Is the warp as long as the weft and why

No. The meridian, also known as the meridian, is an auxiliary line hypothesized by human beings for the convenience of measurement, and is defined as a semicircular arc on the great circle line connecting the north and south poles on the earth's surface. 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 20037km, but the length of each meridian is slightly different.

It is also called "weft coil".

A circle perpendicular to the Earth's axis and orbiting the Earth. The equator is the largest weft coil.

The center of the coil is located on the earth's axis; The parallels indicate the east-west direction; On Earth, the parallels are perpendicular to the meridians; The equatorial latitude coil is the longest. The weft coils at the poles are condensed into one point. The length of the parallels is different, each parallels are a circle, and the parallels are divided into southern and northern latitudes.

Not the same length, the warp threads are all the same length, and the weft threads are long and short. Find yourself a globe and take a look!

The warp and weft are all imaginary threads. Like a winding ball, the meridian is longitudinal (always through the axis of the earth, divergent) and the weft is horizontal (always horizontal).

The warp threads are basically the same, with small differences, and there is not much difference.

The latitude equator is the longest (because the Earth is an ellipsoid). , decreasing to the poles, and finally shrinking to one point.

Not the same, because all the warp threads are equal in length, while all the weft threads are not equal. [Can't compare!] ]

The length of the weft varies and there is no specific length, the length of the warp is 20037km.

1. Weft: The weft is a circle of unequal length, and the longest weft coil - the equator, is called the 0° parallel. The latitude measured north from the equator is called the north latitude, and the south latitude is called the south latitude. The north and south latitudes are 90° north, the North Pole is 90° north latitude, and the South Pole is 90° south latitude.

2. Warp: The semicircle in which the warp coil is divided by the two 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 numerical value, called longitude. The meridian indicates north and south.

The length of the meridian is the same, that is, it refers to half of the circumference of the earth, that is, 20,000 kilometers, and the length of the latitude can be large or small, the largest is the equator, 40,000 kilometers, and the smallest is the north and south poles, zero kilometers.

The length of the meridians is equal, 20,000 kilometers.

The longest equator in the parallels is 40,000 kilometers, and the length of the other parallels is the length of the equator multiplied by the cosine of that latitude.

The longest length of the weft is.

The length of the meridian is 20,037 km

The longitudes and longitudes on Earth are ultra-clear.

The meridian is the line connecting the north and south poles on the globe, which has the following characteristics: an equal length semicircle, intersecting the two poles, indicating the north and south;

The latitude line is a circle on a globe parallel to the equator and perpendicular to the meridian, with the following characteristics: unequal circles, parallel to each other, indicating things.

Latitude: 1. Equator: It is called the 0° parallel, which is the longest of all the parallels. The closer the parallels to the poles, the shorter; The closer you get to the equator, the longer the parallel.

2. Tropic of Cancer: 23°26 north latitude'The latitude is the Tropic of Cancer.

3. Tropic of Capricorn: 23°26 south latitude'The latitude is the Tropic of Capricorn.

4. Arctic Circle: 66°34 north latitude'The parallels are called the Arctic Circle.

5. Antarctic Circle: 66°34 south latitude'The parallels are called the Antarctic Circle.

Concept: The longitude and latitude lines 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 line connecting the north and south poles is called the meridian line.

The thread perpendicular to the warp is called the weft. The weft is a circle of varying lengths. The longest parallel is the equator.

Division: Because the meridian indicates the north-south direction, the meridian is also called the meridian. Internationally, the meridian that passes through the original site of the Greenwich Observatory in the United Kingdom is called the 0° meridian, also known as the prime meridian.

On Earth, the meridian lines indicate the north-south direction, and the latitude lines indicate the east-west direction.

Lines are circles of varying lengths. Because the meridian indicates the north-south direction, the meridian is also called the meridian. Internationally, the meridian that passes through the original site of the Greenwich Observatory in London, England is called the 0° meridian, also known as the prime meridian.

The parallels indicate the east-west direction; 0° parallel, also known as the equator.

The equator is the largest weft coil. The meridians and parallels were drawn on globes and maps in order to determine the position and direction on the earth, and there were no latitude and longitude lines on the ground.

Longitude and longitude The large circle that passes through the poles and is perpendicular to the equator is called a meridian or meridian, also known as a meridian. Since all the meridians intersect the north and south poles and are perpendicular to the parallels, any meridian represents the north-south direction of the earth.

The longitude of a point on the earth is the angle between the plane of the meridian and the plane of the prime meridian where the point is located. This angle is equivalent to the angle at which the equatorial arc between these two planes stretches at the center of the earth. East of the prime meridian is called east longitude, which is represented by "e"; The west is called the west longitude, which is represented by "w".

The circumference of the earth is 360°, so the east and west meridians are 180°.

All circles on a sphere can be seen as being formed by a certain plane and a certain sphere, that is, the intersection of a certain plane and a certain sphere.

Geometrically, any circle represents a certain plane. The large circle formed by the plane of the earth's axis cut from the earth's surface is called a warp coil. This warp coil plane passes through the earth's axis and therefore also through the center and poles.

In the same sphere, with the center of the sphere as the center of the circle, they are all great circles, so the meridians are all great circles. Since all meridians pass through the poles of the earth, each meridian coil is divided into two semicircles of 180° by the north and south poles, which are called meridians or meridians.

The weft is different from the warp in that it is a circle and has a difference in size. The size of the weft coil is determined by the distance between its circle and the center of the earth. The closer the center of the weft coil is to the center of the earth, the larger the weft coil is, and vice versa, the smaller it is.

Therefore, the weft coil centered on the center of the earth is the largest weft coil and is called the equator; And the farthest coil of latitude from the center of the earth are the north and south poles.

On the earth's surface, there are infinite lines of longitude and latitude. Any point on the earth's surface has its own meridians and parallels, that is, every point is the intersection of meridians and parallels. From the point of view of the relationship between the two, the meridian and the latitude are perpendicular to each other, because the relationship between the plane passing through the earth's axis and the plane perpendicular to the earth's axis is perpendicular to each other.

The meridians all represent the north-south direction, and since the meridians converge at the South Pole and the North Pole, the north-south direction is the meeting direction and is a limited direction. The parallels represent the east-west direction, east is the direction of the earth's rotation along the parallel, and west is the opposite direction of the earth's rotation along the parallel. So, the east-west direction is the circular direction (or the direction of rotation), which is an infinite direction.
