It is said that the east and west longitude and the north and south latitudes, but why is it that on

It is called the east-west longitude, which is due to the change in the direction of longitude to the east-west direction, but the direction of the extension of the meridian is north-south, that is, the meridian is connected to the south pole and the north pole, if you go along the meridian, there are only two possibilities, either towards the north pole or towards the south pole. So the meridian indicates the north-south direction.

The plane of the weft coil is perpendicular to the earth's axis, and it goes in the direction of the parallel, either rotating with the earth.

The direction is the same or the other way around. The same direction as the rotation is east, and the opposite is west. So the parallels indicate the east-west direction. There are n parallel lines, bounded by the equator, which exactly divides the earth into two halves, half of which is the northern hemisphere.

Half is the Southern Hemisphere.

The latitude in the Northern Hemisphere is the northern latitude, while the latitude in the Southern Hemisphere is the southern latitude.

The answer to this question involves the shape of the earth and the definition of latitude and longitude.

First, the shape of the Earth can be likened to a slightly flattened sphere, due to the slight expansion at the Earth's equator and the slight compression at the poles. This shape makes it possible to locate any point on the planet in terms of latitude and longitude.

A meridian is a line that indicates a north-south direction. On Earth, all meridians converge at the north and south poles and are radially distributed from the North Pole. If we think of the Earth as a sphere, then the meridian is the line on the sphere that connects the North Pole and the South Pole.

Due to the shape of the Earth, all the meridians appear to converge towards the center from the North Pole to the South Pole, so the meridians indicate a north-south direction.

The weft line is the line that indicates the east-west direction. The latitude is bounded by the equator and is distributed radially to the southern and northern hemispheres. If we think of the Earth as a sphere, then the parallels are the lines on the sphere that are parallel along the equator.

Due to the shape of the Earth, all the parallels appear to be parallel from the equator to the poles, so the parallels indicate the east-west direction.

So, on graticules, the warp lines indicate north and south, and the latitude lines indicate east and west. This is determined by the shape of the earth and the definition of latitude and longitude.

The meridian line indicates the north-south direction, and the latitude line points to the east-west direction.

The meridian, also known as the "meridian", is a supplementary line that has been hypothesized by humans for the convenience of measurement, and is defined as a semicircle that connects the north and south poles and is perpendicular to the parallel. Everything on the earth that is formed by the plane of the earth's axis is cut off from the ground by the plane of the earth's axis is called a "warp coil". The semicircle in which the warp coil is divided by the poles is called the "warp".

The length of the meridian is about 20,037 km, and any two meridians are of equal length, intersecting at the north and south poles. Each meridian has its corresponding value, which is the longitude.

The size of the weft coil varies, the equator is the largest weft coil, and the weft coil gradually decreases from the equator to the poles, and the north and south poles are reduced to points. Meridians and parallels are drawn on globes and maps in order to determine the position and direction on the earth, and there are no latitude and longitude lines drawn on the ground. The warp and weft are perpendicular to each other.

The meridian guides the north, and the latitude points east-west.

1. Set the direction first: general orientation method - facing the map, up north and down south, left west and right east.

2. Determine the warp and weft: According to the concept of warp and weft, the warp indicates north and south, and the weft indicates east and west, so the up and down lines on the globe are the longitudes, and the left and right lines are the wefts.

3. Latitude and longitude determination method: if the value of longitude is getting larger and larger to the east, it is east longitude; If the value is larger and larger to the west, it is the west longitude. If the value of latitude is increasing to the north, it is the north latitude; If the value is larger and larger to the south, it is the southern latitude.

On graticules, the longitude indicates the north-south direction and the parallels indicate the east-west direction

Therefore, the answer is: Sutra; Weft

On a graticule map, what direction does the meridian indicate oh what direction does the latitude indicate should be:

On maps with graticules, the parallels indicate east-west and the meridians indicate north-south.

The meridian divides the earth longitudinally through the north and south poles, so each meridian is pointing north-south;

The parallels are parallel to the equator and divide the earth (perpendicular to the meridians), so each parallel is pointing east-west;

On a map with a network of meridians, the meridians point north-south and the latitude points east-west.

It is precisely because the meridian runs north-south.

So all the points on the same meridian are of the same degree.

Then, of course, the correspondence is that different meridians, the degree of things must be different.

Therefore, two different meridians opposite each other can represent the relative east-west relationship.

Now that we divide the earth vertically into two and divide it into the eastern and western hemispheres, then all the meridians are divided into two parts, one in the eastern hemisphere and the other in the western hemisphere (ignoring the two that happen to be on the dividing line).

This gives rise to the concept of the East and West Classics.

The same can be said for the question of northern and southern latitudes.

East-west longitude, north-south latitude. The meridian lines indicate east and west, and the latitude lines indicate north and south.
