Our heart, when we are resting, beats 60 to 100 times in a minute.

But besides hearts, there are many other things that pulse: the colors we see and the voices we hear for example are made possible by different frequencies of waves (pulsations) of light or sound waves.

A study published in the journal Geoscience Frontiers reveals that even the Earth itself has pluses. The Earth's pulse has a "beat" every 27.5 million years.

This is the rate at which major geological phenomena occur.

According to the study's lead author and geologist Michael Rampino from the Department of Biology at New York University, major geological events are random over time.

But the study, he adds, provides statistical evidence for a common cycle, suggesting that these geologic events are correlated rather than random.

The study authors compiled the latest dates for known geological phenomena over the past 260 million years:

- 29 sea level fluctuations

- 12 marine disappearances

- 9 disappearances on earth

- 10 periods of low ocean oxygenation

- 13 massive floods and catastrophic volcanic eruptions

- 8 changes in the rate of sea spreading

- 8 times there have been global pulsations in the magmatism between the plates

The dates gave scientists a new calendar of Earth's geological history.

Combining all the natural events, the scientists performed a series of statistical analyzes that revealed that these phenomena tend to cluster around 10 different dates, with peak activity occurring every 27.5 million years.

Between the ten busy periods, the number of phenomena dropped sharply, approaching zero.
