What are the first geographical meridians, latitudes, Tropic of Cancer, and Tropic of Cancer

The line connecting the north and south poles is called the meridian line. The thread perpendicular to the warp is called the weft.

Since the meridians connect the north and south poles, all the meridians are equal in length and indicate the north-south direction. The parallels all indicate the east-west direction. The warp and weft threads are perpendicular to each other and intertwined with each other, forming a graticule.

When reading a map, you can use the graticule to determine the direction, and you can also determine the latitude and longitude position of any point on the earth.

The Tropic of Cancer is the latitude line where the direct point of the sun moves to the southernmost point when it moves to the south, and its latitude value is equal to the yellow-red angle, which is about 23 degrees 26 minutes south latitude.

The Tropic of Cancer is the farthest point from the equator that the Sun can reach directly in the Northern Hemisphere.

The Tropic of Cancer is the southern latitude, and the Tropic of Cancer is the northern latitude.

The Tropic of Cancer refers to the important parallels at the northern latitudes. On the summer solstice on June 21, the midday sun will shine directly on the Tropic of Capricorn, which is also the beginning of summer in the Northern Hemisphere and the beginning of winter in the Southern Hemisphere. The Tropic of Capricorn, on the other hand, is an important latitude at the southern latitudes.

On the winter solstice on December 21, the noon sun shines directly on the Tropic of Capricorn, which is the beginning of winter in the Northern Hemisphere and the beginning of summer in the Southern Hemisphere.

These two parallels had their own names as early as 2,000 years ago, because at that time, the summer solstice sun was in the constellation Cancer, so the Tropic of Cancer was also called the Tropic of Cancer; The winter solstice sun is in Capricorn because the Tropic of Cancer is also called Capricorn Tropic of Capricorn. Although the constellation of the Sun has changed at different times due to the precession of the equinox, the names of the two Tropic of Cancer are still in use today.

The dividing line of the Tropic of Capricorn

The Tropic of Cancer marks the Tropic of CancerThe Tropic of Cancer is the dividing line between the tropics and the temperate zones of the north and south. The area between the Tropic of Cancer and the Tropic of Capricorn is tropical, where the sun can shine directly and get the most heat; The area between the Tropic of Cancer and the Arctic Circle (66°34 N) is the North Temperate Zone, and the area between the Tropic of Capricorn and the Antarctic Circle (66°34 N) is the South Temperate Zone. In temperate regions, the sun can only shoot obliquely all year round, and the heat obtained is moderate.

Most of China is located in the north temperate zone and has a temperate climate.

Before 1985, the only symbol of the Tropic of Cancer on the Earth's surface was the "Tropic of Cancer" stele in Chiayi County, Taiwan Province, China, which indicated that the Tropic of Cancer passed from there. On July 15, 1985, China built another meter-high Tropic of Cancer marker tower in Conghua County, Guangdong Province.

The body of the tower is rocket-shaped, and there are arches in the east, west, south and north. The bottom of the tower is paved with marble, and the red agate is embedded in the middle dot to show the position of the direct sun. At the top is a copper ball with a diameter of 120 centimeters, and a round hole is opened in the middle of the ball for direct sunlight verification.

23°26 N, 23°26 S.

The Tropic of Capricorn is the farthest point the Sun can reach in the Southern Hemisphere, at about 23°26 south latitude, parallel to the line of latitude. Every year on the winter solstice, the direct point of the sun reaches its maximum latitude in the southern hemisphere, which is the height of summer in the southern hemisphere.

After that, the direct sunlight gradually moved northwards and kept moving in a cycle between the two circles of latitude near 23°26 N and 23°26 N.

Significance of the Tropic of Capricorn:

1. The rotation axis of the sphere is vertically inclined to the angle of the sphere around the orbital plane of the sun.

2. If the rotation axis of the ball is tilted, the ball revolves around the sun, and the area (latitude) of the direct ball of the sun in the elliptical period (period) is between the north-south return line.

3. Every June 22, the direct sunlight of the northward line moves southward, and on December 22, the direct southward line is close to the direct sun point (latitude), and the temperature is higher than its area.

4. The north-south return line changes the four seasons of the ball, so that the seasons of the northern and southern hemispheres are completely opposite.

Southern and northern latitudes.

The tropic of capricorn is the latitude line where the direct point of the sun moves to the southernmost point when it moves to the south, and its latitude value is equal to the angle of yellow and red cross, about 23 degrees 26 minutes south latitude. The Tropic of Cancer and the Tropic of Cancer are also the dividing lines between the southern temperate zone, the northern temperate zone and the tropics; The Antarctic Circle and the Arctic Circle are 90 degrees minus the Tropic of Capricorn, which is the dividing line between the southern temperate zone, the northern temperate zone, the southern cold zone, and the northern cold zone. As an important work of Henry Miller's autobiographical romance, the Tropic of Cancer mainly narrates and describes Henry Miller's early life experience in New York, as well as various feelings, associations, reveries and fantasies related to it.

Miller is in this work, which mainly depicts the inner spiritual world of the young man who writes about himself.

The tropic of cancer is the farthest point from the equator that the sun's rays can reach in the Northern Hemisphere. It is the maximum angle between the plane formed by the earth's revolution around the sun and the earth's equatorial plane, and it is also the angle of the angle of the yellow and red angles.
