Counterclockwise from the direction of the Earth's rotation, it is a top-down view over the Northern Hemisphere.

Figure B shows that the Arctic Circle is exactly in the day hemisphere, and the current date is June 21, the summer solstice.

Beijing is located at 120°E, just near the dusk line, it can be judged that the current time is roughly 18:00b From the earth's rotation direction card, it is judged that B is the autumn equinox (because it is known that A is the summer solstice), the autumn equinox is generally September 22 or 23 every year, and the National Day of Chinese mainland is October 1, so choose B

Point P is at the equator, and the sun is directly shining on the Tropic of Cancer on the summer solstice, so it can be seen that the noon solar height of point P = point Q is located at the intersection of the meridian of 135°W and the morning and dusk line, and it can be seen from Figure B that point Q has 1 4 days in the dark night, and 3 4 days in the daytime, that is, the day length of point Q is 3 4 * 24 = 18 hours.

West-north, in the direction of the morning and dusk line. You'll see the sun hovering overhead, round and round.

Because point m is the Arctic Circle, the speed of the plane is 1000 kilometers per hour, which means that the plane can reach point M on the same day, because it is the summer solstice, the Arctic Circle is completely in the polar daylight state, and the sun will not set below the ground level.

Question 3 Day length 0 Question 4 North The sun never sets.

1 Find the direction of the earth's rotation 2 Determine the point where the sun shines directly 3 Specific problems Specific analysis.

These seem to be in the books, the child reads more books, looks at more notes, if there are no notes, then forget it. I don't think anyone can help you with this kind of question.

You don't even bother to flip through the books, and you ask so many questions at once.

1.It is necessary to determine the option based on the material information, but it is clear that Apple dominates the microelectronics industry and does not have high requirements for raw materials, and A is wrong.

2.Foxconn is labor-intensive, and you must choose A.

3.It can be excluded by the first question.

Suggestion 53, Sunshine Plan, Guidance and Practice.

What's the question? If there is anything that won't ask you.

1.Temperate monsoon climate.

2.Mediterranean climate.

3.The west coast of the continent at 30°-40° north and south latitudes.

4.。In summer, under the influence of the Pacific subtropical high, the summer monsoon prevails 5In summer, the pressure belt and wind belt move northward, and under the control of the subtropical high, the airflow sinks, resulting in drought and little rainfall.

(1) temperate deciduous broad-leaved forest; temperate steppe zone; temperate desert zone (2) coastal to inland; Moisture content; Middle.

3) temperate monsoon climate; Sparse grasslands, wind.

4) irrigation water sources; Non-zonal differentiation.

There is no diagram, it may be tropical, temperate, cold.

The distribution of the natural zone from east to west along the latitude of 40°N reflects the differentiation law of the dry and humid zones in the natural zone. The occurrence of this distribution law is mainly affected by precipitation conditions. Globally, this pattern is most typical at latitudes 30-40.

2) The distribution of the natural zone from east to west along 40°N latitude reflects the differentiation law of the natural zone from coastal to inland. The occurrence of this distribution law is mainly affected by the distribution conditions of sea and land. Globally, this pattern is most typical in the mid-latitudes.

Under normal circumstances, a year is 365 days, but a leap year is 366 days, 2008 is a leap year, 29 days in February, so it is 366 days, and the reason why it jumps from 367 days to 366 days here is because the Olympics started on August 8, 2008, and there are 31 days in August every year, so there is one more day, so it jumps from 367 days to 366 days.

Because 2008 was a leap year, there was one more day.

Land topography People divide terrain into five basic types: mountains, plains, plateaus, basins, and hills. According to the characteristics of its formation, it can be divided into two categories: one is renewable resources; One category is non-renewable resources.

Mountains have a thick crust and are dominated by continental crust.
