Researchers have found evidence that competing forces deep within Earth’s interior are causing subtle variations in the planet’s rotation. According to the study, movements in Earth’s core create a gravitational tug-of-war that slightly alters the length of a day.
Although these changes are extremely small, they provide important clues about the dynamic processes occurring beneath Earth’s surface. Understanding such variations could improve long-term models of planetary behavior and geophysical activity.
Scientists emphasize that the discovery highlights how deeply connected Earth’s internal structure is to observable phenomena on the planet’s surface
