The Equator is an imaginary line that divides the Earth into the Northern and Southern Hemispheres. It is the longest line of latitude and has a circumference of approximately 40,000 kilometers. The Earth rotates around its axis, causing day and night, and this rotation creates the velocity of rotation.
The velocity of rotation is directly related to the circumference of the Earth. The Earth completes one full rotation in approximately 24 hours. This means that the velocity of rotation at the Equator is 40,000 kilometers per 24 hours, or roughly 1,666.67 kilometers per hour.
The velocity of rotation at the Pole, however, is different. As the Pole is located at the axis of rotation, it does not have any circular movement. The rotation occurs in a spinning motion, creating the velocity of rotation. Therefore, the velocity of rotation at the Pole is zero.
Therefore, option 1 "Zero" is correct because the velocity of rotation at the Pole is indeed zero. The poles do not experience any rotational motion, unlike the Equator.
