A geographical problem. Only the answer does not need to be explained.

1: The day and night of the spring equinox and the autumn equinox are of equal length, both 12 hours.

2: Figure C is the Southern Hemisphere, reason: The day and night changes in the period from the autumn equinox to the winter solstice on the map are getting longer and the nights are getting shorter, and the maximum day length is 18 hours to the winter solstice, and the direct sun point is moving from the equator to the Tropic of Cancer during this period, so this map is in line with the day and night conditions of the southern hemisphere during this period of time, so it can be judged that this picture is the southern hemisphere, and there is a period from the spring equinox to the summer solstice, the day and night changes of the map are getting shorter and the nights are getting longer, During this period, the direct point of the sun gradually moves from the equator to the Tropic of Cancer in the Northern Hemisphere, and the situation in the Southern Hemisphere is that the days are getting shorter and the nights are getting longer, so it can also be judged that this picture is the Southern Hemisphere.

3: From south to north: C, B, D, A, C is the southern hemisphere; b is the equator, because the day and night are equinoxized throughout the year; Both D and A are in the Northern Hemisphere, but since the longest night time of D is 18 hours, A has a long polar night, so point A is within the Arctic Circle, which is further north latitude than point D.

In fact, I don't know the specific latitude of point d, it should be in the Tropic of Cancer and the Arctic Circle, I think it is probably the area of Zhalantun (Hulunbuir grassland, north of Manchuria), my brother stayed there a few years ago, according to him, the night time is very long in November, and the sun rises at 3 o'clock in July, which is quite similar to the situation in Figure A.

It's hard to type, remember to give a reward, o( o

1.Day and night are of equal length, with an average of 12 hours.

Reason: The equinox is equinoxical to the global diurnal equinox.

Located in the Southern Hemisphere.

Reason: AD These two points on the winter solstice (December 22) are long days and short nights.

3.Four locations are listed from south to north: ADBC

Reason: The day length of the winter solstice at point A is 24 hours, indicating that point A is located; The day length of the winter solstice at point D is about 18 hours; The summer solstice day length at point C is about 18 hours, indicating that the latitude of the two points DC is the same (both are located in higher latitudes, which are lower), point D is in the southern hemisphere, and point C is in the northern hemisphere; Point B is the same length of day and night throughout the year, indicating that point B is located on the equator.

x° is the north latitude, the ratio of the day arc to the night arc on the x° latitude coil on that day is 5:7, and the short day arc indicates that it is the winter half year (23 question a is directly excluded).

It can be judged that ab is the arc of the day.

On x, the day is 10 hours, and the night is 14 hours, and the vertical line at point A is the meridian at 12 o'clock in the diagram at this time.

So it comes to point B and it's 7:00 a.m

When the solar height at point b is at its maximum, Beijing time is 10 o'clock, which means that the meridian where point B is located is 150°E, so the meridian where point A is located is 135°W (150°E moves 75° eastward), and A is the tangent point between the morning and dusk line and 70°N, indicating that 70°N and 90°N are polar nights.

A moving southward indicates that the polar night in the Northern Hemisphere is getting larger, and B is paired.

x in the Northern Hemisphere, the Northern Hemisphere sees the sunrise in the northeast and it is summer, c excludes.

As for d, (135°W, 70°N) does not need to know what kind of wind blows in the winter half of the year.

23 questions are selected and B24 questions are not solved.

After analyzing 23, 24 will naturally know.

Also, a is written incorrectly, and 22 should be changed to 20.

Normal solution 20°S, 135°W

It's simple to say, I don't understand the question, but it's okay to add me hi to ask.

(1) Option BNorthwest wind.

As you can see from the graph, its winds are deflected to the left (the inner subtropical high near 30 degrees north latitude is close to 0 degrees, the extreme high pressure equatorial low near 60 degrees is the extreme subpolar depression, the high pressure from the wind, the low pressure), and this ** shows the Southern Hemisphere. In the Southern Hemisphere, westerly winds prevail in the northwesterly.

2）a.B is a well-known figure at 135 degrees east longitude and latitude is hot and dry, in the subtropical high pressure central inland Australia and Capricorn years control the southeast trade winds Tropic of Cancer, is the formation of a tropical desert climate, the climate is characterized by hot and dry years.
