FASTER As the world burns. Photo by Greg Rosenke. As the world turns Even though it’s over, 2020 is still getting worse. Case in point, scientists have discovered that, due to a variety of circumstances, the Earth apparently spun on its axis at an increased rate last year. Yes, our ...
Previous research had shown that the Earth's core rotates faster than the rest of the planet. However, scientists from the University of Cambridge have discovered that earlier estimates of 1 degree every year were inaccurate and that the core is actually moving much slower than previously believed...
Astronomers calculate a day in two ways. There’s the amount of time it takes for the Earth to complete one full rotation on its axis, compared to the background stars. Imagine you were looking down at the Earth from above the North Pole. You’d see the Earth turn once completely in ...
(Imagine a basketball spinning on your finger. A random point on the ball's equator has farther to go in a single spin as a point near your finger. Thus, the point on the equator is moving faster.) 5. The planet moves around the sun (Image credit: Getty Images) The Earth isn't ...
Earth's spin has a bit of a wobble to it, as the axis drifts at the poles. The spin has been drifting faster than normal since 2000, NASA has measured, moving 7 inches (17 cm) per year to the east. Scientists determined that it continued east instead of going back and forth because...

Four, the speed control of the earth's rotation Through analysis and research, the earth seems to be a wind wheel, blown by the atmosphere around the earth's axis, it will not because the inertia of the faster or faster, or uneven speed? This should be analyzed from the following ...
Our planet has been rotating faster of late. ©iStockphoto.com/joecicak Atomic Clocks Expose Earth's Irregular Speed The Earth is an excellent timekeeper: on average, with respect to the Sun, it rotates once every 86,400 seconds, which equals 24 hours, or one mean solar day. ...
,000 years ago, has also made Earth spin faster. Their weight squashed the poles; their subsequent disappearance allowed Earth's crust to rebound and become more spherical. This caused an acceleration in the planet's spin, an effect familiar to skaters tucking in their arms to rotate faster....
