Have you ever wondered about the question, “What is the rotation speed of Earth?”

If so, then you will be glad to know that the answer can be found in the latest issue of the American Geophysical Journal. A new study published in the journal found that the spin rate of the Earth is indeed faster than previously thought.

In case you are unaware, the last time we had a gravitational pull on the Earth, it resulted in massive ice cores. These solid layers of ice were blasted off from the Earth’s surface. Scientists believe that some of this solid mass was left behind as the Earth sped up its spin. The latest research helps shed light on the interior structure of this planet.

How fast does Earth rotate? To answer this question, let us look into how the Earth obtains its rotation. According to the National Institute of Polar Research (NIPR), the tilt and velocity of the spin axis of the earth can be studied using satellites.
