What is Earth's Rotation Day? History,  Significance and More

Earth's Rotation Day Every year, January 8 is recognised as Earth’s Rotation Day. 

On this day in 1851, French physicist Leon Foucault proved that the Earth revolves on its axis, which was a major breakthrough in the world of science and geography

History of Earth's Rotation Day The Greeks made the claim that the earth rotated on its own back in 470 BC.

Several experiments were also conducted to prove this but nothing concrete came out until 1851 when Foucault used a pendulum to demonstrate the earth’s rotation about a fixed axis

Significance Behind Earth's Rotation Day The goal is to celebrate the phenomena as well as learn more about Foucault’s well-known experiment. 

Children all throughout the world are motivated to learn about this phenomenon in detail. Some teachers even demonstrate Foucault’s experiment to children.

Rotation of Earth Earth rotates on its axis from west to east, and the Sun and the Moon appear to move from east to west across the sky. The spinning of the Earth around its axis is called ‘rotation’. One rotation of Earth completes one day, that is 24 hours. 

Importance of Earth's Rotation The Earth’s rotation creates the diurnal cycle of lightness and darkness and is also a reason for changes in temperature and humidity from time to time. It also causes tides in the oceans and seas.
