This occurrence takes place because the moon revolves around the Earth in the same direction that the Earth rotates around its axis.
High tides are commonly unequal in height due to the axial angle of the Earth's rotation. For example, the location on the Earth has a fairly large, high tide. But then if this position rotates in let's say, 12 hours to the other side, the high tide is no longer as high.
- On the far side, the gravitational pull of the moon is weaker because it is farther away.
- On the far side, the force of inertia is greater than the gravitational pull, and thus, it bulges.
