Does the Earth increase by 70 seconds every year?

No, the time will not increase.

As described upstairs.

The so-called year is the time for the earth to rotate one week, one day is the time for the earth to rotate for one week, when the time of rotation of a week of hole change is gradually extended and the time of rotation will not change, the number of rotations corresponding to a natural revolution will be less, that is, the number of days in a year will be less, the number you said should be the result of the calculation, the landlord may wish to calculate how many days in 200 million years, multiplied by the second + the length of a day now is equal to the length of a day after 200 million years, Now the so-called day year is converted into a day divided by 200 million, and the length of a day after the year will be roughly equal to 250 ( Sen Trembling Shed.

Lying on the couch with a cup of coffee, savor the extra second.

If a second is a year, the earth will change dramatically. Here are some of the things that can happen:

1.The length of the day will become 60 seconds. This will result in shorter sunrise and sunset times, and more drastic changes in weather and climate.

2.The rotation speed of the earth will increase, causing objects on the earth to move faster. This can have an impact on animal behavior, plant growth, and human daily life.

3.The length of a year will become 365 60 = 21960 seconds. This will lead to more extreme changes in the seasons, such as summer may be hotter and winter may be colder.

4.Physical phenomena on Earth, such as volcanic eruptions, and hurricanes, will become more frequent and intense.

In short, if a second is a year, the earth will undergo tremendous changes, and these changes will have a profound impact on life and the natural environment.

Due to the fluctuations in the rate of rotation of the Earth, in the 50s of the 20th century, the international standard second was defined by the average length of the regression year. 1 second is equal to 31 556 925 in 1 yearOne in 9747, or 86,400 seconds in 1 day, 1 year in days.

In order to reproduce this standard, it is necessary to make long-term tedious astronomical observations, and the accuracy can only reach 1 10 The International Committee on Weights and Measures passed a proposal stipulating that the second is defined by the ultrafine energy level difference of the ground state of the 133-cs atom, and this is achieved by atomic clocks. Today, atomic clocks used for metrology have reached an accuracy of 1 10 14, in other words, an error of 1 second every 3 million years.

The original purpose of the calendar was to "count the days as you live", and not to miscalculate the days. According to today's atomic clocks, people have already reached the level of "one second counts one second". And, in turn, the unevenness of the Earth's rotation rate can be measured with an atomic clock.

Measurements in recent years indicate that the actual day length is 86,400 seconds , which is between 1ms and 3ms. In order to correct the accumulated errors, the International Time Bureau in Paris, every .

In a year or two, the world's "standard clock" will be ordered: a "leap second" will be added.

It seems, probably, should, be to go around for a week, meow.
