प्रश्न
Give reasons for the following
The speed of the rotation of the earth is greater at the Equator than at the Arctic Circle.
उत्तर
As every part of the earth takes a frill round within 24 hours, the equator being the largest circle of latitude 0°, the speed is greatest at the equator due to crossing the maximum distance per hour. i.e. it is 1660 km per hour, while it decreases to 0° at poles.
