High school geography perfect holiday winter vacation homework answer

1. The photos shown below were taken by the photographer with continuous exposure technology at night. The arc in the photo is the apparent motion trajectory of the star. Read the picture and answer questions (1) to (2).

(1) According to the picture, the photographer's shooting location is located in ()

A. Low latitude area B. Mid latitude area

C. Near the North Pole D. Near the South Pole

(2) In the picture, the angle of the apparent motion of star A is about 5, so it is judged that the photographer's continuous shooting time is ()

A. More than 1 hour B. The elevation of Polaris is equal to the local geographical latitude. Seen from the picture, the elevation angle of Polaris is small, so it was shot at low latitudes. Question (2), examine the earth's rotation period through the apparent motion of stars. The apparent motion of stars is essentially a reflection of the earth's rotation. The earth rotates 15 degrees every hour, so it takes more than three hours to shoot continuously.

Answer (1)A (2)B

2. A research study group in a middle school in Fujian designed an adjustable window visor to achieve good shading and lighting in the classroom. The following figure shows the design principle of the sun visor, and answers questions (1) to (2) accordingly.

(1) When the sun visor is put away, and the indoor midday sunlight area reaches one year's value ()

A. The world is divided equally between day and night B. It is summer in the northern hemisphere

C. The area south of the Antarctic Circle is extremely daytime

(2) Jinan Middle School draws lessons from this design. If the windows in the two places are the same in size and shape, the adjustment should be made as follows: (). Shorten the sun visor ③ The sun visor length remains unchanged, reduce the installation height ④ The sun visor length remains unchanged, and increase the installation height < P > A.13B.1④ < P > C.23D.2④ < P > Analyze the first question (1). Fujian, located in the northern hemisphere, should put down the sun visor in summer to avoid the indoor temperature from being too high due to light irradiation, and should take up the sun visor in winter to let as much light as possible into the classroom to improve the classroom. Therefore, it is the winter solstice day in the northern hemisphere when the indoor midday sun illumination area reaches one year. So choose D. Question (2): The latitude of Jinan is higher than that of Fujian, and the height of the sun at noon in winter and summer solstice is lower than that of Fujian. Therefore, in order to achieve the same effect as that of Fujian, Jinan can achieve it by lowering the installation height of the sun visor or lengthening the sun visor. So choose a.

As shown in the following figure: (Take putting down the sun visor on the summer solstice as an example)

Answer (1)D (2)A

3. A seagoing vessel set out from Shanghai for San Francisco, USA. When the seagoing vessel passes through point P in the figure, it is at sunrise, and the EF line in the figure represents terminator line. Read the picture and answer questions (1) to (2).

(1) At this time, the direct point of the sun is closest to ()

A.15 N, 135 EB.15 S, 135 W

C.23 26 ′ N, D.23 26 ′ S, 18°

(2 2) The following phenomena occur at a time similar to the date when the seagoing vessel passes through point P ()

A. Winter wheat is being planted in the Jianghuai Plain

B. The middle and lower reaches of the Yangtze River are in the rainy season

C. The days in Beijing are the shortest in a year

D. The annual flow of the Tarim River

Analyze the first question (1). Exclude options a and c. According to the fact that EPF︵ ~ crosses the Antarctic circle and is tangent to a latitude circle, it can be known that the sun can't shine directly at 23 26 ′ s, and item D is excluded. Question (2) examines the geographical significance of the earth's revolution. According to the relationship between the terminator line and the longitude and latitude lines, it can be judged that item C is wrong when the ocean liner passes through point P and the sun shines directly on a point north of the Tropic of Capricorn in the southern hemisphere. Meiyu appeared in June, and item B was wrong. The main recharge source of Tarim River is the melting water of alpine snow and ice, and the period of flow is in summer, and the D item is wrong. Winter wheat is sown in the Jianghuai Plain around October, and item A is correct.

Answer (1)B (2)A

4. There are five equal points on the morning and evening circle. If one of them happens to be at 12 o'clock, the shortest line on the sphere between two non-adjacent points may ()

A. Sunset occurs at the same time. B. Passing through the direct point of the sun

C. It is a parallel with fixed latitude. D. It is the dividing line between the two dates. (2) The points on the terminator line are all on the same great circle, and the shortest distance between two adjacent points is the bad arc on the terminator line between these two points. According to the question, one of the five equal points on the twilight circle is exactly 12 o'clock, which means that the shortest line on the sphere between two points that are not adjacent to this point (that is, the bad arc of terminator line) cannot pass through the direct point of the sun, and item B is excluded; Terminator line can't coincide with the parallel, and item C is excluded; One of the dividing lines between the two dates is the o'clock meridian, and the other is the 18 meridian. At this time, the o'clock meridian is just opposite to the 12 o'clock meridian, so the "spherical shortest connecting line between two non-adjacent points" cannot coincide with the o'clock meridian or the 18 meridian, and item D is excluded.

Answer A

The chart below shows the daily variation of solar radiation reaching the ground observed in a certain place in China. Complete question 5.

At 19: 12 on July 27, London should be located near the faint line in the daytime hemisphere, and London is located in the night hemisphere in C and D pictures, so it is excluded.

Answer A

A scientific research team returned to Site P on April 21st after a two-month sea expedition. The following picture shows the ground situation of the area where P is located at a certain time of the day. Read the picture and answer question 9.

9. The day length of the expedition team is 11 hours on the departure day, and when it returns to P, the day length of P is about ()

A.1 hours B.11 hours

C.13 hours D.14 hours

Analyze this question to examine the change of day and night length. According to the materials in the title, the date of departure from P is about February 21, one month from the vernal equinox (March 21), and the day length is 11 hours; At the vernal equinox, the sun shines directly on the equator, and the day length of P is 12 hours. It can be seen that the departure date and the vernal equinox are one month apart, and the day length is one hour apart. On April 21, the direct point of the sun was located in the northern hemisphere, and the time was one month different from the vernal equinox. Therefore, when it was pushed out and returned to P, the day length of P was about 13 hours, so C was correct.

answer C

1. the latitude difference between the surface point q and the latitude where the direct sun point is located is α, and its noon sun height is H. If H is equal to α, the latitude range of Q point is () < P > A.21.5 to 68.5 B.11.5 to 68.5°

C.21.5° to 78.5 D.11.5 to 45 < P > This topic is an examination of the noon sun height and computing power. According to the noon sun height formula H = 9-| φ δ |, where φ represents the latitude of a certain place and δ represents the latitude of the direct point, we can get: H+| φ δ | = 9, and H=α according to the material, where α is the latitude difference. If we solve the equations formed by the two equations, we can get | φ δ | = 45, and δ is at .
