Are all meridians parallel, and if not, then parallel from the point of view of regional time?

Do you know what a meridian is, if you can recognize the meridian on a globe, you will know that the meridian will not be parallel.

To talk about the relationship between time zones and meridians, look at peeled oranges.

Let's take a look at the dividing line between each two petals as a meridian and each petal as a time zone

The fact that one line is most widely spaced in the middle and the closest at both ends indicates that the "meridians", that is, the lines between the valves, are not parallel.

However, there is a time zone within a petal, but it is the same time zone, and there are fewer places at both ends of the tube, and more places in the middle tube. That is to say, in the same hour, it should rotate so wide in the middle, and only a very narrow point at both ends. In the "middle" of the Earth, that is, on the equator, it will move 15 degrees in an hour and about 1,650 kilometers, and at the two ends, that is, the poles, although it also moves 15 degrees, because all the meridians are almost crowded together, the position of the movement in one hour is almost zero.

It's like the axle and wheel of a bicycle, in the same amount of time, the wheel turns in one circle, the axle also turns in one circle, and the wheel is a long distance on the ground, and the axle is placed on the ground, and its circle is only a small distance.

The meridians are not parallel, they are relative to the poles. If you really want it to be parallel, then you can only draw two parallel lines on the ground, note that it is on the ground, but do not extend it indefinitely, then it will still intersect.

This is the content of surface geometry, so let's look for this information.

Time zones are artificially defined and have nothing to do with whether the meridian time is parallel or not.

The meridians are not parallel. The meridian is the arc of the earth's surface that connects the north and south poles and is perpendicular to the equator, and will intersect at the north and south poles, so the meridians are not parallel to each other. The warp, like the weft, is an auxiliary line that humans have assumed for the convenience of measurement.

The meridian, which indicates the north-south direction, is also called the meridian. Two warp threads facing each other form a warp coil. The warp coils are all large circles with the center of the earth as the center, and they are handed over to the poles of the earth.

The meridians indicate due south and north, and all meridians are approximately equal in length.

Prime Meridian:

The prime meridian is also known as the zero degree meridian.

It is a standard reference meridian established for the determination of geographic longitude and the measurement of coordination time. The earth has a natural zero-degree latitude equator, but there is no natural zero-degree longitude. With the development of the maritime industry, this situation of each grinding and traveling for government has gradually changed.

In 1767, Mascolin, director of the Greenwich Observatory in the United Kingdom, compiled the "British Nautical Astronomical Calendar", which is based on the Greenwich meridian in London, England.

For the zero meridian of the earth and the celestial sphere, the spring wanders.

Target. The book was quickly adopted by many navigators after its publication.

The meridians are not parallel. Geography. Target.

View. There are many types, main view (side view), area view, and polar top view. The main view is the whole thing that you usually see.

Earth. Halfway up, the top view of the polar region is from the polar regions.

Airspace. Looking down, both of these are seen at the intersection of meridians and at the poles. And the area view, similarly.

Map of the area Bi Bao Qin.

Most of the meridians you see are parallel, but if you look closely, you'll see that they are not parallel. On a regular map, the view of the low-latitude region is relative to the high-latitude area.

, the meridians are relatively parallel. But if you take out a very small area, the meridians can be drawn parallel (excluding the pole area). For example, the earth is far away, but you don't find that the road you are walking is uneven, this is one.

Reason. Warp and.

Parallel. are perpendicular to each other, wefts.

Between. Parallel to each other, if the earth is a piece of paper (flat figure), then it can be judged that the meridians are also parallel, but it is clear that the earth is one.

Sphere. So give each.

The line is finished. In order to.

Radian. Then the meridians intersect at the poles.

The meridians are not parallel.

There are many types of geographic views, including the main view (side view), the area view, and the polar top view. The main view is half of the entire globe that you normally see, and the top view of the polar region is a downward view from the polar sky, both of which are seen at the intersection of meridians and at the poles. And the area view, similar to the area map, you see the meridians are mostly parallel, but if you look closely, you will see that they are not parallel.

On a regular map, the view of the low-latitude region is relative to the high-latitude area.

, the meridians are relatively parallel. But if you take out a small area, the meridians can be drawn parallel (not including the pole area). For example, the earth is far away, but you don't find that the road you are walking is uneven, which is a truth.

If the earth is a piece of paper (a flat figure), then it can be judged that the meridians are also parallel, but it is clear that the earth is a sphere, so give each line an arc, then the meridians intersect at the poles.

A meridian, also known as a meridian, is defined as a semicircular arc on a great circle on the Earth's surface connecting the north and south poles. Any two meridians of equal length intersect at the north and south poles. So the meridians are not parallel.

If the meridian connects the north and south poles, it will intersect with the North Pole to the north and the South Pole to the south. So it's not parallel.

The meridians are all arcs and cannot be parallel.

The following statement of warp and weft is correct: choose a that any two parallels are parallel to each other.

aAny two parallels are parallel to each other; b. Any two meridians are parallel to each other.

Any two parallels are parallel to each other; Any two meridians intersect at the north and south poles.

The weft coils are parallel to the equator, so any 2 parallels are parallel.

The warp coil is a great circle that passes through 2 poles, so if the meridian has an intersection point, it is 2 poles.

So choose A

All the meridians will intersect at the north and south poles, so the description is wrong and does not fit the topic;

When the meridian and the weft intersect, they are perpendicular, so the description is wrong and does not conform to the meaning of the title;

All the meridians indicate the north-south direction, and the description is correct and in line with the topic;

All the meridians are of equal length, the description is correct, and it is in line with the meaning of the topic Therefore, the annihilation talks about the selection: the stupid c

All the meridians will intersect at the north and south poles, the meridians and latitudes are perpendicular to each other, the meridians indicate the north-south direction, all the meridians are of equal length, the option ABC is incorrect, and it does not fit the topic

Therefore, d
