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.
During pregnancy, Vitamin B12 is crucial for properly developing the fetus’s brain and nervous system. A deficiency of B12 in pregnant women can increase the risk of complications such as preterm birth and low birth weight.
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.
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.
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.
