# How fast does the earth spin

How fast does the earth spin? 1000 miles per hour (1600 km/hr.) is the rate at which the earth spin.

Do you think that the everyday 24 hours is exact the same? You think that your watch is telling you everything but it is not.  There are forces altering the velocity of the rotation of the Earth. The effect is so small that it is hard to notice. The gravitation forces cause tides by the gravitational forces amid the Earth and from the outer space, the moon, sun etc. causes drag force as they interrelate with this planet. That tidal friction is an additional 2.3 milliseconds to each day.  Meteorological conditions structures can alter the Earth’s spin, with airstreams smearing a decelerating force to Earth’s surface. Lastly, earthquakes can muddle with the span of a single day by essentially reallocating the planet’s mass. For example, earthquake that hit Japan during 2011 in fact fast-tracked the Earth’s rotation (since it lifted the mass on the way to the center of the Earth) and reduced the 24 hours by 1.8 microseconds.

This planet is spinning on its axis one time for each 24 hours. In the center of the Earth, the rate of Earth’s spin is aroun1,000 miles per hour (1,600 km/h). Each day consists of 24 hours and we all experience day and night on regular routine but we never notice the spin or the rotation. We do not understand the spin since everything on the planet like humans, atmosphere and Earth’s oceans are circling laterally with the Earth at the identical continual rate.
