1. The distance of one degree in any longitude is 111 kilometers, and only the equator on the latitude is like this.
Second, this question is to be asked by the district, right? First of all, you have to determine which time zone the place is in, that is, divide the longitude of the place by 15, and if the remainder is less, the time zone used by the place is directly the quotient. If it is greater than, the time zone used for the place is quotient plus 1.
For example, Beijing (116°E, so Beijing's time zone is East 8) is now 12 o'clock, and London (0°, so London is zero) is 4 o'clock. The difference between the two is 8 time zones east plus west minus, and London is west of Beijing, so London time is 4 o'clock.
3. This has little to do with perihelion and aphelion. The high temperature in summer in China is mainly related to the size of the direct angle of the sun and the length of sunshine time, because the direct point of the sun in summer in China is in the northern hemisphere, the sun altitude angle is large, and the sunshine time is long, so the temperature is high. Rainy is related to China's monsoon climate, because China is located on the largest continent and the largest right bank of the ocean, the difference between sea and land heat is very large, so the monsoon caused by the difference between sea and land heat is the most typical in East Asia.
Fourth, the angle between the axis and the ecliptic plane is indeed 66°34. The yellow-red angle is 23°26. The yellow-equatorial angle is the angle between the plane of the ecliptic and the plane of the equator. The angle between the axis and the ecliptic plane is the angle between the earth's axis and the ecliptic plane, that is, the co-angle of the yellow-red angle.
Fifth, this statement is correct. Only on the winter and summer solstices will there be polar day or night in the Arctic and Antarctic Circles. Except for the spring and autumn equinoxes, the North and South Poles are not polar days and polar nights.
Sixth, this is difficult to say, because the earth itself is not a regular sphere, how can it require its regular operation. As for whether he will correct to the vertical rotation and the standard circular motion of the sun, it is estimated that it is difficult.

1 You know that the earth is round, and all meridians are of equal length, but the parallels are different, on the same meridian, each degree of latitude is about 111 km, but the distance of each degree of longitude (except for the equator, which is 111 degrees) varies from 0 km to 111 km (the higher the degree, the shorter it is). Its distance varies with latitude and is equal to 111km times the cosine of latitude. That is, 60 degrees north latitude, which is a kilometer.
However, this distance is not the shortest distance between two points separated by one longitude, the shortest distance is the distance of the arc connecting the two points in the great circle, which is a little smaller than the distance calculated above. (This relates to the issue of shipping routes).
2 time zone problem, pay attention to east longitude 180 on the line, after every 15 degrees to the west to decrease by 1 hour, to the west east will increase, for example, east longitude 120 is 12 o'clock, then west longitude 15 is about 5 o'clock, and for example, west longitude 165 is 12 o'clock, if you want to find east longitude 165, you can also add it like this, plus 22 hours, it is 12 o'clock the day before, anyway, the time in the east is fast.
3 In summer we are at aphelion, winter is perihelion, but the point of direct radiation is different, summer direct to the northern hemisphere, winter direct to the southern hemisphere, high temperature and rain related to our climate, and the formation of climate is a lot of factors. The direct sunlight time is the long sunshine time, and this kind of tangled question is generally not asked.
The angle between the ecliptic plane (that is, the plane formed by the cross-section of the earth and the irradiation of the sun, yellow refers to the sun, and the ecliptic refers to the earth) is degrees, so the polar axis and the ecliptic plane are 66 degrees and 34 minutes.
The polar day and night phenomenon is only within the polar circle, you can imagine that the appearance of the polar circle is generated by the movement of the direct point of the sun, so you can simulate, the vernal equinox, the earth's day and night equinox, at this time the sun directly hits the equator, and then the sunlight moves northward, so now there will be a polar night phenomenon near the North Pole, and there will be a polar night phenomenon near the South Pole, with the northward movement of the sun, the phenomenon of the polar day and the night continues to expand, the road, the summer solstice, North of 66 degrees 34 minutes in the Northern Hemisphere, there is a polar day in the Arctic Circle, and a polar night occurs within the Antarctic Circle, and then it moves northward again, to the autumn equinox, to the south to the winter solstice, and the cycle continues.
The last question should not be a question you should know, you better study hard, geography is broad and profound.

Question 1: Longitude is 1° corresponding to 111 km. But this is not the case at latitude, only at the equator. When calculating the latitudinal distance for other regions, it is calculated as follows: 111 * cos a * degrees.
Question 2: Calculate the degree difference between the two places to see if it exceeds 180°, and then divide by 15. For example, Cape Town is located at 18°E in Zone 2 East and New York is located at 74°W in Zone 5 West, which is calculated as:
74+18)/15 =6...2. Because 1° differs by 4 minutes, there is a total difference of 6 hours and 8 minutes. According to the principle of East plus West subtraction, 15:27 minus 6 hours and 8 minutes, we get 9:19 New York time.
Question 3: It cannot be said that it is because of the distance of the sun. China is backed by the largest continent and faces the largest ocean, forming a typical monsoon climate.
The climate is affected by many aspects, such as: geographical location, solar altitude angle, altitude, etc. You should be able to see it in the book.
Fourth question:. The number of angles of the yellow equatorial is equal to the line of gravity, tangent to the polar circle, and the earth's axis is perpendicular to the equator, so the ecliptic plane (the plane of the earth's orbit) and the equator are 23°26, and the earth's axis is 66°34. If you look at the map, Australia hasn't crossed the Antarctic Circle, so there is no polar phenomenon.
Question 5: You're right.
Question 6: The orbit of the earth is an ellipse. As for why the earth is tilted, I suggest you ask your physics teacher. Also, I don't think the Earth rotates vertically in a standard circular motion with the Sun.

d Because it is in the Northern Hemisphere, it is only necessary to consider the solar altitude angle on the winter solstice, and the solar altitude angle should be 90-(35+ is approximately equal to 30 degrees, and the angle between sunlight and the horizontal plane is roughly 30 degrees, mn
The horizontal distance is 30 meters, and the vertical distance is also 30 meters, so the N place to build a viewing tower only needs 30 meters of the horizontal distance multiplied by tan30 ° plus the vertical 30 meters, which is equal to 48 meters. There seems to be no answer.
But the noon solar altitude angle on the winter solstice is actually greater than 30 degrees, so it should be greater than tan30°, so the number 30*tan30° should be a little smaller than the answer, and the answer greater than 48 is only 50
There's no diagram, it's hard to explain, so I'll just try my best to get here, I hope I'm right.

1a International Standard Time (UTC) is Prime Meridian Time.
Later than y o'clock. 2 hours is a time zone.
The longitude is obtained by combining the direction of the Earth's rotation.
Y o'clock is on the morning and dusk line.
So the direct point of the sun is in the northern hemisphere 2b
3cd2 and 3 are hard to say.
Take the summer solstice as an example: the direct point of the sun on the summer solstice is 23°26 n, the latitude of Beijing is 40°, and the latitude of Guangzhou is about 23°. >>>More
The relationship between the two is rather ambiguous - I haven't touched these for many years. Try to explain: >>>More
As can be seen in the figure, when the sunlight enters the window, the solar altitude angle is the smallest, so the sun stone shines directly on the Tropic of Capricorn on this day, that is, the winter solstice, and the northern hemisphere is winter at this time, so a b c is wrong, and the first question is d. >>>More
These two sentences are actually to give you a better understanding of the difference between weather and climate. According to its meaning, weather is the characteristics of the climate in a short period of time, such as rain, snowfall, temperature drop and rise, wind, and the weather can change at any time. >>>More
The question of time zone involves many aspects, and the question is very flexible. >>>More
