How the Moon’s slow drift is impacting our days and unveiling ancient secrets
Moon's impact on Earth is changing due to this slow change. It has been discovered by scientists that this drift is beginning to impact our day length rather than being a distant concern, as per the reports of Microsoft Start News.

Impact on day length
The duration of Earth's days is slowly but distinctly impacted by the Moon's orbit around the planet. This process lengthens the day by millions of years. To determine how the Moon's drift has affected Earth's rotation during the previous 1.4 billion years, researchers at the University of Wisconsin-Madison studied ancient rock formations that date back 90 million years.
According to their data, the Moon is moving away from Earth at a speed of 3.82 centimeters per year. In roughly 200 million years, if current trends hold, Earth's days may grow to include 25 hours.
As per the reports of Microsoft Start News, professor of geoscience at the University of Wisconsin-Madison Stephen Meyers compared the Earth-Moon system to a figure skater who slows as they extend their arms. This comparison shows how the Earth's rotation slows with increasing Moon distance. With the help of astrochronology, Meyers and colleagues hope to reconstruct ancient geological time scales, enabling the study of ancient rocks using techniques akin to those used in contemporary geological processes.
