Detailed explanation-1: -The Foucault pendulum and the Coriolis effect both provide evidence of earth rotation. Explanation: Coriolis is a force introduced in Physics that is applied on such objects that are in motion being in some frame of reference which rotates accordingly with inertial frame.

Detailed explanation-2: -The Foucault pendulum and the Coriolis Effect provide evidence of Earth’s rotation. Seasonal changes in the apparent positions of constellations provide evidence of Earth’s revolution.

Detailed explanation-3: -At the north or south pole, the pendulum is moving in a fixed plane (if we disregard the fact that the Earth is also revolving through space), so the plane of the pendulum seems to rotate through 360° as the Earth makes one full rotation.

Detailed explanation-4: -The South Pole goes into the ground and the North Pole comes out of it. Because of the Coriolis force, the bob of a pendulum in the Northern Hemisphere moves a little to the right in each swing. Over a period of time, the plane of swing is observed to have rotated, in the clockwise direction.

Detailed explanation-5: -Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere. This deflection is called the Coriolis effect.
