Excuse me, why does the globe tilt 23 5 angles?

The angle between the equatorial plane and the Earth's orbital plane (yellow-equatorial angle) is.

The orbital plane is generally seen as horizontal, so the Earth appears tilted.

It should be to facilitate learning and teaching, and make the globe like this.

Because the Earth's axis is tilted relative to the plane of its motion around the Sun, approximately degrees, the globe must be tilted in order to coincide with reality.

Because the earth itself is tilted, the globe.

This is also made to conform to the reality and facilitate people's understanding of geographical knowledge. There is an angle between the Earth's orbit and the Earth's orbit, and this angle is calledYellow and red cornersIt has important astronomical and geographical significance, and is also the fundamental reason for the division of the four seasons and five zones on the earth.

1. The existence of the yellow-red angle refers to the rotation of the earth.

The angle of intersection of the orbital plane with the equatorial plane. Its specific value is 23°26', approximately equal to. It is precisely because of the existence of the yellow-red angle that the sun shines directly at the point.

At the latitude of 23 ° 26 north and south of the earth'to and fro, thus causing the height of the sun.

The seasonal changes and the length of days and the shortness of nights occur regularly, resulting in the four seasons and the cold and warm of spring and autumn on the earth. Precisely because ofThe rotation of the EarthThe angle of the orbit and the orbit are not the same, so there is a change of seasons.

2. The Rotation of the EarthWe know that the Earth not only rotates, but also rotates. The Earth rotates from west to east along its axis of rotation, which is called rotation. When viewed from the North Pole, the rotation appears counterclockwise, and from the South Pole, it becomes clockwise.

status. The Earth's axis of rotation is perpendicular to the equatorial plane, and the linear velocity of the rotation.

for 465 m sec. It takes 23 hours and 56 minutes for the Earth to rotate around in one cycle, which is what we call a day every day. It is precisely because of the rotation of the earth that we see the sun rise in the east and set in the west, and there will be a change in morning and dusk.

3. The Revolution of the EarthIn addition to its rotation, the Earth will also rotate around its orbit. The time it takes for the earth to revolve around is one year. It is because of the rotation of the earth that our seasons change.

The length of the days and the length of the nights and the height of the sun change periodically depending on the season. Depending on the position of the Earth during the year, it receives different amounts of light, so there will be a change of seasons and an alternation of cold and warm.

It is precisely because of the rotation and revolution of the earth that we have the alternation of morning and dusk and the alternation of seasons. Dear readers, do you understand now?

Because the globe is made according to the reduction of the earth by a certain proportion, and because of the rotation and revolution of the earth, there is a certain angle between the ecliptic plane and the equatorial plane, and this angle is the degree.

Because the earth does not rotate upright in the universe, the angle between its ecliptic plane and the equatorial plane is degrees, so the tilted globe is the true state of the earth in the universe.

Because the earth itself is tilted at this angle, the globe will also be tilted at this angle.

1. Because the tilt angle of the earth's rotation is degrees, the angle of yellow-red intersection is 23°26, and the tilt angle between the earth's axis and the ecliptic plane is 66°34, so the globe should also be tilted. This angle is also called the yellow-red angle, and the earth's rotation and revolution are inclined under the influence of the yellow-red angle. Therefore, the space posture of the earth is more realistically reflected, so the globe made is inclination.

2. Due to the existence of the yellow-red angle, the annual change of the direct point of the sun moving back and forth between the north and south latitudes of the earth is 23°26, which causes the seasonal change of the height of the sun at noon and the seasonal change of the length of day and night, resulting in the seasonal change of the amount of solar energy obtained by the yellow-red angle on the earth and the various places in Zhongqili, so as to form the replacement of the four seasons.

Because there is a yellow-red angle between the earth's orbital plane and the earth's orbital plane and the earth's orbital plane and the equatorial plane, the angle is the degree, that is, the latitude of the Tropic of Cancer. The Earth rotates and revolves obliquely, with the northern end of the Earth's axis pointing to the North Star. Therefore, the globe is made according to the posture of the actual earth when it rotates and revolutions.

The world's first globe was made by Mercator, a Dutchman who was a famous cartographer in the 16th century, who knew astronomy and geography and was good at mathematics. In fact, he began the first map as early as 1537, and later began to draw maps of Flanders.

In 1540, Mercator began to officially open his own cartography shop in the area of Louvain, and the precise proportions of the maps attracted a lot of attention from the people of the time, and in the same year he succeeded in producing a globe. In 1568, he successfully completed the world-famous "Floor Plan of the World".

1.The latitude and longitude grid globe has only the latitude and longitude grid and the annotation of the degree on its spherical surface, which is also called the theodolite.

2.A political globe is a globe with a smooth spherical surface that represents the division of administrative regions.

3.The terrain is a model that represents the terrain, and the spherical surface can be divided into two types: plane and three-dimensional uplift.

4.Schematic globes, spheres only show the distribution of continents and oceans, and are commonly found in decorative objects.

5.Teaching globes for teaching geography in schools and at home.

6.Craft gift globe, often used in home and office ornament decoration.

7.Large-scale display globe is often used in large-scale exhibitions to display chaincode, teaching observation and demonstration, etc.

Hello, because the tilt angle of the earth's rotation is degrees, the vertical yellow and red intersection angle of land objects is 23 ° 26, and the tilt angle of the earth's axis and the ecliptic plane is 66 ° 34, so the globe should also be tilted. This angle is also called the yellow-red angle, and under the influence of the yellow-red angle, the earth's rotation and revolution are tilted, so in order to more truly reflect the attitude of the earth in the morning, the globe made is inclination.

The tilt of the globe is because the axis of rotation of the earth and the plane of the orbit of the earth are tilted at an angle, and this angle is the degree.

Because of the influence of the yellow-red angle, the rotation and revolution of the earth are tilted, so in order to reflect the earth's moving attitude more realistically, the globes made are relatively inclined. It is precisely because of the yellow-red angle that the annual change of the direct sun point moving back and forth between the north and south latitudes of the earth is 23°26, which causes the seasonal change of the noon solar height and the seasonal change of the length of day and night, which causes the seasonal change of the yellow-red angle of the earth and the amount of solar energy obtained in various places, forming the replacement of the four seasons.

The yellow-equatorial angle refers to the angle of intersection between the earth's orbital plane (ecliptic plane) and the equatorial plane (celestial equatorial plane), also known as the solar declination angle or the equatorial elongation. The angle of the Earth's rpm around the Sun is about 23°26'。The existence of the Yellow Junction has important astronomical and geographical significance, and it is the fundamental reason for the change of the four seasons and the distinction of the five zones on the earth.

The structure of the globe

The globe consists of a base, a fixed frame, a sphere, and an axis of the earth. There are various symbols, words, and colors on the globe to represent land, rivers and lakes, oceans, mountains, cities, etc. There are also longitudes, latitudes, north and south poles; The globe rotates around the Earth's axis, pointing near the North Star, an imaginary axis that intersects the sphere at the North Pole and the South Pole.

In order to make it easier to understand the earth, people imitated the shape of the earth and reduced it according to a certain scale to make a model globe of the earth. The deformation of length, area, direction, and shape on the globe is correct, so it is correct to observe the interrelationship of various scenery from the globe.

The reason why the globe is inclined is because this angle determines the angle between the Earth's axis of rotation and its orbit. This angle is known as the Earth's axis inclination and is formed by the balance between the centrifugal force and the gravitational force generated by the Earth's rotation.

The existence of the Earth's axis inclination causes the Earth's seasons to change. As the Earth revolves around the Sun, different regions of the Sun shine at different angles, resulting in different climates and seasons. On the globe, the inclination can more realistically reflect the tilt of the earth's axis of rotation and the orbit of the earth, so that users can better understand the geographical and climatic characteristics of the earth.

This angle of inclination is also known as the trapped-yellow econjunction, because it is the angle between the ecliptic and the equator. The ecliptic is the trajectory of the Sun moving in the sky as the Earth sees the Earth rise and fall, while the equator is the virtual line that divides the Earth into north and south halves. Changes in the yellow-red angle also affect the Earth's climate and seasonal changes.

A: The tilt of the globe is caused by the actual posture of the Earth during its rotation and revolution. There is a yellow-red angle between the earth's orbital plane and the earth's rotation orbital plane, and the yellow-red angle is the yellow-red intersection angle, which is a degree, and the latitude of the Tropic of Cancer is also a degree.

Therefore, in order to more realistically reflect the spatial attitude of the earth, the globes made are inclined to the horizontal plane. Affected by the intersection of yellow and red, the rotation and revolution of the earth are tilted, which is also the reason for the change of seasons and the length of day and night.
