Researchers have penned a new study in Geoscience Frontiers, and according to an analysis on 89 major geological events that have happened in the past 260 million years, most major geological events occur in intervals of 27.5 million years. So, what is a major geological event? The researchers took into account events such as extinctions, ocean anoxic events, rising sea levels, large volcanic activity, and Earth's tectonic plates shifting.

Lead author Michael Rampino, a professor in the departments of biology and environmental studies at New York University, said that the estimates aren't "exact", but it's a "pretty good estimate" that's "unlikely to be a coincidence". So, why every 27.5 million years does Earth have this geological "pulse"? The authors state in the study that the geological pulse may have something to do with the tectonic plates shifting and movement inside the mantle. The researchers also state that it could have something to do with the movement of Earth within our solar system/galaxy.
