The polar circumference of the Earth is 40,008 kilometers. What is the equatorial circumference?
The Force of Gravity:
Gravity is what holds the Earth and the other plants into spherical shapes. If the Earth were stationary in space it would likely be perfectly spherical, but the rotation of the Earth means that there are more forces involved than just that of gravity.
Answer and Explanation: 1
The equatorial circumference of the Earth is about 40,075 km (24,901 miles)
The earth bulges out at the equator, making the equatorial diameter of the Earth larger than the polar diameter and causing the increased circumference at the equator.
