be mentioned.

1. Point C is located at the midpoint between point A and point B, so the time of point C is located at the midpoint between point A and point B.

Point A is located at the intersection of the morning line and the equator, so the time at point A is 6:00;

Point b is the intersection of the morning line and the Antarctic Circle, which represents the moment of sunrise in the Antarctic Circle, which is determined by the local day length, which is calculated by subtracting half of the day length from 12:00, which is related to the sunset moment (12:00 plus half of the day length) about 12:

00 symmetry. That is, the shorter the day, the later the sunrise moment. For the purposes of this question, when the daylight range of the Antarctic Circle is exactly from the B meridian to the 20 degrees west longitude, the day is the shortest, and the time at point b is the latest.

In other words, the intersection of the Antarctic Circle and the Antarctic Circle is exactly 20 degrees west longitude. Then the meridian where point B is located and 20 degrees west longitude are symmetrical about the 12 point meridian (30 degrees west longitude), so the meridian where point b is located should be 40 degrees west longitude, point c longitude is 80 degrees west longitude, and the local time is 8:40 minutes, so D is chosen.

2. At this time, 120 degrees west longitude is 6 o'clock, then 150 degrees east longitude is zero point, and 180 degrees (date line) is 2 points, so today's range (150 degrees to 180 degrees east longitude) is 30 degrees, that is, 1 12 of the whole day, Beijing is located at 116 degrees east longitude, which belongs to yesterday's range, accounting for 11 12 of the global proportion, so choose c.

3. The day length of the Arctic Circle is equal to the night length of the Antarctic Circle, and it can be seen from the analysis of Question 1 that the maximum day length of the Antarctic Circle at this time is from point b (40 degrees west longitude) to 20 degrees west longitude, that is, 20 degrees of longitude, 1 hour and 20 minutes, then the night length of the Antarctic Circle is 22 hours and 40 minutes, so B is selected.

Let's take a look at the teachers' discussions.

The first brother answers two questions: choose D

The summer monsoon in May is roughly located a little north of the Pearl River Basin, and the location of Nanjing is controlled by the winter monsoon, so it is impossible to have stormy and rainy weather. In June, the summer monsoon moved northward to the middle and lower reaches of the Yangtze River, and the warm air and cold air met to form a front. As the cold and warm air are evenly matched, the front swings back and forth to form a quasi-stationary front, and rainy weather may occur in Nanjing.

Answer B is incorrect. In July, the summer monsoon continued to move northward, with the frontal rain band moving to North China and Northeast China, and the middle and lower reaches of the Yangtze River being controlled by a single subtropical high, which was hot and dry. The cyclone is formed by the center of low pressure, and the answer C is wrong.

In August, the frontal rain belt continued to control North China and Northeast China, and the middle and lower reaches of the Yangtze River were controlled by the subtropical high, which was hot and dry. The answer D is correct.

10.A is between 100-200 and B is between 0-100, so the height difference between the two places is between 0-200, so the answer is A

11.There are two key points, one is the judgment of m and n elevations. m is between 300-400, n judgment, to use the contour line to make an important conclusion, that is, greater than the large, less than the small. Take a look at a**.

So n is between 100-200.

Another key point is that the hatch passes through the river valley. Since it is a river valley, it must be low in the middle and high on both sides. The profile should be displayed. And it is close to m.

This makes it possible to determine that C is the correct option.

11.Note the time "April", when the direct point of the sun is in the Northern Hemisphere. At this time, the global pattern of day length is that the further north you go, the longer the days get. Then look at the latitude of the four places, from north to south, the order is 3412On this day, the daylight is arranged from longest to shorter as 3412
