Tides cause the poles of Earth to be pulled closer to each other than they would otherwise be.

Question

Quizplus · Accepted Answer

Tides are caused by the gravitational pull of the moon and sun on Earth's oceans, which creates a bulge in the water. This bulge causes the water level to rise and fall, creating high and low tides. This gravitational pull also affects the solid Earth, causing it to slightly deform and bulge towards the moon and sun. This means that the poles of the Earth are slightly closer to each other than they would be without the gravitational pull of tides.
