in Earth Day rotation should be explain

Answer:
Earth's Rotation and the Apparent Daily Motion of the Sky
The earth rotates about an imaginary line that passes through the North and South Poles of the planet. This line is called the axis of rotation. Earth rotates about this axis once each day (approximately 24 hours).
Explanation:
January 8 is Earth’s Rotation Day. The day commemorates when French Physicist, Leon Foucault, demonstrated the Earth rotates on its axis in 1851.

The Earth's axis is tilted about 23.5° with respect to its orbital plane around the Sun.

To prove his theory, Foucault suspended a lead-filled brass sphere, now called the Foucault Pendulum from the top of the Pantheon in Paris.
He showed that the plane of the swing of the pendulum rotated relative to the Earth’s rotation. You can now see the Foucault Pendulum demonstrating the rotation of the Earth in science museums around the world.
