Final answer:
The Bay of Fundy experiences large tidal changes due to the gravitational pull of the moon.
Step-by-step explanation:
The MOST likely reason for the tides in the Bay of Fundy rising and falling so much is the gravitational pull of the moon. The tides are influenced by the gravitational force between the Earth, the moon, and the sun. When the moon is closer to the bay, its gravitational pull creates a high tide, and when the moon is farther away, a low tide occurs. This phenomenon is known as tidal bulge.
