Geography questions, the tenth question I don t understand, some geography questions

This year it was B, but last year it was D, because it was the winter solstice, the days were short and the nights were long, and the sun did not come out until after 6 or 7 o'clock.

d。。Beijing belongs to the northern hemisphere, on June 22, the sun shines directly in the northern hemisphere, and the sunrise is earlier than 6 o'clock, and on December 22, the sun shines directly on the southern hemisphere, and the sunrise is later than 6 o'clock. On March 21 and September 23, the sun shines directly on the equator, and the whole world rises at 6 o'clock.

Choose C, because when the sun shines directly on the Tropic of Cancer, the sun rises earliest in the area where the Tropic of Cancer is doubled

d Sunrise at 7:30 a.m., later than 6:00 a.m., indicating that the days are short and the nights are long in Beijing at this time.

On the 22nd of the month, the sun shines directly on the southern hemisphere. Sunrise is the latest of the year.

d The sunrise is late in winter.

d, the idea is as follows - first of all, you have to master a knowledge point - the spring equinox, the autumn equinox, the global day and night are equinoxical, and the global sunrise time is 6 o'clock. Then, compare the sunrise time in the question - 7:30 o'clock last year - sunrise - later than 6 o'clock (excluding AC), it can be seen that this time is longer than the night of the spring or autumn equinox, and the days are shorter - excluding b (6-22 is the summer solstice in the Northern Hemisphere, this day is the longest day in the Northern Hemisphere, naturally longer than the spring and autumn equinox), and finally D is the correct answer.

d, because the sunshine hours are short, it is winter.

It's earlier than six o'clock, so it's summer.

That's a fraction of the score.

The process is refined, the efficiency is high, and there are many industrial centers.

The specific gravity is small and the level is high.

The system is perfect, the quality is excellent, and the pillar industry is a pillar industry.

Kenya. It's so tiring.

b 2 is absolutely right, 3 belongs to the rational use of wasteland, and c can be considered because 1 is not very sure.

Every 1° latitude on Earth, the length of the meridian is 111 kilometers. So 8,500 kilometers is used to tell you that the distance between A and B is no more than about 77 degrees

And because the shortest distance between two places must be the maximum arc between the two places and the center of the earth, that is, the spherical distance between the two places. They have to agree with each other that the arc goes south and then north, and there is only one possibility: the arc passes through the southernmost point on Earth, the South Pole.

So the answer is near Antarctica.

And that 8,500 kilometers, or 77° latitude, is used to rule out the possibility of near the equator, so to sum up the above answer: choose b

b A and B are at both ends of the South Pole, and the short-range line of A and B passes through the South Pole.

So, the most recent way to go is to go to the South Pole first, and then to the other point.
