The speed of earth’s rotation decrease towards the_________________
a. Equator
b. Poles
c. Sector
d. None of these

Hint: The earth’s rotation refers to the rotation of the planet earth around its own axis. The earth rotates in an eastward direction and if viewed from the North Pole star Polaris, the earth turns counterclockwise.

Complete answer:
The North Pole is the point in the Northern Hemisphere where the earth’s axis of rotation meets its surface. The South Pole on the other hand is the other point where the earth’s axis of rotation shifts its surface towards Antarctica.
The earth as a whole rotates 360 degrees once in about 24 hours with respect to the Sun. The surface speed of the earth’s rotation at the top is known as the geographic North Pole. The North Pole is slower than the vast majority of other places on the planet but it is equal to that of the other terrestrial location.
As far as the rotation of the earth is concerned, the earth rotates faster at the equator and decreases towards the poles at the top and bottom with the rotation speed at the middle latitudes falling somewhere in between these two extremes.
The speed of a person living on the equator is faster because the person covers more distance in the same span of time. On the other hand, the speed of a person located in the North Pole is zero because he has no distance to cover. Likewise, in the South Pole, the speed of a person will also remain zero.
So, the correct answer is Option B

Note: The rotation of the earth is directly accountable for the appearance of the sun rising in the east and the sun setting in the west. The North Pole and the South Pole are essentially two fixed points through which the planet earth spins on.
