+Final answer:
The position of the tidal bulges on Earth is determined by the ecliptic.
Step-by-step explanation:
The position of the tidal bulges on Earth is determined by the ecliptic. The gravitational force of the Moon causes ocean water to flow into two tidal bulges on opposite sides of Earth. As Earth rotates, it passes through these bulges, resulting in high and low tides. The ecliptic refers to the path of the Sun in the sky as seen from Earth, and it also plays a role in determining the position of the tidal bulges.
