How to do this high school geography.

2) AD is the morning line, and the point on the west side of this line (night) will enter the east side (daytime), so the direction of the earth's rotation is clockwise, so it is a diagram of the sky above the South Pole. The central point is the South Pole, which is the Southern Hemisphere.

3) The distribution law of the linear velocity of the Earth's rotation is as follows: except for the north and south poles, it is equal everywhere (15 degrees and hours), b=c=d

4) On this day, the polar day phenomenon occurs in the Antarctic Circle and its south, indicating that the sun is directly shining on the Tropic of Capricorn, so it is before and after. The distribution of the height of the sun at noon decreases from the Tropic of Cancer to the north and south, so a=c>b>d (ac is at the equator).

5) A is on the equator, and the morning line is always 6 o'clock sunrise, so a is 6 o'clock; Point d is facing away from the sun and the direct rays are shining, so it is 12 o'clock.

6) Rotate from west to east, 60° to 90° west, the geographical coordinates of the direct sun point: (30°W, 23°26 N).

7) The length of the day looks at the arc of the day, that is, the weft coil where point A is located is divided into two halves by the morning and dusk lines, and the length is compared, and the day and night are of equal length.

The parallels where point d is located are all within the range of the day hemisphere, so the day is 12 hours long.

4)c=a﹥b ﹥d

6)30°w,23°26′s.

If you write everything else correctly, I won't repeat it.

Classmate, don't you know how to ask the first question?

1. The figure shows that the land price in this area is ** as a whole, and the land price in the urban area in A should be **; c. If the population of the suburbs is concentrated in the city center, then the land price in the urban area will be larger, and the land price in the suburbs should be lower; With the development of the economy, the scale of the city should be expanded, and the scope of the city in the figure includes urban and suburban areas, and the scope of the suburbs is not reduced. When it comes to the impact of traffic, the most important factor affecting the land price is the distance from the city center and the accessibility of transportation, because the overall land price is not the impact of the distance from the city center, it may be that the transportation in this area is convenient, people are convenient to socialize, and the land price is **.

2. Observe the location of A: in the suburbs, far away from the urban area; Moreover, the range of land prices is very large, and it is the highest land price in the suburbs. The location required by ABC is a large area, the lower the natural land price, the better, the economic profit is lower, and the high land price cannot be paid, so the suburbs are more suitable.

High-tech development zones require a beautiful environment, high profits, and can afford high land prices.

1.The dotted line is the land price in 2005, and the urban land price is significantly higher than that in 1985. At the junction of urban and suburban areas, the land price curve in 2005 has increased significantly, indicating that the transportation accessibility here is good (one of the factors affecting land prices). The suburban land price ** is larger than that of the urban area, which does not indicate that the suburban population is concentrated in the urban area, and item c is wrong; Item D cities are expanding rather than shrinking.

2.High-tech development zones should be located in the suburbs with high transportation accessibility and beautiful environment.

Question 1 The horizontal axis is the distance, and the vertical axis is ** According to the comparison of land prices between the suburbs and the city center in 1985 and 2005, it can be found that the gap has narrowed, because the economic development and transportation are developed, and the time from the city to the suburbs has been shortened, and because of the suburban environment, people will choose to buy houses in the suburbs, so that the housing prices **.

Question 2: Mining areas, dairy farms, and commercial grain bases are all large-area, and the land price in place A is relatively high, so they should be built in the suburbs.

（1）20°n，135°w；

3) the direct point of the sun moves southward; In the Southern Hemisphere, the days become longer and the nights are shorter;

The diagram is a map of the Northern Hemisphere, and the Earth rotates in a counterclockwise direction. In the diagram, OB is the meridian at 0 o'clock local time, and OA is the 180° meridian. The longitude of the OB is 115°E.

I don't know what else you want to ask?

The answer to the second question: Item D is correct: A reaches the meridian where B is located 60 degrees of longitude to the east, which is the inferior arc, and A can reach the meridian where B is located by 300 degrees of longitude to the west, which is the superior arc, and the direction should be judged by the inferior arc, as illustrated, so A is in the southwest direction of B.

1. Measure the distance between 20s --- 60s (using the formula l=111*x, x is the latitude difference).

l=40*111

Measure the length of the inferior arc between 170e --- 130w (using the formula: l=111*x*cos@, x is the longitude difference, @是当地的地理纬度).

l=60*111*cos60

The Pythagorean theorem tells that the distance of the hypotenuse is 5550 km.

The answer is: B2, C north-south direction unchanged, but east-west direction, remember the inferior arc to see the position, the longitude difference between the two places should be less than 180 degrees, if greater than 180 degrees, the east and west are interchanged.

In the second question of BB, you think about a three-dimensional map of the earth, which is clockwise because it is the South Pole. 130w……170e, which is east in the direction of 170e, is southeast of B in place B.

Finding the distance on the ground is like finding the hypotenuse of a triangle Latitude 1° 111km 60°-20° = 40° 40° 111 4440 is the side of the triangle.

Because A and B are located in different hemispheres, the two longitudes are different.

180°-170°)+180°-130°)=60°Because the distance between the two meridians is found at 60°s, the longitude is 1° 111 cos km (for the latitude where it is located).

So 111 cos60° 60° 3330 is the other side of the triangle.

Using the Pythagorean theorem, the distance to the field is 5550

The answer to the first question is b

The second question depends on the location of the two places, and we should start with the longitude of the two places.

So add the two places longitude, if it is less than 180°, then the east longitude location is in the east, the west longitude location is more than 180° in the west, then the east longitude location is in the west, the west longitude location is in the east, the two places of longitude are in the east, and the longitude of the two places is increased by 180°, so the east longitude location is in the west, and the west longitude location is in the east, and from the map, place A is located in the southeast direction of place B.

So the second question is b
