Final answer:
The inequality in heights is not significant when the moon is over the equator due to the small tidal distortion of the solid Earth caused by the moon's gravitational forces. This distortion creates measurable tidal bulges in the oceans but does not affect solid objects on land.
Step-by-step explanation:
The inequality in heights is not significant when the moon is over the equator because the tidal distortion of the solid Earth, caused by the moon's gravitational forces, is only about 20 centimeters at its greatest.
This small distortion does not affect solid objects like humans or rocks on Earth's surface, but it does affect the waters in the oceans, creating measurable tidal bulges.
Therefore, the height inequality is not noticeable on land when the moon is over the equator.
