11c I am a liberal arts student in this year's college entrance examination, if you don't understand, I hope to chat with each other privately.

Hello! (The answer to the Wind Lotus Lift 2009 is incorrect, question 10 should be D).

1.a Since Australia is located in the Southern Hemisphere, the Sun is always moving between the Tropic of Capricorn. It's exactly the opposite of China, so China faces yang in the south and Australia faces yang in the north.

2.a Rainfall is affected by topography.

3. a Flows through 5 countries in Southeast Asia.

4. d The triangle of European colonizers in history has deprived Africa of hundreds of millions of elite labor and mineral resources. After a long period of colonial rule, the development was slow.

5. A traditional industries pay more attention to proximity to resources and energy bases.

6. b The terrain causes different temperatures, generally speaking, the higher the height, the lower the temperature.

7. B is the so-called high-tech.

8. b Mainly investigate the influence of latitude and topography. Generally, the temperature on the Qinghai-Tibet Plateau is minus 8 to minus 16 degrees, while the Mohe River is below minus 28 degrees.

9. D Hsinchu Science Park, which is 70 kilometers away from Taipei, is known as "Taiwan's Silicon Valley". From the countryside in the sixties of the last century, it has developed into today's science park.

10. d in the Great Hall of the People in Beijing.

11. c Far from the sea and blocked by tall mountains.

A (key) as the title, for a middle school in my country. It can be concluded that the shadow is facing south or north when the sun shines at noon in a year (because south of the Tropic of Cancer China still has a territorial range, the southernmost 4°N, the shadow will face south). And because when the direct point is located south of the equator 0°, the shadow faces north half of the time, and the direct point crosses the equator to the north (the shadow faces north) most of the time.

Therefore, the shadow can be launched most of the time when it faces north, C = >> north = >> North Star;

b If it is judged to be north, then the sun rises in the spring and autumn equinox from the second place (due east) and sets in the second place (due west).

c (Emphasis) At 12:40 Beijing time, the shortest local shadow is at 12:00 noon, which is 110°E; When the shadow of this 6-meter-tall statue pillar is 6 meters at its length, the sun shines directly on the Tropic of Capricorn.

At this time, the height of the column is equal in length, and the solar altitude angle is 45° (isosceles), which can be pushed out, this place = >>21°34 n [45° = 90° - latitude difference = 90° - (23°26 +21°34 )] = >> This place is located in Zhanjiang, Guangdong, Zhanjiang runs through 20°15 -21°55 north latitude, across east longitude 109°40 -110°55 = >> summer solstice shadow facing south;

d When the sun rises in the east and sets in the west during the day, the shadow is quite long and exceeds the outer ring 6 (as you can imagine and observe) because the oblique illumination is less than 45°.

To add, option C, even if C is changed to A, is wrong. The latitudinal difference between this place and the Tropic of Cancer (23°26 -21°34 =1°52), then tan 88°08 =6 l =>> l=>3

1 square easily fixes flowing sand dunes to maintain soil and water, reducing sand damage and soil erosion.

2. Reduce sand flow and sand damage, plant sand fixing plants to maintain water and soil, reduce desertification and dust storms, and bring environmental benefits.

3. Priority should be given to farmland along railway lines and residential areas.

(1) The height of the sun decreases from the direct point to the surroundings, then the direct point of the sun shown in the figure is on the 0° meridian, the sun height of points A and B of the two 90° meridians is 0°, point C and A and B are on the same isosolar altitude line, the sun height is also 0°, and the latitude range of the solar height can be 0° is the range of polar night, which is to 90°s in the southern hemisphere, choose b.

2) When c and d coincide, the range of polar night in the world is only on the pole, which is the day of the spring equinox or autumnal equinox, the polar night phenomenon does not occur on the day of the Arctic Circle, the noon sun height is 0 °, the longitude of a and b is different, and the local time must be different, the precipitation in the Zambezi River basin will not be too much, it is not easy to flood, the sun shines directly on the equator, and all regions of the world are due east sunrise and west sunset, choose b.

bb.The first question is that because the two points of ab are at the equator and the longitude is 180 degrees apart, it can be judged that this is an isosolar altitude line of 0 degrees, and the focus of its meridian coil is concentrated between the polar circle and the pole, so B is chosen.

The second question is that when the CD coincides, that is, the sun hits the equator directly, the noon solar elevation angle of the Arctic Circle should also be 23 degrees 26 minutes; ab: The longitude of the two points is different, so the local time is different; The Zambezia River is located in southern Africa, with a Mediterranean climate and a wet season in winter; When the sun hits the equator, the morning and dusk circles coincide with the meridian coils, so the sun rises in the east and sets in the west.

I didn't ask a hair.,Who's idle and has nothing to do to help you find a picture.。

1.Most of Asia is in the Eastern Hemisphere, with a few regions in the Southern Hemisphere; Northern Hemisphere.

2.North America is located in the Western Hemisphere, the Northern Hemisphere.

3.Asia is bordered by three oceans: the Pacific Ocean, the Indian Ocean, and the Arctic Ocean.

4.North America is bordered by the Pacific Ocean, the Atlantic Ocean, and the Arctic Ocean.

5.Asian latitude and longitude range: 11°7 south latitude, 77°43 north latitude; 26°3 east longitude to west, 169°40 west longitude east to west.

6.North American latitude and longitude range: 55°40 W, 168°05 W; 7°12 N to 71°59 N.

1 Eastern Hemisphere, Northern Hemisphere.

2 Western Hemisphere, Northern Hemisphere.

3 Arctic Ocean, Pacific Ocean, Indian Ocean.

4 Arctic Ocean, Atlantic Ocean, Pacific Ocean.

5. The latitude range spanned by Asia is about 10°S-81°N6, and the longitude and latitude positions are 25 N-85 N

a is a 180° longitude, latitude is 45°, medium latitude.

The earth turns from west to east and is located in the northern hemisphere, because the arrow in the southern hemisphere will be to the left, and the longitude is not marked back to this point, so point b is 135°E, latitude is 30°, located in the northern hemisphere, and the eastern hemisphere is late in the south.

Look at the direction indicated by the arrow to identify the northern and southern hemispheres, so that you can know the eastern and western hemispheres.
