How to get to the axis center of DNF
On the symmetrical point of the earth's axis: the latitude does not change; The sum of longitudes is 180 degrees, east longitude to west longitude. For example, 20 degrees north latitude and 20 degrees east longitude, the symmetrical point is 20 degrees north latitude and 160 degrees west longitude
about the symmetry point of geocenter: the number of latitudes is the same, and the north latitude is opposite to the south latitude; The sum of longitudes is 180 degrees, east longitude to west longitude. For example, 20 degrees north latitude, 20 degrees east longitude, 20 degrees south latitude and 160 degrees west longitude
for the symmetric point of the equator: the number of latitudes is the same, and the north latitude is opposite to the south latitude; Longitude does not change. For example, 20 degrees north latitude and 20 degrees east longitude, the symmetrical point is 20 degrees south latitude and 20 degrees east longitude
extended data:
the earth's axis is at the time point of the spring and autumn equinox, and the orientation direction of the earth's axis and the ecliptic plane is 90 degrees to each other, and at a point perpendicular to the ecliptic plane; At the time point of the second Solstice of summer and winter, the orientation of the earth's axis and the ecliptic plane is also 90 degrees to each other, and tilts to a point of the ecliptic, with an angle of plus or minus 23.26 degrees
at the equator, animals and plants grow faster, larger and more bizarre than those in other places. Sunlight in the equatorial region is the most powerful energy on earth. Because the sun here evaporates a lot of the ocean, the impact will form a humidity column in such a large area, and then form wind and undercurrent, which will eventually provide energy for life in extremely remote places
In terms of mass, the core accounts for 16% of the total mass of the earth, the mantle accounts for 83%, and the crust, which is most closely related to people, accounts for only 1%. The core of the earth is located in the innermost part of the earth. It has a radius of about 3470 km and high density, with an average weight of 12 grams per cubic centimeter. The temperature is very high, about 4000 ~ 6000 ℃. It can be further divided into kernel and outer kernel According to the transmission of seismic wave, the outer core is melted. It is inferred from the iron meteorites from the cores of other planets that the earth's core is also composed of iron and nickel. The self excited motor theory of the earth's magnetic field also needs the existence of a liquid metal outer core. As for the core, it is very likely to be solid iron< br />if you take a basketball and let it rotate on the ground, almost all places on the surface of the basketball are moving,
but there are always two points that do not move. Connecting these two points is the ball axis, and the ball axis is variable
similarly,
because the earth is rotating, it has an axis! And it's changeable
the position of the earth's axis in the earth is not fixed, but there is a slight movement, resulting in the "polar shift"
the earth's axis is the "axis" of man's illusion
get it!
2. Climate change. All kinds of weather on the earth basically come from the sun. If the angle of the earth's axis changes, the climate of the whole earth will change.
if the earth's axis changes greatly, All of our creatures will die or evolve because they can't adapt to the new climate
24 hours
earth axis
tilt
I don't know what kind of type you're talking about.
if you just change the angle,
then the positions of the geographical North and south poles will change (I don't know if the magnetic north and south poles will change, so I won't say yet)
and another type is that the earth's axis is also rotating
but the problem is that the earth's axis itself is rotating with the sun The third one is that the earth axis moves irregularly
then what happens is Dole
maybe (this word keeps the accuracy of the expository language
I don't know if it will really be like this) what changes with it is the calendar
that is, the change of month, year and day
the length of day and night is irregular
and it will cause tide The irregular change of Xi's
should be that the life of animals is regular
so most animals can't adapt to it
and die
if the magnetic south and North Pole doesn't change
then the moon may collide with the earth or leave the Earth Moon system (guess
hit rate is 50%). If it changes
then the moon will not change (if it doesn't change
so will the tide
sorry
I'm just limited
my guess is not rigorous enough
but it's all based on physics
The reason for the tilt of the earth's axis: no matter where the earth is in orbit, its north pole always points near the Polaris, so does the South Pole. According to Newton's law of universal gravitation, there may be a star above or below it that attracts the earth's south pole or North Pole
at the time point of the equinox of spring and autumn, the orientation of the earth axis and the ecliptic plane is 90 degrees to each other and perpendicular to the ecliptic plane; At the time point of the second Solstice of summer and winter, the orientation of the earth's axis and the ecliptic plane is also 90 degrees to each other, and tilts to a point of the ecliptic, with an angle of plus or minus 23.26 degrees
extended data:
the earth's rotation is not as perfect as imagined, and its rotation axis has offset phenomenon, which is called "polar shift" in science
The measurement in the 20th century shows that the axis of rotation drifts about 4 inches (10 cm) a year, and the drift distance may reach more than 10 meters in a century. Based on the observation data and model-based analysis of the 20th century, NASA scientists have identified three broad geological causes of the polar shift: Greenland, glacier rebound and mantle convectionaccording to the geological data of the 20th century, the earth's rotation axis drifted at a distance of about 10 cm per year ring 1900-2000, and the drift distance reached 10 cm in the whole century. It is traditionally believed that this phenomenon is contributed by the rebound of glaciers, but new research suggests that there are two major geological processes jointly causing the "pole shift"
200 years ago, the celestial North Pole was close to the Polaris we see now, and the distance between them was only half a century ° Then, the North Pole graally leaves the present Polaris. In 8000 years, Tianjin IV of Cygnus will become the north star. In about 12000 years, it will move to just five miles from Vega ° At that time, Vega will become Polaris. After that, Tianbei continued to leave Vega slowly, and in another 12000 years, it returned to its present position.

1, the latitude does not change
2. The sum of longitudes is 180 degrees, one is east longitude, the other is west longitude
therefore,
the symmetrical points about the earth's axis of a point at 60 degrees north latitude and 20 degrees east longitude are 60 degrees north latitude and 160 degrees west longitude.
