What causes slight flattening of earth at two poles?
Answers
The Earth has poles which are flattened because of the centrifugal force that acts on its poles while it rotates.
The rotating of the earth in the angles makes it also bulge at the equator.
The earth rotates at an immense amount of speed, at about 1000 miles per hour.
A rotation is completed in 24 hours.
Due to the great speed, there occurs a flattening of the surface near the poles.
We know that the Earth spins around itself at tremendous speed. This spinning results in an outward centrifugal force which is highest at the equator and gradually decreases to zero at the pole.
This results in slightly greater gravitational pull at the poles than at the equator. This causes the equator to bulge outward and the poles to flatten slightly.
Hope this helps!
