The Earth's rotation is constantly slowing down, and the current sidereal day (the interval between the Earth passing through its upper midheaven twice in succession relative to a star, as opposed to the 24-hour solar day) is 23:56 minutes and seconds. So every once in a while, watches around the world are adjusted, most recently on December 31, 2005, when the world's clocks were uniformly added by one second.
There are the following reasons that affect the Earth's rotation cycle:
Tidal forces: The tidal forces of the sun and moon on the earth cause the earth to transform slowly. Slows down the Earth's rotation period by milliseconds about every 100 years. There is evidence that 400 million years ago in the Devonian period, the year of the Earth was 400 days.
Seasonal changes: There are annual changes and semi-annual changes. The annual variation is caused by seasonal changes in atmospheric flow (wind) with an amplitude of 20-25 milliseconds; The semi-annual variation is caused by the tidal action of tidal forces on the atmosphere, with an amplitude of about 9 milliseconds.
Irregular change: the exchange of matter or energy outside and within the earth. For example, the impact of a meteorite on the Earth will make the Earth rotate faster or slower depending on the direction and speed of the impact.
**Usually accelerates the Earth's rotation. In 2004, for example, the Indian Ocean sped up the Earth's rotation by about 3 microseconds.
If you change the rotation cycle of the earth as slowly as above, it will not affect the earth's ecosystem. But if a huge force is acting on the Earth so quickly that the Earth's rotation speed changes dramatically (e.g., a huge asteroid hits the Earth), the inertia of the atmosphere and oceans alone will cause hurricanes and tsunamis to blow on Earth. It can be devastating to the ecosystem.
Of course, this is almost unlikely, and this kind of thing will only happen during the "heavy bombing period" when the solar system is just formed, when the orbits of the various celestial bodies in the solar system are not yet stable and collisions are inevitable. The birth of the Moon is most likely due to the impact of a planet the size of Mars on the Earth.

The alternation between day and night time becomes longer, which may affect work and rest time and working hours
-
It has a great impact on the changes in the lives of animals, plants, and humans. The rest of humanity gets chaotic. plants and long periods of lack of sunlight. Absorbs light. It wilts easily.
-
The sea moved towards high latitudes, and the global tsunami became more and more violent the closer it was two levels, and the polar countries were flooded.
-
The atmosphere also moves, global temperatures warm, the temperature difference between day and night widens, and radiation increases at low latitudes.
-
The four seasons change slowly, and all kinds of animals and plants may not adapt or lose their regularity, thus affecting human beings
-
Time slows down, and human physiological systems become disrupted.
-
Geosynchronous satellites have been affected, GPS has failed, air crashes have increased dramatically, and some animals and plants have been unable to adapt to climate change and have died one after another;
-
Slowing down time has a great impact on a person's menstrual cycle, and systemic disorders may occur.
-
The menstrual cycle of all living things is disrupted by time.
-
There is no effect and may accelerate aging.
-
The speed of the earth's rotation has a very big impact on our lives, because the earth's rotation has a certain stability, if the earth's rotation is too fast, the time of the day will become very small, people will not be able to carry out normal life, human life will gradually shorten, and the living environment will be changed accordingly.
-
It can cause a variety of natural disasters. It will pollute our ecological environment. It will make our seasons shorter. will leave us with no temperature changes. It will shorten our lifespan.

In 2023, there will be some changes in the Earth's orbit. In 2033, due to the influence of human beings and other aspects, the ice and snow will melt, and the world's sea level will continue to rise
Earths orbit refers to the path of the earth around the sun, which is generally an ellipse with a small eccentricity, and its semi-major axis (a) kilometers; Semi-minor axis (b) km; Half focal length (c) 25 105 km; Circumference (l) km. The eccentricity (e) and flattening (f) of the Earth's elliptical orbit are (1 60 or and 1, respectively, and the Sun is located at one of the focal points of the ellipse. The distance from the Earth to the Sun varies between kilometers, with an average distance of kilometers.
The plane of the Earth's orbit is the ecliptic plane.

It's jet lag...
As the earth rotates, the sun rises in the east and sets in the west during the day, and the sun passes through the highest point in the sky at 12 o'clock in this place, so there are different places on different meridians. The same time used in the same time zone is regional time (local time on the ** meridian of the region) and the same time used worldwide is universal time (local time on the 0th meridian). The longitude varies by one hour every 15 degrees in regional time and every 4 minutes in local time and longitude every 1 degree. >>>More
Its name is "crosshatching" and it serves two purposes: first, accurate drawing, and second, correct reading and use. The profile is a "cross-section", and the topographic profile is equivalent to "cut a certain part of the earth along a line and look at its cross-section" (the topographic map is the topographic picture "seen in the sky", and the topographic profile is the topographic picture "seen from the side") This line is "taken down" from the topographic map, it intersects the contour line on the topographic map, and when the line is removed, it also takes "the altitude of each place on the line", and the profile is only "taken down in a straight line" The point heights are rearranged according to their height and order. >>>More
